There are three methods of producing light -quality Mullite Block: bubble method, additive sintering method and gasification method.
Make lightweight Mullite Block with a bubble method to make foaming agents, stabilizers and water in a certain proportion, first make foam solution, and then mix the slurry and pour it. The process is made of lightweight mullite brick with a high pore rate. Although it can produce high -quality lightweight mullite, its procedures, complicated, long production cycle, low production efficiency, and high Chenben.
The additive Mullite Block is added to the ingredients, such as wood chips, polystyrene, coke, etc. In the ingredients pole, this brick with high pores and small density becomes lightweight mullite bricks. This method has a simple production process, short production cycle, low cost, and high production efficiency.
The production of light -quality Mullite Block in gasification method refers to the introduction of substances that can produce chemical effects in the ingredients. The chemical methods are used to obtain bubbles, which produces bricks with low pores and small density. This method is simpler than the bubble method, the production cycle is long, and the cost is high. It is rarely used in actual production.
According to the actual situation, some special refractory material factories can consider using additives to produce light -quality Mullite Block. The addition of the burn method to produce light -quality mullite bricks, there are three methods of forming: vibration, pouring, and hand -made formed. Vibration and molding production of lightweight mullite, short cycle, high production efficiency, but quality (especially density) is difficult to control; long watering molding cycle, low production efficiency, high cost (mold cost); hand -made formed production efficiency of production efficiency Low, low cost, high labor intensity, and difficult to control quality.
The above is a brief introduction to the “The producing of mullite bricks method”, which is for reference only.
