August 16, 2022
Needle punched non woven fabric: It is a kind of dry - laid nonwoven fabric. The needle punched non woven is a puncture effect of a lancet, and the fluffy fiber web is reinforced into a cloth.
Needle punched nonwoven is made of polyester and polypropylene raw materials, which are carded, combed, pre - acupuncture and main acupuncture. The center is added with a mesh interlayer, and then double - channeled, air - laid acupuncture composite into a cloth, the post - pressure filter cloth has a three - dimensional structure, after heat setting, after singeing, the surface is most chemically treated to make the filter cloth. 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. When selecting the nonwoven filter cloth, the user mainly considers the nonwoven filter cloth of different thickness and quality according to the air permeability, filtration precision and elongation.
