Polyalkylene glycols, monoether type polyglycols, and diether type polyglycols having two or more groups have been used. Furthermore, polyester base oils have been used which have better lubricity than polyglycol base oils.

The base is cut and reacts with the sliding member to generate chloride, and the combined effect of the chloride and the phosphorus-based extreme pressure additive significantly improves the sliding properties.

It has been found that wear resistance is improved by the combined effect of the formation of iron phosphate (formation of iron phosphate) and the action of chloride generated when the chlorine Cl group contained in Freon reacts with the sliding member on the sliding surface.
By adding chlorine CZ groups to polyester-based frozen oil, when the same oil reaches extreme pressure conditions, chloride is generated on the sliding surface, and when used in combination with a phosphorus-based extreme pressure agent, the combined effect improves wear resistance. It is calculated by

By replacing the polyester oil on the sliding surface with extreme pressure, some of the chlorine C2 groups are cut off and react with the sliding member to produce chloride. The combined effect with phosphorus-based extreme pressure additives greatly improves the sliding properties, and the improvement in lubrication properties is particularly noticeable in compressor durability tests and wear resistance tests. We have realized a frozen oil manufacturing system that has less wear and tear on sliding surfaces than other frozen base oils.
