Mo Laishi brick is the aluminous silicon that gives priority to brilliant photograph with Molaishi fireproof product. Mo Laishi brick as a result of its main brilliant photograph is Molaishi, its property basically depends on Molaishi. Fireproof function of Mo Laishi is in 1850 the left and right sides, suffer bear bate temperature tall, high temperature creep is small, shake sex is good, fight acid slag corrode.
Mo Laishi brick is to point to the expensive aluminous fireproof stuff that gives priority to brilliant photograph with Molaishi. General alumina content is between 65%~75% . Besides Molaishi, low alumina also is contained in mineral composition a few vitreous photograph and Fang Shiying, the person of tall alumina also contains a few corundum. Basically use at furnace of splitting decomposition of sintering furnace of regenerator of furnace of kiln of shaft of hot-blast stove coping, high temperature, glass, pottery and porcelain, oil to wait without blind angle lining.
Mo Laishi brick is fireproof the gender is tall, can amount to 1790 ℃ above. Load bate begins temperature to be 1600~1700 ℃ . Intensity of normal temperature compression is 70~260MPa. Heatproof shake performance is good. Have agglomeration Mo Laishi brick and electric frit Mo Laishi brick two kinds. It is main raw material with tall aluminous aluminous grog, join a few clay or unripe alumina to serve as bond, fire not comes stone brick. Electric frit not comes stone brick is raw material with alumina of tall alumina, industry and saggar, join charcoal or coke grain to serve as reducer, legal system of reductive report frit is used to build after shaping. Mo Laishi's crystallization is bigger than agglomeration Mo Laishi, it is good that its fight thermal shock sex at agglomeration goods. Its high temperature capability basically depends on of alumina content and Mo Laishi photograph and glass distributing equably.
How much is the coefficient of thermal conductivity of Mo Laishi firebrick? The coefficient of thermal conductivity of Mo Laishi firebrick is a respect only, according to each index, coefficient of thermal conductivity is (1000 ℃ ) W/m.k.0. Face 6-1.0.
Mo Laishi pledges the brick pledges Mo Laishi brick calls Molaishi adiabatic firebrick again gently gently, basically be the fireproof material that gives priority to mine photograph with siliceous aluminium, performance is superior (especially) of function of high temperature creep. The characteristic of light qualitative Mo Laizhuan: Low heat conduction, low thermal capacitance. 2. Purity is tall, matter content is low. 3. High temperature resistant, can contact blaze directly. 4. Intensity is high, heatproof shake performance is superior. But, because Molaishi is mineral exiguous, pass synthesis only, ability of complex Mo Laishi issues the stabilizes exclusively compound in forming a system in constant temperature -- Mo Laishi crystal. AL203 composition of Mo Laishi is about 79% , SI02 suits more 21% , but there is a certain quantity of foreign matter part in raw material, part can be reflected below high temperature. Accordingly, as the addition of foreign matter composition, the content of glass and corundum can increase, mo Laishi can form structure of thick any crystalline substance, raise the hole rate of the product thereby, reduce the stability of thermal shock and corrosion resistance, easy craze.
Mo Laishi brick contains foreign matter oxide normally, be like TiO2.Fe2O3.CaO.MgO.K2O and Na2O. The prep above of Mo Laishi matter content that natural raw material produces synthesizes raw material. Accordingly, mo Laishi has agglomeration law and electric frit way technology of two kinds of production. Synthesis not comes alumina of Shi You industry, hydroted alumina, pure clay (kaolin of small foreign matter) make with Xie Lashi, also add clay to be made by tall bauxite, or straight joint makes brick of Mo Laishi heat preservation into Molaishi. The light qualitative Molaishi that gives priority to brilliant photograph with Molaishi brick. Outside dividing Molaishi, contain the mineral composition with inferior alumina to still contain a few glass photographs and Fang Shiying; Contain alumina taller still contain a few corundum, fireproof sex is taller.
