Heat preservation brick close, dimension concerns an a ton number and body, can have consideration through formula.
Brick of qualitative light heat preservation calls tall aluminous adiabatic brick, the qualitative light fireproof insulation material that ferric oxide content makes each other by Molaishi and sandwich glass photograph or corundum in 48% the left and right sides, keys. Cubage is opposite density 0.4 ～ 1.35g/cm3. Hole leads 66% ～ 73% , compression experiment compressive strength 1 ～ 8MPa. Heat-resisting shake performance is good. Brick of qualitative light heat preservation chooses tall aluminous aluminous grog to add grain clay commonly, classics mill is over to produce law or expanded plastics law to be irrigated with silty means with steam system build, shape, via 1300 ～ 1500 ℃ fire. Also can produce ferric oxide to replace grog of one part alumina with industry occasionally.
Li of line of furnace of kiln of wall of build by laying bricks or stones of in order to and thermal insulation board, reach its to fuse without apparently tall raw material is corroded reach the place that erodes effect. Instantly with flame lay a finger on when, of surface layer lay a finger on is spent cannot cross 1350 degrees high. In addition, clay brick wants with light clay (include the grain such as diabase, gangue brick to expect) for crucial raw material, classics pug is solved, figuration, dry impetuous and earth up burn and become, the content of clay brick Al2O3 that is in our country is in more commonly 40% the left and right sides, fe2O3 content under 2 ～ 2.5% . The grog in raw material is 65 ～ 85% , shirt-sleeve light clay is 35 ～ 15% . The grog of will broken shirt-sleeve light clay and mill is mixed grind, configure half dry pug together with grain content grog again, Zuo presses figuration, fire finishs in about 1400 ℃ , performance is good.
Heat preservation brick and firebrick key difference have the following content:
Of brick of heat preservation of function of 1. adiabatic heat preservation conduct heat coefficient is in commonly 0.2-0.4(average air temperature 25 ℃ of 350 ± ) W/m.k, and of firebrick conduct heat coefficient is in 1.0(average air temperature 25 ℃ of 350 ± ) W/m.k left and right sides, thereby but many the performance of adiabatic heat preservation that the function of adiabatic heat preservation of brick of cipher out heat preservation wants to compare firebrick is good.
2. is fireproof those who spend heat preservation brick is fireproof degree be in 1400 degrees commonly following, and of firebrick fireproof degree control in 1400 degrees.
Brick of heat preservation of 3. opposite density is heat-insulating material of qualitative light heat preservation completely commonly, opposite density is in commonly 0.8-1.0g/cm3, and metropolis 2.0g/cm3 controls the opposite density base of firebrick.
Omnibus and character, the concussion tenacity of firebrick is tall, applied period is long, and organic chemistry dependability is good, it is good to do not produce exothermic reaction and heat-resisting property with raw material, much more high temperature resistant is spent can accomplish 1900 ℃ . Chamfer of to decoke of converter of furnace of changeover of lukewarm experiment of discretion of plant of very applicable fertilizer, changeover furnace, hydrogenation, flue gas and methane aerification in furnace, steam juice is turned dispersedly since, and strong point, cover and the action that defend activator. Usable also the hot-blast stove with steely enterprise and in adding equipment of lukewarm changeover machine.
Heat preservation brick is a kind of new-style and energy-saving building with raw material of dominant of material of mineral high polymer adiabatic heat preservation is technical, be heat preservation of the wall outside replacing traditional pattern metope is Utopian technical. Heat preservation brick is in of metope of wall of build by laying bricks or stones additional high quality adiabatic heat preservation practical effect be in harmony enters metope in.
The difference of firebrick and heat preservation brick is quite big, their applied environment, category, effect is not same also. Different position can use different raw material, when buying raw material, the net of net of firebrick industry catenary poses the particular case that offers to want basis company oneself, make clear proper fireproof insulation material.
Brick of adiabatic heat preservation how many money together / square? The price of heat preservation brick is very complete transparent, have respectively same computational method. Generally speaking the client can ask a manufacturer the home, manufacturer home can give an a ton value, subsequently can according to ton valence is calculated give a makings value, the value that shows the heat preservation brick nowadays appears palpability completely exceedingly, the price photograph of every manufacturer home is about the same, the production that be worth what carry is every manufacturer home makes level and technical major spend have quite big difference, besides people will be willing to spend same price to buy character apart to hold out big commodity. People often applies purchase heat preservation brick, also can buy false and inferior heat preservation brick sometimes. If it were not for of this kind of firebrick relatively be to one's profit, some awaits the price of heat preservation brick with false and inferior what also is not be to one's profit in those days, did not have method to discern in that way. The price of heat preservation brick still has quite big correlation with commodity raw material and quality, for example the price of clay brick wants than tall aluminous brick many low, mo Laishi brick and price of its corundum brick will be higher. Offer if you wants to buy heat preservation brick to get what the word does not want pure sex to see the value really, consider the quality of commodity even.
