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: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: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: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:The introduction of mullite brick
High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.
Q:Mullite bricks on 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: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: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 difference between mullite ceramics and alumina ceramics? Can you tell me something to do with floor tiles?
Mullite is formed by the reaction of alumina with silica. The main difference between him and alumina is that:Hardness: alumina is harder than mullite, but two are tough enough, and are not easy to break.Corrosion resistance: mullite acid is not alkali resistant. Alpha alumina ceramic acid, alkali resistance - for floor tiles, alumina corrosion resistance is too high, unnecessary.
