Problems solved by technology

However, the usual home life is also indispensable for ventilation requirements. The usual solution is to ventilate through ventilation facilities with air purification functions, or use indoor air purification equipment to purify the air entering the room. For the former Ventilation efficiency is limited, and for the latter, air purification efficiency is limited, so none of the above solutions can solve the problem of introducing air pollutants into the room during ventilation in modern urban life.

Abstract

The invention discloses a window screening capable of releasing anion and filtering particle matter (PM) 2.5 particles. The window screening comprises a grid cloth with the aperture of 1-3mm and a microfiltration membrane, wherein the grid cloth provides a framework supporting function and is made from any one of polyester, polypropylene, acrylic fibers 6, acrylic fibers, high strength glass fiber, and inflaming retarding aramid fiber, the microfiltration membrane is used for air ventilation and filtration and made of a Teflon material, the aperture of the microfiltration membrane is 0.2-5.0mm, the thickness of the microfiltration membrane is 0.01-0.05mm, the grid cloth and the microfiltration membrane are laminated, the grid cloth faces towards the indoor, and the microfiltration membrane faces the outdoor. The window screening capable of releasing anion and filtering PM 2.5 particles has functions of existing window screenings and is capable of filtering fine particle pollutants in the air and meeting actual use requirements.

Description

technical field [0001] The invention relates to a window screen for filtering air fine particle pollutants, in particular to a window screen capable of releasing negative ions and filtering PM2.5 particles, and belongs to the technical field of environmental protection and healthy household products. Background technique [0002] With the continuous improvement of productivity and consumption levels, problems such as industrial pollution and vehicle exhaust emissions are becoming more and more serious, and people's pursuit of environmental protection and health is becoming more and more urgent. As we all know, PM2.5 is one of the main factors of air pollution, which is very harmful to human health. Because of its small diameter, it can enter the deep part of the respiratory tract, and most of it is deposited in the upper respiratory tract. The finer particle pollutants It even goes deep into the bronchioles and alveoli, directly affecting the ventilation function of the lung...
