Brick of light qualitative heat preservation, main effect is heat preservation, reduce caloric prediction of a person's luck in a given year to improve thermal efficiency then. It is a kind of science, efficient energy-saving technology measure, make caloric sends out the measure that conducts speed to decelerate.
If by boarding fireproof material is divided in fireproof material, brick of light qualitative heat preservation and firebrick (use property without heat preservation) basically be current most extensive,
However, heat preservation brick and firebrick are having very big distinction actually:
1, heat preservation function
The coefficient of thermal conductivity of brick of light qualitative heat preservation is in commonly ℃ of 350±25 of 0.2-0.4(average temperature) W/m.k, and the coefficient of thermal conductivity of firebrick is in ℃ of 350±25 of 1.0(average temperature) W/m.k above, many the heat preservation performance that can reach the heat preservation function of heat preservation brick wants to compare firebrick from this is good.
2, fireproof degree
Of brick of light qualitative heat preservation fireproof degree be in 1400 degrees commonly the following, and of firebrick fireproof degree in 1400 degrees of above.
3, density
Brick of light qualitative heat preservation is light qualitative insulation material commonly, density is general the density of in 0.8-1.0g/cm3 firebrick is in basically 2.0g/cm3 above.
Brick of light qualitative heat preservation does not contact content of melt of blaze, high temperature and chemical gas directly commonly erode, firebrick reachs manage to change function to be able to use all sorts of eroding at enduring what the broil with direct blaze bakes content of melt of the high temperature in the furnace that reach kiln character according to different capable person.
In respect of scope of application, the application of firebrick is far the use frequency that is more than heat preservation brick. But, in last few years, as environmental protection the buildup of energy-saving consciousness reachs what high temperature heats up effect to use, the application with heat preservation wide also brick purchases limits in what kiln furnace build by laying bricks or stones builds in. Appeared especially bricks of all sorts of new-style light qualitative heat preservation: Brick of Mo Laishi heat preservation, tall aluminium gets together light brick, alumina is hollow ball brick.
Anyhow, heat preservation brick and firebrick are belonged to finalize the design the main product of fireproof material. When equipment of industrial kiln furnace, high temperature is purchasing material, according to actual condition, want to combine the technical butt joint of firebrick manufacturer, purchase applicable fireproof material.
