Embodiment 1

[0026] Take the following raw materials: 3.00 tons of calcined alumina + 6.67 tons of calcined talc + 6.67 tons of ultra-white ball clay + 1.00 tons of calcined kaolin + 2.33 tons of washed kaolin + 7.67 tons of low-temperature feldspar + 6.00 tons of Ruilong sand.

[0027] Weigh according to the above-mentioned raw material ratio and transport it into the ball mill; after being ground into a slurry by the ball mill, pump it to the spray tower; granulate through the spray tower, let it stand for 24 hours to make the powder moisture reach the consistency, and then send it to the press for compression molding; after drying , raised to 1260°C at a rate of 20°C / min, held at a temperature of 20 minutes, fired in a kiln, and then lowered to cool down; polished by a polishing machine.

[0028] The batch material of the above composition uses magnesium in talc and potassium and sodium in other materials as flux, Al 2 o 3 A relatively high content can strengthen the skeleton compositi...

Embodiment 2

[0030] The following weights of raw materials were taken: 2.00 tons of calcined alumina + 13.33 tons of calcined talc + 6.67 tons of ultra-white ball clay + 3.33 tons of washed kaolin + 5.33 tons of low-temperature feldspar + 3.33 tons of Hunan high-temperature sand.

[0031] Weigh according to the above-mentioned raw material ratio and transport it into the ball mill; after being ground into a slurry by the ball mill, pump it to the spray tower; granulate through the spray tower, let it stand for 30 hours to make the powder moisture reach the consistency, and then send it to the press for compression molding; after drying , raised to 1180°C at a rate of 30°C / min, held for 40 minutes, fired in a kiln, and then cooled down; polished by a polishing machine, that is.

[0032] The batch material of the above composition uses potassium and sodium in the green body as a flux. The content of talc is relatively high, and the content of aluminum is relatively small. The oblique enstati...

Embodiment 3

[0034] The following weights of raw materials were taken: 3.00 tons of calcined alumina + 12.67 tons of calcined talc + 6.67 tons of ultra-white ball clay + 3.33 tons of washed kaolin + 4.33 tons of low-temperature feldspar + 3.33 tons of Jiangxi white sand.

[0035] Weigh according to the above-mentioned raw material ratio and transport it into the ball mill; after being ground into a slurry by the ball mill, pump it to the spray tower; granulate through the spray tower, let it stand for 27 hours to make the powder moisture reach the consistency, and then send it to the press for compression molding; after drying , raised to 1210°C at a rate of 28°C / min, held at a temperature of 30 minutes, fired in a kiln, and then cooled down; polished by a polishing machine, and obtained.

[0036] The batch of the above composition uses potassium sodium as a flux, and the content of talc (MgO) is relatively high, and Al 2 o 3 The content is also relatively high, which can strengthen the s...

Abstract

This invention relates to a ultrawhite polishing brick. According to weight shares the raw materials includes: calcined alumina 5 to 10 shares, burning talcum 10 to 40, ultrawhite ball clay 18 to 25, water washing kaolin 5 to 12, low temperature feldspar 13 to 25, middle and high temperature porcelain sand 10 to 18 shares. The process includes: ball milling, spraying and corning, shaping by quenching, adobe drying and kiln burning. This invention has high whiteness, good thermostability, and avoid zirconium silicate radioactive problem.

Description

technical field [0001] The invention relates to the technical field of inorganic silicates, specifically to the technical field of ceramic tiles, and more specifically to an ultra-white polished tile. technical background [0002] Usually, white represents purity and flawlessness, so ultra-white ceramic tile products are often loved by consumers. General ultra-white bricks are made of SiO 2 -Al 2 o 3 -R 2 O as the basic system, plus zirconium silicate whitening, the whiteness is difficult to exceed 58 (standard substance BaSO 4 The whiteness is 100), especially when the amount of zirconium silicate is too much, the radiation index of the green body will increase significantly, causing obvious damage to the human body; the firing temperature will also increase significantly, and the firing cost of the finished product will also increase accordingly. Contents of the invention [0003] The object of the present invention is to provide an ultra-white polished tile. The p...
