Problems solved by technology

The current mixing machine in corundum production is relatively simple and relatively inefficient. On the one hand, various materials are first put into the mixing machine in proportion, and then taken out from the mixing machine after the mixing is completed, and the mixed material enters the next production process. , time-consuming and labor-intensive; on the other hand, the environmental pollution caused by dust in the mixing process is relatively serious

Abstract

The invention discloses a preparation process of low-sodium corundum, which belongs to the field of corundum production process and equipment. It is characterized in that the required raw materials include the following components in terms of mass: industrial alumina, acetic acid or boric acid, ammonium chloride and alumina. The present invention can scientifically reduce the sodium content in the corundum product through reasonable process design and improve its various performances; while maintaining the production efficiency, the present invention can reduce the environmental pollution caused by the mixing link in the corundum production process.

Description

technical field [0001] The invention belongs to the field of corundum production technology, and in particular relates to a preparation technology of low-sodium corundum. Background technique [0002] Corundum, whose name originated from India, is a mineralogical name. Corundum is a kind of aluminum oxide (Al 2 o 3 ) crystallized gemstones. Pure corundum is colorless, but it shows different colors when it contains different trace elements. The Mohs hardness of corundum is 9, which is the second highest hardness substance found in nature so far, second only to diamond. Among the many types of corundum products, low-sodium corundum has low sodium content, so that the melting point, particle density, bending resistance, and pressure resistance of corundum products can meet the requirements of high-performance refractory materials and high-performance abrasives. Due to the high sodium content of industrial alumina used in the production of corundum, how to reasonably reduce ...
