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 discloses a composite saggar and a preparation method thereof. The composite saggar is prepared from raw materials in parts by weight as follows: 10-13 parts of magnesium mud, 10-12 parts of black talc, 33-35 parts of refractory mortar, 10-12 parts of sand, 4-6 parts of ballstone, 4-6 parts of aluminum powder, 5-7 parts of bauxite, 17-19 parts of refined mud, 90-160 parts of mullite, 22-35 parts of cordierite powder, 8-12 parts of attapulgite, 8-12 parts of calcined kaolin, 8-12 parts of diopside, 1-8 parts of fused magnesite, 1-3 parts of red mud, 1-3 parts of nano aluminum hydroxide sol, 1-3 parts of silica powder and 1-3 parts of reinforced fiber. The thermal stability, compressive capacity, corrosion resistance, low cracking probability and other properties of the saggar are improved by optimizing the raw material composition of the saggar, so that the saggar has the advantages of long service life and light mass. The adopted raw materials are cheap, and the preparation technology is simple, green and environment-friendly and can be industrially implemented.

Description

technical field [0001] The invention belongs to the field of refractory saggers, in particular to a composite sagger and a preparation method thereof. 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 ...
