What are the options for stainless steel plate cutting fluid additives?

Reasonable addition of cutting fluid is a necessary process when cutting stainless steel plates. However, how to give full play to the role of cutting fluid and make satisfactory products when cutting stainless steel plates will test the processor's familiarity with the components of the cutting fluid and the corresponding additives.

The additives used in cutting fluids are certain chemical substances added to adapt to various usage requirements and optimize the performance of the cutting fluid. The content of additives in cutting fluid is very low, only about 0.01%-5%. Common additives are mostly chemical substances, including oily additives, extreme pressure additives, surface active additives and other additives.

The oily additive contains polar molecules, which can form a strong adsorption film on the surface of the stainless steel plate, but it cannot withstand high temperatures and pressures, and can only achieve relatively good lubrication at relatively low cutting speeds. Oily additives mainly include animal oils, vegetable oils, fatty acids, amines, alcohols, lipids, etc.

Extreme pressure additives contain organic compounds such as sulfur, phosphorus, chlorine, and iodine. They react chemically with the surface of the stainless steel plate at high temperatures to form a chemical lubricating film that can withstand higher temperatures and pressures. This lubricating film can withstand very large pressure, and can also avoid direct contact with the stainless steel plate interface, reduce the friction factor, and ensure excellent cutting lubrication conditions.

Surfactants are emulsifiers, which have emulsifying and lubricating effects. The former will emulsify mineral oil and water when mixed to form an emulsion; the latter will adsorb on the surface of the stainless steel plate to form a lubricating film. Commonly used surfactants mainly include sodium petroleum sulfonate, sodium oleate soap, etc., which have excellent emulsifying properties and have certain cleaning, lubrication and anti-rust properties.

In addition to the above additives, there are other types of additives. For example, anti-rust additives, anti-foam additives and anti-mildew additives, emulsifying additives, solubilizing additives, etc.

Choosing appropriate additives to add to the cutting fluid can better improve the cutting effect. However, it should be noted that although anti-mold additives have the effect of sterilizing and inhibiting bacterial reproduction, they can easily cause skin allergies in the operator, so this additive should be used sparingly.
