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
Different refractory materials have different requirements, specific industry or national standards, such as LZ can check the mullite bricks GB / standard, there should be a harvest, do testing project is in accordance with the requirements of the LZ need to determine the use requirements
Q:What are the varieties of polycrystalline mullite?
PNF-100 seriesThe PNF-100 series are made of polycrystalline mullite fiber cotton felt to cut, compress, and wrap into blocks without any adhesive.Characteristic: thermal shock resistancelow thermal conductivityLight weightSound absorption propertyLow thermal storage
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: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
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:The introduction of mullite brick
High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.
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: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 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 difference between mullite ceramics and alumina ceramics? Can you tell me something to do with floor tiles?
Corrosion resistance: mullite acid is not alkali resistant. Alpha alumina ceramic acid, alkali resistance - for floor tiles, alumina corrosion resistance is too high, unnecessary.Sintering temperature: the sintering temperature of mullite is low. So the cost is low because of this, so alumina ceramic is basically not used for floor tiles - unless it's too rich to burn.Heat shock resistance: the thermal shock resistance of mullite is higher than that of alumina.High temperature creep properties: the high temperature creep of mullite is higher than that of alumina, so mullite can bear higher weight at high temperature, and alumina is less.Resistance: alumina ceramic resistor is higher than mullite, so it is used as high-voltage insulators.
