Preparation process of efficient filter cotton used for coating

Abstract

The invention discloses a preparation process of an efficient filter cotton used for coating. The preparation process comprises the following steps: S1, cotton mixing: matching fiber according to preset proportion as required, weighing initial weight and then pouring into a stirrer to be stirred by rotation of a machine; S2, opening; S3, carding: carding to uniform thickness, delivering a uniformly distributed cotton layer to an upper screen, and paving into a net by a shaking screen; S4, net paving: swinging in a reciprocating way by the shaking screen, paving into a uniform net layer and then sending into an oven by a bottom screen; S5, sizing with hot air: enabling low-melting-point fiber to cohere various fibers together so as to form synthesized cellucotton; S6, sizing with cold air and trimming and curling: enabling the synthesized cellucotton to be subjected to sizing with cold air, then determining the thickness of the cellucotton by a pressure shaft, then trimming with a preset value, cutting off with a thermofuse after the length reaches a preset value, and then coiling. The filter cotton in the field of high-grade paint coating, prepared by the method provided by the invention, is formed by mixing two-dimensional and three-dimensional superfine fibers, and such fiber has antibacterial and germicidal effects.

Description

Technical field [0001] The invention relates to a preparation process of high-efficiency filter cotton for coating. Background technique [0002] Air filtration, or air filtration, refers to the nearly complete removal of pollutant particles in the air. It is further than air purification. Air purification is suitable for many industrial processes where the requirements for the treatment of polluted air are not too strict. Air filtration technology is a comprehensive technology gradually formed with the development of science and technology and modern industry in the past 100 years. It refers to the application of air purification equipment to control the pollution of fine dust and fine powder or to capture suspended particulates in the air through air circulation filtration. . To protect the environment and human health. It has been widely used in air conditioning, ventilation and dust removal and other fields. [0003] In addition to the quality of the coating material itself...

AI Technical Summary

Problems solved by technology

There are also suspended dust dust in the painting environment; dust particles accumulated in the ventilation duct; dust particles adhered to the surface of the spray booth, drying room, drying room and conveying device, flying on the wet paint film or other The surface of the coating; the dust brought in by the operator and the scattering of clothing fabric fibers are all killers that affect the quality of the coating

[0004] The existing coating filter cotton uses poor raw materials, the product material is light, and fails to achieve the corresponding effect, and the service life is short, easy to shed, has no antibacterial and sterilizing effect, and the mesh cloth is uniform, with black spots, spots, etc.
