Abstract
The invention discloses a production technology of a toughened glass. The production method comprises the following steps in sequence: cutting a piece of flawless flat glass to be toughened, trimming the edges, washing and saving the dissected flat glass for later used; horizontally placing the pre-treated flat glass on a roller bed, transferring the flat glass to a toughening furnace by the roller bed; heating the flat glass in the toughening furnace to a temperature of 550-760 DEG C, maintaining the temperature for 280 to 460 seconds; then transferring the flat glass which has been thermally treated to a quenching area by a roller bed, horizontally placing the flat glass on the roller bed, and cooling the flat glass by cooling air for 18 to 22 seconds under a pressure of 12 to 26 KPa so as to obtain the finished product. The toughened glass produced by the provided production technology has the advantages of high strength, low cost, and high yield, moreover, the equipment is simple, and the investment is small.
Description
Technical field
The invention belongs to field of glass production technology, be specifically related to a kind of production technique of toughened glass.
Background technology
At present, the tempering of glass mainly contains physical toughened and chemical tempering two kinds, and chemical tempering is mainly the ion exchange method of Nitrates.Physical toughenedly mainly contain particulate tempering, mist tempering method etc.Chemical tempering exists that the production cycle is long, efficiency is low and production cost is high, fragment and simple glass similar, the problems such as poor stability.Physical toughened exist that speed of cooling is slow, energy consumption is high, for thin glass, also there is the problem of glass deformation in toughening process.
Summary of the invention
The object of the invention is to, provide a kind of production technique of toughened glass, the toughened glass adopting production technique of the present invention to produce has that intensity is high, cost is low, yield rate advantages of higher, and equipment is simple, invests less.
The production technique of toughened glass provided by the invention, it comprises the following steps successively:
(1) for subsequent use by not having defect to clean after the sheet glass cutting edging of tempering;
(2) pretreated sheet glass in (1) is placed horizontally on roller-way, sends in annealing furnace by roller-way;
(3) sheet glass sent in annealing furnace is heated to 550 ~ 760 DEG C, keeps 280 ~ 460 seconds;
(4) sheet glass after heat treated is delivered to quench area by roller-way, sheet glass is placed horizontally on roller-way, carries out cooling 18-22s, obtain finished product with the cooling air that blast is 12KPa ~ 26Kpa.
The production technique of toughened glass provided by the invention, its beneficial effect is; The toughened glass adopting production technique of the present invention to produce has that intensity is high, cost is low, yield rate advantages of higher, and equipment is simple, invests less.
Embodiment
Below in conjunction with an embodiment, the production technique of toughened glass provided by the invention is described in detail.
Embodiment
The production technique of the toughened glass of the present embodiment, it comprises the following steps successively:
(1) for subsequent use by not having defect to clean after the sheet glass cutting edging of tempering;
(2) pretreated sheet glass in (1) is placed horizontally on roller-way, sends in annealing furnace by roller-way;
(3) sheet glass sent in annealing furnace is heated to 640 DEG C, keeps 350 seconds;
(4) sheet glass after heat treated is delivered to quench area by roller-way, sheet glass is placed horizontally on roller-way, carries out cooling 20s, obtain finished product with the cooling air that blast is 20Kpa.
