Embodiment 1

[0022] Assuming that the total weight of various raw materials is 4000kg, in terms of weight percentage, the surface glaze includes the following effective components: 20.00% of high-temperature matte frit, 10.54% of air knife soil, 16.98% of calcite, 20.19% of albite, burnt Talc 10.12%, zirconium silicate 7.16%, zinc oxide 4.68% and barium carbonate 10.33%.

[0023] When preparing the surface glaze, it is necessary to mix the above weight percentages with various materials and put them into the ball mill for crushing. Thickness, and a total of 1560kg of water needs to be added during the ball milling process to improve the ball milling efficiency. The final surface glaze: the specific gravity is 1.80-1.83, the flow rate is 45s-65s, and the sieve allowance is 0.3-0.5.

[0024] If the total weight of various raw materials is 4000kg, in terms of weight percentage, the underglaze includes the following effective components: 24.24% of quartz sand, 9.16% of air knife soil, 6.68% o...

Abstract

The invention discloses a subdued light glaze for a thin ceramic plate. The subdued light glaze comprises a surface glaze and a ground glaze, wherein the surface glaze comprises the following effective constitution components in percentage by weight: 18-22% of high-temperature matte frit, 8-12% of Qidao clay, 14-18% of calcite, 19-23% of albite, 9-12% of calcined talc, 5-9% of zirconium silicate,3-6% of zinc oxide and 9-12% of barium carbonate; and the ground glaze comprises the following effective constitution components in percentage by weight: 22-26% of quartz sand, 8-11% of Qidao clay, 5-8% of ball clay, 7-11% of calcined talc, 13-16% of albite, 10-14% of nepheline powder, 8-12% of zirconium silicate and 11-15% of calcined kaolin. The sintering temperature of the subdued light glaze for the thin ceramic plate is 1180-1200 DEG C, the sintering cycle is 60-65 minutes, and the heat preservation time is 15 minutes. The subdued light glaze has relatively gentle glossiness, the glossiness of the subdued light glaze is generally within 30-60 degrees, and the glossiness relatively well meets a comfortable human view range. Due to the subdued light glaze disclosed by the invention on the thin ceramic plate blank, the surface of the thin ceramic plate blank can be smooth and fine, very gentle and free of light pollution, and a very good decoration effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of glazes for thin ceramic plates, and in particular relates to a soft glaze used in thin ceramic plates. Background technique [0002] Ceramic sheet is a plate-shaped ceramic product made of kaolin clay and other inorganic non-metallic materials through forming and calcination at a high temperature of 1200 degrees. With the development of economy and technology, the market demand for large-size ceramic tiles is increasing. Traditional technology and equipment are difficult to meet production needs. Ordinary ceramic tiles are a serious waste of resources, high energy consumption, heavy building loads, high transportation and construction costs. [0003] Unglazed products usually have defects such as rough surface, easy pollution, easy moisture absorption, easy erosion and so on. And the ceramic thin plate is used as decoration, it is very necessary to apply glaze on the embryo body. But the performance o...
