Abstract
The large-scale devitrified glass decoration plate comparable to natural stone material in appearance and physical-chemical performance is made up through preparing glass particles, moulding and vibrating pre-pressing for shaping, sintering in tunnel kiln, grinding and polishing.
Description
The present invention relates to the production technique of large devitrified glass decorative board, more specifically to utilizing sintering process to make the production technique of large devitrified glass decorative board, this dalle can be used for skin, ground and inner wall decoration.
The decorative devitrified glass material is a kind of finishing material of novel high-grade, and it has can compare U.S. even better appearance luster with lithotome, and decorative pattern and physicochemical property can be used to substitute in a large number lithotome.At present, the production technique of microcrystalline glass decorative plate mainly contains two kinds: rolling process and sintering process, because rolling process complex manufacturing, the equipment requirements height, investment is big, though this method production output is big, but still do not form stable industrialized mass production at present both at home and abroad, the devitrified glass of especially big specification, although and sintering process output is lower, but because its technological process is disconnected, so its technology ratio is easier to control, the integrated requirement of equipment automatization is lower and scale of investment is less and become the method that present crystallizing glass sheet material manufacturing enterprise mainly adopts, for example the open CN 1072398A of Chinese patent discloses the method for utilizing feldspar mine tailing sintering process to make the devitrified glass decoration materials, but existing sintering process prepares the production technique of devitrified glass decoration materials and all has a defective, the uneven whole degree of glass surface of promptly passing through after the sintering crystallization is higher, particularly when producing the product of big specification, because this defective makes devitrified glass need spend very long grinding, polishing time, its yield rate is lower, has increased production cost.
The object of the present invention is to provide a kind of production technique of utilizing sintering process to prepare large devitrified glass decorative board, this technology can be eliminated existing above-mentioned defective in the prior art, thereby produces the crystallizing glass sheet material of big specification.
