Problems solved by technology

However, metal dust-collecting plates face severe challenges of multiple corrosion factors such as water vapor, micro-current, ozone, and dust in a high-voltage electric field environment. Long-term use is prone to electrochemical corrosion and other problems, which will accelerate the destruction of the oxide layer on the surface of the aluminum plate.
[0003] Moreover, with the deposition and diffusion of dust particles on the damaged surface of the material, the dirt on the surface of the aluminum plate is difficult to clean, which seriously affects the user experience

Embodiment 1

[0034] A Zr-based amorphous coating comprises the following raw materials in atomic mole percentages: Zr 66%, Cu 17.5%, Al 10.5%, Fe 6%.

[0035] The preparation process of the Zr-based amorphous coating is as follows:

[0036] Four elements of Zr (99.99%), Cu (99.99%), Al (99.99%), and Fe (99.99%) are selected, and the ratio is Zr66%, Cu17.5%, Al10.5%, and Fe6%. Amorphous powder, the particle size of the amorphous powder is 11-16 μm, and the amorphous component has strong glass forming ability, which is convenient for the preparation of the amorphous coating.

[0037] Using an aluminum plate with a size of 90mm×37mm×0.8mm as the substrate, first use alcohol to clean the stains and rust spots on the surface of the substrate to remove organic matter adhered to the surface and prevent residual pollutants from affecting the combination of the coating and the substrate material. Then, use shot peening technology to roughen the surface of the substrate, so that the surface roughne...

Embodiment 2

[0042] A kind of application of Zr-based amorphous coating in electric purification, using the Zr-based amorphous coating prepared in Example 1 to carry out electric purification environmental test, the details are as follows:

[0043] The present invention adopts the Zr-based amorphous coating in Example 1 to take a TEM image in an electric purification environment. The temperature of the electric purification environment is 25℃±2, the humidity is about 50%±10, the ozone content of the whole machine is controlled within 500ppb, and the microcurrent varies in the range of mA level, and it is about 0.1mA when it is stable. 3 Cigarette particles were selected for CADR testing in the purification experimental chamber, and the particle size range was 0.09-1 μm. The obtained TEM image is as follows Figure 4 shown. through the Figure 4 It can be seen from the TEM image in Figure 4 The inset is a selected-area diffraction pattern, which consists of concentric rings with differ...

Description

technical field [0001] The invention relates to the field of amorphous coatings, in particular to a Zr-based amorphous coating, its preparation process and its application in electrical purification. Background technique [0002] Electric purification products have many advantages such as small resistance, low pressure drop, long service life, ideal virus elimination, etc., and occupy a place in air purification. However, metal dust-collecting plates face severe challenges of multiple corrosion factors such as water vapor, micro-current, ozone, and dust in a high-voltage electric field environment. Long-term use is prone to electrochemical corrosion and other problems, which accelerates the destruction of the oxide layer on the surface of the aluminum plate. [0003] Moreover, with the deposition and diffusion of dust particles on the damaged surface of the material, it is difficult to clean the dirt on the surface of the aluminum plate, which seriously affects the user expe...
