USE OF SURFACTANTS WITH LOW MOLECULAR WEIGHT FOR IMPROVING THE FILTERABILITY IN HYDRAULIC LUBRICANTS

A hydraulic oil, a predominant amount of an oil having a viscosity suitable for lubrication and from 0.03% to 0.06% of an agent improving filterability, corresponding to the formula R-Z. Z represents a polar group containing one or more substituents chosen from phosphoric esters, amides, ethers, ami...

Zusammenfassung:A hydraulic oil, a predominant amount of an oil having a viscosity suitable for lubrication and from 0.03% to 0.06% of an agent improving filterability, corresponding to the formula R-Z. Z represents a polar group containing one or more substituents chosen from phosphoric esters, amides, ethers, amino alcohols, ethoxylated amines, and mixtures thereof. R represents a lipophilic chain having 14 to 24 carbon atoms.
