Perforated ceramic Ball

Perforated ceramic ball is concave-convex the new product which sends in the inert porcelain ball foundation, it carries on the hole take the spheroid diameter as the axle center, both has like inert porcelain ball such certain mechanical strength, the chemical stability and the thermostability, and increased has compared the surface area and the percentage of voids, thus increased the material dispersivity and the flux, reduced the system resistance. This product since has put in the market, widely applies in profession substitution inert porcelain balls and so on the petroleum, chemical industry and natural gas makes the catalyst the support cover padding, deeply user high praise.
