Non-woven needle

      Based on polyester, polypropylene fiber raw material production, by the needle, combing, weaving cloth laminated machine centers, then the rationale of nuclear dual-channel, flow into a complex network of acupuncture into cloth, filter cloth after the pressure has a three-dimensional structure, by heat-setting , singeing, after the surface of most chemical agents so that the appearance of a smooth filter, pore distribution, the surface density of the product, and both the extent of smooth surface and good air permeability, the filter in the compressor frame use has proved that the product may be pressure to use high-strength, filtration precision of up to 4 microns or less, the product can be provided in accordance with user needs two kinds of polypropylene and polyester materials. Practice has proved that non-woven filter cloth in the plate and frame filter press at a better performance: cases of coal preparation plant processing, iron and steel plant waste water treatment, in the brewery, printing and dyeing mill wastewater treatment. Other specifications such as filter cake there will be pressure quit, but also the problem of falling hard, with non-woven filter cloth, the cake in the filter pressure to reach 10kg-12kg when quite dry, and the Filter box to open automatically when the cake fell off. Users in the selection of non-woven filter cloth, the principal amount of the basis of ventilation, filtration precision, and so the elongation of different thickness, the quality of the non-woven filter cloth, the product parameters,polypropylene  and polyester needle felt, specifications varieties can be formulated.
