Description

An alloy sterilizing wire and a mask thereof for removing PM2.5.

The invention relates to an alloy wire, which is an alloy sterilizing wire and a mask for removing PM2.5. BACKGROUND OF THE INVENTION Alloy sterilizing wires developed by the Applicant can be used to remove impurities from water and remove dust from the air. The removal of dust in the air mainly adopts the structure of the mask. The mask is a traditional common item. In recent years, there have been more than ten kinds of masks capable of filtering PM2.5. The main structure of these masks is to increase the filter cloth of the mask. The number of layers, the shortage of these masks is: Since the dust in the air mainly removes impurities through multi-layer filtration, the mask with the best effect of removing PM2.5 is more than ten layers, but the more the filter layer brings the negative effect Insufficient oxygen inhalation, a slight increase in activity directly makes breathing difficult, making people feel depressed; another structure that adds activated carbon in the filter layer, although it can adsorb certain air impurities, but removes PM2. The effect is still not good. Summary of the invention

The object of the present invention is to provide an alloy sterilizing wire and a mask for removing PM2.5. The alloy sterilizing wire is made into an alloy sterilizing wire mesh, and the alloy sterilizing wire mesh is installed in the interlayer of the mask to enable the mask to be filtered. PM2. 5 in the air. In order to achieve the above object, the present invention is achieved by the following technical solutions: An alloy disinfecting wire, which is prepared by mixing copper, zinc and silver in weight percentage, by weight percentage: copper content is 50-61%, zinc The content is 19-36%, and the silver content is 9-21%. The alloy disinfection wire mesh is prepared by using a plurality of alloy disinfecting wires. A mask for removing PM2.5 is prepared by using an alloy sterilizing wire, comprising a cover, a first filter cloth and a second filter cloth are disposed in the outer cover, and an alloy sterilizing wire is fixed between the first filter cloth and the second filter cloth, and the alloy sterilizing wire is The mesh of the net is 10-150 mesh. The mesh in the alloy sterilizing screen is 60-90 mesh, and the alloy sterilizing screen is superposed on two layers.

The alloy disinfecting wire provided by the invention is in contact with particles in the atmosphere, and can generate an electrostatic environment in an instant to adsorb particulate matter. The alloy sterilizing wire made of alloy sterilizing wire is installed in the mask interlayer, and the large particles in the air are filtered by the mask filter cloth when breathing, and the PM2. 5 except the large particles in the air can be adsorbed by the alloy sterilizing wire mesh. The alloy disinfection wire mesh adsorbs particles by electric charge and electrostatic action, and the experiment shows that the adsorption effect is excellent. Another advantage of the mask of the present invention is that the breathing is smooth, and the thickness of the filter cloth of the mask requires only four layers of filter cloth, and can be reduced to at least two layers. The invention also has the advantages of easy cleaning and long service life.

The invention adopts the alloy sterilizing wire to remove the PM2. 5 mask to filter out the PM2. 5 effect and the commercially available removal of the PM2. The effect of the mask is significantly different through the experimental comparison effect. The experiment of the present invention is divided into a control group, a commercially available removal PM2. 5 masks A, B, C three groups and three masks Dl, D2, D3 of the present invention. In the mask of the present invention, D1 is a layer of alloy sterilizing wire mesh with a mesh opening of 80 mesh, D2 is a layer of alloy sterilizing wire mesh, the mesh is 50 mesh, D3 is a two-layer alloy sterilizing wire mesh superimposed, and the mesh is 20 mesh. The ambient atmosphere was collected in each experimental group, the flow rate was 85 L/min, and the continuous collection was carried out for 8 hours. The 0. 45 μ πι microporous membrane was used as the carrier, and the control group was directly collected from the ambient atmosphere. The commercially available ΡΜ2.5 mask group and the mask group of the present invention were used. The masks are installed at the entrance to the ambient atmosphere. After the collection of the atmosphere, the microporous membrane was taken out, and the sampled membrane was treated and observed under a microscope. 40 times magnification and photographing were compared with each group of photographs. The commercially available mask group had a filtering effect on the particulate matter in the atmosphere, and the PM10 particles were significantly reduced. The granules of the present invention are not significantly reduced; The atmospheric environment collected in the experiment is located in Changqing District, Jinan City, Shandong Province. There are fewer motor vehicles, factories and thermoelectric equipment in the area. The ΡΜ2.5 particles are mainly inorganic substances, and there are fewer organic combustion materials, carbides and sulfides. The mask for removing ΡΜ2.5 according to the present invention is applicable to a variety of people, for example, children, adults, and people of various postures.
