Raw materials and requirements about ceramic foam filter

Raw materials and requirements about ceramic foam filter: 

Ceramic foam filter uses ad 3D continuous network of foam plastic as the skeleton, after the impregnation of slurry you can do the high teperature baking. So the raw material of the filter board is divided into: foam and slurry.  The ceramic foam filter should have sufficient flexibility and strength to ensure that it is capable of resistance to damage when dipped in slurry. In the impregnation stage it does not have partial depression, cracks and other congenital deficiencies, The PPI (per inch pores) describes the parameters of the parameters of the foam specifications, which is the number of holes per inch.
