Manufacturing method for air purification and filtering skeleton supporting material

Abstract

The invention discloses a manufacturing method for an air purification and filtering skeleton supporting material and aims at providing a manufacturing method of a skeleton supporting material which is simple in manufacturing process, high in air permeability and stiffness and small in air resistance and does not have peculiar smell. The key points of the technical scheme are characterized in thatthe manufacturing method comprises the following steps of mixing PET fibers in different specifications, making base paper with pulp with a wet method by an inclined wire paper machine, and performing coating treatment. The manufacturing method is suitable for the technical field of indoor air purification material preparation.

Description

technical field [0001] The invention belongs to the technical field of preparation of indoor air purification materials, in particular to a method for manufacturing an air purification filter framework support material. Background technique [0002] With the development of society, the air pollution is getting more and more serious, and the smog in the city is getting more and more serious. With the continuous improvement of people's quality of life, the emphasis on health problems is also increasing, and the requirements for air cleanliness are getting higher and higher. High, household air purifiers are becoming more and more popular, and the selected air filter materials need to have superior filtration efficiency. Existing filter materials with high filtration efficiency are mainly composed of a layer of filter membrane with very high filtration efficiency compounded on the skeleton support material. The existing skeleton support materials are usually made by mixing plan...

AI Technical Summary

Problems solved by technology

Existing filter materials with high filtration efficiency are mainly composed of a layer of filter membrane with very high filtration efficiency compounded on the skeleton support material. The existing skeleton support materials are usually made by mixing plant fibers and chemical fibers, but the selection of plant fibers is not enough. Environmental protection; when a single specification of chemical fiber is selected, the poor fiber bonding strength will cause the base paper to have no strength, coating is difficult, and the dispersion of chemical fibers is worse than that of wood pulp fibers, resulting in poor paper evenness and large quantitative fluctuations; in addition, inorganic fibers are also used as materials, such as Glass fiber, but the cost of glass fiber is high, and there are still problems such as poor air permeability, resulting in large air resistance of the filter material, poor hardness, and poor wrinkle processability.
