Method for processing microcrystalline glass panel of household induction cooker and product therefrom

Abstract

The invention discloses a method for processing a microcrystalline glass panel of a household induction cooker and a product therefrom. At present, when a metal material is sprayed on the surface of the microcrystalline glass panel of the household induction cooker, an ordinary thermal spraying manner, a cold spraying manner, a chemical manner or a silk printing manner is adopted, wherein the methods have corresponding defects. According to the invention, a metal layer or metal compound layer with the thickness of 0.01-1mm is sprayed on the surface or the local surface of the microcrystalline glass panel of the household induction cooker, wherein the specific processing steps are as follows: firstly, performing sand-blasting on the surface or the local surface of the microcrystalline glass panel; and then performing supersonic spraying on the surface of the sand-blasted microcrystalline glass panel by using metal spraying powder. The processing method disclosed by the invention cannot cause fracture of the microcrystalline glass panel because of excessive temperature rise; and the manufactured product has the characteristics of low cost, good bonding performance of coatings, and good wear resistance.

Description

technical field [0001] The invention relates to a glass-ceramic panel of a household induction cooker, in particular to a processing method for spraying metal and metal compounds on the surface of a glass-ceramic panel of a household induction cooker and the prepared glass-ceramic panel. Background technique [0002] At present, when spraying metal materials on the surface of the glass-ceramic panel of the household induction cooker, or on the surface of materials with similar properties to the glass-ceramics, either ordinary thermal spraying (plasma spraying), or cold spraying, chemical methods or silk screen methods are used. [0003] When ordinary thermal spraying (plasma spraying) is applied on the surface of glass-ceramic panels, or on the surface of materials with similar characteristics to glass-ceramics, there are the following disadvantages: [0004] 1. In the process of spraying metal materials, the substrate to be sprayed needs to be heated to thousands of degrees...

AI Technical Summary

Problems solved by technology

[0004] 1. In the process of spraying metal materials, the substrate to be sprayed needs to be heated to thousands of degrees Celsius, and if the temperature of the substrate to be sprayed is not enough, it is easy to cause insufficient bonding between the sprayed material and the substrate to be sprayed

[0005] 2. The characteristics of glass-ceramics and materials similar to those of glass-ceramics are low thermal expansion coefficients. After high-temperature treatment, if no protective measures are taken during the cooling process, they are easily damaged.

[0006] 3. Affected by the ordinary thermal spraying (plasma spraying) process itself, the surface density of the sprayed material attached to the glass-ceramics and materials with similar characteristics to the glass-ceramics is relatively low, and oxides will be produced under high temperature, which will affect the glass-ceramics and the Natural gloss on the surface of a material with similar properties to glass-ceramics

[0007] 4. During the production process of ordinary thermal spraying (plasma spraying), a large amount of dust, toxic metal vapor, thermal radiation, noise and other pollution will be generated, which will cause serious interference and potential safety hazards to construction personnel and the environment

[0010] 1. During cold spraying, the bonding force between the sprayed material and the base layer to be sprayed is not enough

[0011] 2. When using chemical method and silk screen method, the thickness of metal material (generally can only be less than 0.05mm) and density are limited

[0012] 3. When silk screen printing is used, the post-drying process is required, and the production cost is high
