RZH-8
The purpose of industrial oils is to reduce the friction and wear of parts of metal cutting machines, presses, rolling mills and other industrial equipment. Simultaneously, industrial oils must remove heat from friction units, protect parts from corrosion, clean friction surfaces from contamination, be a sealing agent, prevent the formation of foam when in contact with air, prevent the formation of persistent emulsions with water or be emulsified, filter well through filter elements , be non-toxic, do not have an unpleasant odor, etc.
Oil specification Liquid RZH-8:
Liquid RZh-8 (TU 38.101964-83) is a low-viscosity, deeply hydrogenated fraction of sulphurous oils. They are used as a working fluid in EDM machines of medium and high power, and also as lubricating and cooling liquids for turning and finishing operations of machine assembly production. It is possible to use RJ-8 as a diluent of dioctyl phthalate used in the production of polyvinylchloride three-pronged linoleum linoleum on a fabric basis.
