Smooth and the classification of the fat

There are many varieties and grades of smooth fat, its classification method also has many kinds. Have classified by root oil composition, such as divided into smooth smooth fat fat synthetic oil oil foundation; Some according to use classification, such as divided into polished and fat, protective fat reduction and sealing grease; Some fat according to smooth a feature classification, such as high temperature grease and hardy fat and extreme pressure grease, etc. On the basis of GB7631 country norms. 1 the smooth agent and related products ( L） The classification of class local 8: X group ( Smooth fat) ', in November 1991, the standard for GB7631. 8. This specification applies only to smooth all kinds of equipment, machinery parts and automobile, etc all kinds of smooth, does not apply to special use ( Such as contact food, radiation, high vacuum, etc. ) Smooth and the classification of the fat. A smooth before fat with a set of ( 5) Capital English letters code says, for example, L - XBEGB00 each letter has its specific meaning. See table 1 below smooth fat ( X group) Stop the classification is based on using properties, are shown in table 2 below in table 3 letters (4 Water pollution) According to the condition of table 3 for sure.

(2) L said no rust; M says fresh water in the presence of rust; H says the presence of brine of rust protection. According to the rules above, a smooth and fat, in the following conditions apply, given the smooth grease marks: for example the lowest operating temperature: - 20℃； The highest operating temperature: 160 ℃; Environmental conditions 2 support washed; Rust protection: no demand rust; Load conditions: high load; Level of consistency: 00. This kind of smooth grease marks should be: L - XBEGB00。 Can see, this kind of smooth fat taxonomy, and previous classification have bigger difference, the international organization for standardization ( 1SO) Once confirmed, start execution. Habits, are still using thickener types taxonomy, namely soap base grease, alkyl ester, organic and inorganic fat fat.
