The Specification of Mullite Lightweight Brick

Mullite lightweight brick is made from natural raw materials, low iron high alumina, mullite crystal structure to phase-based high-quality insulating firebrick.
Selection of high purity refractory powders, according to the proportion of products required to join the organic compound filler, vacuum compression molding, high temperature sintered mullite lightweight products.
Energy efficiency, high strength, good thermal shock resistance, low thermal conductivity, resistance to penetration ability, resistance to erosion is an ideal long-life product.
The product can be widely used in metallurgy, petrochemical, machinery, ceramics and other industries, for industrial furnace lining or insulation.

Manufacture Low Apparent Porosity Mullite Insulating Fire Brick for Heating Furnace

Q:What is the price of refractory bricks?: The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material

Q:The introduction of mullite brick: General alumina content in 65% ~ 75% between. In addition to mullite, the mineral composition contains lower amounts of glass phase and square quartz, and alumina containing a small amount of corundum.

Q:Aluminum content 38, silicon content 55 What refractory bricks?: The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3.

Q:The difference between the high aluminum corundum brick and corundum mullite brick: Tiles are called floor tiles, floor tiles, polished tiles and glazed tiles are glazed tiles, bricks are samples of all kinds of tiles, ceramic tiles will be placed in the tile shop, tiles are also divided into outer wall tiles and inner wall tiles, modern brick and antique brick

Q:What are the properties of corundum mullite?: Lightweight materials have uniform internal structure, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature and low thermal conductivity.

Q:(refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you: Is there a mark on the contract? Mark the items as required by the contract.

Q:Jm26 mullite aluminum content in the number, ask God to answer. 23 more. How is this identified with the naked eye?: Under strong alkaline conditions, aluminum is separated from other metal ions by the amphoteric nature of aluminum.

Q:Mullite bricks in alumina alumina is what?: Mullite (3Al2O3 - 2SiO2) high alumina refractory materials as the main crystal phase. The general alumina content in 65% ~ 75%. In addition to mineral composition of mullite, alumina containing low also contain a small amount of glass phase and cristobalite; alumina containing high also contain a small amount of corundum.

Q:Mullite brick: Mainly used for hot blast stove of blast furnace and furnace bottom and furnace, glass furnace regenerator, sintering kiln, petroleum cracking dead lining system.

Q:Refractory bricks (mullite bricks) can be used on the walls of buildings?: Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
