QN-1.0 pledges clay brick is a kind of new-style light qualitative heat-insulating material gently, basically use at the heat preservation heat insolation of kiln furnace and adornment. As a result of its inferior coefficient of thermal conductivity and better heat proof quality, had made kiln oven a kind of of energy-saving domain important material.
QN-1.0 pledges the limits of safe use temperature of clay brick gets gently the influence of a variety of elements, include bricky body material, density, heat to conduct coefficient, hot coefficient of expansion to wait. Generally speaking, the limits of safe use temperature of brick of light qualitative clay is left and right sides of ℃ of 200 ℃ ~800. Exceed this temperature range, the function of brick of light qualitative clay can be differred the influence of degree, may appear fall off, be out of shape, the problem such as craze, affect service life and security thereby.
To ensure the safety of brick of light qualitative clay is used, need controls temperature strictly in be used actually, avoid to exceed its safety to use temperature range. In the meantime, in construction process, need notices to choose proper bricky body density and ply, and accurate construction method and installation means, assure the heat proof quality of brick of light qualitative clay and service life thereby.
Those who need an attention is, its safety uses the brick of light qualitative clay of different type temperature limits may differ somewhat, specific should undertake choose and be used according to actual condition. In addition, in be used actually, still should observe relevant kiln furnace standard and standard, ensure the safety performance of kiln furnace and wear.
