Aromatherapy spray film, humidification spray film, medical film atomization and atomization control panel, the new health ..

Microporous film atomization spray film belongs to a series of rare earth ceramic rings baking at high temperatures for a long time stuck in etched stainless steel top, mainly used for small atomizing device, is as 3.7V cosmetic sprayer, USB humidifier, Car humidifier, this kind of toy cars. Although a variety of spray films, but the principle is basically the same, are the high number of vibration through the resonant frequency of the liquid instantly atomization, atomized particles can reach micron level, even if the device is not on the computer table It will wet surface. Microporous atomization pieces of steel material etched stainless steel and stainless steel stamping, etching material normally used for 20mm, press material for the 16mm, diameter 20mm, 16mm, 13.8mm three resonant frequency of 110 ± 5KHz, 128KHz, 142KHz, 160KHz, the driving voltage 3.7V-6V, optimum 5V, there is an advantage that the product, spray mist can be directly sprayed into the air, the mist blowing fan does not need to go out, for a plant do humidifier, which not only saves cost , but also save time. Microporous film atomization origin of the name is because there are a lot of stainless steel sheet micron pores, pore diameter size of the eye is unable to identify clear, only under a microscope to see that this is the origin of the name of the microporous film atomization, components of the atomized metal sheet by SUS304 steel, piezoelectric ceramics, AB glue three materials synthesis. 304 stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. Also relatively good high temperature, the general temperature limit is less than 650 ℃. 304 stainless steel with excellent corrosion resistance between energy and good resistance to intergranular corrosion. On the oxidizing acid, obtained in the experiment: ≤65% nitric acid concentration below the boiling temperature of 304 stainless steel with strong corrosion resistance. Most of the alkali solution and organic acids and inorganic acids also have good corrosion resistance, 304 of the most important elements Ni, Cr, but it is not limited to these two elements. Specific requirements set by the product standard. Industry conditions as long as the common determination Ni content is more than 8%, Cr content is more than 18%, it can be considered 304 stainless steel. Porous spray films mainly used in small atomizer device, spray volume is very small, tens of milliliters an hour fog, the atomized particles can be done out between 4 micron to 15 microns, by a specific pore size Guests to be, the atomized liquid is a luxurious, not all can be atomized liquid, such as oily liquids can not spray, because oil is too viscous, less vibration microporous atomization pieces atomized.
