⑵ at glass surface spraying or dipping chemical liquid, and this chemical liquid is commercially available metal oxide chemical glass tempering soup, and concentration is controlled at the solution saturation ratio;
⑶ be placed on the glass of two sprayings or dipping chemical liquid to close sheet on the platform, and edge sealing advances process furnace again to carry out dry method and heat, and heating in the stove is 200-800 ℃, time 1.5-10 hour; Finish exhaust simultaneously, vacuumize, edge sealing, seal process, temperature is reduced to come out of the stove and is promptly obtained finished product.
And described glass comprises ordinary plate glass, curved glass, tubing or bar, or toughened glass.
And the chemical liquid coating of described glass surface is a single or double, and one or many spraying or dipping do not trickle until the soup amount of being coated with.
And described chemical liquid is that alkaline potassium salt is main water or ethanol chemistry glass tempering soup.
The present invention solves its technical problem and is achieved through the following technical solutions:
Advantage of the present invention and beneficial effect are:
1, the present invention uses ordinary plate glass to carry out dry method behind surface spraying or dipping chemical liquid to heat, can directly produce toughened vacuum glass, technology is simple, and is with low cost, opened up the beginning that simple glass directly produces toughened vacuum glass, for the development of glass industry is laid a good foundation.
2, the present invention's glass that also can use tempering to cross adopts chemical drying method tempering once more in process furnace, not only obtained vacuum toughened glass, and can make toughened glass carry out second compensation through the annealing stress relaxation phenomenon that high temperature produced by present method, the glass surface stress decrease problem of having avoided toughened glass to cause through annealing, resulting vacuum toughened glass still has very strong surface stress and intensity, be particularly suitable for some spray of molten steel technologies that physical toughened glass is difficult to finish, as the tempering of glassworks such as system mirror, abnormity, rod, pipe.
3, the domestic and international blank that can't directly make vacuum glass with simple glass and toughened glass has been broken in appearance of the present invention, greatly reduces field shatter proof glass manufacturing use costs such as building, reduces glass heats number of times and thermal damage, improves intensity and life-span.
