The hot aseismatic stability of fireproof material and its composition, characteristic and preparation craft are concerned. It is the crucial factor that a few influences heat up aseismatic stability below:
Composition and stuff kind: The fireproof material of different type has different hot aseismatic property. Expensive aluminous fireproof stuff, carborundum is fireproof material, zirconia is fireproof the material heat with be had better is aseismatic function. The fireproof stuff kind that chooses to suit specific applying is aseismatic to rising stability is very important.
Crystal structure: The crystal structure of fireproof material can affect his to heat up aseismatic function. Certain crystal structure is stabler, and next not incidental photographs change or in high temperature the structure is destroyed, improved the hot aseismatic performance of fireproof material thereby.
Heat up coefficient of expansion: The hot coefficient of expansion of fireproof material heats up aseismatic function with its closely related. If the hot coefficient of expansion of fireproof material and all round the structure does not match, stress concentration and rupture may be caused when temperature is elevatory. Accordingly, the fireproof material that chooses to heat up coefficient of expansion to match is very important.
Grain dimension and micromechanism: The grain dimension of fireproof material and micromechanism can affect his to heat up aseismatic function. Lesser grain has better aseismatic performance normally, because they conduce to,dispersive stress is mixed absorb thermal stress.
Function of cold hot loop: The function of cold hot loop of fireproof material is a main index, it inspected material to be in warm up quickly and drop in temperature the stability in the process. The preparation craft of material and quality control can affect his function of cold hot loop.
Chemical stability: Fireproof data is eroded possibly in high temperature environment by chemistry, this may reduce its to heat up aseismatic stability. Accordingly, the chemical stability of material also is one of consideration elements.
The treatment of material and installation: The treatment of material and installation method can affect his aseismatic function. Right material choice, preparation and installation are to ensure fireproof material is in high temperature environment the main factor that maintains stability.
The place on put together is narrated, the hot aseismatic stability of fireproof material suffers a variety of element effects, include dimension of structure of composition, crystal, hot coefficient of expansion, grain, micromechanism, cold heat circular function, chemical stability and treatment and installation. Accordingly, when choose and using fireproof data, need considers these factors integratedly, ideal aseismatic stability and property are acquired in order to ensure in high temperature environment.
