Abstract

The invention provides an alloy disinfection silk and a PM (particulate matter)2.5 removing mask prepared from the alloy disinfection silk. The alloy disinfection silk is manufactured by mixing 50 to 61 percent of copper, 19 to 36 percent of zinc and 9 to 21 percent of silver, and a plurality of alloy disinfection silks are longitudinally and transversely woven into an alloy disinfection silk screen. The alloy disinfection silk provided by the invention is in contact with PMs in the atmosphere, and electrostatic environment can be instantaneously generated for adsorbing the PMs. The alloy disinfection silk screen manufactured by the alloy disinfection silks is arranged in a mask interlayer, during breathing, large PMs in the air are filtered away through filtering cloth of the mask, the PM 2.5 except large PMs in the air can be adsorbed through the alloy disinfection silk screen, the alloy disinfection silk screen adsorbs the PMs through charge and electrostatic effects, and experiments show that the adsorption effect is extremely good.

Description

The mouth mask of a kind of alloy sterilization silk and removal PM2.5 thereof
Technical field
The present invention relates to B alloy wire, is a kind of alloy sterilization silk and the mouth mask removing PM2.5 thereof.
Background technology
The alloy sterilization silk of applicant's development may be used for the dust removed impurities in water and remove in air.Remove the structure formation that dust in air mainly adopts mouth mask, mouth mask is a kind of traditional ordinary articles, can the mouth mask of filtering PM2.5 there is kind more than ten on sale in recent years, the primary structure of these mouth masks is the filter cloth numbers of plies increasing mouth mask, the deficiency of these mouth masks is: owing to mainly removing impurity by bed filtration to the dust in air, therefore, the mouth mask removing PM2.5 effect best is tens layers, but filtering layer gets over the oxygen deficiency that the next negative effect of multi-band is suction, activity slightly increases, and directly makes expiratory dyspnea, sensation people being had feel oppressed; Separately have a kind of structure of adding activated carbon in filtering layer, although can adsorb certain air plankton, the effect removing PM2.5 is after testing still not good enough.
Summary of the invention
The object of the invention is, provide the mouth mask that a kind of alloy sterilizes silk and removal PM2.5 thereof, make alloy sterilization silk screen with alloy sterilization silk, alloy sterilization silk screen, for being arranged in the interlayer of mouth mask, enables the PM2.5 in mouth mask filtering air.
The present invention for achieving the above object, be achieved through the following technical solutions: a kind of alloy sterilization silk, alloy sterilization silk is mixed by weight percentage by copper, zinc and silver, by weight percentage: copper content is 50-61%, Zn content is 19-36%, and silver content is 9-21%.Many alloy sterilization silks are adopted to be compiled into alloy sterilization silk screen in length and breadth.
A mouth mask of PM2.5 is removed in the preparation of alloy sterilization silk, comprises outer cover, arranges the first filter cloth and the second filter cloth in outer cover, fixes alloy sterilization silk screen between the first filter cloth and the second filter cloth, and the mesh of alloy sterilization silk screen is 10-150 order.Mesh in alloy sterilization silk screen is 60-90 order, and alloy sterilization silk screen is two superimposed.Mesh in alloy sterilization silk screen is 10-59 order, and alloy sterilization silk screen is three stackedly to add.The inside edge place of outer cover connects silica gel draught excluder.The mesh of alloy sterilization silk screen is 91-140 order.The B alloy wire diameter of alloy sterilization silk screen is 10-50 micron.The alloy sterilization filament diameter of alloy sterilization silk screen is 5-20 micron.Alloy sterilization silk in alloy sterilization silk screen is flat wire.
Alloy sterilization silk provided by the invention contacts with the particulate matter in air, can produce electrostatic environment instantaneously, adsorption particle thing.The alloy sterilization silk screen made with alloy sterilization silk is arranged in mouth mask interlayer, macrobead thing during breathing in air filters through mouth mask filter cloth, PM2.5 in air except macrobead thing is all by the absorption of alloy sterilization silk screen, alloy sterilization silk screen is by electric charge and electrostatic interaction adsorption particle thing, and experiment shows that its adsorption effect is fabulous.Another advantage of mouth mask of the present invention is that breathing is smooth and easy, and the filter cloth thickness of mouth mask only needs four metafiltration cloth, at least can reduce to two-layer.The present invention also has advantages such as being easy to cleaning and long service life.
Comparison Be very effective is different by experiment for the effect of the present invention adopt alloy to sterilize mouth mask filtering PM2.5 of removal PM2.5 prepared by silk and the commercially available effect removing PM2.5 mouth mask.Experiment of the present invention is divided into control group, commercially available removal PM2.5 mouth mask A, B, C tri-groups and mouth mask of the present invention three groups of D1, D2, D3.In mouth mask of the present invention, D1 is one deck alloy sterilization silk screen, and mesh is 80 orders, and D2 is one deck alloy sterilization silk screen, and mesh is 50 orders, and D3 is two laminated gold sterilization silk screen superpositions, and mesh is 20 orders.Each experimental group all gathers ambient atmosphere, flow velocity 85L/min, continuous acquisition 8 hours, adopts 0.45 μm of millipore filtration to be carrier, control group directly gathers ambient atmosphere, and the mouth mask of commercially available PM2.5 mouth mask group and mouth mask group of the present invention is installed in the ingress gathering ambient atmosphere.Gather air and terminate rear taking-up millipore filtration, examine under a microscope after process sampling membrane, 40 times of amplifications, contrast each group of photo of taking pictures are known: commercially available mouth mask group has filtering effect to the particulate matter in air, and PM10 particle obviously reduces, and PM2.5 particle is without obvious minimizing; Mouth mask group PM2.5 particle of the present invention obviously reduces.The atmospheric environment gathered in experiment is positioned at Changqing District, Jinan City, Shandong Province, and this area's motor vehicle, factory and thermal power unit are less, and PM2.5 particle is mainly inorganics, and organic combustion thing, carbide and sulfide are less.The mouth mask of removal PM2.5 of the present invention, it is applicable to multiple crowd, such as: the crowd of children, grownup and various figure.
