Functions of Metal Working Fluid (MWF)：
lubrication, cooling, chip removal, and rust prevention for metal cutting, grinding, forming, and other metal processing methods.
Metal processing fluids are divided into oil-based metalworking fluids and water-based metal-working fluids as per the base fluid.
Common additives for oil-based metalworking fluids |
|
| Additive types | Chemical Compound |
| Oiliness Agent | Animal oil, vegetable oil, fatty acid, higher fatty alcohol, synthetic ester |
| Extreme Pressure Antiwear Additive | Chlorinated paraffins, chlorinated fats, sulfurized fats, sulfurized olefins, sulfurized mineral oils, thioethers, phosphate esters, phosphite esters and super basic sulfonates (PEP) |
| Antirust Additives | Sulfonate, carboxylate, naphthenate, phosphate, borate, molybdate, polyol ester, carboxylic acid, amine, benzotriazole, thiazole, etc |
| Antioxygen Additives | Shielding phenols, amines, sulfur-containing compounds |
| Anti-smog Additives | Ethylene propylene copolymer (OCP) and polyisobutylene(PIB) |
| pour point depressant (PPD) | Alkyl naphthalene, polymethacrylate (PMA) |
| Anti-foamer | Silicone, acrylic copolymer |
