Problems solved by technology

At present, thin-bodied porcelain plates are all made by hand, and their thickness is generally greater than 1mm, and there are many problems such as high work intensity, long working hours, frequent damage, and non-standard product specifications.
In the prior art, if the thin-bodied porcelain plate is to be made thinner, problems such as uneven surface, cracking, wing angle, and deformation of the porcelain plate body are prone to occur, which not only increases the production cost, but also limits the thin-bodied porcelain plate. widely used

Abstract

The invention discloses a high-permeability high-whiteness high-strength eggshell porcelain plate which is characterized by comprising the following natural ore raw materials and industrial chemical raw materials in percentage by weight: 30-35% of Longyan kaolin, 10-12% of quartz, 5-8% of aluminum oxide, 30-35% of feldspar, 4-6% of talc, 1%b of calcite, 2-5% of potassium feldspar, 1-2% of albite,8% of bone meal and 3-5% of yttrium oxide, and a product of the eggshell porcelain plate is prepared through procedures of washing, blending, ball milling, addition of 4% of external porcelain powder,deironing, filtration, slurry treatment, molding, primary drying, blank trimming, biscuiting, refining, glazing, secondary drying and glaze firing. By controlling formula and molding processors, theproblems of whiteness, transparency, glaze surface hardness and flatness of the product can be solved, and the obtained high-permeability high-whiteness high-strength eggshell porcelain plate productcan be used as decorative lamp shades in families, offices, indoor places and the like, and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a high-transparency, high-white, high-strength thin-bodied porcelain plate. Background technique [0002] Thin-bodied porcelain, commonly known as eggshell porcelain, is famous all over the world for being "as thin as paper, as white as jade, as bright as a mirror, and as loud as a chime". Thin-bodied porcelain has shown great application prospects in the ceramic market due to its light material, good light transmission, and fine texture. At present, thin-bodied porcelain plates are all made by hand, and their thickness is generally greater than 1mm, and there are many problems such as high work intensity, long working hours, frequent damage, and non-standard product specifications. In the prior art, if the thin-bodied porcelain plate is to be made thinner, problems such as uneven surface, cracking, wing angle, and deformation of the porcela...
