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 hydrilla verticillium enhanced air filter paper, comprising the following steps:

[0019] Step 1, take the Hydrilla verticillum, grind and beat it, 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 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 Hydrilla verticillium 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 cho...

Abstract

The invention discloses a preparation method of hydrilla verticillata reinforced air filter paper. Novel air filter paper is made by using short glass fibers and glass wool fibers which are different in diameter, meanwhile hydrilla verticillate is added, and a filtering effect is further improved. The preparation method is simple and reasonable in process, high in finished product rate and low in production cost, the short glass fibers and glass wool fibers which are different in diameter are used for making the double-layer composite air filter paper, the filtering efficiency is improved, meanwhile air resistance is reduced, and clogging capacity is improved. In addition, the additive hydrilla verticillata is added, the effect of filtering harmful gases such as formaldehyde can be further improved, and the clogging capacity of the hydrilla verticillata reinforced air filter paper is further improved.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a method for preparing air filter paper enhanced by Hydrilla verticillium. 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, Hydrilla verticillium has not only been unused, but also endangered the balance of the aquatic environment d...
