Introduction of basic parameters and ingredients of light mullite brick
May 17, 2022
In addition to mullite Brick, the mineral composition contains a small amount of vitreous phase and cristobalite with a lower alumina content; a small amount of corundum is also contained in the higher alumina content. Lightweight mullite bricks use imported tabular corundum and high-purity fused corundum as the main raw materials, and apply advanced superfine powder adding technology. After mixing, drying, and molding, they are fired in a high-temperature shuttle kiln. The dimensions, physical and chemical indicators, and service life of the products all meet the requirements of customers.
Good thermal shock resistance. There are two types of sintered mullite bricks and fused mullite bricks. Their high-temperature performance is mainly determined by the alumina content and the homogeneity of the mullite phase and glass distribution.
Lightweight mullite brick ingredients
The production of lightweight mullite brick uses sawdust, styrofoam pellets, and their mixtures as an additive to ash, respectively. The ingredients are made according to the formula. When ingredients are added, firstly add the clinker, industrial alumina, and kaolin to the mixing tank for dry mixing for 2-3 minutes, then add additives and binders (additional), stir while adding, and mix well. It can be used after 24 hours of sleepiness.
