Embodiment 1

[0021] Embodiment 1, take the purification composite material of the present invention of producing 110 kilograms as example:

[0022] The HEPA purification composite material of the present invention improves the problem of low efficiency and high resistance of purification composite materials in domestic traditional enterprises, and at the same time greatly reduces the product cost. For many filter manufacturers in the market, it has solved the technical and cost problems.

[0023] The specific scheme of the "HEPA purification composite material" developed by the present invention is to change the traditional HEPA purification composite material process and bonding method. In the production process, the traditional enterprise uses a single-layer high-gram weight 50-gram melt-blown material and a 70-gram substrate composite method. Change to a double-layer low-gram weight 20-gram melt-blown material and a 70-gram base material hot-melt adhesive for bonding. First, use 70 hig...

According to the present invention, the purification composite material has advantages of low resistance, high filtration efficiency, enhanced electrostatic adsorption capacity, large dust collection capacity, and the like; and the method has advantages of simple production process, low production equipment investment, low production cost, green and environmentally friendly production process, and the like.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a purification composite material. Background technique [0002] In the air filtration industry, a large number of HEPA (High efficiency particulate air Filter) purification composite consumables are needed to be used in the composite materials of filter bags, filter elements, and purifiers. At present, most of the substrates produced by polyester long fiber technology appear on the market. The base material of this long-fiber process is limited by the long-fiber process, uneven cloth surface, low air permeability, high cost and other factors, resulting in a series of problems such as unsatisfactory performance of air filter products. [0003] Therefore, there is an urgent need in the market for a purification composite material that meets the product characteristics of the air purification industry and has the characteristics of high air permeability, low resistance, a...
