- Q:The introduction of mullite brick
- High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.
- 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
- If there is no mark, ask the laboratory of the production factory to analyze any chemical or physical items. Or, check the national standard, the national standard has the basic requirements of the physical indicators
- Q:Mullite brick
- High refractoriness, up to 1790 degrees celsius. The softening start temperature is 1600~1700 degrees. The compressive strength at normal temperature is 70 ~ 260MPa. Good thermal shock resistance. The sintered mullite and fused mullite brick two. Sintered mullite brick with high bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Fused mullite brick with high bauxite, alumina and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, formed by reduction of electric melting method to manufacture. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of the phase distribution of mullite and glass. [1]
- Q:What are the properties of corundum mullite?
- Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
- Q:Refractory bricks (mullite bricks) can be used on the walls of buildings?
- Refractory bricks used in the firewall, the first choice of national standard model, its size is 230mmx114mmx65mm, model T-3, component 3.5-3.7kg, and sometimes will use refractory bricks, seven separately to make up for the effect. Refractory brick in masonry usually fireclay, refractory soil adhesion is very strong, and has a certain degree of refractory refractory, so was widely used in refractory masonry, in building fire protection requirements if the fire rating is high, to the selection of refractory masonry cement, refractory cement refractoriness of fireclay than about 500 DEG C high.
- 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 difference between the high aluminum corundum brick and corundum mullite brick
- Wall tiles and floor tiles are collectively referred to as ceramic tile flooring
- Q:What are the varieties of polycrystalline mullite?
- PMF (polycrystalline mullite fiber) is an international super light resistant high temperature heat insulation material of the latest, it consists of mullite micro crystal which integrates crystal and fiber materials properties in one, has an excellent thermal stability, temperature 1500, melting point 1840, the thermal conductivity of refractory brick is a traditional 1/6, bulk only the 1/25 is the ideal material for high temperature furnace energy saving.
- 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:Aluminum content 38, silicon content 55 What refractory bricks?
- When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
