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.
The traditional single filter paper can no longer meet people's requirements for a high-quality air environment, so a composite high-efficiency air filter with high filtration efficiency and large dust holding capacity is required

Embodiment

[0018] A kind of preparation method of thalassemia enhanced air filter paper, comprises the following steps:

[0019] Step 1: Grind and beat the quinces, then add protease and glucoamylase, keep the temperature at 28-35°C, let it stand for 60-72 hours, then carry out centrifugation at a speed of 3500r / min, take the lower layer of sediment and dry it , grind to more than 200 meshes, add water to make a solution with a concentration of 2%, add a dispersant, stir evenly, and make a celandine additive;

[0020] Step 2, taking chopped glass fibers with an average diameter of 6-10 μm, adding them into a salt solution with a pH value of 6-8 for beating, adding a dispersant, and then performing deflagging on a deflagging machine, the number of flaking rotations is 10,000-15,000 revolutions;

[0021] Step 3: Add polyamide polyamine epichlorohydrin resin solution to the decomposed chopped glass fiber solution, and then shape it on a wet molding machine to make chopped glass fiber hand-s...

Abstract

The invention discloses a preparation method of Lythrum salicaria enhanced air filter paper. A piece of novel air filter paper is prepared by using chopped glass fibers and glass cotton fibers with different fiber diameters, furthermore, Lythrum salicaria is added in the novel air filter paper to further improve the filtering effect. The preparation method disclosed by the invention is simple and reasonable in process, high in yield and low in production cost, and the chopped glass fibers and the glass cotton fibers with different fiber diameters are prepared into the double-layer composite air filter paper, thereby improving the filtration efficiency, further lowering the wind resistance and enhancing the dust capacity; besides, a Lythrum salicaria additive is added, so that the filtering effect for harmful gases such as formaldehyde and the like can be further improved on the one hand, and the dust capacity of the Lythrum salicaria enhanced air filter paper can be further enhanced.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a method for preparing chitidron-enhanced air filter paper. Background technique [0002] As the main component of high efficiency filter, air filter paper determines the filtration efficiency of high efficiency filter. 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. The traditional single filter paper can no longer meet people's requirements for a high-quality air environment, so a composite high-efficiency air filter with high filtration efficiency and large dust holding capacity is required. [0003] As a common aquatic plant, it has not only been useless, but also endangers the balance of the aquatic environment if it reproduces excessively. Con...
