The production steps of acupuncture non-woven fabrics
Based on polyester, polypropylene raw materials, processed by carding, combing, pre-needled main acupuncture. Center plus mesh sandwich, and then double-channel nuclear management, airlaid acupuncture compound into cloth, after press cloth having a three-dimensional structure by heat setting, after singeing the surface most chemically oil processing, the filter cloth the appearance of smooth, uniform pore distribution, on the surface density of the product is good, smooth surface on both sides and a good degree of permeability, filtering uses proven in the compressor frame, you can use high-strength pressure filtration precision up to 4 microns or less, according to user the need to provide the two materials of polypropylene and polyester. Practice has proved that the non-woven filter cloth frame filter press better performance when: Slurry handling cases of coal preparation plant, steel plant wastewater treatment. In the brewery, printing and dyeing wastewater treatment. If there are other specifications filter cloth filter cake pressure quit, and difficult problem of falling, non-woven cloth, the filter cake in the filter unit when the pressure reaches 10kg-12kg is quite dry, while open frame filter press cake It will automatically fall off. Users in the choice of a non-woven fabric, mainly based on the amount of ventilation, filtration precision, elongation to consider different thickness, the quality of non-woven cloth, polyester product parameters please needle felt and polypropylene needle felt, specifications varieties are It can be developed.
