DESCRIPTION OF PRODUCTION

 CCEFIRE Mullite Insulating Fire Brick is made from high-grade, high purity refractory materials by mixing, press-forming, drying, sintering and

machining. Good process providing excellent heat insulation at high temperature and offers genuine energy savings.It offers a combination of

insulating properties with load bearing ability. CCEFIRE mullite insulating fire brick are suited to applications above 1000°C or 1832°F and

particularly suited to highest temperature applications above 1600°C or 2800°F.

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
If there is no mark, ask the laboratory of the production factory to analyze any chemical or physical items. Or, check the national standard, the national standard has the basic requirements of the physical indicators
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: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 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?
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
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: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: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.
