BIt is high that value is obviously wanted, when additive capacity is 1.5%, and the P of content additive oil sample
BValue is for 620N, than the P of base oil
BValue 260N is high about 140%, and this explanation SCL additive can significantly improve the supporting capacity of lubricating oil.Can find out also that from Fig. 5 there is a peak in this additive add-on, beginning increases with the additive add-on, contains the supporting capacity of additive oil sample, i.e. P
BValue improves, and contains the P of additive oil sample when surpassing certain value
BValue has decline on the contrary slightly, and test conditions drops to 560N, still than the P of base oil
BValue 260N exceeds 115%.This phenomenon possibly be that excessive additive makes in the formed abrasion resistant film organic composition increase and reduced film strength, thereby its supporting capacity is reduced.
(6) low friction compound and load are to the lubrication oil antiwear Effect on Performance:
The low friction compound addition is seen shown in Figure 6 to the influence of wear scar diameter.Result shown in Figure 6 shows that the adding of low friction compound can significantly reduce wear scar diameter, and especially effect is more obvious under lower concentration, as adds 0.5% low friction compound, and wear scar diameter is reduced to 0.60mm from 0.75mm, reduces by 20%.
(7) different loads to base oil with contain the influence of the wear scar diameter of 2% low friction compound oil sample:
Test-results shows under Fig. 7 different loads; Wear scar diameter strengthens with load; But under equal load; All the wear scar diameter than base oil is little to contain the wear scar diameter of low friction compound oil sample, shows that the abrasion resistance of oil sample under various load that contains this additive all is superior to base oil, and this this additive of explanation can significantly improve the abrasion resistance of base oil.
