Firebrick cent pledges to pledge gently and be weighed, do not suit to be used at housetop heat insolation normally. Although firebrick has better fireproof performance and thermal stability, but they normally relatively close-grained, thermal conductivity is taller, do not have good heat proof quality. Light qualitative firebrick is compared normally light, but the price is expensive, do not suit to be used at housetop heat insolation, can raise architectural cost.
Under photograph comparing, normally with the material at housetop heat insolation need pledges gently, heat proof quality is waterproof and good, moistureproof wait for character. Common housetop heat-insulating material includes polystyrene bubble board (EPS) , polyurethane foam board, vitreous cotton, cliff cotton, they have good heat proof quality and inferior coefficient of thermal conductivity, suit to be used at housetop heat insolation, can reduce the specific power consumption of the building effectively and promotion easy is measurable.
Light qualitative firebrick is the firebrick of a kind of special kind, compare the common firebrick at the tradition, it has lighter weight and better heat proof quality. The firebrick of this kind of type uses light qualitative data normally or add light qualitative aggregate to make, in order to reduce its density and weight, maintain its at the same time fireproof function.
Pledge the main characteristic of firebrick includes gently:
Inferior density and weight: Compare at common firebrick, the density of light qualitative firebrick and weight are lower, make its more agree with to build the circumstance with bear inferior requirement a few pairs, also reduced the cost that carry and installs at the same time.
Good heat proof quality: Light qualitative firebrick uses high-powered heat-insulating material to make normally, have better heat proof quality, can reduce quantity of heat effectively to conduct, raise a building can effect function.
Fireproof function: Compare with common firebrick, light qualitative firebrick does not have apparent difference normally on fireproof function, still can bear the thermal stress below high temperature environment.
Easy processability: Because light qualitative firebrick is relatively soft, relative to easy cut and treatment, because this is in,a few situations that need custom-built appearance or measure have an advantage more.
Light qualitative firebrick applies extensively in equipment of equipment of all sorts of industrial furnace kiln, heat treatment, hot tool and building, it is the high temperature stuff with a kind of good performance.
Accordingly, although firebrick has its specific use in a few special high temperature places, but do not suggest to use its at housetop heat insolation, righter choice is the heat-insulating material that uses special design.
