Problems solved by technology

The smaller the fiber diameter of the air filter paper, the smaller the particle size for removing particles in the air, and the higher the filtration efficiency, but the greater the relative wind resistance, the slower the filtration speed, and the lower the dust holding capacity. Traditional single filter paper The filter effect is not good, it is easy to grow bacteria and mold, the mechanical strength and durability of the filter paper are not good, and it can no longer meet people's requirements for a high-quality air environment. Therefore, a composite and efficient air with high filtration efficiency and large dust holding capacity is required. filter

Embodiment 1

[0031] A method for manufacturing anti-deformation high-efficiency filter paper, comprising the following steps:

[0032] Step 1. Send waste paper to a pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain a waste paper pulp stock solution. Add 6% of the stock solution to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0033] Step 2, put the wood pulp fiber and the straw pulp fiber into the mixer according to the weight ratio of 3:1, stir and beating for 7 minutes, so that the plant fiber is evenly dispersed in the water, wherein the wood pulp fiber is made of coniferous wood pulp fiber and broadleaf wood pulp fiber according to the weight The ratio is 1:4, and then the pulped plant fiber and the mixed slurry prepared in step 1 are evenly mixed and injected into the material tan...

Embodiment 2

[0048] A method for manufacturing anti-deformation high-efficiency filter paper, comprising the following steps:

[0049] Step 1. Send waste paper to a pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain a waste paper pulp stock solution. Add 8% of the stock solution to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0050] Step 2, put the wood pulp fiber and the straw pulp fiber into the mixer according to the weight ratio of 3:1, stir and beat for 9 minutes, so that the plant fiber is evenly dispersed in the water, wherein the wood pulp fiber is made of coniferous wood pulp fiber and broadleaf wood pulp fiber according to the weight The ratio is 1:4, and then the pulped plant fiber and the mixed slurry prepared in step 1 are evenly mixed and injected into the material tank t...

Embodiment 3

[0065] A method for manufacturing anti-deformation high-efficiency filter paper, comprising the following steps:

[0066] Step 1. Send waste paper to a pulper for disintegration, and then beat and deink the waste paper. The pulp after beating and deinking flows into the pulp tank to obtain a waste paper pulp stock solution. Add 7% of the stock solution to the waste paper pulp stock solution. viscose fiber, and stir with a stirring rod to prevent the fiber from settling, and obtain a mixed slurry for subsequent use;

[0067] Step 2, put the wood pulp fiber and straw pulp fiber into the mixer according to the weight ratio of 3:1, stir and beat for 8 minutes, so that the plant fiber is evenly dispersed in the water, wherein the wood pulp fiber is made of coniferous wood pulp fiber and broadleaf wood pulp fiber according to weight The ratio is 1:4, and then the pulped plant fiber and the mixed slurry prepared in step 1 are evenly mixed and injected into the material tank to obtain...

Abstract

The invention discloses a method for manufacturing an anti-deformation high-efficiency filter paper. The method comprises the steps of step one, preparation of mixed slurry; step two, preparation of mixed fiber slurry; step three, preparation of mixed powder; step four, preliminary preparation of a paper base; step fifth, the preparation of a mixed paste; step six, the preparation of a reaction mixture; step seven, coating and drying of the paper base to obtain the final anti-deformation high-efficiency filter paper. The filter paper has good air permeability, low airflow resistance and excellent filtering efficiency, has the functions of having plant floral, being mildewproof and bactericidal and effectively repelling mosquitoes, and has excellent anti-deformation performance, pressure difference resistance performance and bursting strength performance, and the method uses a large amount of waste, reduces costs, protects the environment, saves resources, and has high practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for manufacturing anti-deformation high-efficiency filter paper. Background technique [0002] The air conditioner filter element is the most commonly used component in every vehicle. It filters the air outside the car and sends it into the car, which improves the air quality in the car. The air filter paper, as the main component of the air conditioner filter element, determines the high efficiency filter. filtration efficiency. The smaller the fiber diameter of the air filter paper, the smaller the particle size for removing particles in the air, and the higher the filtration efficiency, but the greater the relative wind resistance, the slower the filtration speed, and the lower the dust holding capacity. Traditional single filter paper The filter effect is not good, it is easy to grow bacteria and mold, the mechanical strength and durability of the filter pa...
