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 chrysanthemum enhanced air filter paper, comprises the following steps:

[0019] Step 1: Take the sage grass and grind it into a pulp, then add protease and glucoamylase, keep the temperature at 28-35°C, let it stand for 60-72 hours, then perform centrifugation at a speed of 3500r / min, take the lower layer of sediment and dry it, Grind to more than 200 mesh, add water to make a solution with a concentration of 2%, add a dispersant, stir evenly, and make a weed grass 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 gl...

Abstract

The invention discloses a method for preparing potamogeton-crispus-enhanced air filter paper. Novel air filter paper is prepared from chopped glass fibers and glass cotton fibers which are different in fiber diameter; meanwhile, potamogeton crispus is added, and the filtering effect is further improved. According to the method, the technology is simple and reasonable, the finished product rate is high, and the production cost is low; the double-layer composite air filter paper is prepared from the chopped glass fibers and the glass cotton fibers which are different in fiber diameter, and the filtering efficiency is improved; meanwhile, the wind resistance is reduced, and the dust capacity is increased; meanwhile, as the potamogeton crispusa additive is added, the filtering effect on harmful gas such as formaldehyde can be further improved, and the dust capacity of the potamogeton-crispus-enhanced air filter paper is further increased.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a method for preparing a smilax-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, weed has not only been unused, but also endangered the balance of the aquatic environment due to excessive reproduction. C...
