Problems solved by technology

[0016] Judging from the above-mentioned patents, the formulations are unreasonable, such as the use of metal detergents and ashless dispersants, or the use of easily hydrolyzed antioxidants, resulting in defects in the performance of the compressor oil composition under this compatibility, such as oil-water separation Long time (poor anti-emulsification performance), poor oxidation resistance in the presence of high oil temperature, water and metal catalysts, that is, shortened service life, increased wear of parts, etc.; or does not specify the patent applied for quality grade etc.
