Abstract

The invention discloses a method for preparing an antistatic and highly wear-resistant composite filter material. The method comprises the following steps: step 1, using steel fibers with different diameters as warps and polyethylene fibers with different diameters as wefts, using fiber Fabric felting machine is processed into fiber felt; step 2, dissolve activated carbon particles in organic solvent, cut by high-speed shearing machine for 5-8 minutes, then add nano-aluminum and castor oil, disperse under the action of ultrasound, and then add straw powder , form a uniform spinning solution, and prepare modified straw fibers by electrospinning technology; step 3, use fiber mat as the base material, weave the modified straw fibers into the fiber mat, and then immerse in the finishing agent at 20-30°C After finishing for 24-48 hours, dry it to get the composite filter material. The preparation method is simple and easy to operate. The obtained composite filter material is made of modified raw materials from a wide range of sources. It has strong antistatic ability and good air permeability. It is not only suitable for daily anti-smog products, but also for flue gas purification. .

Description

technical field [0001] The invention belongs to the field of flue gas filtration, and in particular relates to a preparation method of an antistatic and highly wear-resistant composite filter material. Background technique [0002] Environmental pollution brought about by rapid economic development is becoming more and more serious, which directly affects people's quality of life. As the country has become more and more strict on environmental protection, people have paid more and more attention to the comprehensive treatment technology of industrial smoke and dust pollution. Due to the advantages of high filtration efficiency and long service life, bag dust removal technology is more and more widely used in the field of industrial smoke and dust control. The filter material is a key component of the bag filter, and its performance determines the stability of the entire system. Therefore, the research and development of a filter material with antistatic and high temperatur...
