Problems solved by technology

[0002] Porcelain has a long history in our country. Its production is made of porcelain stone, kaolin, quartz stone and mullite after high-temperature firing. Because of its excellent performance, it has been widely used in all walks of life. At present Existing porcelain production is fired at high temperature, and due to the composition of the raw materials of the porcelain itself, the existing architectural porcelain has many disadvantages, such as complicated preparation process and high firing temperature, which leads to a lot of waste of energy, and firing The quality of porcelain products is not ideal, the strength and hardness are relatively low, and they are easy to be damaged. Therefore, a large number of damages occur during transportation and use, which not only leads to high costs in various links, but also causes waste of energy.
[0003] Matte glaze is a kind of special glaze between glossy glaze and matte glaze. After the material is melted at high temperature, a part of the glaze component is separated into crystals during the cooling process. The existing matt glaze has complex components, and the firing time is long, the firing temperature is high, and the production requires more fuel. Production Relatively low efficiency and high production cost
