Abstract
The present invention relates to a technology for manufacturing sintered type glass ceramic, which belongs to the field of building materials. The technology comprises the following processes: (1) glass which is made according to a certain formula is pulverized into broken scraps; (2) the broken glass scraps with particle diameters smaller than ten millimeters are selected and placed in a mold box of refractory materials, on which slurry of the refractory materials is coated, wherein the refractory materials can not be sintered at high temperature, and the broken glass scraps are stacked in a certain thickness; (3) the mold box in which the broken glass scraps are installed is heated up at a rate of 350 DEG C per hour, and is processed with heat insulation within a range of 1020 DEG C to 1200 DEG C, including heat insulation near the softening point of the glass for some time; (4) high temperature which is higher than the heat insulation temperature by 100 300 DEG C is applied to the upper part of the mold box in a short time; (5) the mold box is cooled and processed with heat insulation at the heat insulation temperature; (6) after a process of cooling, finished products can be obtained. By using the technology for manufacturing sintered type glass ceramic of the present invention, the obtained finished products have no or a few air holes on the surfaces, and have smooth surfaces, so that workload of smoothening and polishing can be reduced.
Description
The present invention relates to a kind of relevant novel process of making the decorative devitrified glass material, belong to building materials field.
In the production process of sintering glass ceramics senior building finishing material, often contain pore more or less in the big area crystallizing glass sheet material.Although sheet material itself still can reach higher intensity, the pore that polishes surface of polished has had a strong impact on the outward appearance and the decorative effect of sheet material, and this is one of main difficult problem in the sintering glass ceramics finishing material production process.The void content that how to reduce finished surface becomes the subject matter that sintering glass ceramics development person faces.At present, situation according to similar products at home and abroad, its method of taking is generally by adjusting the glass ingredient prescription, adjust raw material granularity and additive in the devitrified glass sintering process, adopt proper heat treatment technology, still be difficult to fundamentally solve this difficult problem, the crystallizing glass sheet material that obtains at last still contains pore in various degree, not only influence yield rate, also seriously reduced the quality of this devitrified glass finishing material.
The new process of production that the purpose of this invention is to provide a kind of sintering glass ceramics is to reduce or eliminate the pore on devitrified glass surface.
The production technique of sintering glass ceramics of the present invention is as follows:
1, the glass powder that will be suitable for making sintering glass ceramics is broken into the glass disintegrating slag.
2, the glass disintegrating slag of getting above-mentioned grain warp＜10mm is placed in the refractory materials diaphragm capsule that scribbles fire proofed wood slip (as ceramic mud or oxidation aluminium paste).
3, diaphragm capsule is heated up with the speed that is not more than 350 ℃/hour, and near insulation 30-60 minute glass softening point, be incubated 20～120 minutes at 1020 ℃～1200 ℃ again (deciding) by different glass formulas.
4, apply the high temperature that is higher than 100～300 ℃ of above-mentioned holding temperatures on diaphragm capsule top and keep 30-60 second.
5, cooling then, diaphragm capsule insulation 20 minutes to 2 hours (deciding) under above-mentioned holding temperature again by different glass formulas.
6, the cooling cooling gets product.
In first time during insulating process, the glass disintegrating slag begins to fuse each other, sintering and crystallization in above-mentioned technological process.In surpassing the short time high temperature treating processes of softening temperature, softening even levelling phenomenon appear in the devitrified glass surface under high temperature action, have formed the translucent partially-crystallized layer of one deck.The glass disintegrating slag fusion on surface is one, thereby has eliminated surface porosity.Therefore the finished glass plate surface that obtains has reached planeness preferably, thereby has reduced the workload that polishes and polish.
Illustrate that embodiment is as follows:
With the mixture of following composition 1550 ℃ of fusions 3 hours with preparation glass:
Silt: 70 feldspars: 8 CaCO
3: 16 Na
2CO
3: 6
In admixtion, add a certain amount of ZnS and F simultaneously as the nucleus agent.Melten glass obtains the glass disintegrating slag of granulation through shrend, and getting particle diameter is the glass disintegrating slag of 4～10mm, and it is stored in the diaphragm capsule, and the diaphragm capsule inwall scribbles Al
2O
3Powder.The transmission roller-way of diaphragm capsule being put into tunnel furnace is heated to 1080 ℃ of sintering and crystallization from room temperature, heating rate is not more than 200 ℃/hour, diaphragm capsule was controlled at 70 minutes in the time of this temperature section, be 1350 ℃ terraced temperature area then by one section upper temp, making its working time is 4 minutes, by the humidity province of 1080 ℃ of kiln back segments, be controlled to be 40 minutes during this period of time again.The temperature controlling instruments parameter of adjustment kiln and the travelling speed of roller-way reach the requirement of each temperature section soaking time with control.Diaphragm capsule cools down at last, obtains patterned glass.Thus obtained finished surface is comparatively level and smooth, has pore hardly.Through grinding and polishing obtains the microcrystal glass plate of sparkling and crystal-clear bright band green crystal decorative pattern.
Finished surface pore-free that adopts sintering glass ceramics production technique of the present invention to make to obtain or pore seldom, and surfacing have reduced the polishing work amount that polishes.
