Problems solved by technology

However, saggars, as containers for holding materials, are still widely used in ceramic pigment enterprises. In recent years, due to the rising costs of raw materials, fuel, labor, etc., the price of saggars has also increased significantly. The service life is decreasing, and the breakage rate of saggers is 16-22% per kiln, causing serious waste of resources and economic losses

Abstract

The invention relates to a preparation method of a composite sagger. The method adopts mullite and cordierite as the main raw materials, takes attapulgite, calcined kaolin, diopside, fused magnesia, red mud, nano aluminum hydroxide sol, silica powder and reinforced fiber as auxiliary materials, at the same time in the preparation process, water quenching, oil cooling and post-treatment processes are employed to improve the physicochemical properties of the product, the prepared sagger has good thermal stability, strong compressive strength, corrosion resistance, and difficult cracking.

Description

technical field [0001] The invention belongs to the field of refractory saggers, in particular to a preparation method of a composite sagger. Background technique [0002] The sagger is one of the kiln furniture. In the process of firing ceramics, in order to prevent gas and harmful substances from damaging and fouling the body and glaze, the ceramics and body are placed in a container made of refractory material and fired. This container is called a sagger. , also known as the casket. [0003] The use of saggers to fire ceramics can not only increase the amount of firing, prevent the products from sticking, and increase the yield of finished products, but also has certain thermal conductivity and thermal stability, which can ensure the quality of ceramics. The shape of the sagger varies according to the shape of the utensil. The eggshell black pottery fired during the Longshan culture period in our country has already used a special sagger. Two saggers made of eggshell ...
