Problems solved by technology

[0002] At present, due to the formula composition and molding process of ordinary large porcelain plates, even if the thickness of the porcelain plate is controlled to 8mm, the light transmission of the porcelain plate cannot be realized. Long working hours, many damages, non-standard product specifications and many other problems
In the prior art, if the large porcelain plate is to be made thinner, problems such as unevenness, cracking, wing angle, deformation and other problems on the surface of the porcelain plate body are prone to occur, which not only increases the production cost, but also limits the wide application of large porcelain plates

Abstract

The invention discloses a high-transmittance, high-weight and high-strength large porcelain plate. The porcelain plate adopts natural raw mineral materials and industrial chemical materials, and comprises the following material components in percent by weight: 30 to 35 percent of Longyan kaolin, 10 to 12 percent of quartz, 5 to 8 percent of aluminum oxide, 20 to 25 percent of feldspar, 4 to 6 percent of talcum, 1 percent of calcite, 3 to 7 percent of potash feldspar, 1 to 3 percent of albite, 10 to 12 percent of bone meal, 5 to 6 percent of yttrium oxide, and 3 percent of zirconium oxide. Theporcelain plate is formed through the following processes: washing, compounding, ball milling, adding 8 percent of porcelain powder, deironing, filtering, mud treatment, forming, primary drying, fettling, biscuiting, truing, glazing, secondary drying and glaze firing. The porcelain plate solves the problems in terms of whiteness, transparency, glaze surface hardness of products through control ofa formula and a forming technology, can be applied to manufacture of indoor or outdoor artistic walls or artistic atmosphere lampshades with backlight effect, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and specifically relates to a high-transparency, high-white, high-strength large-scale porcelain plate. Background technique [0002] At present, due to the formula composition and molding process of ordinary large porcelain plates, even if the thickness of the porcelain plate is controlled to 8mm, the light transmission of the porcelain plate cannot be realized. There are many problems such as long working hours, many damages, and non-standard product specifications. In the prior art, if the large porcelain plate is to be made thinner, problems such as unevenness, cracking, wing angle, deformation and other problems on the surface of the porcelain plate body are prone to occur, which not only increases the production cost, but also limits the wide application of large porcelain plates . Contents of the invention [0003] The technical problem to be solved by the pre...
