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 specifically relates to a high-permeability, high-white, and high-strength thin porcelain plate.Background technique[0002]Thin-feet porcelain is commonly known as eggshell porcelain, and is world-renowned for its "thin as paper, white as jade, bright as a mirror, and sound like a chime". Thin-walled porcelain has shown great application prospects in the ceramic market due to its light material, good light transmittance, and fine texture. At present, the thin porcelain slabs are all made by hand, and their thickness is generally greater than 1mm, and there are many problems such as high working strength, long working hours, many damages, and non-standard product specifications. In the prior art, if the thin ceramic slabs are to be made thinner, the surface of the ceramic slab body is prone to problems such as unevenness, cracks, wing angles, deformation, etc., which not only in...
