Degreasing powder AR-815 (dedicated cleaning powder for drill bits) is a strongly alkaline compounded industrial cleaning agent designed by Haian Guoli Chemical Co., Ltd. for metal drill bits and precision parts. Its formulation system is scientifically rigorous, with synergistic effects among the components, enabling rapid penetration, stripping, and dissolution of various stubborn greases, cutting fluids, anti-rust oils, and grinding paste residues, especially suitable for heavy-duty oil contamination conditions that traditional solvents find difficult to handle.
The core components of this product cover three key stages in the cleaning process: alkaline additives are responsible for saponifying and decomposing animal and vegetable oils and acidic contaminants; soft water dispersants improve the stability of the cleaning solution by chelating calcium and magnesium ions in hard water, while dispersing the stripped oil contaminants into the solution to prevent secondary deposition; special surfactants reduce interfacial tension, enhance penetration and emulsification ability, quickly removing oil contaminants from the metal surface.
In the formulation, fatty alcohol polyoxyethylene ether (nonionic surfactant) and sodium dodecylbenzene sulfonate (anionic surfactant) are specially selected for compounding, balancing alkali resistance stability with excellent detergency and emulsification performance, enabling the product to maintain high cleaning efficiency even in strong alkaline environments.
| Component Category | Specific Component | Main Function |
|---|---|---|
| High-efficiency Alkaline Additive | Sodium Carbonate (Na₂CO₃) | Provides alkalinity, saponifies and decomposes animal and vegetable oils and acidic dirt |
| High-efficiency Alkaline Additive | Sodium Metasilicate Pentahydrate (Na₂SiO₃·5H₂O) | Enhances alkaline buffering capacity, with corrosion inhibition and dispersion functions |
| Soft Water and Dispersant | Sodium Tripolyphosphate (Na₅P₃O₁₀) | Chelates calcium and magnesium ions to soften water, disperses oil contaminants to prevent redeposition |
| Special Surfactant | Fatty Alcohol Polyoxyethylene Ether (AEO series) | Nonionic surfactant, provides excellent penetration and emulsification ability |
| Special Surfactant | Sodium Dodecylbenzene Sulfonate (LAS) | Anionic surfactant, enhances detergency and foam stability |
The above five core components form a triple synergistic cleaning mechanism: saponification (sodium carbonate, sodium metasilicate convert fatty acid oils into water-soluble soaps), emulsification (fatty alcohol polyoxyethylene ether and sodium dodecylbenzene sulfonate emulsify mineral oils into tiny oil droplets dispersed in water), chelating and dispersing (sodium tripolyphosphate complexes metal soap scale and hard water ions, preventing oil re-deposition on the workpiece surface). The synergy of these three mechanisms ensures thorough removal of oil contaminants from complex geometric surfaces such as drill bit helical flutes and cutting edges.
