Polyorganosiloxanes. Liquid Base of High Temperature Consistent Oils

摘要

A comparative characteristic is given of polyorganosiloxane liquids, offering an interest in role of liquid base of high temperature consistent lubs. Polymethylsiloxane liquids as components of lubs, intended for operation at a temperature of 200C, have the advantage in comparison with polyethylsiloxane liquid (physico-chemical properties, thermooxidation stability, antiwear properties) and with polymethylphenylsiloxanes (viscosity-temperature and antiwear properties). For silicon lubs, intended for operation at a temperature of above 200C, polymethylphenyl and polymethyl chlorophenylsiloxanes are recommended. (Author)
