Embodiment

[0012] The preparation technology of alkali-resistant PTFE fiber of the present invention, PPS fiber blended needle-punched felt comprises the following steps, step 1, fiber opening, 50%PTFE fiber+50%PPS fiber raw material is weighed according to proportioning, the opening machine first Carry out preliminary loosening, loosen the large fiber clusters, and at the same time make the PTFE fibers and PPS fibers in the raw materials uniformly mixed, and then carry out fine opening, further loosen the fibers, mix the fiber components, fully open, mix evenly and try to Avoid fiber damage. Step 2. Fiber carding. After the fiber is opened and fully mixed, it enters the air pressure cotton box and is ready to be fed into the carding machine. After entering the carding machine, the fiber is carded through the interaction between the stripping roller and the cylinder, and is finally processed by the doffer Transfer out to form a fiber web, this time the carded fiber web is a light and thi...

Abstract

The invention belongs to the technical field of industrial dedusting application and particularly discloses a preparation technology of alkali-resisting PTFE (polytetrafluoroethylene) and PPS (polyphenylene sulfide) fiber blended needled felt. The preparation technology comprises following steps: step 1, fiber opening; step 2, fiber carding; step 3, lapping; step 4, needling compaction; step 5, postprocessing: (1), calendering; (2), singeing; (3), impregnation with an emulsion; (4), high-temperature setting; (5), film covering. The preparation technology of the alkali-resisting PTFE and PPS fiber blended needled felt has beneficial effects as follows: 1, a PTFE fiber+PPS fiber needled felt filter material is a filter material with a stereoscopic fiber structure, and the filter material isformed by covering two sides of base cloth with stereoscopically staggered PTFE fibers and PPS fibers respectively, compacting and fixing the base cloth and then needling the base cloth by a needlingmachine; 2, the needled felt filter material has a small bore diameter, low filtration resistance, good breathability and high dust capturing efficiency. The filtration efficiency can reach 99.99% orabove.

Description

technical field [0001] The invention belongs to the technical field of industrial dust removal application, and in particular relates to a preparation process of alkali-resistant PTFE fiber and PPS fiber blended needle-punched felt, which is used in a glass kiln. Background technique [0002] Glass melting furnace refers to thermal equipment used to melt glass batch materials in glass manufacturing. The powder prepared according to the glass composition and the added clinker (broken glass) are melted at high temperature in the kiln, clarified and formed into a glass liquid that meets the molding requirements. The production process of the glass kiln in the application of dust removal is relatively complicated, because the temperature of the kiln working condition is relatively high, and the acid content of the soot in the production process is relatively high, so the requirements for the filter bag are relatively high. [0003] Based on the above problems, the present inven...
