What is degreasing powder AR-815, dedicated cleaning powder for drill bits

Degreasing powder AR-815 is a strongly alkaline industrial cleaning agent specially designed for metal drill bits and precision components. Through the triple mechanisms of saponification, emulsification, and chelating dispersion, it can quickly and thoroughly remove various stubborn greases and processing residues.

Detailed Description

Degreasing powder AR-815 (also known as alkaline degreasing powder, metal degreasing powder, industrial heavy oil stain cleaning powder, AR-815 cleaning agent) is a high-performance industrial cleaning product launched by Haian Guoli Chemical Co., Ltd. It appears as a white to slightly yellow uniform powder with good fluidity, no lumps, and is easy to dissolve and mix. This product is specifically designed for carbon deposits and adhesive greases on the spiral grooves and cutting edges of metal drill bits, exhibiting excellent cleaning effects under heavy oil stain conditions that are difficult for traditional solvents to handle.

From the formulation mechanism, AR-815 integrates three core component systems: high-efficiency alkaline additives (sodium carbonate, sodium metasilicate pentahydrate) provide strong saponification capability, converting grease into soluble soaps; special surfactants (fatty alcohol polyoxyethylene ether, sodium dodecylbenzene sulfonate) perform emulsification and penetration functions, reducing the interfacial tension between oil and metal surfaces; softeners and dispersants (sodium tripolyphosphate) act as chelating agents, effectively complexing calcium and magnesium ions in hard water and metal soap scales, preventing re-deposition of oil, ensuring the workpiece surface is clean and residue-free after cleaning.

Typical application scenarios of AR-815 include surface degreasing of metal drill bits, taps, milling cutters, and other cutting tools, degreasing of precision bearings and automotive parts before assembly, and it is suitable for various cleaning methods such as spraying, ultrasonic, or immersion. Particularly for high-speed steel drill bits, carbide drill bits, and tungsten steel drill bits, this product can efficiently remove cutting oils, anti-rust greases, grinding pastes, and metalworking fluid residues without damaging the base material.

Technical Parameters

Application Recommendations

Dedicated Degreasing Cleaning for Metal Drill Bits:

• Cleaning High-Speed Steel Drill Bits: Efficiently removes cutting oils, anti-rust greases, and metalworking fluid residues. Supports various cleaning methods such as spraying, ultrasonic, or immersion.
• Degreasing Carbide Drill Bits: Quickly decomposes and strips stubborn oil stains and grinding pastes, achieving deep degreasing, maintaining the sharpness and surface cleanliness of the drill bit cutting edges.
• Oil Removal Treatment for Tungsten Steel Drill Bits: Mild alkaline formula does not damage the tungsten steel matrix, thoroughly removes oil stains and dirt, providing a clean surface for subsequent processes.

Alkaline Degreasing for Precision Tools and Workpieces:

• Suitable for degreasing pretreatment of various high-precision tools before coating, electroplating, or heat treatment, improving coating adhesion and surface treatment quality.
• Quickly removes anti-rust oils and processing greases from bearing surfaces, ensuring assembly precision and operational reliability.
• Meets the surface degreasing requirements of automotive metal parts before electroplating, spraying, or heat treatment, achieving high cleanliness standards.

Recommended Cleaning Methods: Spray cleaning, ultrasonic cleaning, and immersion cleaning are all suitable. Specific concentration and temperature parameters should be determined through small-scale tests based on actual working conditions.

Precautions

• Strong Alkaline Protection: During operation, always wear alkali-resistant gloves (nitrile rubber or neoprene, thickness ≥0.4mm), airtight chemical splash goggles or full-face shield, anti-corrosion work clothes, and safety shoes.
• Solution Preparation Order: When diluting, slowly add the powder to a quantitative amount of cold water while continuously stirring. Never add water to the dry powder to prevent local overheating causing splashing.
• Incompatible Materials: Do not mix with strong acids. Avoid contact with aluminum, zinc, and their alloys to prevent corrosion and possible release of hydrogen gas.
• Skin/Eye Contact: In case of skin contact, immediately rinse with plenty of water for at least 20 minutes. If splashed into eyes, rinse continuously for at least 15–20 minutes and seek emergency medical attention.
• Storage Conditions: Store in a cool, dry, well-ventilated warehouse, sealed tightly. Strictly keep away from moisture and humidity to prevent caking. Store separately from strong acids and reactive metals.
• Waste Disposal: Dispose of as hazardous waste according to classification. Do not discharge into sewers or mix with ordinary garbage. Neutralize to meet standards before discharge.
