Q:What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q:Does anyone know the characteristics of refractory for glass kiln?
Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
Q:Can the teflon material resist fire?
Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
How long is the fire resistance time of the AAA fire resistance rolling shutter door?
Q:What is the fire endurance of fireproof glass cotton?
Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass silk λ=0.043W/m2K. good fireproof performance, it's fire-resistant capacity is more than 1000 ℃.
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.
Q:What high-molecular polymers can be used as fire-resistant material binder?
Lignin is the least expensive.
Q:What's the requirements of fire-fighting criteria of heat insulating material?
Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
Q:Are refractory materials and fireproofing materials the same?
The refractory material and fireproofing material are not the same in the strict sense. Refractories refer to non-metallic materials of which refractoriness are higher than 1580 degrees. Now commonly used heat insulation materials can also be considered as refractory materials. The fire endurance of fireproof materials reaches certain requirements. Its test temperature is 540 degrees. Range of applications for two material are not the same. Refractory materials can be used in high-temperature region as it can withstand high temperature. Fireproof materials can not be used under high temperatures for a long time.
Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
Which standard? Please be more specific
