Problems solved by technology

Traditional bakeware ceramic products have poor thermal stability, and are easy to crack when heated and cooled rapidly, so they cannot be dry-fired
At present, the heat exchange value of this kind of product is about 20-180°C. After dry burning over 180°C, it will crack when it is quenched. Since the firing temperature of this kind of product is basically between 1160-1230°C, the high firing temperature causes its color to be monotonous. Decorative and ornamental are poor
[0004] Chinese patent publication CN1230528A discloses a ceramic material composition, which is to add three-dimensional four-needle zinc oxide whiskers to the ceramic formula to improve the quenching resistance and quenching resistance of the ceramic material, but in order to make the three-dimensional four-needle zinc oxide whiskers It must not be destroyed, the mixing and grinding process requires high requirements, it is difficult to control, and it does not contribute to the utilization of waste products
CN1155525A discloses a kind of ceramic material for heat-stable porcelain tableware, which mainly adds lepidolite into general ceramic material to realize the advantages of low me

Abstract

The invention discloses blank for preparing ceramic products such as baking pans, etc., relative glaze and the finished ceramic product. The blank comprises kaolin, talc, feldspar and limestone; in addition, the blank also comprises waste glass, the weight of which against the total weight of the blank is between 10 and 28 percent; the glaze comprises low-temperature clinker, feldspar, quartz and calcite; the blank is used to make the ceramic body, the surface of the ceramic body is coated with the glaze and burned at a temperature of between 1060 and 1150 DEG C, and the ceramic products such as baking pans, etc. can be obtained. The invention fully utilizes the waste glass, the burning temperature is low, the prepared ceramic product undergoes the quenching after being burned at a temperature of 280 DEG C and the quench cracking does not occur, and after the burning and the quenching, no fog dot exist on the glaze.

Description

technical field [0001] The invention relates to ceramic raw materials and ceramic products thereof, in particular to blanks for manufacturing bakeware ceramic products, corresponding glazes and the prepared bakeware ceramic products. Background technique [0002] Under the new situation with increasing requirements for energy conservation and environmental protection, higher requirements are put forward for the daily-use ceramics industry. If the daily-use ceramics industry is to move towards sustainable development, enterprises must achieve energy conservation and emission reduction, and products are economical and environmentally friendly. Improve market competitiveness. In order to develop, enterprises should intensify scientific research, carry out technological innovation, and strive for greater breakthroughs in production. [0003] Suitable for use in microwave ovens and ovens, as well as bakeware ceramic products that can be mechanically washed, it is required to hav...
