Problems solved by technology

[0002] In the field of ceramics, bright red glaze decoration is favored by consumers for its noble, rich and bright colors, but this kind of glaze has poor thermal stability and is not acid-resistant. When used in daily utensils, its lead and cadmium will dissolve The limit value cannot meet the international health standard
Moreover, the thermal stability and acid corrosion resistance of the bright red glaze are poor, and the limit values ​​of lead and cadmium dissolution are high.

Embodiment Construction

[0020] Accurately weigh and mix the above-mentioned raw material components according to the specified ratio, melt at 1250°C, pour into water and quench into a frit; take 100 parts of the above-mentioned frit, add 6 parts of color base, 50 parts of water, and put it into a ball mill for ball milling After 72 hours, pass through a 250-mesh sieve to obtain a low-temperature bright red glaze at 760°C to 800°C.

[0021] According to the above process requirements, in 1124 # Glaze is applied on the milk cup. After testing, the product performance is as follows:

[0022] (1) Chromaticity value (chromaticity coordinate value): saturation (L) 36.31, redness value (a) 58.75, blueness value (b) 40.30.

[0023] (2) Dissolution value of lead and cadmium: measured value (mg)

[0024]

[0025] It can be seen from the above that the product fully complies with international hygienic standards, and it is an ideal low-temperature bright red glaze for ceramics that meets internation...

Abstract

A low-temp oriental red enamel for ceramics is proportionally prepared from Al2O3, CaO, Li2O, SiO2, ZnO, ZrO2, B2O3, Na2O, La2O3, PbO, K2O and SnO2 through mixing, smelting, quenching in water to become blocks, adding pigment and water, ball grinding and sieving.

Description

technical field [0001] The invention relates to a low-temperature bright red glaze for ceramics and a manufacturing method thereof. Background technique [0002] In the field of ceramics, bright red glaze decoration is favored by consumers for its noble, rich and bright colors, but this kind of glaze has poor thermal stability and is not acid-resistant. When it is used for daily utensils, its lead and cadmium will dissolve Limit values ​​cannot meet international health standards. Moreover, the thermal stability and acid corrosion resistance of the bright red glaze are poor, and the limit values ​​of lead and cadmium dissolution are high. Contents of the invention [0003] The purpose of the present invention is to prepare a kind of pottery and ceramics decoration for daily use, which has bright and plump color, good thermal stability and acid resistance when fired rapidly at 760 ° C to 800 ° C, so that the dissolution limit of lead and cadmium can be obtained. A low-tem...
