There are three ways producing light mullite brick at home and abroad: foam method, additive burn method, gasification method. The use of foam to produce light mullite to the blowing agent and stabilizer and water according to a certain proportion of the first made of foam liquid, and then mixed with the slurry by casting molding, curing, drying, baking and firing And other processes, made of high porosity of light mullite turn. Although it can produce high-quality light mullite turn, but its process procedures, more complex, long production cycle, low production efficiency, high cost.
In addition, the combustible additive is rapidly combusted, and the position of the additive becomes a place where the combustible additive is added to the ingredients. Stomata. This porosity is high, the density of small brick has become a light mullite brick. The method of producing the process is simple, the production cycle is short, the cost is low, the production efficiency is high.
Gasification production of light mullite brick is introduced in the ingredients can play a chemical role in the production of gas substances, the use of chemical methods to obtain bubbles, resulting in high porosity, low density of brick, the higher cost, Actual production is rarely used.
