In fireproof data products, pledge the composition of Mo Laishi brick is alumina gently, brilliant elephant is Mo Laishi photograph, mo Laishi goods has favorable heatproof shock effect, light simple product has favorable heat preservation effect.
Fireproof material the inorganic metalloid material with 1580 ℃ fireproof above. Fighting bad temper is to show fireproof material is in without loading, high temperature resistant the action, temperature that does not arise after bate melt and melt is centigrade. Shaping refractory products. Commonly used and common finalize the design refractory products (firebrick) brick of silica brick, half silica brick, clay, tall aluminous brick, magnesia brick waits; Commonly used and special material has AZS brick, corundum brick, direct couple magnesian chromic brick, carborundum brick, nitrogen changes silicon and silica brick to wait. Adventitious refractory products is tasted originally for the mixture that bond or fireproof collect makings, pink makings, other sophisticate makings comprise by certain proportion, can use directly, in also can joining proper liquid, allocate. Blame figuration is fireproof material is a kind new-style do not require calcination, fireproof level not the fireproof material under 1580 ℃ .
Pledge Mo Laishi brick uses Molaishi to give priority to brilliant photograph and combinative be apart to heat up fireproof material gently, it is main raw material with tall aluminous aluminous grog, add makings of high quality high pure and fireproof pink, by the product requirement scale joins organic and compound filling, pouring shape, high temperature fire not comes gently character rock products.
Because Molaishi is mineral exiguous, rely on artificial synthesis only so, complex Mo Laishi mixes by certain proportion, can form the stable compound in the system below constant temperature, not come namely stone crystal. Compositive AL203 of Mo Laishi is about 79% , SI02 is about 21% , but a certain quantity of impurity is contained in raw material, the reaction of constituent is caused in the meeting below high temperature, foreign matter constituent is so more, glassy jump over with corundum content much, mo Laishi forms structure of thick any crystalline substance, bring about goods porosity to increase, thermal shock stability drops with the sex that fight corrode, easy generation is interstitial. Accordingly, manufacturing technology cent of Mo Laishi is two kinds: Agglomeration craft and electric frit craft. With industrial alumina, hydroted alumina and pure clay (the kaolin of small foreign matter) reach Xie Lashi to wait for raw material, it is raw material with tall aluminous alumina, it is binder with tall aluminous alumina, or synthesize Molaishi with tall aluminous alumina directly, produce brick of Mo Laishi heat preservation to wait for a product. A kind of light qualitative Molaishi brick, give priority to brilliant photograph with Molaishi. Mineral in outside dividing Molaishi, alumina content is low mineral in still contain a few vitreous photograph and Fang Shiying; Content is high mineral in contain a few corundum, and fireproof sex is good.
The mechanical function that pledges the function high temperature of Mo Laishi brick falls gently and good stability. Rate of high temperature creep is inferior, coefficient of expansion is lesser; Heatproof shake sex is good; Fight chemistry to corrode ability strong; 5 it is managing the sources of energy.
Pledge the use note of Mo Laishi brick pledges the brick chooses Molaishi gently gently natural material of tall aluminous low iron, the adiabatic firebrick that the structure gives priority to with photograph of Mo Laishi brilliant, have compression strength tall, thermal stability is good, coefficient of thermal conductivity is low, impervious capability is strong, be able to bear or endure erode, can use extensively at the industry such as metallurgy, petrifaction, mechanical, pottery and porcelain, make the liner of industrial furnace kiln or thermal insulation, it is long life, energy-saving good product. Can ask to increase Mu Fenhe to get together according to the user benzene spherule, production gets together brick of heat preservation of light Mo Laishi. Attention: 1. Classification temperature is to show fireproof material heats to contract to the line the 2% temperature when, unfavorable as the basis that chooses temperature. 2, when with light qualitative Molaishi the brick is fireproof working face, the high temperature inside kiln is a when decide to choose sort of light simple fireproof stuff main factor, place choosing not comes gently character the working temperature of stone brick should inside prep above kiln ℃ of 100-300 of real work temperature. The choice pledges the type of Mo Laishi brick consults please gently index of bate of its to load. 4, bulk density and the quantity that contain aluminium can ask to adjust according to the user.
Fireproof material pledges composition of Mo Laishi brick is in fireproof data products gently, pledge the composition of Mo Laishi brick is alumina gently, brilliant elephant is Mo Laishi photograph, mo Laishi goods has favorable heatproof shock effect, light simple product has favorable heat preservation effect.
Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
