Brick of light qualitative adiabatic heat preservation because structure environment of complex, work is harsh, the factor that affects result of its heat insolation accordingly is very much. And each elements are affected each other, photograph interconnection is, very hard choice undertakes definitely analytic study. But, in numerous influencing factor, density of the material composition of brick of light qualitative adiabatic heat preservation and structure, porosity and stomatic feature, bulk, temperature is main factor.
As energy-saving fall of bad news policy gain ground, the research and development of brick of heat preservation heat insolation and application also got extensive development. Can see from the database, brick of brick of argillaceous heat preservation, Mo Laishi heat preservation, tall aluminium gets together light brick these 3 kinds of commonly used bricks still be the heat preservation with client big demand adiabatic series. Henan area all the time since be brick of high quality heat preservation is important give producing area
The heat in the adiabatic and fireproof material such as brick of heat preservation heat insolation delivers cent to undertake through solid photograph deliver and pass what gas undertakes to deliver two parts. Below microtherm, basically be heat of solid according to legend; Below high temperature, heat of gas according to legend is very important. Conduct to reduce the heat of solid photograph, need chooses the solid look with low thermal conductance, still need to reduce the interface between solid particle to accumulate. For example, crystal structure is more complex, the phonon of scattering is more, thermal conductance is lower. The structural integrality of polycrystal and regular sex are poorer, the influence of impurity of together with crystal boundary and distortion, thermal conductance is lower than monocrystal. Be like again, stomatic can scattering phonon. Usually, porosity increases, can reduce thermal conductance. Still have, use globose small particle, make quantity of heat can be passed only small osculatory area is delivered between particle, the heat that also can lower solid body greatly is conducted.

Raise brick of heat preservation heat insolation to lie between the way of heat energy force? ① increases porosity; ② reduces stomatic size; ③ increases the complexity of various organization structure; ④ reduces the contact of solid photograph; ⑤ mix into adds shading substance, block up radiate conducts heat.
Brick of heat insolation of the hollow ball heat preservation that make uses alumina of common introduction of product of brick of heat preservation heat insolation alumina is hollow pink of corundum of ball, report frit, α - stone of line of Al2O3 small pink, SiO2 small pink, silicon and argillaceous pink are raw material preparation to have fight flake the alumina of function. Brick of heat insolation of the heat preservation of light aggregate and combustible that make uses polystyrene bubble ball, expand collosol of fiber of pearlite pink, Mo Laishi, clay, silicon serves as raw material, the brick of heat insolation of light qualitative heat preservation that goes out through extrusion preparation. Traditional bubble legal system makes brick of heat insolation of calcic feldspathic heat preservation make main raw material with cyanite, made bond develop calcic feldspar to combine Molaishi with white cement light qualitative adiabatic firebrick.
