Walnut shell filters material
一． [pore-forming materials] walnut shell particles
Our factory using foreign advanced technology specialized in vitrified bond grinding wheel hole porosity materials - walnut shell grains. Compared with the old pore-forming material*- refined naphthalene, our product has uniform pores, and it is odorless, non-polluting, easy to use, inexpensive and safe. Moreover, the pore size of the grinding wheel can be arbitrarily selected. Thus, in *0 years abroad, it has been widely adopted in dustry.
