Q:What type of firebrick does TZ-3 represent?
Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).
Q:how to divided the external wall thermal insulation materials fire rating
The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:What level is the rock wool board fireproofing material ?
The most important feature of the rock wool board is fireproofing, which is a non-combustible material and absolute A-level! It has the specialized external wall rock wool board, which can be found online.
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
I think that graphite is the only one.
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:How is the fire endurance of the fireproof paint?
fire endurance of fireproof paint is from 1 to 4 hours. Mechanism: Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. fireproof paint decomposes with heat and releases non-combustible inert gas, thining out the flammable gas produced by the protected object, making it difficult to burn or slow down the burning. expansive fireproof paint expands under heat and forms a layer of carbon foam insulation to cover the protected object, delay the heat transfer in the substrate , prevent burning and possible losing of fireproof abilitiy because rising temperature.
Q:What are the insulation fireproofing materials?
Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
Q:What are fire ratings of wall thermal insulation material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincal records of production, provincal records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province! Generally speaking, the combustion of phenolic aldehyde is grade B, but it can barely reach A2 when a thin layer of mortar is wiped outside.
