Embodiment 1

[0030] Graft 3-aminopropylmethyldimethoxysilane, polyoxyethylene castor oil and maleic anhydride at 90 degrees and stir for 1 hour, then add isophorone diisocyanate, stir at 110 degrees for 80 minutes, then add Ethylene-vinyl acetate copolymer and benzisothiazolinone, stirred at 140 degrees for 2 hours, cooled to room temperature to obtain a mixture; the mixture, polytetrafluoroethylene particles, methyltrimethoxysilane, dialkyl di Pyridine thiophosphoric acid, triethylenetetramine, and hydroxyl-terminated polybutadiene are mixed with a mixer to form a uniformly dispersed mixture; then the mixture is heat-treated at 180 degrees and 2 MPa for 2 hours; then at 235 degrees, the The heat-treated mixture is granulated by an extruder to obtain a plastic composition, that is, a plastic composition for a plastic filter pipe;

[0031] The plastic composition is mixed with polyurea formaldehyde and paraffin to obtain a raw material composition for plastic filter pipes, which is added to...

Embodiment 2

[0034] Using the preparation method of Example 1, the reinforcing ring is located in the pipe body, and is connected to the pipe body through a reinforcing rod; the cross section of the pipe body is a gear-shaped structure; the tooth top and tooth groove of the gear-shaped structure are arc-shaped structures; The ring is located at one end of the tube body; there are 8 reinforcing rods; the contact points between the reinforcing rods and the reinforcing rings are evenly distributed on the reinforcing ring; the reinforcing rods are of flat structure (thickness is 3% of the length); The tooth groove of the gear-shaped structure; the length of each reinforcing rod is the same; the angle of the arc-shaped structure is 150 degrees; the height of the teeth of the gear-shaped structure is 28% of the length of the reinforcing rod; the above-mentioned structures are all conventional geometric structures.

[0035] After several actual measurements, the dust removal rate of the plastic fi...

Abstract

The invention discloses a plastic filter tube and a plastic composition for the plastic filter tube. The plastic composition is prepared by 3-aminopropyl methyldimethoxysilane, polyoxyethylated castor oil, maleic anhydride grafting, isophorone diisocyanate, an ethylene-vinyl acetate copolymer, benzisothiazolone, polytetrafluoroethylene particles, methyltrimethoxysilane, bialkyl pyridine dithiophosphate, triethylene tetramine, and hydroxyl-terminated polybutadiene. The plastic composition is mixed with polyurea formaldehyde and paraffin so as to obtain a raw material composition for the plastic filter tube, and the raw material composition for the plastic filer tube is added to an injection molding machine for preparing the filter tube. The provided plastic filer tube belongs to a rewashed environment-friendly product. A traditional filter bag device can be directly replaced without modifying a current dust collecting plant. In addition, the service life of the device is long, and the service life is more than 10 times greater than that of the traditional device.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a plastic filter pipe and a plastic composition used for the plastic filter pipe. Background technique [0002] With the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. Dust pollution is effectively controlled. In recent years, the country has paid more and more attention to environmental protection and the phenomenon of global warming has become serious. In order to advocate energy saving and carbon reduction, the environmental protection industry is booming. It has become the consensus of all to develop and purify the living environment of human beings. The existing filter tubes are only flat, and the folded ends of the filter tubes are divided into pointed and square. The existing plastic filter tubes have dead angles for pulse cleaning, resulting in poor cleaning effect and ...
