pm2.5 protection chip

Abstract

The invention discloses a PM2.5 protection chip which comprises an outer layer and a core layer. The core layer is packaged by the outer layer to be bag-shaped, namely, the protection chip. The protection chip is rectangular. The PM2.5 protection chip has the advantages of being novel in design, standard in process, simple and convenient to use, suitable for industrialized mass production, high in adsorption rate, small in resistance, antibacterial and the like. In addition, porosity is high, specific surface area is large, air permeability is good, and the PM2.5 protection chip provides a simplest and most effective measure to avoid health hazard to human health caused by atmospheric pollution, especially haze weather, and can be widely used in the field of protection from atmospheric pollution.

Description

technical field [0001] The invention relates to a chip for protecting air pollution, in particular to a chip for PM2.5 protection. Background technique [0002] PM2.5 (Particulate Matter 2.5) refers to the general term for solid particles or liquid droplets less than or equal to 2.5 μm in the air. This kind of tiny particles can enter the lungs, so it is also called fine particles or particles entering the lungs. It is organic carbon compounds, sulfates, nitrates, ammonium salts, and elements such as sodium, magnesium, calcium, aluminum, iron, and even lead, zinc, arsenic, and cadmium. Because of their tiny particles and light weight, they can be suspended in the air for a long time, drifting and spreading over long distances, and pollute the atmosphere. In the past two years, people saw that Beijing, Shenyang, Zhengzhou, Wuhan, Chongqing, and Shanghai were often shrouded in smog, and the visibility was greatly reduced. In Beijing, the visibility was often less than 500m, a...

Problems solved by technology

In 2003, there was an estimate in the United States that if the PM2.5 detection standard was met, the United States could avoid tens of thousands of premature deaths, tens of thousands of hospital visits, and millions of people missing work. The air pollution situation at the time of the estimate was still good

However, although the existing protective masks and filter screens have certain effects, they do not work at all on tiny particles, especially fine particles with bacteria or viruses.
