Example Embodiment

[0046] Example 1:

[0047] The first step is to dissolve 95.0% pure platinum in aqua regia to obtain chloroplatinic acid (H2PtCl6·6H2O, red to brown-red solid), dissolve solid chloroplatinic acid in water, and then add 2.0% number average to the net chloroplatinic acid aqueous solution Polyvinyl alcohol with a molecular weight of 5000, stir for 10 minutes and then stand by; the second step is to soak the glass fiber mesh with a thickness of 1.0mm in the water in the stainless steel reactor, and then make the water temperature and pressure exceed the critical point (critical temperature T = 374 ℃, critical pressure P=22.1MPa) is supercritical water. Supercritical water has very good oxidizing properties. It can oxidize / etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (this makes the first The solution is easier to "bond" on the surface of the glass fiber mesh); in the third step, the treated glass fiber mesh is soaked in the solution o...

[0049] Example 2:

[0050] The first step of the present invention is to dissolve platinum with a purity of 96.0% in aqua regia to obtain chloroplatinic acid (H2PtCl6·6H2O, red to brown-red solid), dissolve solid chloroplatinic acid in water, and then add 3.0 to the chloroplatinic acid aqueous solution. % Polyvinyl alcohol with a number average molecular weight of 5000, stir for 15 minutes and then stand by; the second step is to soak the 2.0-thick glass fiber mesh in the water in the stainless steel reactor, and then make the water temperature and pressure exceed the critical point (critical temperature T =374℃, critical pressure P=22.1MPa), supercritical water will become supercritical water. Supercritical water has very good oxidizing properties and can oxidize / etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (which makes The solution in the first step is easier to "bond" on the surface of the glass fiber mesh); in the third step, ...

[0052] Example 3:

[0053] The first step of the present invention is to dissolve platinum with a purity of 97.0% in aqua regia to obtain chloroplatinic acid (H2PtCl6·6H2O, red to brown-red solid), dissolve solid chloroplatinic acid in water, and then add 4.0 to the chloroplatinic acid aqueous solution. % Polyvinyl alcohol with a number average molecular weight of 5000, stir for 20 minutes and then stand by; the second step is to soak the 3.0mm glass fiber mesh in the water in the stainless steel reactor, and then make the water temperature and pressure exceed the critical point (critical temperature After T=374℃, critical pressure P=22.1MPa), supercritical water will become supercritical water. Supercritical water has very good oxidizing properties and can oxidize / etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (this Make it easier for the solution in the first step to "bond" on the surface of the glass fiber mesh); in the third ste...

Abstract

The invention provides a nanometer platinum net material, a preparing method of the nanometer platinum net material and an air purifier. The nanometer platinum net material comprises a net body and nanometer platinum particles which are attached to the net body and form a nanometer platinum particle layer on the outer side of the net body. According to the technical scheme, the nanometer platinum particle layer is formed on the outer side of the nanometer platinum net material, and nanometer platinum has the effect of absorbing energy of ultraviolet light; when ultraviolet light irradiates nanometer platinum, the wavelength can be increased, and meanwhile a certain amount of heat can be generated, in other words, ultraviolet light can be changed into visible light harmless to the human body. The nanometer platinum net material can change ultraviolet light into visible light in the same way, and thus the effect of isolating or shielding ultraviolet light can be achieved; when the nanometer platinum net material is applied to the air purifier, the effect of isolating disinfecting ultraviolet lamps in the air purifier can be achieved, leaking of ultraviolet light can be avoided, and thus human health can be protected.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to a nano-platinum mesh material, a manufacturing method thereof, and an air purifier. Background technique [0002] With the seriousness of air pollution and people's pursuit of quality of life, the quality of air quality has been paid more and more attention. On average, people spend most of their time indoors. Indoors have become an important place for people to work, rest and entertain. Therefore, it can be said that indoor air quality directly affects people's quality of life and even health. Therefore, "indoor air pollution" is becoming a topic of increasing concern. People spend more than 4 times the time they spend indoors every day. Most of the air they breathe every day is indoor air. Therefore, indoor air quality has a greater impact on health. Indoor air pollution is often more serious than outdoor air pollution. In some cases, the severity of the former can reach more than one hun...
