》The foam method is to mix the foaming agent with the stabilizer and water in a certain proportion, first make the foam liquid, then mix it with the slurry, and then process the molding, curing, drying, baking and firing to make high Lightweight mullite turn with porosity. Although it is possible to produce high-quality products, there are many procedures, the production process is more complicated, and the production cycle is long, the production efficiency is low, and the production cost is high.
》The production of mullite bricks by gasification method refers to the introduction of substances that can play a chemical role to produce gas in the ingredients, and the use of chemical methods to obtain bubbles, so as to produce bricks with high porosity and low density, and the cost is high. But it is rarely used in actual production.
》The additive burn-out method to produce mullite bricks is to add some combustible additives to the ingredients, such as wood chips, polystyrene, coke, etc. When the brick is fired, the combustible additives burn rapidly, and the position of the additives is The stomata. This kind of brick with high porosity and low density becomes mullite brick. This method has simple production process, short production cycle and low cost, so the production efficiency is high.
High refractoriness: Mullite bricks have a refractoriness of up to 1750°C (3182°F). This means that they can withstand very high temperatures without melting or softening.
Strong resistance to chemical attack: Mullite bricks are resistant to attack by a wide variety of chemicals, including acids, alkalis, and salts. This makes them a good choice for use in applications where the bricks will be exposed to harsh chemical environments.
Good thermal shock resistance
Mullite bricks are resistant to thermal shock. This means that they can withstand rapid changes in temperature without cracking or spalling.
Low thermal conductivity
Mullite bricks have low thermal conductivity. This means that they do not conduct heat well, which helps to keep the heat inside the furnace or kiln.
Good dimensional stability
Mullite bricks have good dimensional stability. This means that they do not change shape or size significantly when exposed to high temperatures.
Applications of Mullite Brick
Glass furnaces
Mullite bricks are used in the lining of glass furnaces. They are used to protect the furnace walls from the high temperatures and corrosive melts that are produced during the glassmaking process.
01
Cement kilns
Mullite bricks are used in the lining of cement kilns. They are used to protect the kiln walls from the high temperatures and corrosive gases that are produced during the cementmaking process.
02
Steel furnaces
Mullite bricks are used in the lining of steel furnaces. They are used to protect the furnace walls from the high temperatures and corrosive slags that are produced during the steelmaking process.
03
Incinerators
Mullite bricks are used in the lining of incinerators. They are used to protect the incinerator walls from the high temperatures and corrosive gases that are produced during the incineration process.
04
Other applications
Mullite bricks are also used in a variety of other applications, such as petrochemical furnaces, ceramic kilns, and heat treatment furnaces.
