Production process for spunlace composite high temperature-resisting and corrosion-resisting filtering material

Abstract

The invention relates to a production process for a spunlace composite high temperature-resisting and corrosion-resisting filtering material and belongs to the technical field of a textile filtering material. The production process comprises the following steps that: taking polyphenylene sulfide fibers and fiberglass fabrics as raw materials; checking, weighing and charging the polyphenylene sulfide fibers; charging the polyphenylene sulfide fibers into a long curtain, a horizontal opener, a big-cabin cotton blending box and a refined opener successively; and then carding by using a carding machine I and a carding machine II in a layering mode; placing into a cross lapping machine I and a cross lapping machine II to lap; clamping the fiberglass fabrics between the raw materials delivered by the cross lapping machine I and the cross lapping machine II and performing superposition; and performing the processes of pre-wetting, hydroentangling, dehydrating, drying and taking-up. The production process for the spunlace composite high temperature-resisting and corrosion-resisting filtering material provided by the invention has the advantages of excellent mechanical performance, filtration performance, high temperature-resisting performance, and chemical corrosion-resisting performance and size stability.

Description

technical field [0001] The invention relates to a production process of a spunlace composite high-temperature-resistant and corrosion-resistant filter material, which belongs to the technical field of textile filter materials. Background technique [0002] With the progress of society, people's living standards have been significantly improved. However, while high-tech brings wealth and a more convenient and comfortable life, it also brings many problems to the natural environment on which human beings depend. The environmental pollution caused by high-temperature dusty waste gas discharged from coal-fired power plants, steel industry, cement chemical industry, etc. has brought more and more harm to human survival and health. China's "Eleventh Five-Year Plan" puts forward the idea of ​​greatly increasing power generation capacity. It is necessary to increase the installed capacity of power generation to 910 million kilowatts by 2020, including thermal power generation of 60...

Problems solved by technology

Studies have shown that in the needle punching process, steel needles with hooks puncture the fiber web for entanglement and compounding, which will cut off a large number of fibers and reinforce the filaments of the base fabric, resulting in inevitable damage to the base fabric, which will eventually cause a decrease in the mechanical strength of the filter material and affect the final filter. Lifespan of the bag

At the same time, due to the influence of the level of industrial development in China, high-temperature resistant filter mats imported from abroad are generally used. The import price is expensive, and restricted by the current economic development conditions, the popularization and use are limited.
