Problems solved by technology

[0005] The second is to affect mental health: gray weather can easily lead to pessimism, if not adjusted in time, it is easy to lose control
[0006] The third is to affect traffic safety: when hazy weather occurs, outdoor visibility is low, pollution continues, traffic jams, and accidents occur frequently
However, the fundamental control of air pollution requires the joint efforts of the government, enterprises and even the whole world, which is a very complicated and lengthy process
However, the electrical products such as air purifiers that have been developed so far are not only expensive, bulky, and occupy a lot of space, but also need to consume electricity, which is not low-carbon and environmentally friendly.

Embodiment 1

[0023] First, nano-silver particles (particle size is 10-20nm), dispersant (polyvinylpyrrolidone, model K30) and binder (hansi, PDA) are uniformly dispersed in water to obtain a nano-silver solution; wherein, the nano-silver particles The concentration is 400ppm, the concentration of the dispersant is 300ppm, and the concentration of the binder is 0.5wt%. The window screen net woven by the bamboo charcoal fiber yarn is dipped in the nano-silver solution, taken out after 8-10 hours, and dried to obtain the window screen net.

[0024] The window screen net is made into a screen window and installed on windows of buildings with more than 10 floors. After the windows are opened continuously for 10 hours, the indoor air quality is tested according to the "Indoor Air Quality Standard" GB / T18883-2002. Compared with the indoor air test results of installing ordinary screen windows: in the air, the content of sulfur dioxide and nitrogen dioxide is reduced by 75%; the inhalable particl...

Embodiment 2

[0026] First, nano-silver particles (particle size is 10-20nm), dispersant (polyvinylpyrrolidone, model K30) and binder (hansi, PDA) are uniformly dispersed in water to obtain a nano-silver solution; wherein, the nano-silver particles The concentration is 500 ppm, the concentration of the dispersant is 200 ppm, and the concentration of the binder is 0.1 wt%. The window screen net woven by the bamboo charcoal fiber yarn is dipped in the nano-silver solution, taken out after 8-10 hours, and dried to obtain the window screen net.

[0027] The window screen net is made into a screen window and installed on windows of buildings with more than 20 floors.

Abstract

The invention provides a screen window mesh for purifying indoor air, and the screen window mesh is formed by weaving bamboo charcoal fiber yarns, wherein nanometer silver is evenly distributed on the surface of the screen window mesh. The screen window mesh for purifying indoor air is characterized in that the indoor air quality at the high altitude in the haze weather can be effectively controlled and improved, and harmful bacteria, microorganisms and dust in the air can be furthest adsorbed. The screen window mesh has a great effect on the body health of indoor habitants. For future city construction, the screen window mesh has a great meaning for the body health of all urban residents, and has a critical effect on improving the future urban living environment.

Description

technical field [0001] The invention relates to a window screen, in particular to a window screen which can purify indoor air. Background technique [0002] In recent years, with the development of industrialization, air pollution has become more and more serious, which has affected people's daily life and health. The survey results show that there are 100 to 200 days in a year in some big cities in my country where there are haze days. The so-called haze weather refers to the large amount of nitrogen oxides and particulate matter in the air, resulting in low visibility. During haze weather, the main components in the air are dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles. These substances can make the atmosphere turbid, blur the vision and cause visibility to deteriorate. The visual range obstruction caused by the aerosol system composed of fine particles is called haze. The reason for the haze weather is that the urban diffusion conditions ar...
