Degreasing powder AR-815 is mainly composed of three categories of components: alkaline additives, soft water dispersants, and special surfactants, which achieve efficient degreasing through the triple mechanisms of saponification, emulsification, and chelating dispersion.

Detailed Description

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 CategorySpecific ComponentMain Function
High-efficiency Alkaline AdditiveSodium Carbonate (Na₂CO₃)Provides alkalinity, saponifies and decomposes animal and vegetable oils and acidic dirt
High-efficiency Alkaline AdditiveSodium Metasilicate Pentahydrate (Na₂SiO₃·5H₂O)Enhances alkaline buffering capacity, with corrosion inhibition and dispersion functions
Soft Water and DispersantSodium Tripolyphosphate (Na₅P₃O₁₀)Chelates calcium and magnesium ions to soften water, disperses oil contaminants to prevent redeposition
Special SurfactantFatty Alcohol Polyoxyethylene Ether (AEO series)Nonionic surfactant, provides excellent penetration and emulsification ability
Special SurfactantSodium Dodecylbenzene Sulfonate (LAS)Anionic surfactant, enhances detergency and foam stability

Mechanism of Action

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.

Application Recommendations

  • It is recommended to adjust the usage concentration according to the severity of oil contamination, typically prepared as a 1%~5% aqueous solution for use
  • Suitable for various industrial cleaning methods such as spray, ultrasonic cleaning, and immersion
  • Especially suitable for degreasing and cleaning after machining of HSS drill bits, carbide drill bits, and tungsten steel drill bits
  • Also can be used for surface degreasing pretreatment of precision bearings and automotive parts before electroplating, spraying, or heat treatment

Precautions

  • The 1% aqueous solution of this product has a pH of 12.0–13.5, strongly alkaline. Be sure to wear alkali-resistant gloves and protective goggles during operation
  • When preparing the solution, slowly add the powder to cold water while stirring. Never pour water into the dry powder to avoid local overheating and splashing
  • Do not mix with acidic substances to avoid violent reactions
  • Corrosive to amphoteric metals such as aluminum and zinc, not suitable for cleaning these materials
  • In case of contact with skin or eyes, immediately flush with plenty of water for at least 15-20 minutes and seek medical attention
