Lubricating and cooling fluids (COOLANT) are complex multicomponent compositions that are mainly intended for cooling and lubricating parts and metalworking tools.
Lubricating and cooling fluids (COOLANT) are complex multicomponent compositions that are mainly intended for cooling and lubricating parts and metalworking tools.
They help to increase the precision of machining parts and reduce tool wear.
During the processing of materials, these compounds also perform a number of other functions: they protect machined parts and equipment from corrosion, wash out abrasive chips and dust, and contribute to improving sanitary and hygienic working conditions.
Based on the components used, there are three main groups of coolant: Pure mineral oils and oils with the addition of extreme pressure and anti-wear additives.
Antioxidant, anti-foam and anti-corrosion additives are also added to them.
Aqueous lubricating and cooling emulsions of mineral oils obtained at the place of consumption by diluting emulsifiers with water, which consist of 40-80% oils and 20-60% binders, bactericides, emulsifiers, antifoam agents, corrosion inhibitors.
Aqueous solutions of low molecular weight polymer and surfactant chemical compounds.
Coolant is obtained by compounding (mixing) the base base with additives.
They are mainly used in metalworking by pressure and cutting, in the processing of cermets and plastics.
The choice of coolant in each individual case depends on the type and mode of processing, the properties of the materials and tools being processed, the method of liquid supply, the requirements for the quality of the treated surface, etc.
