Abstract
The invention discloses a glass ceramic production process, belonging to the technical field of glass production. In the glass ceramic production process, a chemical component control technology, a glass melting technology, a glass crystallization technology and a product finishing technology are integrated, so that the glass ceramic production process is specified as follows: material mixing, material melting, high temperature treatment, molding, crystallizing and annealing, processing of a finished product and cutting to be put into storage. The glass ceramic production process has the advantages that the process technologies in the glass ceramic production process are specified, the production efficiency of the glass ceramic is improved, and the product percent of pass is improved; and the glass ceramic production process provides preconditions for breaking the application limitation of glass ceramic products and enlarging the market of products.
Description
Technical field
The present invention relates to field of glass production technology, be specifically related to a kind of devitrified glass production technique.
Background technology
Devitrified glass is as the selectable finishing material of one, there is many excellent performances, as density is little, quality is fine and close, there is no pore, waterproof, airtight, softening temperature is high, chemical stability and Heat stability is good, physical strength and hardness high, electric property is excellent, but because devitrified glass cost is high, the devitrified glass of traditional mode of production due to production operation lack of standardization, for each production stage control and be connected not rigorous, the devitrified glass flaw produced is many, condemnation factor is high, often there is a large amount of manufacturability pore in surface layer of glass and inside thereof, and the performance such as folding strength and water tolerance is not strong, limit the Application Areas of devitrified glass, thus constrain it greatly use and promote.
In order to break through the application limitation of devitrified glass, doing large devitrified glass produce market, needing the production technique of specification devitrified glass.
Summary of the invention
The object of the present invention is to provide a kind of devitrified glass production technique, its specification Technology of devitrified glass production process, improves the production efficiency of devitrified glass, improves conforming product rate.
Technical solution problem of the present invention adopts following technical scheme:
There is provided a kind of devitrified glass production technique, it is characterized in that: chemical Composition Control technology used produced by devitrified glass by it, glass melting technology, glass micritization technology, product finishing technique are integrated, the production technique of specification devitrified glass is as follows:
1) batch mixing: various starting material (sand, calcite, feldspar, soda ash, other etc.) are proportionally carried out weigh, mix and mention cellar for storing things head feed bin;
2) melt: the raw material of mixing is sent to after high temperature melting, clarification are carried out in molten cellar for storing things and flow into material pond by flow liquid road, extremely cold with the bath of pressurization hydraulic giant when staying, after making vitreum shrend become the glass particle of below 6mm, dehydration row rises, then dries by own temperature, promotes into grog storehouse for subsequent use after sieving;
3) high-temperature molding subsequent annealing: by various glass crystal according to all size successively refractory slab arrangement → brush release agent → cellar for storing things car die-filling → material charging forming → enter cellar for storing things → melt molding → crystallization → cellar for storing things → form removal of annealing → go out to get plate, thus complete the high-temperature molding subsequent annealing of glass crystal;
4) processed finished products: the glassy product of high-temperature molding crystallization is carried out roughly grind → refine → rough polishing → essence throwing → cutting → edging, thus form devitrified glass finished product;
5) detect warehouse-in: by the devitrified glass finished product of processing through production testing → cutting → packaging warehouse-in, need before encapsulation to make product meet performance sampling observation requirement.
The present invention compared with prior art, its beneficial effect is: provide a kind of devitrified glass production technique, its specification Technology of devitrified glass production process, improve the production efficiency of devitrified glass, improve conforming product rate, for devitrified glass product is broken through application limitation, expanded the prerequisite of produce market.

2) melt: the raw material of mixing is sent to after high temperature melting, clarification are carried out in molten cellar for storing things and flow into material pond by flow liquid road, extremely cold with the bath of pressurization hydraulic giant when staying, after making vitreum shrend become the glass particle of below 6mm, dehydration row rises, then dries by own temperature, promotes into grog storehouse for subsequent use after sieving;
3) high-temperature molding subsequent annealing: by various glass crystal according to all size successively refractory slab arrangement → brush release agent → cellar for storing things car die-filling → material charging forming → enter cellar for storing things → melt molding → crystallization → cellar for storing things → form removal of annealing → go out to get plate, thus complete the high-temperature molding subsequent annealing of glass crystal;
4) processed finished products: the glassy product of high-temperature molding crystallization is carried out roughly grind → refine → rough polishing → essence throwing → cutting → edging, thus form devitrified glass finished product;
5) detect warehouse-in: by the devitrified glass finished product of processing through production testing → cutting → packaging warehouse-in, need before encapsulation to make product meet performance sampling observation requirement.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
