Brick of light qualitative heat preservation namely the product of a kind of firebrick that we often use in kiln furnace construction, at the same time we also say for air brick. Pledge heat preservation brick is distinguished somewhat with the firebrick that we use commonly gently, choosing what pledge we pay attention to heat preservation brick gently is action of its adiabatic heat preservation. Accordingly, we are chosen high quality board shape corundum, Molaishi is aggregate, with silicon line Shi Fu closes for matrix, buy particular kind additionally additive mixes refine with a few rare earth oxide, classics high pressure shapes, high temperature is firing. Let us understand brick of light qualitative heat preservation now.
Brick of common light qualitative heat preservation deserves to compare according to our manufacturing raw material, have clay qualitative, tall aluminous qualitative excel in bleachs bead brick, low Tiemolaishi, tall aluminium gets together light adiabatic firebrick, firebrick of diatomite heat insolation, because this pledges gently,the composition of heat preservation brick is decided by different raw material place.
Commonly used manage of light qualitative brick changes target:
The item characteristics of brick of light qualitative heat preservation:
Light qualitative brick has the character such as shake of tall loading, low creep, high fever, brick of light qualitative heat preservation with its peculiar poriferous structure, those who hold a product of traditional pottery and porcelain concurrently is fireproof, flame retardant, acid-proof alkaline wait for function, density is small, sound insulation, adiabatic wait for a characteristic, it is current industry energy-saving environmental protection turns commendatory fireproof and adiabatic product. Satisfying heat preservation requirement while won't make structure of body of heater has loaded again big, reduce kiln furnace to be opposite of resource, the sources of energy use up integratedly.
Brick of light qualitative heat preservation has characteristic of the following nine:
1, weight is light: Its do light qualitative brick absolutely the capacity is 500-700Kg/m*3 only, it is the 1/4 of common concrete, argillaceous 1/3, hollow piece 1/2, because its unit weight is less than water, common calls float the aerocrete on surface.
2, heat preservation, adiabatic: Because aerocrete is in production process, interior formed small air hole, these stoma form air layer in material, improved result of heat preservation heat insolation greatly, make the coefficient of thermal conductivity of aerocrete is 0.11-0.16W/MK. Heat preservation effect is 5 times of argillaceous brick, 10 times of common concrete.
3, contractive value is little: Because used high quality river arenaceous regard silicon as simple stuff with fine coal, its systole value is only 0.1- - 0.5mm/m, can guarantee wall system won't craze.
4, impermeable: The stomatic structure of this product, make its capillarity poor, bibulous guide wet slow, with bulk 5 times needing time to saturated place is argillaceous brick more bibulous.
5, environmental protection: Make, carry, use process free from contamination, protect farmland, energy-saving fall bad news, belong to building materials of green environmental protection.
6, aseismatic: Same building construction uses light qualitative brick to raise tall and aseismatic level than argillaceous brick.
7, fast: Long-term strength stabilizes aerocrete, can use for a long time.
8, machinability: This product weight is light, norms size is diversiform, the design is made convenient.
9, fireproof: Fireproof degree it is 700 degrees, for one class fireproof material, fireproof function amounts to the block with large 100mm 225 minutes, fireproof function amounts to the block with large 200mm 480 minutes.
The manufacturing technology of brick of light qualitative heat preservation is roughly same, different is us tie-in to the raw material of the brick of light qualitative heat preservation of different type. In current our country brick of light qualitative heat preservation is produced on, we use the manage of different raw material to change character, make pledge heat preservation brick owns better property gently, in order to get used to the fireproof data market that demand improves ceaselessly.
