Porcelain clay filter material

   Porcelain clay filter material is featured with stable chemical properties,wear resistance,shock resistance,corrosion resistance,high temperature resistance,large specific surface area,stong wastewater stopping capability,good adsorption property,uniform grains,proper specific gravity and long service life to overcome the defect of single specific grarvity of natural filter material(such as quartz sand)and avoid secondary pollution caused by sillicon dioxide and organic carbon produced by the pelitization of natural filiter material which is easy to break.
