Method for processing microcrystal glass panel and produced product

Abstract

The invention discloses a method for processing a microcrystal glass panel and a produced product. At present, a common thermal spraying, cold spraying, chemical or silk-printing way having corresponding disadvantages is usually adopted for spraying a metal material on the surface of the microcrystal glass panel. According to the invention, a metal layer or a metal compound layer of 0.01-1 mm in thickness is sprayed on the surface or partial surface of the microcrystal glass panel; and the specific processing method comprises the following steps of: firstly, performing sand blasting on the surface or partial surface of the microcrystal glass panel; and then supersonically spraying metal spraying particles on the surface of the microcrystal glass panel after the sand blasting. The method for processing the microcrystal glass panel, disclosed by the invention, prevents from causing breakage of the microcrystal glass panel due to over-high temperature rise; and the produced product has the characteristics of low cost, good bonding properties and good abrasion resistance.

Description

technical field [0001] The invention relates to the field of glass-ceramic panels, in particular to a processing method for spraying metal and metal compounds on the surface of a glass-ceramic panel and a glass-ceramic panel prepared therefrom. Background technique [0002] At present, when spraying metal materials on the surface of glass-ceramic panels or on the surface of materials with similar characteristics to 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 Celsius, and if the temperature of the substrate to be sprayed is not enough, it...

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
