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

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 fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate (specialty surfactants). 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.

Technical Parameters

Application Recommendations

Degreasing Powder AR-815 is mainly used in the following scenarios:

• Degreasing cleaning of metal drill bits: Applicable to various materials such as high-speed steel drill bits, carbide drill bits, and tungsten steel drill bits, effectively removing cutting oils, anti-rust oils, and processing fluid residues; supports multiple cleaning methods including spraying, ultrasonic, or immersion.
• Pre-treatment of precision cutting tools: Suitable for alkaline degreasing of taps, milling cutters, and other tools before coating, electroplating, or heat treatment, improving coating adhesion and surface treatment quality.
• 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.
