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?
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: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: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
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:Mullite bricks on alumina alumina is what?
Quality solutionsMullite brick:With mullite as main crystalline phase of high alumina refractory products. Mullite bricks containing Al2O3 64%~75%, refractoriness >1790? C, normal temperature compressive strength 70~260MPa, softening the starting point for 1600~1700 degrees. The manufacturing method for casting and sintering process.
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?
The floor tiles are not made exclusively of alumina. Pure alumina ceramics are expensive.
