Sintering-Resistance and Abrasion-Resistance Capacity of Phosphoric Acid Ester,
Abstract
The sintering-resistance and abrasion resistance capacity of both the neutral, acidic alkyl-phosphoric acid ester and the acidic-phosphoric acid ester amin was fully evaluated or measured by means of the fourfold globular test device. Scientific research on how the chemical composition of the phosphoric acid ester affects the sintering resistance and abrasion resistance capacity has also been conducted. As a result, it was found that the sintering resistance and the abrasion resistance capacity of the acidic phosphoric ester turned out to be the best among the phosphoric acid ester family. The acidic phosphoric ester amin salt was proven to be slightly inferior to the acidic phosphoric acid ester, and the neutral phosphoric ester was almost as good as the first two. It was also found that in the case of amin salt, the shorter the length of the alkyl group of the phosphoric acid ester and amin, the better.
