Q:Who know what kind of fire shutter fire rating are there?: The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department

Q:On the problem of making refractory materials: But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!

Q:What a blast furnace refractories generally?: Common refractories often use silica?brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.

Q:The classification of fire-resistant material: There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50～70° and material forms. 3.

Q:Who knows the external wall thermal insulation materials fire rating requirements?: The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q:How to hang the suspended brick in the refractory masonry?: First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.

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:What are the additives and recipes of refractory?: Add FDN.

Q:Is the ball mill used in production of refractories?: Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.
