Q:what's the requirements of refractory for forge furnace?
High temperature resistance, good slag resistance.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
When sealing the gaps between glass curtain wall and floors of all layers and the outer edge of the partition with rock wool or mineral wool, its thickness should not be less than 100mm and should be filled densely; Rock wool or mineral wool for horizontal smoke prevention zone between floors should use galvanized steel sheet whose thickness is not less than 1.5mm to support; The gaps between supporting plate, major structure, curtain wall structure and supporting plate should be filled with fire-resistant glass, whose fire endurance should meet the design requirements. Fire-resistant glass for curtain wall are mainly include monolithic fire-resistant glass as well as the hollow glass and laminated glass made by monolithic fire-resistant glass.
Q:What material is used for making refractory stone bowl?
Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
First, it is prohibited that the thermal insulation material of level B2 and below combustion performance is used in the thermal insulation project of any civil building wall, and the thermal insulation material of below level A combustion performance is used in the thermal insulation project of curtain wall civil builduing that the height is equal and greater than 24m, of non-curtain wall residential building that the height is equal and greater than 100m and of other non-curtain wall civil builduing that the height is is equal and greater than 50m. Civil builduing wall thermal insulation project must strictly enforce the "civil builduing external wall thermal insulation systems and external wall decoration fireproofing interim provisions" (referred to as "fireproofing interim provisions").
Q:Can anyone say something about what A-level fire-proof decorative material is?
Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt
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:What's the function of aluminium dihydrogen phosphate on the refractories?
Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
Q:What is the classification standard of fireproofing material levels?
Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. Class B2: Combustible building materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
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:What's the feature of construction external wall fireproof and thermal inuslation matertial?
Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
