Application of nano diamond in lubricating oil
The surface treatment method of nanodiamond particles an additive in lubricating oils, comprising the following steps, with a high-speed air stream at a high speed collision of the nano-diamond powder superfine grinding collision, untied agglomerates; will unlock The agglomerated nano-diamond particles are added to an organic solvent having a surface modifier and a dispersing agent; high-speed shearing is performed in an organic solvent to which the nano-diamond particles are added by using a high-speed shearing machine, and ultrasonic waves are used to make microbubbles in the organic solvent. The internal explosion is ultrasonic cavitation, which further de-agglomerates the nano-diamond particles; the surface-modified nano-diamond particles are separated by centrifugation, the nano-diamond particles are washed with an organic solvent, and the nano-diamond particles are centrifuged to obtain a surface. Modified nanodiamond particles. The technical effect of the present invention is that the refined nano-diamond particles have a particle size ranging from 20 to 60 nm, and the surface modification of the nano-diamond particles is very sufficient.
