Embodiment 1

[0017] 1. Drawing:

[0018] First, raise the temperature of the wire drawing machine to 250°C, add 50kg of polypropylene into the suction hopper, start the suction valve, melt the polypropylene, and extrude it from the 230 pores of the spinneret through the rod to become a melt filament; then It is cooled into a solid filament; it is drawn through a cooling tank, and then enters an air heating box at 150°C for a second draft and then wound onto a bobbin to obtain a 0.13mm monofilament;

[0019] 2. Warp: through the section warping machine, the monofilaments are neatly arranged on the warp bobbin according to the length required by the process, and poured on the warp beam as required.

[0020] 3. Weaving: put the finished loom on the machine through heald reed, warp and weft are woven into monofilament cloth through P7100 Sulzer projectile loom, during which, according to the process requirements, the warp is 0.13mm Monofilament, the warp density is 230 threads / inch, the weft ...

Abstract

A piece of nanometer anti-sticking filtering cloth is provided specially for purification and smelting process in metallurgical industry and is an industrial small-aperture filtering cloth used for filtering particles with sizes smaller than five micrometers. The nanometer anti-sticking filtering cloth is manufactured through the processes as follows: a, wire drawing, b, twisting, c, fabric manufacture, d, after finishing and the like. The nanometer anti-sticking filtering cloth is novel filtering cloth which is made of material with stable physical and chemical properties, manufactured through manufacturing technologies of wire drawing, warping, fabric manufacture, shaping and press polishing, and applied to the filtration and separation technology. The product integrates three processes, namely shaping, press polishing and emulsion coating, so that production cost is reduced, energy consumption is reduced, and labor intensity of workers is reduced. The product provided by the invention has the advantages that the product needs to be cleaned only after being used constantly for 30 days, so that the service cycle of the filtering cloth is prolonged; and polytetrafluoroethylene emulsion is applied on the surface of the filtering cloth, so that the surface of the filtering cloth is smooth and is not adhered with filter cakes, apertures of the filtering cloth are not easily blocked, and the service life of the filtering cloth is greatly improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a filter cloth for tiny particles used in refining and smelting processes, in particular to a nano anti-adhesive filter cloth. Background technique [0002] In the filter equipment using filter cloth, the filter cloth is the heart of the filter equipment. Without the filter cloth, the filtration work of solid-liquid separation and air purification cannot be realized. Most of the filter media used in the purification and smelting process of the metallurgical industry are traditional woven filter cloths such as P840AB and P4147 with a bubbling pore size of more than 50 microns. When the cake is caked, the filter cake and the filter cloth stick to each other and it is not easy to unload the cake. After two or three days of use, the plate and frame must be removed for cleaning due to the clogging of the aperture, which increases the labor intensity of the workers and reduces the ser...
