Light Weight Mullite Insulation Brick can be widely used for lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry.Application:
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite
- 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?
- Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
- 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 refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of space, and good insulation effect
- 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 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?
- Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
