Microcrystal glass combined plate material and its production technology

Abstract

A microcrystal glass compounded vitrified plate is composed of surfacial layer (microcrystal glass) and bottom layer (vitrified tile), and is prepared through preparing raw materials, die pressing, smelting, vitrifying, cutting edge, coarse grinding, further grinding, fine grinding, coarse polishing, fine polishing, chamfer, drying and classifying. Said vitrified tiles are prepared from clay, quartz, feldspar sand, and talc. Said microcrystal glass is prepared from quartz, feldspar and calcite. Its advantages include high adhesion, high strength and lustre, moderate cost, and high antiwear and anticorrosion performance.

Description

Technical field: [0001] The invention belongs to the field of building decoration materials, and in particular relates to a glass-ceramic composite vitrified plate and a production process for pressurized (thermal) molding of fired ceramic products and glass products. Background technique: [0002] The glass-ceramic decorative plate has excellent characteristics such as high strength, good gloss, corrosion resistance and wear resistance. However, in the production of glass-ceramics, the cost of sintered glass-ceramic plates is often high. The important reason is that the plate needs a certain thickness, often greater than 12mm, so a large amount of glass-ceramic slag is required. , and this process consumes energy and materials, which occupies a considerable cost. In the subsequent crystallization process, a tunnel kiln or an edge kiln is required, and the production cycle is often longer, and the longer sintering time causes an increase in energy consumption, which is also...

AI Technical Summary

Problems solved by technology

In the subsequent crystallization process, a tunnel kiln or a rib kiln is required, and the production cycle is often longer. The longer sintering time causes an increase in energy consumption, which is also an important aspect.

In addition, in the process of grinding and polishing the plate, the workload is relatively large, and a lot of manpower and material resources are required.

Therefore, how to reduce the cost of glass-ceramic products has actually become one of the main problems faced in the production of sintered glass-ceramics, which is why it is difficult to promote in the market despite its excellent vitrification properties and surface patterns. the reason for

Although the cost of traditional ceramic plates is low, the surface of a single ceramic vitrified tile still has a certain degree of dirt absorption after polishing. Although it has been improved, there are still certain deficiencies. Due to its poor performance and low grade, it is difficult to occupy a place in high-grade decorative materials
