Abstract

The invention relates to a novel production method for a mixed grinding material. The method comprises the following steps: mixing zirconium silicate and alumina; carrying out ball milling on the mixture so as to obtain mixed micro-powder; putting the mixed micro-powder, water and a dispersant into a sorting barrel and standing the mixture for settlement after stirring; carrying out sorting, wherein two sub-steps are included, namely, a) sucking out a slurry on the upper layer of the sorting barrel with a siphon, adding clear water to the sorting barrel until the mixture reaches the initial liquid level before siphoning, and carrying out stirring, settling and siphoning so as to obtain particles of a grade, and b) adding the dispersant and clear water into the sorting barrel until the mixture reaches the initial liquid level before siphoning and repeating the steps of stirring, settling and siphoning so as to obtain particles of another grade; drying the obtained particles with different grades so as to obtain a finished product. The mixed grinding material produced in the invention enables damage of micro-powder to the surface of a ground material in grinding to be substantially reduced and plays a very critical role in improving the quality of surface polishing of an object and in reducing polishing cost.

Description

technical field [0001] The invention relates to a micropowder production method, which is a production method of a mixed abrasive material for improving the grinding surface quality, and belongs to the technical field of micropowder production. Background technique [0002] In the process of surface grinding, because of the contact between the grinding powder and the surface of the object, it will inevitably cause damage to the surface of the object. The degree of damage will affect the efficiency of the subsequent process, especially the quality and cost of polishing the surface of the object. In the prior art, the surface quality of the object is controlled by controlling the proportion of the abrasive during the grinding process, but the effect of this method is not satisfactory. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a production method of a novel hybrid abrasive material, whi...
