Porcelain Inert Alumina Ceramic Ball High Alumina Ceramic Ball
Inert alumina packing ball is widely used in petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection industries, as the support material of catalyst in reactor and tower packing. It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature change in the production process. Its main function is to increase the distribution point of gas or liquid, support and protect the active catalyst with low strength.
