Embodiment 1

[0020] A modified glass fiber dust removal material, which is prepared according to the following process: step 1) crushing and grinding, step 2) cationic starch modification, step 3) stirring and heating, step 4) mixing, step 5) stirring, spraying and drying;

[0021] Specifically, it is prepared according to the following process:

[0022] Step 1) Crushing and grinding: add zeolite and sepiolite to the crusher in turn for crushing, then mix with bentonite, and then grind to obtain a powder with a particle size of 200 mesh, which is the mixture 1; the zeolite, sea foam The mass ratio of pumice and bentonite is 2:2:1;

[0023] Step 2) Cationic starch modification: Add deionized water to the cationic starch, stir evenly to obtain a suspension, then add the mixture 1 obtained in step 1), stir at 500 rpm for 10 minutes, then let it stand for 6 hours, and filter to collect the precipitate , drying the precipitate at 50°C, and finally pulverizing to obtain Mixture 2; wherein, the...

Abstract

The invention belongs to the technical field of environmental protection, and discloses a modified glass fiber dust-removing material. The material is prepared through the following processes of crushing and grinding, cationic starch modifying, stirring and heating, even mixing and stirring, spraying and drying. According to the modified glass fiber dust-removing material, by modifying glass fibers, the adsorbing and dust-removing effects are improved, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a modified glass fiber dust removal material. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. Because of its small particle size, it is rich in a large amount of toxic and harmful substances, so it has a greater impact on human health and the quality of the atmospheric environment. PM2.5 represents the content of such particles per cubic meter of air, and the higher the value, the more serious the air pollution. In addition, during the manufacturing process of painting of industrial parts, coating of plates, etc., harmful exhaust gases containing acid or alkali, tiny particles, and unpleasant odors are also produced, and these exhaust gases are sometimes discharged into the atmosphere without treatment . ...
