Abstract

The invention discloses a method for preparing polishing powder for onyx polishing, which is characterized in that the method has the following process steps: in the reactor, add according to the following composition mass percentage concentration, lead powder: 5-8% , compound: 80~88%, tin oxide: 5~13%, the sum of each component is 100%, turn on the grinder, grind at a speed of 500 rpm for 30~60min, and obtain agate polishing powder, in which the compound Contains nano aluminum nitride, aluminum oxide, zirconium oxide, iron oxide, cobalt oxide. The preparation process is simple, the conditions are easy to control, the production cost is low, and the industrial production is easy. In the polishing process, it has good powder polishing effect, high gloss, no scratches, high flatness, and less powder consumption.

Description

technical field [0001] The invention relates to the technical field of preparation of polishing powder, in particular to a preparation process of polishing powder for onyx polishing and its use in agate polishing. Background technique [0002] Agate is a kind of chalcedony, which can be understood as the crystal mineral of unfinished jade. It has the texture of jade, but not strong. The surface of agate is smooth, while the surface of jade is frosted and smooth. Then you can look at the color. Agate is a crystal, and its light transmission is better than that of jade, so agate shows a bright light and has various colors. It is often a striped block mixed with opal and aphanitic quartz, with a hardness of 6.5-7 degrees, a specific gravity of 2.65, and a quite layered color. Available in translucent or opaque. The original form of trigonal crystal system. It is often dense and massive and forms various structures, such as breast-shaped, grape-shaped, nodular, etc., and th...
