Problems solved by technology

Ordinary dust-proof screens either increase the mesh number of the screen from the physical structure of the screen, or paste a layer of adsorbent material to improve the filtration efficiency of particulate matter, but the filtration efficiency of fine particles is not good. , cannot effectively solve indoor PM in outdoor haze weather 2.5 concentration problem

Abstract

The invention relates to a PM2.5 protection composite screen window mesh. The composite screen window mesh comprises a screen layer, an adsorption layer is arranged on one side of the screen layer, one face of the absorption layer is tightly attached to the screen layer, and viscose strips are arranged on the periphery of the other face of the adsorption layer. The adsorption layer at least comprises a polypropylene fiber spunbonded non-woven fabric layer and an ultra-fine denier electret melt-blown fiber non-woven fabric layer. Small vent holes are evenly distributed in the polypropylene fiber spunbonded non-woven fabric layer, and the weight per unit area of the ultra-fine denier electret melt-blown fiber non-woven fabric layer ranges from 25 grams per square meter to 50 grams per square meter. The PM2.5 protection composite screen window mesh can efficiently filter and adsorb PM2.5 particulate matter in air, the indoor air environment can be purified, the indoor PM2.5 concentration is effectively reduced, the PM2.5 filter efficiency reaches 99%, high breathability, light transmission and PM2.5 filter efficiency can be achieved, and high PM2.5 filter efficiency of the screen window mesh, breathability and light transmission of the screen window mesh, and normal air ventilation and daylighting can be guaranteed.

Description

technical field [0001] The invention relates to a composite window screen, in particular to a filter capable of filtering PM 2.5 Composite window screens. Background technique [0002] high concentration of PM 2.5 Pollution affects ambient air quality and physical health. PM 2.5 Refers to particulate matter with a diameter less than or equal to 2.5 μm in the atmosphere, also known as particulate matter that can enter the lungs. Each person inhales an average of about 10,000 liters of air every day. The fine dust that enters the alveoli can be quickly absorbed, and directly enter the blood circulation and distribute to the whole body without detoxification by the liver; secondly, it will damage the ability of hemoglobin to transport oxygen and lose blood. For patients with anemia and circulatory disorders, serious consequences may occur. For example, it can aggravate respiratory diseases and even cause heart diseases such as congestive heart failure and coronary arteries...
