Q:What does fire-resistant insulation coating have?
What is the most famous is that grade A is incombustible thermal insulation material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified micro bead thermal insulation mortar, rock wool board, glass wool board, foam ceramics, etc.
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory includes metallurgical auxiliary materials.
Q:Which plant need to make refractory mould?
Q:what's the seal of fireproofing material?
Organic fire-proof caulking is made by taking organic synthetic resin as bond and compressing the components together after adding fireproofing agent, filler. The putty won't solidify after a long time usage and has good plasticity, can be sealed arbitrarily. This kind of putty is mainly applied in opening's fireproofing and sealing project of construction pipe and electric wire and cable, and it's used with ATD-AB and fire retardant bag together. ATD-AB is a kind of gray powder material, after mixed with water, it can be used for the opening sealing of electric wire and cable or fire resisting wall of wire tunnel. The fire proof blockage is non-toxic, and no smell, has good water resistance and oil resistance with simple construction methods. It's oxygen index is 100 and it belongs to incombustible material. it's refractory time can reach 3 hours, or above or below. as for some projects for perpetual usage, WXY-II will save the project fee and make the project solid. A kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Fire retardant ring
Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
Q:What are the applications of refractory in petroleum?
It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
Q:What are the technical requirements for refractories?
To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
Q:How long is the duration of fire resistance that fireproof window of level B can endure?
The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
