3:Short introduction :
Chemshun Inert balls are to increase the distribution spots of gas or
liquid , widely utilized as the covering or supporting materials of the catalyst in the reactors
and the packing in the column in such varies areas as petroleum , chemical industry ,
chemical fertilizer,support or protect the active catalyst , which especially
have the comparatively lower mechanical strength
