Problems solved by technology

[0003] Due to the difficulty in controlling the temperature of crystallization, the board obtained by secondary sintering has the following defects in the glass-ceramic board: there are bubbles inside, and the bubbles will appear on the surface of the board after polishing for 1-2 mm, with a diameter of about 1 mm, which is very small. unsightly
[0004] Based on the above shortcomings, glass-ceramic plates with many high-quality properties produced by the prior art can only be used as floor tiles, and cannot be made into glass-ceramic table tops. This has always been an urgent problem to be solved in this industry.
The reason is mainly because the glass-ceramic plate is used as a floor tile, generally only need to grind its surface, the requirement for the grinding thickness is relatively small, and no air bubbles will appear, and if it is used as a countertop, its side and side edges need to be rounded If the edge is ground, the capillary pores generated by the air bubbles will undoubtedly be exposed, resulting in an unattractive and durable countertop

Embodiment 1

[0060] Embodiment 1: as figure 1 The shown glass-ceramic counter panel is prepared by the following method:

[0061] 1) The ingredients of the batch are as follows: 60 parts of quartz sand, 10 parts of limestone, 11 parts of dolomite, 12 parts of soda ash, 2 parts of iron oxide, and 2 parts of chromium oxide.

[0062] 2) the first sintering of glass pellets,

[0063] ①Provide a glass melting furnace and a glass pool furnace,

[0064] ② Send the batch material into the glass pool furnace and then send it to the glass melting furnace for melting. The melting temperature is 1300°C. After the glass solution is uniform in composition and the bubbles are clear, it is water-quenched into 1-5mm particle size. Dry to obtain glass pellets.

[0065] 3) Provide a barrier layer 1 according to the size of the required table top, which determines at least one surface critical layer of the glass pellets, the surface of the barrier layer 1 is covered with fire-resistant and anti-adhesive la...

Embodiment 2

[0070] The process of this embodiment is the same as that of Embodiment 1, only

[0071] The melting temperature of the first sintering is 1600°C;

[0072] The second sintering microcrystallization treatment temperature (i.e. holding temperature) is 1120°C for 50 minutes;

[0073] For the third sintering, the microcrystallization treatment temperature during sintering is 1136°C-1140°C, that is, the change of single crystallization temperature is controlled between 0°C-4°C, and the treatment time is 70 minutes.

Embodiment 3

[0074] Embodiment 3: as figure 2 , image 3 The shown glass-ceramic cooktop panel is prepared by the following method:

[0075] 1) The ingredients of the batch are as follows: 60 parts of quartz sand, 10 parts of limestone, 11 parts of dolomite, 12 parts of soda ash, 2 parts of iron oxide, and 2 parts of chromium oxide.

[0076] 2) the first sintering of glass pellets,

[0077] ①Provide a glass melting furnace and a glass pool furnace,

[0078] ②Put the batch materials into the glass pool furnace and melt them in the glass melting furnace. The melting temperature is 1400°C. After the glass solution is uniform in composition and the bubbles are clear, it is quenched into 1-5mm particle size and baked. Dry to obtain glass pellets.

[0079] 3) Provide a barrier layer 1 according to the size of the required table top, which determines at least one surface critical layer of the glass pellets, the surface of the barrier layer 1 is covered with fire-resistant and anti-adhesive l...

Abstract

The present invention relates to microcrystal glass top plate as one kind of building member and its production process and application. The production process includes the first sintering of the mixture of quartzite, limestone, etc. to form granular glass material; spreading the granular glass material inside one shaped frame and the second sintering to form the semi-finished microcrystal glass member; the third sintering of the cooled member inside one crystallizing furnace at 1110-1140 deg.c and temperature variation within 10 deg.c for 50-70 min; and polishing, grinding and shaping. The production process can form top plate with compact structure, no bubble, high wear resistance, easy trimming, good appearance and texture, and is easy to control.

Description

technical field [0001] The present invention relates to a kind of thin building component and its manufacturing method which are made of concrete or other stone materials and used for building parts, especially to a glass-ceramic countertop and its preparation method and application. Background technique [0002] Glass-ceramics, also known as glass ceramics, is a sintered body composed of crystalline phases and residual glass phases. It is a material made by crystallizing glass batches with a certain raw material composition under controllable conditions. The glass-ceramics in the prior art generally have the following manufacturing process: first, the raw materials are melted at a high temperature in a glass melting furnace and then quenched to obtain pellets, which is the first sintering; In the mold, microcrystallization and sintering in a ceramic kiln (the second sintering), and finally stone cutting mechanical polishing, grinding, and shaping to obtain glass-ceramic bui...
