Q:Can the teflon material resist fire?: Teflon does not burn and with the ability of flame retardant.

Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?: the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .

Q:what grades are fire resistance of fireproofing glass divided into?: Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.

Q:How long is the fire endurance of the rock wool board?: When the average temperature reaches 140 degrees Celsius or 180 degrees Celsius, it starts to lose the fire insulation function.

Q:Which refractory is better for building 1500 degree kiln ?: High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.

Q:What's the A grade fireproofing material?: Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".

Q:What's meaning of CN of fire-resistant material?: The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.

Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q:What are the materials of white firebricks?: White refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.

Q:What's the texture of refractory for the hearth of reverberatory?furnace? ?: High alumina brick; you can use zircon brick under the temperature above 1700? ;may i use mullite bricks under the temperature from 1400 to 1700? you can use clay brick and heavy corundum brick under the temperature of below 1400 degrees, question closely: what's the usage temperature of reverberatory?furnace? < pre accuse = "qRA" > is there someone use refractory fiber?
