Oil Removal Powder AR-815 is a strongly alkaline industrial cleaner that works through the synergistic action of saponification, emulsification, and chelating dispersion, specifically designed for metal drill bits and precision components. It features three core characteristics: strong stripping, broad-spectrum degreasing, and chelating anti-precipitation.

Detailed Description

The core advantage of Oil Removal Powder AR-815 lies in its strong stripping capability. For carbon deposits and sticky oils formed on the spiral grooves and cutting edges of drill bits due to high-temperature and high-pressure machining, this product has excellent penetration and dissociation performance, allowing it to quickly and thoroughly remove heavy oil stains that traditional solvents struggle with. This characteristic makes it perform excellently on various materials such as high-speed steel drill bits, carbide drill bits, and tungsten steel drill bits.

Its broad-spectrum degreasing performance is equally outstanding. Whether it is mineral-based cutting oils, synthetic ester rust inhibitors, or solid grinding waxes and other processing residues, AR-815 can handle them simultaneously, providing a one-stop solution for composite oil contamination. In addition, the built-in chelating anti-precipitation system effectively complexes calcium and magnesium ions in hard water and metal soap scales, preventing oil stains from redepositing during the cleaning process, ensuring the workpiece surface is clean and shiny without water marks or stains.

In formulation design, AR-815 integrates high-efficiency alkaline additives (sodium carbonate, sodium metasilicate pentahydrate), water softeners and dispersants (sodium tripolyphosphate), and specialty surfactants (alcohol ethoxylate, sodium dodecylbenzenesulfonate), achieving synergistic enhancement between inorganic additives and organic surfactants, ensuring both degreasing power and formulation stability and easy rinsing.

Application Suggestions

AR-815 is suitable for spray, ultrasonic, or immersion and other industrial cleaning methods, and its application scenarios include:

  • Degreasing of metal drill bits and cutting tools: Surface degreasing cleaning of high-speed steel drill bits, carbide drill bits, tungsten steel drill bits, taps, and milling cutters, especially suitable for stubborn oil stains in spiral grooves and cutting edges.
  • Precision component cleaning: Degreasing pretreatment of precision bearings, automotive parts before assembly, plating, spraying, or heat treatment, enhancing coating adhesion and surface treatment quality.
  • Pretreatment for painting/plating: Alkaline degreasing of various high-precision cutting tools before surface treatment, ensuring subsequent process effectiveness.

Precautions

  • Strong alkaline protection: During operation, must wear alkali-resistant gloves (nitrile or neoprene), closed chemical splash goggles or full-face shield, and chemical-resistant protective clothing throughout.
  • Correct dilution sequence: When preparing solution, always slowly add powder to a measured amount of cold water with continuous stirring. Never pour water into dry powder to avoid splash injuries from localized heat.
  • Isolation from incompatible substances: Do not mix with strong acids; keep away from aluminum, zinc, and other amphoteric metals and their alloys to avoid violent reactions or hydrogen generation.
  • Storage requirements: Store in a cool, dry, well-ventilated warehouse, strictly isolated from moisture and humidity. Immediately reseal after opening to prevent deliquescence and caking.
  • First aid measures: Skin contact: flush with plenty of running water for at least 20 minutes. Eye contact: flush continuously for 15–20 minutes and seek immediate medical attention. Ingestion: do not induce vomiting; immediately call a poison control center or emergency medical care.
