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 preparation method of hornwort enhanced air filter paper, comprising the following steps:

[0019] Step 1: Grind and beat hornwort algae, then add protease and glucoamylase, keep the temperature at 28-35°C, let stand for 60-72 hours, then perform centrifugation at a speed of 3500r / min, remove the lower 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 hornwort 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-sheets, put it in a drye...

Abstract

The invention discloses a preparation method of ceratophyllum demersum enhanced air filter paper. The novel air filter paper is prepared from shot-cut glass fibers and glass wool fibers which have different fiber diameters, ceratophyllum demersum is added, and the filtering effect is further improved. The process is simple and reasonable, the yield is high, the production cost is low, and the double-layer composite air filter paper is prepared from the shot-cut glass fibers and the glass wool fibers which have different fiber diameters, and the filtering efficiency is improved; besides, the wind resistance is reduced, and the dust holding capacity is improved; meanwhile, a ceratophyllum demersum additive is added, on one hand, the filtration effect on formaldehyde and other harmful gasses can be further improved, and the dust holding capacity of the air filter paper is further improved.

Description

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