Description

Inert alumina ceramic ball is widely used in many fields,such as petroleum,chemical engineering,fertilizer,smelting, medical treatment and environmental protection.Being the covering and supporting material and tower packing for catalyst in the reactor,ceramic ball has the feature of high temperature and plessure resistance,low water absorption,and stable chemical performance.It can not only resist the corrosion from the acid,alkali and other organic solvent,but also the temperature change in production process.The main role of ceramic ball is to increase the distributing spot of gas or liquid,also support and protect the activated catalyst with low strength. Some of its main performance indices are given to you for a reference as follows: specific gravity g/cm3 :2.**2.4 Water absorption % : Thermal conductiveity Kcal/mhdegree :>/= 0.7 Heat resistance degree: ********0 Specific heat Cal/g degree: 0.***0.2 Quenched experiment degree: *****0 Never crack in three times Acid resistance % : >/=*9
