Manufactory Inert porcelain alumina ceramic ball for catalyst bed support media
Production Introduction
Inert alumina ceramic ball has the characteristics of high strength, low water absorption, high chemical stability, high thermal stability, resistance to high temperature and high pressure. It can not only resist the corrosion from the acid, alkali, salt and other organic solvent, but also the temperature change in production process.
Inert alumina ceramic ball is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the supporting and covering material of catalyst in reactors. Its main role is to increase the distributing spot of gas or liquid, also support and protect the activated catalyst with low strength.
Typical Application: Be mainly used in the petroleum, chemical industry, fertilizers,natural gas, environmental protection and other industries. It plays a role of supporting and compacting the packing of the tower.
Warranty: By National Standard HG/T 3683.1-2014 .
Free consultation during the warranty period.
Normal Package: 25KG/Plastic bag;1300KG/Super sack. Steel drum.
