Abstract
The invention discloses a production process of a microcrystalline glass curved plate. The production process comprises the steps of burdening, melting, rolling and annealing to obtain a microcrystalline glass plate, firstly carrying out hot bending treatment on the first microcrystalline glass plate and then crystallizing the microcrystalline glass plate, cooling and polishing after crystallizing. The hot bending treatment comprises the step of placing the microcrystalline glass plate in a hot bending kiln for raising the temperature to 760-850 DEG C and insulating for 2-4h. The crystallizing comprises the step of rapidly raising the temperature to 880-950 DEG C after the hot bending is completed and insulating-crystallizing the microcrystalline glass plate. According to the production process of carrying out hot bending on the microcrystalline glass curved plate and then crystallizing, the microcrystalline glass plate is only subjected to temperature raising treatment, a two-step method of cooling after the microcrystalline glass plate is crystallized at a high temperature and raising the temperature again for carrying out hot bending treatment is saved, thus energy consumption of 50 percent is saved, the production time of the microcrystalline glass curved plate is shortened, and the working efficiency is increased; and because the temperature for hot-bending of the un-crystallized plate is lower, fracture or cracks of the microcrystalline glass plate during hot bending can be reduced, and the quality and the yield are increased.
Description
Technical field
The present invention relates to a kind of production technique of building and ornament materials, be specifically related to a kind of production technique of CURVE DECORATIVE SHEET OF CERAMIC GLASS.
Background technology
Crystallizing glass sheet material belongs to new decorative material for building, and its performance is better than building and ornament materials such as marble, granite, is described as " the green building material of 21st century ".And microcrystalline glass decorative plate is easy to by hot bending process for producing arc sheet material, is used for decorating the cylindric buildings of various different sizes.
The production technique of tradition devitrified glass is mainly rolling process and sintering process, patent name is to utilize granite waste to produce the method for the devitrified glass building decorative plates (patent No.: ZL200910216248.0) adopt the all-electric melting calendering technology to produce crystallizing glass sheet material, all adopt hot bending production technique after the first crystallization when producing the crystallite arc then.Need when producing with this technology sheet material is carried out twice thermal treatment, energy consumption is higher, and production efficiency is lower, therefore the CURVE DECORATIVE SHEET OF CERAMIC GLASS production technique is improved very important.
Find in the production process of research CURVE DECORATIVE SHEET OF CERAMIC GLASS: the sheet material of non-crystallized sheet material softening temperature after than crystallization is low, softening temperature also is lower than crystallization temperature simultaneously, therefore adopt first hot bending, the production technique of crystallization then, only need sheet material is carried out a hyperthermic treatment, just can reach the requirement of hot bending and crystallization, reduce energy consumption, improve production efficiency.
Summary of the invention
In order to need in the production that solves CURVE DECORATIVE SHEET OF CERAMIC GLASS in the prior art sheet material is carried out twice thermal treatment (carrying out hot bending after the crystallization), cause the problem that energy consumption is excessive, production efficiency is low, the invention provides a kind of production technique of CURVE DECORATIVE SHEET OF CERAMIC GLASS, this production technique is carried out crystallization after adopting and earlier the crystallizing glass sheet material hot bending being handled again, only need sheet material is carried out a hyperthermic treatment, both save energy consumption, improved working efficiency again.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
A kind of production technique of CURVE DECORATIVE SHEET OF CERAMIC GLASS, comprise after batching, fusing, calendering, the annealing crystallizing glass sheet material, it is characterized in that crystallizing glass sheet material is carried out hot bending earlier to be handled, crystallization is carried out to sheet material in the back, cooling after the crystallization, polishing.
In the production technique of above-mentioned CURVE DECORATIVE SHEET OF CERAMIC GLASS, the step of described hot bending processing and crystallization is specific as follows: hot bending is handled: place the hot bending kiln to be warming up to 760～850 ℃ crystallizing glass sheet material, insulation 2～4h carries out hot bending and coring and handles; Crystallization: after hot bending is finished, be warming up to 880～950 ℃ rapidly, sheet material is incubated crystallization.
As the preferred embodiments of the present invention, preferably: the time of described insulation crystallization is 40～60min.
As embodiments of the invention, described be cooled to adopt blower fan to sheet material cooling handle, be down to room temperature after, open the hot bending kiln.
The present invention compared with prior art has following beneficial effect:
(1) CURVE DECORATIVE SHEET OF CERAMIC GLASS adopts first hot bending, the production technique of crystallization then, only need sheet material is carried out a hyperthermic treatment, having saved high temperature carries out lowering the temperature after the crystallization to sheet material, again the two-step approach that the hot bending that heats up is again handled, not only save 50% energy consumption, shortened the production time of CURVE DECORATIVE SHEET OF CERAMIC GLASS simultaneously, improved working efficiency.
(2) softening temperature of non-crystallized crystallizing glass sheet material is lower than the sheet material after the crystallization, reduced the energy consumption in the hot bending treating processes, and because the temperature that non-crystallized sheet material hot bending is handled is lower, can reduces sheet material and burst or crackle in the hot bending processing, improve quality and the yield rate of product; Hot bending also is the process of crystallization when handling, and can improve the quality of product.
(3) adopt blower fan to the sheet material processing of lowering the temperature, be down to room temperature after, open the hot bending kiln, to the sheet material processing of progressively lowering the temperature, can reduce sheet material crackle takes place in temperature-fall period.
Embodiment
The invention will be further elaborated and explanation below in conjunction with embodiments of the invention.
Embodiment:
The crystallizing glass sheet material that the present invention adopts is through the crystallizing glass sheet material after batching, fusing, calendering, the annealing, does not pass through crystallization.Can be " utilizing granite waste to produce the method for devitrified glass building decorative plates " (ZL200910216248.0) step a)-d) make crystallizing glass sheet material according to patent name, concrete steps are as follows: a) the grouan waste is pulverized and be 50-350 purpose fine powder; B) above-mentioned grouan fine powder and component thereof are mixed by following weight ratio: granite fine powder 75-90, fluorite powder 2-5, dicalcium powder 6-12, soda ash 1-4, water 1-4; C) above-mentioned compound is sent into the all-electric melting kiln, be fused into glass metal under 1550-1650 ℃ temperature condition, enter clarification, homogenization material road through dog-hole, uptake, clarification, the homogenizing glass metal after good enters to be shaped expects the road; D) above-mentioned glass metal is delivered to the rolling press calendering formation by the material road that is shaped, mold temperature is 1050-1150 ℃, afterwards in type glass temperature is reduced to 850-950 ℃, is delivered to annealing furnace through crossing the roller platform, carries out anneal.Also can adopt the crystallizing glass sheet material that does not pass through crystallization of the method production that utilizes other as the starting material of production CURVE DECORATIVE SHEET OF CERAMIC GLASS of the present invention.
