Do brick of heat preservation clay and tall aluminium get together light brick which good?

The stand or fall of heat preservation brick is to see heat preservation effect and service life, do brick of heat preservation clay and tall aluminium get together light brick which good? Argillaceous petty gain, economic material benefit, the valuable feature of tall aluminium, material qualitative content is high, these two kinds of products have each profit each, selecting the product that accords with material benefit of use requirement economy is good product.
Brick of heat preservation clay
The small qualitative refractory products of AL2O3 content 30%-46% , belong to firebrick of adiabatic heat preservation. Use clay grog or pledge argillaceous grog is mixed gently but model clay is main raw material, use combustible law production. Burden and water mix make but model pug or slop, with extrusion or pouring shape, dry hind in 1250 ℃ - in atmosphere of 1350 ℃ oxidation firing.
Price of brick of argillaceous heat preservation is in 1000 multivariate a ton, commonly used production technology is to add float bead burn ashes to add content way, also can use bubble law technology. Range of application of brick of argillaceous heat preservation is wide, multi-purpose the thermal insulation in hot project facilities and industrial kiln furnace, can use at having stock of melt of intense high temperature to erode to reach erode the place of action, a fireproof coating, reduce the furnace that be mixed by slag to enrage soot to erode, decrease mar, the working temperature of goods does not weigh the experiment temperature of the change that burn a line more than. Brick of argillaceous heat preservation belongs to much stoma kind a kind of light qualitative insulation material. Is porosity of this kind of material in 30% ? 50% , sex of its heat preservation is poor, but mechanical strength is as better as the function that fight corrode. Dimension of norms of standard of brick of light qualitative clay is 230*114*65mm, bulk density is 0.75-1.20g/cm3, compression intensity is 2.0-5.9mpa, thermal conductance is 0.221-0.442w/(m.k)(1350 ℃ ) .

Tall aluminium gets together light brick
Use high quality aluminous aluminous raw material, with get together light ball is made burn lost property, via advanced manufacturing technology, high temperature agglomeration and into, have higher compressive strength and high temperature capability, thermal shock stability is good, use heat of kiln of Yu Zhonggao lukewarm industry extensively, tall aluminium gets together light brick is current use new data is recommended in design of industrial kiln furnace. The kiln furnace liner that applies extensively at the industry such as metallurgy, mechanical, pottery and porcelain and chemical industry (do not suffer solution erode) and heat-insulation layer, it is a kind of good energy-saving product. Its use temperature is to be in under 1350 ° C. Tall aluminous qualitative adiabatic firebrick can be used at build by laying bricks or stones to build thermal insulation and erode without stock of melt of intense high temperature reach erode the place of action.
Goods has strength tall, thermal stability is good, the heavy change that burn fine is little, coefficient of thermal conductivity is small wait for an advantage. Get together price of light tall aluminous brick is in 2000 multivariate a ton, also differ according to the difference price of aluminous content, particular value needs to produce the decision after manufacturer talks things over with firebrick. Get together the AL2O3 content of light tall aluminous brick 60% above, fireproof temperature 1600 degrees, specific gravity 0.4-1.35g/cm3, 1-8MPA of intensity of porosity 0.66-0.73% compression.
Brick of heat preservation clay and tall aluminium get together the distinction of light brick (the Al2O3 content of 1) clay brick is low, the Al2O3 content of tall aluminous brick is high, although contain Al2O3, but the respect such as both function, utility is distinguishing. (2) is above the exterior, argillaceous brick and tall aluminous brick also have very big difference, coming to what argillaceous brick and tall aluminous brick use distinguish commonly so is the surface examines a way. (3) clay brick is fireproof degree be in commonly 1580 ℃ - 1750 ℃ , loading bate temperature is in 1250 ℃ - 1450 ℃ . And tall aluminous brick is fireproof degree control in 1770 ℃ , loading bate temperature is in 1420 ℃ - 1550 ℃ . Of argillaceous brick and tall aluminous brick fireproof degree relatively as adjacent as loading bate temperature, but both use environment still has certain difference. (4) looks from character, it is GB firebrick together, argillaceous brick and tall aluminous brick each respect function differs very few, performance of the corrode that fight broken bits is good, be opposite especially acid slag, it may not be a bad idea of thermal shock stability. (5) looks from index, the brick of clay of compression intensity prep above of tall aluminous brick, the impact resistance it may not be a bad idea of that tall aluminous brick at argillaceous brick. (6) we distinguish from firebrick price, tall aluminous brick because Al2O3 content is high, its price also brick of prep above clay, accordingly, argillaceous brick satiable kiln furnace need not be to use tall aluminous brick. Do brick of heat preservation clay and tall aluminium get together light brick which good? The stand or fall of heat preservation brick is to see heat preservation effect and service life, do brick of heat preservation clay and tall aluminium get together light brick which good? Argillaceous petty gain, economic material benefit, the valuable feature of tall aluminium, material qualitative content is high, these two kinds of products have each profit each, selecting the product that accords with material benefit of use requirement economy is good product.
Fireproof material occurrence craze, fall off, easy how to wear away to do?
