Kaolin as a gemstone polishing powder, stone polishing powder of the basic requirements are: maximum particles less than 3.5 m, hardness greater than or equal to the hardness of stones. Kaolin is mainly composed of kaolin, is pure white, the hardness is 1 ~ 3, easy processing to the fineness of less than or equal to 3.5 mu m. In the process of calcination of kaolinite with increasing temperature, will produce different phase, the hardness is improved, calcined to 1100 to 1150 DEG C, polishing hardness is less than or equal to 7 to 7.5 of the gem (such as amethyst, Huang Jing, malachite, quartz, apatite, moonstone, sun stone, olive stone etc.). Therefore, the use of pure kaolin can produce gem polishing good performance, such as spinel quartz or cristobalite mullite powder polishing, the polishing effect with conventional chromium oxide polishing powder is.
?
But when the calcination reaches 1250 or higher temperature, the polishing powder has obvious sintering phenomenon, affects the polishing powder operation and the polishing effect, therefore, the calcination temperature should be controlled below 1250 degrees celsius. In addition, with the gem polishing powder from kaolin production and commonly used polishing powder (such as chromium oxide, cerium oxide) compared with the advantages of no pollution, harmless to the human body, the gem does not pollute the environment, conducive to the coordinated development of gem processing industry and environmental protection.
