Light qualitative adiabatic brick has brick of argillaceous heat preservation, tall aluminium to get together light, Molaishi gets together hollow ball brick waits light brick and alumina a moment.
Alumina pledges adiabatic firebrick produces firebrick of craft alumina heat insolation is alumina of corundum of the frit that use phone, agglomeration and industrial alumina have for what main raw material makes acid-proof alkaline atmosphere and fight fulfiling one's promise ability strong, fight goods of firebrick of good heat insolation of thermal shock sex, its produce craft to bubble law and burn oneself out add thing two kinds.
One, raw material and additive. It is main raw material with alumina of electric frit corundum, agglomeration and industrial alumina, add thing for burn oneself out with polystyrene spherule, silica or other material make bulk stabilizing agent, normal temperature, high temperature all has combinative effect, accretion is bond. 2, burden, mix drill and shape. Density of volume of burden basis product and its manage change function requirement, decide the affiliation of of all kinds stock is measured. Mix practice to use the machine that mix practice or slip mixer, order of feed in raw material is: Bond of part of polystyrene spherule → and bond of → of makings of water → pink. Shape use product measure to master easily, the vibration that produces spring back not easily shapes reach its other means to shape, or use slop pouring shape. 3, dry and firing. Dry when, because polystyrene spherule is in 110 ℃ of 90 ～ bulk leap, ever since namely liquefacient, vaporization, oxidation disappears, after most manufacturer undertakes to polystyrene spherule Peng changes processing reoccupy at production, so dry temperature shoulds not be exorbitant and previous, dry the adobe remains moisture after asks to be less than 2% . Loading of kiln uses side code, firing when the volume that microtherm phase should note to burn lost property changes, the bulk density that depends on goods and manage change index to decide upper limit is firing temperature, want to be more than 1600 ℃ commonly, can compare compact brick firing the system is a few faster. Firebrick of alumina heat insolation can use as the working layer that contacts blaze directly or use as thermal insulation. Use extensively at pottery and porcelain, fireproof material firing component of sintering furnace of kiln, pulverous metallurgy, semiconductor is firing kiln and have hydric the kiln furnace with reducing atmosphere. Because this is planted,the norms of firebrick and dimension also are to have a lot of kinds, so proposal client must be cleared up when purchase is general firebrick or different firebrick,
Tall aluminium gets together light brick tall aluminium gets together light firebrick uses tall aluminous aluminous grog to add a few clay, law or bubble law produce with gas after classics mill with slop form pouring, figuration, via 1300 ～ 1500 ℃ are firing. Also can replace partial alumina grog with industrial alumina sometimes. With the liner that builds kiln furnace at build by laying bricks or stones and thermal insulation, and erode without stock of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, temperature of watch surface contact does not get prep above 1350 ℃ .
Mo Laishi gets together light brick is brick of a kind of light qualitative heat preservation, also call Molaishi heat preservation brick, have effect of favorable heat preservation heat insolation, system is secret little weight is light also be its characteristic, add expander production to come out, can get used to the shuttle type kiln with higher temperature. 2, shape handiwork instead machine is pressed shape, can increase strength. 3, the product that produces manufacturing unit weight 0.8g/cm3 by machine pressing means, its coefficient of thermal conductivity and intensity value show this product adequately as kiln furnace energy-saving liner brick has development outlook. Get together in Molaishi in brick of light heat preservation, because joined the Molaishi of certain amount and oxidation aluminium powder, make Molaishi gets together brick of light heat preservation is fireproof degree tall, thermal shock stability is good, can get used to temperature of shuttle type kiln completely to fluctuate.
The adiabatic and refractory products of 30%-48% of content of Al2O3 of brick of argillaceous heat preservation 5 use fireproof clay, float bead, fireproof clay grog makes raw material, mix into is added bond and curium wood chip classics cooperates, mix, shape, dry, firing, can make the product that gets bulk density 0.3~1.5g/cm3, output occupies above of half of heat preservation brick.
