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
The present invention relates to the Household induction cooker glass-ceramic panel, specifically a kind of on Household induction cooker glass-ceramic panel surface metallize and the working method of metallic compound and the glass-ceramic panel that makes thereof.
Background technology
At present, on Household induction cooker glass-ceramic panel surface, or with the material surface of devitrified glass characteristic close on during the metallize material, or adopt ordinary hot spraying (plasma spraying), or adopt cold spraying, chemical mode or silk-screen mode.
Ordinary hot spray (plasma spraying) is applied on the glass-ceramic panel surface, or with the material surface of devitrified glass characteristic close on the time, have following shortcoming:
1. in the materials process of metallize, sprayed substrate need to heat thousands of degrees centigrade, and the added temperature of substrate that is sprayed when quilt is inadequate, causes easily that also spray material is with inadequate by spraying basic unit bonding force.
Devitrified glass and with the characteristic of the material of devitrified glass characteristic close itself be that thermal expansivity is low, after the pyroprocessing, do not take sfgd. in process of cooling, easily damaged.
3. be subjected to the impact of ordinary hot spraying (plasma spraying) technique itself, spray material is attached to devitrified glass and lower with the material surface density ratio of devitrified glass characteristic close, and be subjected to high temperature can produce oxide compound, affect devitrified glass and with the surperficial original gloss of the material of devitrified glass characteristic close.
4. in ordinary hot spraying (plasma spraying) production process, the pollutions such as a large amount of dust, noxious metals steam and thermal radiation, noise be will produce, and can severe jamming and potential safety hazard be brought to workmen and environment.
Therefore, although the ordinary hot spraying method also can spray certain thickness coating, it can't be at devitrified glass, or with the material surface of devitrified glass characteristic close on implement well.
Cold spraying, chemical mode or silk-screen mode are applied on the devitrified glass surface, or with the material surface of devitrified glass characteristic close on the time, have following shortcoming:
1. during cold spraying, spray material is with inadequate by spraying basic unit bonding force.
2. when adopting chemical mode and silk-screen mode, metallic substance thickness (can only accomplish that generally 0.05mm is following) and density are restricted.
3. when adopting the silk-screen mode, also need the later stage drying course, production cost is high.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, provide a kind of the Household induction cooker glass-ceramic panel and with the material of devitrified glass characteristic close on the working method of metallize or metallic compound.
For this reason, the present invention adopts following technical scheme: a kind of working method of Household induction cooker glass-ceramic panel, its surface or local surfaces at glass-ceramic panel is sprayed with metal level or the metal compound layer that a thickness is 0.01～1mm, and concrete procedure of processing is as follows: at first surface or the local surfaces of glass-ceramic panel are carried out sandblast; Then, carry out supersonic spray coating on the glass-ceramic panel surface through sandblasting with the metal spraying powder again, processing requirement wherein is as follows: metal spraying powder temperature is 600～1800 ℃, metal spraying powder movement velocity is 500～1000m/s, metal spraying powder electric conductivity is 15～2000 ρ/n Ω m, and the powder feeding rate is 40～100g/min.
The present invention carries out the metallic substance spray treatment when the glass-ceramic panel surface, because the metal spraying powder is little, speed is fast, and in the spraying process, the glass-ceramic panel surface temperature rise is lower than 100 ℃, can not cause glass-ceramic panel to break owing to temperature rise is too high; The metal level that obtains by the working method of the present invention or mill durability performance of metal compound layer is good, density and hardness is high, the excellent bonding performance of metal level or metal compound layer and glass-ceramic panel does not need the later stage drying course, and tooling cost is low.
Further, metal or other similar metallic compounds such as the preferred silver of the material of described metal spraying powder, copper, aluminium, zinc, cobalt, cadmium, nickel, iron, platinum, lead, antimony, titanium or manganese.
Further, the smart rugosity Ra of glass-ceramic panel after sandblast be greater than 2 μ m, makes the bonding properties of itself and metal level or metal compound layer better.
Further, described glass-ceramic panel adopts with the black crystal panel of devitrified glass characteristic close, white crystal panel, ceramic panel or toughened glass panel and replaces.
Another technical scheme of the present invention provides a kind of Household induction cooker glass-ceramic panel that adopts above-mentioned working method to obtain, and it is characterized in that the surface of glass-ceramic panel or local surfaces are sprayed with metal level or the metal compound layer that a thickness is 0.01～1mm.
Further, described surface comprises upper surface, lower surface and two sides.
Further, described metal level or metal compound layer are narrow strip, bulk or spot distribution.
Further, metal level or metal compound layer on the junction between the two ends of glass-ceramic panel upper surface, two sides, lower surface and each face are continuous distribution, convenient processing.
The present invention has the following advantages by adjusting spraying coating process and corresponding spraying parameter:
1. solved and have when the spraying of the enterprising row metal of glass-ceramic panel workpiece now and need to heat, and when the added temperature of workpiece that is sprayed cause not spray material with by the inadequate problem of spraying basic unit bonding force.
2. after having solved existing glass-ceramic panel pyroprocessing, do not take sfgd. and easy impaired problem in process of cooling.
3. when having solved existing ordinary hot spray process, it is lower and be subjected to high temperature easily to produce oxide compound that spray material is attached to the lip-deep density ratio of glass-ceramic panel, affects the problem of the original gloss in glass-ceramic panel surface.
