Problems solved by technology

The calendering method is a continuous production, with a large one-time investment, and it is difficult to diversify the product varieties. Moreover, the produced glass-ceramic is similar to ceramics, has no jade texture, the product is thin, and the decorative effect is not good; the sintering method adopts intermittent production technology. The production organization is relatively flexible, and self-melting and self-leveling processes are adopted, but there are a large number of technological pores in the surface and inner layers of the produced products, and it is difficult to produce uniform fabrics by this method, which can easily cause the flatness of the product to exceed the standard, so the product is comprehensive. lower rate, higher cost
Therefore, the use occasions and scope of the glass-ceramic decorative products produced by the above two processes are greatly limited.

Embodiment 1

[0020] The raw materials used in glass-ceramics in this example include the following components and weight content: SiO 2 50%, CaO20%, Al 2 o 3 3%, Na 2 O+K 2 O11%, B 2 o 3 0.5%, BaO8%, ZnO0.5%, Sb 2 o 3 1%, Cl0.2%; the above-mentioned raw materials are made into glass-ceramic pellets by the existing technology, and flat glass is made by the existing casting method. On the mold, and then evenly spread the prepared glass-ceramic granules on it, then push the kiln car into the kiln, sinter at 1000°C-1230°C, and then crystallize to produce low porosity glass. Glass-ceramic, the resulting glass-ceramic has patterns on it and no pores on the surface.

Embodiment 2

[0022] The raw materials used in glass-ceramics in this example include the following components and weight content: SiO 2 67%, CaO10%, Al 2 o 3 15%, Na 2 O+K 2 O3%, B 2 o 3 4%, BaO2%, ZnO5%, Sb 2 o 3 0.3%, Cl 2%; the above-mentioned raw materials are made into flat glass by the existing casting method and glass-ceramic pellets are prepared by the prior art, then the flat glass is quenched, and the quenching temperature is 800 ° C, so that cracks appear, Move the obtained flat glass below 900°C to the mold on which the release agent has been laid, and then evenly spread the glass-ceramic granules on it, and then put the flat glass covered with the glass-ceramic granules in the kiln Sintering at 1000°C-1230°C, followed by crystallization can produce glass-ceramics with low porosity. The obtained glass-ceramics has patterns on the top and cracks on the bottom.

Embodiment 3

[0024] The raw materials used in glass-ceramics in this example include the following components and weight content: SiO 2 60%, CaO15%, Al 2 o 3 9%, Na 2 O+K 2 O8%, B 2 o 3 3%, BaO5%, ZnO3%, Sb 2 o 3 1.2%, Cl 1%; use the existing sintering method to make flat glass and pellets from the above raw materials, and press the glass pellets into the surface of the incompletely hardened glass by rolling the flat glass above 700°C to form A substrate with glass pellets embedded on its surface. Move the obtained flat glass base material to the mold where the release agent has been laid at below 900°C, and then evenly spread the glass-ceramic pellets with the same composition as the above-mentioned raw materials on it, and then push the kiln car into the kiln. Sintering at 1000-1230°C and crystallization can produce glass-ceramics with low porosity.

[0025] The surface of the glass-ceramics prepared by the above method has no pores and beautiful patterns, and can be processed i...

Abstract

The invention relates to a production method of low-porosity glass-ceramics, that is, evenly spreading glass granules on a single-layer or multi-layer glass plate base material, and then sintering at 900°C-1230°C, and crystallizing Glass-ceramic with low porosity. The ingredients contained in the raw materials used and their weight percentages are: SiO 2 50%-67%, CaO10%-20%, Al 2 o 3 3%-15%, Na 2 O+K 2 O3%-11%, B 2 o 3 0.5%-4%, BaO2%-8%, ZnO0%-5%, Sb 2 o 3 0.3%-1%, Cl0%-2%. The glass-ceramic produced by this method has a very high yield rate, low overall cost, low porosity, good flatness, good color variety and shape designability, etc., which greatly expands the scope of use of glass-ceramics .

Description

technical field [0001] The invention relates to a production method of glass-ceramics, in particular to a production method of low-porosity glass-ceramics. Background technique [0002] At present, the production process of glass-ceramics basically adopts two processes: one is calendering, and the other is sintering. The calendering method is a continuous production, with a large one-time investment, and it is difficult to diversify the product varieties. Moreover, the produced glass-ceramic is similar to ceramics, has no jade texture, the product is thin, and the decorative effect is not good; the sintering method adopts intermittent production technology. The production organization is relatively flexible, and self-melting and self-leveling processes are adopted, but there are a large number of technological pores in the surface and inner layers of the produced products, and it is difficult to produce uniform fabrics by this method, which can easily cause the flatness of t...
