Mullite Insulation Brick can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much
- 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: (refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you
- Compressive strength, volume density, flexural strength, thermal shock resistance, high temperature load, creep temperature, refractoriness, etc.. There should be GB
- 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: 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.
- 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: Jm26 mullite aluminum content in the number, ask God to answer. 23 more. How is this identified with the naked eye?
- In the presence of excess EDTA in the acidic medium, the aluminum is complexed with EDTA, and the remaining EDTA is complexed with lead salt, and then the EDTA complexed with aluminum is replaced by sodium fluoride, and the lead salt is substituted...
- Q: Mullite brick
- High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase. 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: 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: Refractory bricks (mullite bricks) can be used on the walls of buildings?
- In many architectural design, high-rise fire rating is placed in the important position of the topic, especially when the floor height is more than 20 layers, we have more stringent requirements for the choice of fire resistant materials. The building wall, kitchen flue, boiler flue, flammable zone must use a firewall barrier, in many refractory refractory brick is the product of choice for fire resistance of refractory brick masonry is more stable.
