Black biochemical filter cotton is mainly used in aquarium filter and air filter , it made ​​from foam sponge made ​​with irregular layered uniform pore size , the smaller the aperture , the better the filter , opposite the greater the resistance . General aquarium biological filtration with a black cotton are within 30PPI more compact filter in the filter with pore size of the sponge is about 50PPI. Air filter with pore size of most of the black filter sponge 35PPI-60PPI, because the air filter requires a slightly higher level than a small aquarium filter , smaller particles in the air .

 

Black biochemical filter cotton features : full aperture , high tensile strength , good permeability , flexibility, speed, dust , dust rate, low flow resistance , good ventilation properties, good chemical resistance and other properties . Is ideal for the production of air filters , oil filters , aquarium filter industry , and the production of ceramic foam filters, filter plates , filters , filter necessities are available upon request processed into a cylindrical , hollow , square and other the special shape of the molding process and to OEM ; can be cleaned , washed effect does not deteriorate . Also has good permeability and strong mechanical strength , as a filter material having a small flow resistance , a high filtration efficiency , and can be washed repeatedly displayed from durable, environmental and economic advantages.
