Walnut shell is a kind of degreasing, crushing, screening and other processing processed granule, uses the high quality of pecan shell as raw material, after crushing, polishing, steaming, washing, drug treatment, two filter processing.Surface pores, adsorption filter material with better effect, walnut shell strength big, wear-resisting compressive strength, strong adsorption capacity, oil immersion, agglomerate, not rot, stable chemical properties, does not contain toxic substances.Is the natural roll material and light polishing abrasive, using it to do abrasive, won't destroy the workpiece surface polishing effect is good wait for an advantage. A, walnut shell used as filter material Walnut shell filter material products are widely used in oil field, chemical industry, leather and other industrial wastewater treatment and urban water supply and drainage engineering, is also the most ideal water purification filter material of various filters. Second, the walnut shell used as abrasive Walnut shell polishing materials mainly used in glasses accessories, pearl jewelry, buttons, electronic parts, stamping parts, industries such as polishing deburring, excellent wear resistance, uniform particle size, high content of shell.Walnut shell is a kind of natural material of rolling light, use it to do abrasive, won't destroy the workpiece surface polishing effect is good. Third, walnut shell pore forming material Ceramic bond, stomatal wheel into porous materials with uniform porosity, no smell, no pollution, easy to use, cheap, without damage to the body on the use of employees, safety, and can choose to the grinding wheel blowhole size.
