The appearance is smooth and the micropores are evenly distributed. The density of the product is good from the surface. The surface of both sides is smooth and breathable. The filtration on the plate and frame compressor proves that high - strength pressure can be used, and the filtration precision is up to 4 microns. Both polypropylene and polyester materials are required. Practice has proved that the non woven filter fabric has better performance in the frame frame filter press: the coal slurry treatment in the coal plant, the wastewater treatment in the steel plant, and the wastewater treatment in the brewery and printing and dyeing plant. If other filter cloths are used, the cake pressure will appear. If it is not dry and it is difficult to fall off, after using the filter fabric non woven, the filter cake will be quite dry when the filter pressure reaches 10kg - 12kg, and the filter cake will fall off automatically when the filter is opened.
