Data of technology of heat preservation brick closes market

Heat preservation brick is one of commonly used insulation material that furnace of high temperature kiln realizes energy-saving environmental protection,


Heat preservation brick has a lot of kinds, if brick of light qualitative clay, tall aluminium gets together,brick of heat preservation of light brick, light qualitative silica brick, diatomite, Molaishi gets together light brick (JM series) alumina is hollow hollow ball brick waits ball brick, zirconia a moment.
How many does heat preservation brick have one ton? The mark brick with 0.6 secret system (230*114*65mm) sheet weighs 1 kilogram, one ton has 1000, the sheet with 0.8 secret system weighs 1.36 kilograms, one ton has 735, 1 system are secret, sheet weighs 1.7 kilograms, one ton has 588.
1, the adiabatic and refractory products of the Al2O3 content 30%-48% that brick of heat preservation of clay of brick of argillaceous heat preservation makes for main raw material with fireproof clay 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. The manufacturing technology with commonly used brick of argillaceous heat preservation is to add float bead burn ashes to add content way, also can use bubble law technology.
The Al2O3 content that brick of light qualitative tall aluminous heat preservation pledges brick of tall aluminous heat preservation is main raw material to be made with aluminous alumina gently is not less than the adiabatic firebrick of 48 ％ . Tall aluminous qualitative adiabatic firebrick, basically use aluminous aluminous grog, combinative clay makes raw material, mix into is mixed into bond curium wood chip, to improve product performance, add the fine pink of stone of line of industrial alumina, corundum, silicon, cyanite, silica. Can make the product that gets above of Cm3 of ／ of bulk density 0.4g. Al2O3 content and bulk density are different, limitation uses temperature to also differ, be in normally 1350 ℃ of 1250 ～ , some can amount to 1550 ℃ . About the price of brick of light qualitative tall aluminous heat preservation, main influencing factor has the dimension of light qualitative tall aluminous brick, amount and manage to change target.
Pledge this product uses diatomite brick gently the light qualitative brick that poriferous shape diatomite makes for raw material. Natural diatomite is alga what form after organic material is corrupt is loose and poriferous mineral, bases is 2: Oxidation silicon (95 ％ of 73 ％ ～ ) , have good and adiabatic property. A few union clay and combustible are joined in diatomite, classics embellish is wet mix. Shape and firing, make different appearance products. Cent of complex miscellaneous degree is case appearance mark, general, different and special model, by bulk density cent is 6 kinds. Bulk density limits: 1 ／ of 0.4 ～ Cm3, coefficient of thermal conductivity is 300 ℃ M.K of ／ of 0.13 ～ 0.21w, intensity of normal temperature compression 0.6 ～ 2.5MPa, fireproof temperature amounts to 1280 ℃ , limitation uses temperature 1000 ℃ of 900 ～ . Use as the heat insolation of facilities of industrial kiln furnace, hot project and conduit, insulation material.
Light qualitative silica brick pledges brick of light qualitative clay cannot be likened to silica brick gently. Porosity makes an appointment with the light qualitative silica brick of 50% , rate of its heat conduction is minorrer than brick of light qualitative clay. The loading of light qualitative silica brick is out of shape temperature amounts to 1620 one 1640 ℃ , and brick of light qualitative clay has 1200 only, 1300 ℃ , do not contract below high temperature. Expand instead at 1450 ℃ (0.2%) agreement ＜ , volume is steady, and clay pledges the brick contracts gently big, make lining annihilate is cracked easily. By a lot of concrete example prooves, light qualitative silica brick is OK the furnace kiln that works below 1550~1600 ℃ temperature is used for a long time; And but the hot side that immediate step enrages at contacting furnace, also can use at the roof of big span; In the high temperature that cannot use brick of light qualitative clay the place can use light qualitative silica brick. Light qualitative silica brick is used in heating furnace lining, with use brick of light qualitative clay to compare, can shorten heat period, reduce the amount of specific fuel consumption of 35 ％ . In firing kiln (kiln pouring blaze) kiln top uses light qualitative silica brick, can prolong the service life of roof.
Mo Laishi pledges Mo Laishi of heat preservation brick pledges heat preservation brick is the adiabatic and fireproof product that makes for main raw material with Molaishi gently gently. Mo Laishi pledges gently heat preservation brick high temperature resistant, intensity tall, thermal conductance is low, can contact blaze directly, apply to the liner of all sorts of industrial furnace kiln. The tall aluminium that gives priority to brilliant photograph with Molaishi pledges we weigh fireproof material pledge gently for Molaishi heat preservation brick. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; Contain alumina taller person still contain a few corundum. Low heat conduction is led, have effect of very good adiabatic heat preservation; Fireproof degree tall; The higher volume that contain aluminium makes its still maintain good performance below reducing atmosphere; Intensity of hot condition compression is high.
Hollow ball brick fights alumina flake hollow ball brick uses alumina hollow ball is alumina main raw material, high-powered small pink is additive, organic material is done temporarily bond, become in fire of the high temperature inside shuttle type kiln. Many closed pore is contained inside goods, have qualitative light performance of high temperature resistant, heat preservation is good, burn systole again small, heatproof shake performance is good wait for a characteristic, mix to aggressivity gas slaggy also have stronger counteractive capacity. Products can increase kiln furnace thermal efficiency to use greatly, shorten production is periodic, reduce kiln body weight, implementation is energy-saving fall bad news. Goods of hollow ball brick can contact alumina directly blaze, apply to the liner of furnace of kiln of splitting decomposition furnace, hot-blast stove, heating furnace, channel, ejector plate kiln, crucible and kiln of all sorts of electric stove, report, gold of wide application Yu Ye, be able to bear or endure the industry such as material, light industrial, chemical industry, pottery and porcelain, glass, electron.
Zirconia is hollow ball brick zirconia is hollow ball brick is superhigh temperature energy-saving model small qualitative particular kind is fireproof material zirconia is hollow ball brick goods is one kind can be in the superhigh temperature of 1800-2400 ℃ is energy-saving model small qualitative particular kind is fireproof material. Because the thermal conductance of this kind of goods is 0.3-0.4W/ (M·k)- zirconia is hollow ball brick is to use electric frit law to blow make zirconia hollow ball, in zirconia bond is added in hollow ball, the course shapes and firing the zirconia that makes is hollow ball brick goods. Hollow ball brick has this zirconia purity is tall (≥99% of content of ZrO2+ stabilizing agent) , high temperature resistant (use temperature can achieve 2200 ℃ ) adiabatic function is good, chemical stability is excellent characteristic, liner of the heat of intermediate frequency induction that basically is used at hard alloy, melt quartz furnace and operation temperature are in the superhigh temperature equipment of 2000 ℃ above works liner or adiabatic line.
