Question 1

Is the degreasing powder AR-815, a specialized cleaning powder for drill bits, harmful to the human body? Does it have an impact on the environment?

Accepted Answer

The degreasing powder AR-815 has clear hazards to the human body (classified as a dangerous chemical) and also has acute and chronic inhibitory effects on the aquatic ecological environment. Strict protection and standardized disposal are required. Detailed explanation of human hazards The degreasing powder AR-815 is a strongly alkaline industrial cleaning agent, and the pH value of its 1% aqueous solution is as high as 12.0–13.5. According to the product safety data sheet, this product has been officially classified as a dangerous chemical, with hazard pictograms GHS05 (corrosive) and GHS07 (exclamation mark), and the signal word is "Danger". This means that during normal use, if appropriate personal protection is lacking, it may cause clear harm to the human body. Specifically, this product has three types of clear hazards to the human body: Skin corrosion/irritation (Category 2)——contact can cause skin redness, swelling, burning pain, and even chemical burns; Serious eye damage/eye irritation (Category 1)——this is the highest level of eye damage classification, and splashing into the eyes can cause irreversible corneal damage or even blindness; Respiratory tract irritation (Category 3)——dust or mist generated during operation, if inhaled, may cause coughing, throat irritation, and respiratory discomfort, and long-term or high-concentration exposure poses a risk of delayed pulmonary edema. The product contains sodium carbonate, sodium metasilicate pentahydrate, and surctants (tty alcohol polyoxyethylene ether, sodium dodecylbenzene sulfonate), all of which are confirmed irritants. During operation, it is necessary to wear alkali-resistant protective gloves (nitrile or neoprene material, thickness not less than 0.4mm), sealed chemical splash goggles or a full-ce shield, and use in a well-ventilated area. In case of skin or eye contact, immediately rinse with plenty of running water for at least 15–20 minutes and seek emergency medical attention without delay. Detailed explanation of environmental impact The environmental impact of degreasing powder AR-815 is mainly reflected in its high alkalinity characteristics. The product safety data sheet clearly indicates that high-pH wastewater has acute toxicity and chronic inhibitory effects on aquatic organisms (including fish, plankton, and benthic organisms). Even after dilution, if the cleaning wastewater without neutralization treatment enters natural water bodies, it will drastically change the acid-base balance of the local waters, disrupting the normal functions of the aquatic ecosystem. In addition, the product formulation contains sodium tripolyphosphate as a water softener and dispersant, which, when discharged in large quantities, may exacerbate the eutrophication process of receiving water bodies, indirectly leading to secondary ecological problems such as excessive algae growth and water hypoxia. Therefore, it is strictly prohibited to discharge used wastewater directly into municipal pipelines or natural water bodies without treatment. All cleaning wastewater must be collected and then undergo neutralization treatment (adjusting pH to the legal discharge standard range of 6–9) and professional wastewater treatment processes before being discharged in compliance. Waste products and contaminated containers must be classified, recycled, and disposed of according to hazardous waste regulations.

When diluting, strictly follow the principle of "adding powder to water"——slowly add the powder to cold water while stirring, and never reverse the operation to avoid local overheating and splashing. Cleaning wastewater must be collected centrally, neutralized (adjust pH to meet standards), and discharged according to industrial wastewater regulations; do not pour directly. Discard packaging materials according to hazardous waste management; do not reuse or mix with household waste. Store away from strong acids, amphoteric metals such as aluminum/zinc, and heat sources; keep the warehouse dry and well-ventilated. Emergency treatment key points Skin contact: Remove contaminated clothing, rinse with running water for at least 20 minutes, do not use hot water. Eye contact: Hold eyelids open, continuously rinse with water or saline for at least 15–20 minutes, call for emergency medical help, and do not delay. Inhalation: Move to fresh air, keep in a semi-sitting position; if breathing is difficult, immediately give oxygen and seek medical attention. Ingestion: Do not induce vomiting; rinse mouth and give a small amount of water or milk (only if conscious), seek immediate medical attention and present this product safety data sheet.

Question 4

Does the degreasing powder AR-815, a special cleaning powder for drill bits, meet environmental requirements? Can a test report be provided?

Accepted Answer

The degreasing powder AR-815 needs to be treated to meet standards before discharge. The product itself does not contain prohibited substances, but an environmental test report cannot be directly provided at the moment. Please contact the sales department of Guoli Chemical for the latest compliance documents. Detailed Explanation The environmental compliance of the degreasing powder AR-815 (special cleaning powder for drill bits) needs to be understood from two aspects: formula compliance and waste treatment. According to the Guoli Chemical product database, this product is formulated with sodium carbonate, sodium metasilicate pentahydrate, sodium tripolyphosphate, tty alcohol polyoxyethylene ether, and sodium dodecylbenzenesulfonate. These surctants are biodegradable and do not contain substances of very high concern (SVHC) under EU REACH regulations or ozone-depleting substances (ODS) prohibited by international conventions. The formula itself meets current green chemical raw material access requirements. It is particularly important to note that the 1% aqueous solution of this product has a high pH value of 12.0–13.5, making it strongly alkaline. The high pH has acute and chronic inhibitory effects on aquatic organisms. Therefore, the washing tank wastewater must not be directly discharged into municipal pipelines or natural water bodies without thorough treatment. The correct treatment process is as follows: First, the wastewater must be neutralized by adding acid (such as dilute sulfuric acid or dilute hydrochloric acid) to adjust the pH to the legal discharge standard range of 6–9. If necessary, flocculation and sedimentation should be used to remove washed-off oils and metal soap scum. Then, a sample should be taken for testing to confirm that key indicators such as COD, total phosphorus, and pH meet the standards before being discharged into the pipe network. Regarding the test report, the current Guoli Chemical product database does not archive third-party environmental test reports for this product (such as VOC content, biodegradability rate reports, or ROHS/REACH test reports). As an industrial B2B chemical supplier, Guoli Chemical can provide corresponding quality inspection reports (COA) or commission third parties for specific project tests based on customer needs and procurement batches. However, such documents are usually not directly available for download on the website. Ways to Obtain Test Reports Technical Parameter Confirmation: You can refer to the quality inspection report (COA) provided at the time of product shipment, which covers key batch data such as active content (≥99%), pH of 1% aqueous solution (11.0–12.5), and moisture content (≤5.0%). This serves as a basic basis for product consistency. Customized Testing Needs: If you require ROHS ten items, REACH-SVHC, biodegradability rate (such as OECD 301B), or wastewater treatment feasibility assessment reports, please directly contact the technical sales department of Guoli Chemical. We can assist in contacting third-party testing institutions with CMA/CNAS qualifications to issue special reports based on your export destination or end customer audit requirements. On-site Technical Support: If you need an environmental compliance assessment of the cleaning production line or a wastewater treatment solution design, Guoli Chemical can arrange for technical engineers to conduct on-site inspections and provide supporting wastewater treatment operation instructions. Precautions If you are only concerned about whether the formula contains phosphorus before purchase: This product uses sodium tripolyphosphate as a water softener and dispersant, so it has a certain amount of phosphorus content. If your ctory is located in a region with strict total phosphorus discharge limits (such as the Taihu Lake basin, Dianchi Lake basin, and other ecologically sensitive areas), please consult Guoli Chemical in advance for phosphorus-free alternatives or confirm the discharge limits accepted by the local wastewater treatment plant to avoid exceeding emission standards.

Question 5

What are the advantages of degreasing powder AR-815, a special cleaning powder for drill bits, compared with other similar products?

Accepted Answer

AR-815 is a strong alkaline cleaning powder specially designed for drill bits, utilizing a synergistic triple mechanism of "saponification + emulsification + chelating dispersion." Compared with common alkaline degreasing powders on the market, its core advantages lie in its deep penetration and stripping ability for carbon deposits and sintered residues in drill bit spiral flutes, as well as adhesive heavy oil stains, its broad-spectrum degreasing compatibility, and its built-in chelating anti-deposition system. Detailed Description Degreasing powder AR-815 was developed by Guoli Chemical specifically for heavy oil contamination on metal drill bits and precision cutting tools. Its differentiated competitiveness first lies in the precision of its formulation design. The product uses sodium carbonate and sodium metasilicate pentahydrate to build an efficient alkaline base, combined with sodium tripolyphosphate as a water softening and dispersing agent, and is compounded with a dual-component surctant system of tty alcohol polyoxyethylene ether (non-ionic) and sodium dodecylbenzene sulfonate (anionic). According to the product database, the effective content of this formulation is ≥99%, and the solid content is ≥95%, r higher than common filler-type degreasing powders on the market (some competing products have only 70%-85% active content), which means more concentrated active cleaning ingredients per unit dosage and higher oil removal efficiency. Unlike most general-purpose alkaline degreasing powders on the market that rely solely on simple alkaline washing or emulsification mechanisms, AR-815 achieves a triple synergistic effect of saponification, emulsification, and chelating dispersion: alkaline additives saponify animal and vegetable oils and tty acid esters into water-soluble soaps; tty alcohol polyoxyethylene ether and sodium dodecylbenzene sulfonate emulsify and disperse mineral oils and synthetic esters by reducing surce tension (approximately 30-35 mN\/m at 1% concentration); and sodium tripolyphosphate chelates calcium and magnesium ions in hard water as well as metal soap residues, preventing redeposition of oil stains. This mechanism is especially effective for stubborn stains composed of carbon deposits, sintered residues, and cutting fluid mixtures in the spiral flutes of drill bits—ordinary degreasing powders often can only handle surce oil films and il to penetrate the bottom of flutes and the root of cutting edges. Furthermore, AR-815 also has significant advantages in material adaptability and foam control. Its formulation takes into account three mainstream drill bit materials: high-speed steel, carbide, and tungsten steel, and is non-corrosive to tungsten steel substrates. It produces low to moderate foam, making it suitable for various industrial cleaning methods such as spray, ultrasonic, and immersion cleaning, avoiding the overflow and equipment blockage problems caused by high-foam formulations in spray systems. In contrast, some low-cost degreasing powders on the market have unstable foam control or pose a risk of micro-corrosion to the cobalt binder phase in carbide, whereas AR-815 has been specially optimized for drill bit applications.

It is recommended for use with ultrasonic cleaning tanks or spray cleaning lines. The typical concentration is 3%-8% (by weight), with optimal performance at temperatures between 50-80°C. It also performs excellently for degreasing pretreatment before electroplating, painting, or heat treatment of precision bearings and automotive parts. When comparing options, if the current general-purpose alkaline degreasing powder exhibits issues such as residual oil film at the bottom of drill bit flutes after cleaning, substandard edge gloss, short cleaning solution life requiring frequent replacement, or excessive foam affecting spray system operation, switching to AR-815 can significantly improve cleaning yield. Precautions This product is strongly alkaline. Wear alkali-resistant gloves and protective goggles during operation. Slowly add the powder to water when preparing the solution; never add water to the powder. Not suitable for cleaning aluminum, zinc, or other amphoteric metals and their alloys, as it may cause corrosion and release hydrogen gas. Store sealed, away from moisture. Use promptly after opening to prevent moisture absorption and caking that may affect solubility. Neutralize waste liquid to pH compliance before discharge. Do not discharge directly into natural water bodies.

Question 6

How to store Degreasing Powder AR-815, Drill Bit Cleaning Powder? What is the shelf life?

Accepted Answer

Degreasing Powder AR-815 should be stored in a cool, dry, well-ventilated dedicated warehouse, strictly protected from moisture and sunlight, kept in original sealed containers. The shelf life is typically 12 months (refer to product packaging for details, follow FIFO principle). Detailed Description Degreasing Powder AR-815 (Drill Bit Cleaning Powder) is a strongly alkaline powdered product with deliquescent properties—it easily absorbs moisture and clumps in humid air, and releases hydration heat upon contact with water. Therefore, moisture prevention is the core of storage management. The storage area must have alkali-resistant, leak-proof flooring, effective containment dikes, away from drains, living areas, and heat sources, maintaining a constant low temperature, strictly isolating from water vapor, steam, and condensation. For packaging management, the product must be kept in original alkali-resistant containers, completely sealed and stored upright. After each use, reseal immediately to prevent powder exposure to air and moisture absorption. If packaging damage is found, transfer the product to a compatible safety container immediately. Do not continue using damaged packaging for long-term storage. Storage Requirements Overview Storage ElementSpecific Requirement Temperature ConditionMaintain constant low temperature, away from heat sources and direct sunlight Humidity ControlStrictly isolate from water vapor, steam, and condensation to prevent deliquescence Packaging StatusOriginal alkali-resistant container sealed and stored upright, reseal immediately after use Warehouse EnvironmentCool, dry, well-ventilated, with alkali-resistant leak-proof flooring and containment dikes Prohibited IsolationMust be stored separately from strong acids, peroxides, metal powders, aluminum/zinc and other amphoteric metals in designated areas Security ManagementWarehouse locked, display hazardous chemical signs and warning symbols, control personnel access Inventory PrincipleFollow FIFO (First In, First Out) to avoid indefinite stacking leading to packaging aging and ilure Shelf Life Explanation The Degreasing Powder AR-815 product database does not specify a specific shelf life in months. According to industry practice for alkaline industrial cleaning powder products, under strict compliance with the above storage conditions, the recommended use period for unopened original products is generally 12 months (from the date of manucture). For the specific shelf life, please refer to the product packaging. It should be particularly noted that the validity of the shelf life highly depends on storage conditions. If the storage environment exceeds humidity standards causing product deliquescence and clumping, or if packaging seal is damaged, product performance may significantly decline even before the stated shelf life. Therefore, it is recommended to follow the "First In, First Out" principle for inventory turnover to avoid long-term accumulation of products. Precautions Do not pour water directly into dry powder. When diluting, slowly add powder to a measured amount of cold water; otherwise, it may cause localized high-temperature splashing. Do not store with acidic substances. Contact between the two may cause a violent reaction and release a large amount of heat. The storage area must be equipped with emergency showers and eyewash stations, and kept ready for use at all times. Damaged packaging should be immediately transferred to a compatible safety container. Do not continue using original damaged packaging for storage. Empty containers must be drained of residues, treated according to the hazards of the contents, and not reused or discarded arbitrarily.

Question 8

How to use degreasing powder AR-815, special cleaning powder for drill bits? What is the recommended dosage?

Accepted Answer

Recommended dosage (use concentration) of AR-815 degreasing powder is 2%~10% (by mass), i.e., add 2~10 kg of powder per 100 kg of water, which should be flexibly adjusted according to the severity of oil contamination, cleaning method, and workpiece material. Detailed explanation AR-815 degreasing powder (special cleaning powder for drill bits) is a strong alkaline compound industrial cleaner launched by Guoli Chemical. Its core components include sodium carbonate, sodium metasilicate pentahydrate, and sodium tripolyphosphate, compounded with tty alcohol polyoxyethylene ether (nonionic surctant) and sodium dodecylbenzene sulfonate (anionic surctant). Its degreasing mechanism covers triple actions of saponification, emulsification, and chelating dispersion, providing excellent penetration and stripping ability for stubborn stains such as carbon sintered deposits in drill bit spiral grooves, cutting oil, anti-rust grease, and grinding paste. Regarding the dosage, according to the official safety data sheet and product parameters, the pH value of a 1% aqueous solution of this product reaches 12.0~13.5, which is strongly alkaline. Therefore, even at low concentrations, it has considerable degreasing efficiency. The conventional recommended use concentration is 2%~10%. For light oil contamination (e.g., anti-rust oil, light cutting fluid), 2%~4% is recommended; for moderate oil contamination (e.g., general processing oil), 4%~7% is recommended; for heavy oil contamination (e.g., carbon sintered deposits, sticky grease, grinding wax), 7%~10% is recommended. It should be noted that higher concentration does not mean infinitely improved cleaning effect; excessive use increases the difficulty of rinsing, raises the risk of corrosion to light metals, and generates more alkaline wastewater. When preparing the working solution, the operation principle of "slowly adding powder to a quantitative amount of cold water" must be strictly followed, while continuously stirring to cilitate dissolution and heat dissipation — it is strictly forbidden to pour water directly into dry powder, otherwise local violent hydration exothermic reaction can cause boiling splashing, leading to severe burns. The prepared working solution can be used in ultrasonic cleaning, immersion cleaning, or spray cleaning according to the working conditions. The cleaning temperature is recommended to be controlled at 50~70°C. Appropriate heating can significantly improve degreasing efficiency, but it is not recommended to exceed 80°C. After cleaning, thoroughly rinse with running clean water or deionized water to remove residual alkali on the workpiece surce, avoiding subsequent corrosion or affecting coating adhesion.

Immersion cleaning: Suitable for batch small and medium workpieces. Prepare 3%~10% working solution, temperature 60~70°C, soak for 10~30 minutes (extend depending on the degree of oil contamination), stir or circulate the bath solution periodically to enhance cleaning effect. 3. Spray cleaning: Suitable for assembly line operations. Prepare 2%~5% working solution, temperature 50~65°C, spray pressure 0.2~0.5 MPa. The low-foam formula effectively avoids foam overflow issues. Precautions Protective requirements: During operation, wear alkali-resistant gloves (nitrile or neoprene), sealed splash-proof goggles, and corrosion-resistant work clothes at all times. The workplace must be equipped with emergency showers and eyewash equipment. Material restrictions: This product is corrosive to aluminum, zinc, and other amphoteric metals and light metal alloys, and may release hydrogen gas. It is strictly prohibited for cleaning these types of materials. Preparation safety: Always add powder to water, never water to powder. It is recommended to use room temperature cold water for preparation to avoid violent heat release from hot water. Storage points: Store in a cool, dry, and well-ventilated place, away from strong acids, peroxides, and reactive metals. Reseal immediately after opening to prevent moisture absorption and caking. Rinsing and wastewater treatment: After cleaning, thoroughly rinse to remove alkali residue. Waste liquid must be neutralized to meet pH standards before discharge; direct discharge into municipal sewers or natural water bodies is strictly prohibited.

Accepted Answer

The degreasing powder AR-815 is mainly applied in fields such as metal cutting tool manucturing, precision parts processing, automotive manucturing, and bearing industry, with core processes covering degreasing before electroplating/coating, oil removal before heat treatment, and cleaning before assembly. Detailed Explanation Degreasing powder AR-815 is a strong alkaline industrial cleaning agent specially designed for metal drill bits and precision parts, and its application spans multiple core industries of metal processing and manucturing. In the tool manucturing industry, this product is an indispensable degreasing cleaner on the production line of high-speed steel drill bits, carbide drill bits, and tungsten steel drill bits, efficiently removing cutting oil, anti-rust grease, polishing paste, and carbon deposits from the spiral flutes and cutting edges. In the precision machining industry, the degreasing pretreatment of tools such as taps, milling cutters, and reamers before coating or heat treatment also relies on the deep degreasing capability of AR-815 to ensure the adhesion and processing quality of subsequent processes. In the automotive parts manucturing industry, AR-815 is widely used for surce degreasing processes of metal parts such as engine components, transmission gears, and brake system parts before electroplating, spraying, or heat treatment, meeting the stringent cleanliness standards of the automotive industry for parts. In the bearing industry, this product is used for cleaning various rolling bearings and sliding bearings before assembly, quickly removing anti-rust oil and processing grease, ensuring assembly precision and operational reliability. Additionally, in the general metal surce treatment industry, for degreasing processes before surce treatments involving painting, electroplating, phosphating, blackening, etc., AR-815 can serve as the core agent of an efficient alkaline cleaning solution. From a process adaptability perspective, AR-815 supports three mainstream industrial cleaning methods: spray cleaning, ultrasonic cleaning, and immersion cleaning. The spray process is suitable for high-volume assembly line operations; ultrasonic cleaning has unique advantages for degreasing deep holes and narrow slits of precision tools; the immersion process is often used for batch processing of small workpieces. Its triple decontamination mechanism of saponification, emulsification, and chelating dispersion can simultaneously address various processing residues such as mineral-based cutting oils, synthetic ester anti-rust oils, and solid polishing waxes, achieving a broad-spectrum degreasing effect of "one agent for multiple uses."

For carbide and tungsten steel drill bits, due to material characteristics, it is recommended to appropriately reduce temperature and control immersion time to avoid prolonged contact. Automotive Parts Processing: A spray cleaning line is recommended, with concentration 3%–6%, temperature 60–80°C, spray pressure 0.2–0.5 MPa. The treated workpieces must be thoroughly rinsed with clean water and quickly dried to prevent alkaline residues from affecting subsequent electroplating or spraying quality. For precision fit parts, it is recommended to use ultrasonic process for secondary fine cleaning. Bearing and Precision Parts: A multi-tank ultrasonic cleaning line should be used, with the initial cleaning tank concentration of 5%–8%, and after fine cleaning, rinse with deionized water. Pay attention to the placement of workpieces to cilitate solution circulation, avoiding overlapping that leads to cleaning dead spots. Precautions This product is strongly alkaline. Do not use on aluminum, zinc, or their alloys, as it may cause corrosion and release hydrogen gas. When preparing the solution, slowly add the powder into a measured amount of cold water. Do not pour water into the dry powder to prevent local overheating and splashing that could cause injury. Operators must wear alkali-resistant gloves, chemical splash goggles, and protective clothing throughout the operation. The workplace must be equipped with emergency showers and eyewash stations. Waste liquid must be neutralized and treated to meet standards before discharge. It should not be directly discharged into municipal pipelines or natural water bodies. Keep away from strong acids, peroxides, and active metals during storage. Keep the packaging sealed and store in a cool, dry place.

Question 10

What are the physicochemical technical parameters of Degreasing Powder AR-815, a special cleaning powder for drill bits?

Accepted Answer

Degreasing Powder AR-815 is a strongly alkaline compounded industrial cleaning powder with a 1% aqueous solution pH value as high as 12.0–13.5, exhibiting powerful degreasing and deoiling capabilities. The following are the detailed physicochemical technical parameters. Detailed Description Degreasing Powder AR-815 (special cleaning powder for drill bits) is a strongly alkaline industrial cleaning agent produced by Haian Guoli Chemical Co., Ltd., designed for metal drill bits and precision components. The product appears as white to slightly yellow uniform powder, with good flowability, no caking, and is easy to dissolve and formulate. Its cleaning mechanism relies on the synergistic effects of saponification, emulsification, and chelation dispersion, rapidly stripping and dissolving stubborn grease, cutting fluids, anti-rust oils, and grinding paste residues. From a chemical composition perspective, the core components of AR-815 include: sodium carbonate, sodium metasilicate pentahydrate (highly effective alkaline auxiliaries), sodium tripolyphosphate (water softener and dispersant), and tty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate (specialty surctants). This compounded system endows the product with excellent penetrating power and dissociation capability, while the built-in chelating agents can complex hard water calcium and magnesium ions as well as metallic soap scale, effectively preventing oil redeposition. It should be particularly noted that this product itself is non-flammable, boiling point and flash point are not applicable; its relative density and water solubility parameters are related to the specific formulation batch and no fixed values are available. In terms of storage, the product exhibits deliquescence, with the deliquescence rate directly affected by operational exposure time; therefore, after opening, it must be immediately resealed and stored in a cool, dry environment.

Cleaning of bearings and automotive parts: Quickly removes anti-rust oils and processing greases, meeting high cleanliness requirements before assembly, suitable for batch industrial cleaning processes. When preparing the working solution, it is recommended to slowly add the powder to a pre-weighed amount of cold water, stirring continuously to aid dissolution; do not pour water directly onto dry powder to avoid local overheating causing splashing. Precautions During operation, wear alkali-resistant protective gloves (recommended nitrile rubber or neoprene, thickness ≥0.4mm), enclosed chemical splash goggles, and corrosion-resistant workwear throughout. Strictly avoid mixing with strong acids to prevent violent reactions generating large amounts of heat; avoid contact with amphoteric metals such as aluminum and zinc, as well as light metals. When diluting, always add powder to water, never the reverse (water to powder), to prevent local overheating and splashing causing injury. Store in a cool, dry, well-ventilated warehouse, strictly isolating from moisture and steam; immediately reseal after opening to prevent deliquescence and caking. High pH waste liquid must be neutralized and meet legal discharge standards before being discharged; do not directly discharge into municipal pipelines or natural water bodies. In case of skin contact, rinse with plenty of running water for at least 20 minutes; in case of eye contact, keep eyelids open and rinse continuously for 15–20 minutes and seek medical attention immediately.
