What Is an Rust-preventive Additive In Lubricant and Metalworking Fluid?
Anti-rust additives are chemical compounds incorporated into lubricants and metalworking fluids (MWF) to protect metal surfaces from corrosion. The anti-rust additive is also called: rust inhibitor, rust preventive, and corrosion inhibitor. They are wily used in engine oils and MWFs.
Classification Of Anti-Rust Additives
Generally, according to the characteristics of the solution, Rust Preventives can be divided into water-soluble Rust Preventives, oil-soluble Rust Preventives, emulsified Rust Preventives, gas-phase Rust Preventives, and wax film-type Rust Preventives.
Sulfonates, the general chemical formula is (R-SO3) metal surface treatment additives. Generally, alkali metal or alkaline earth metal salts of petroleum sulfonic acid are used, such as barium petroleum sulfonate, sodium petroleum sulfonate, barium dinonylnaphthalenesulfonate, etc.
In the actual application of anti-rust agents, several anti-rust agents are often used in a compound formula to enhance their anti-rust effect.
The antirust agent can be applied to: the lubrication and antirust of general guide rails, pin shafts, hydraulic props, bearings, suspension chains, etc., especially suitable for equipment and parts that cannot be cured by heating, such as large equipment, non-metallic materials, etc. It is also suitable for the lubrication and rust prevention of machinery left in the open air, naval equipment (aircraft, ships) that are often exposed to seawater smoke, and mechanical equipment that is often in acid, alkali, high and low-temperature environments.
Some anti-rust agents are also suitable for spraying on the machining surface and grinding surface of various carbon steel, alloy steel, copper, aluminum, magnesium, and their alloys, cast iron, non-metallic materials, etc., and can also be sprayed on the surface of metal material workpieces that have been sandblasted, phosphating, passivated, anodized, and sulfur-nitrocarburized.
