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 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 making thereof.
Background technology
At present, on Household induction cooker glass-ceramic panel surface, or on the material surface with devitrified glass characteristic close during the material of metallize, 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 glass-ceramic panel surface, or on the material surface with devitrified glass characteristic close time, has following shortcoming:
1. in the materials process of metallize, sprayed substrate need to heat thousands of degrees Celsius, and it is inadequate to work as the added temperature of substrate being sprayed, also easily causes that 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 pyroprocessing, in process of cooling, do not take sfgd., easily damaged.
3. be subject 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 subject to high temperature can produce oxide compound, affect devitrified glass and the gloss original with the surface 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 ordinary hot spraying method also can spray certain thickness coating, it cannot 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 devitrified glass surface, or on the material surface with devitrified glass characteristic close time, have following shortcoming:
1. during cold spraying, spray material is with inadequate by spraying basic unit bonding force.
2., while adopting chemical mode and silk-screen mode, metallic substance thickness (generally can only accomplish that 0.05mm is following) and density are restricted.
3. while adopting silk-screen mode, also need later stage drying course, production cost is high.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect that above-mentioned prior art exists, provide a kind of 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 at glass-ceramic panel or local surfaces are sprayed with metal level or the metal compound layer that a thickness is 0.01～1mm, and concrete procedure of processing is as follows: first sandblast is carried out in the surface of glass-ceramic panel or local surfaces; Then, on the glass-ceramic panel surface through sandblasting, with metal spraying powder, carry out supersonic spray coating again, processing requirement is wherein 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 powder feeding rate is 40～100g/min.
The present invention carries out metallic substance spray treatment when glass-ceramic panel surface, and because metal spraying powder is little, speed is fast, and in spraying process, glass-ceramic panel surface temperature rise, lower than 100 ℃, can not cause glass-ceramic panel to break because temperature rise is too high; The mill durability performance of the metal level obtaining by working method of the present invention or metal compound layer is good, density and hardness is high, and the excellent bonding performance of metal level or metal compound layer and glass-ceramic panel, does not need later stage drying course, and tooling cost is low.
Further, preferred metal or other the similar metallic compounds such as silver, copper, aluminium, zinc, cobalt, cadmium, nickel, iron, platinum, lead, antimony, titanium or manganese of the material of described metal spraying powder.
Further, the smart rugosity Ra of glass-ceramic panel after sandblast is 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 is to provide 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, by adjusting spraying coating process and corresponding spraying parameter, has the following advantages:
1. solved existing when the spraying of the enterprising row metal of glass-ceramic panel workpiece need to heat, and when the added temperature of workpiece being sprayed cause not spray material with by the inadequate problem of spraying basic unit bonding force.
2. solved after existing glass-ceramic panel pyroprocessing, in process of cooling, do not taked sfgd. and easy impaired problem.
3. while having solved existing ordinary hot spray process, it is lower and be subject 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.
