Q:Who knows the external wall thermal insulation materials fire rating requirements?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.

Q:What refractories can withstand high temperature above 2100 degrees?: Well, what can you heat to 2100 degrees? ? The dryer? What you used are all substance of low-melting point, which cannot withstand even 1000 degrees. "Is the maximum temperature of refractory bricks 1500 degrees?" Do you mean refractoriness or operating temperature? Firstly, a dryer is impossible to reach 2100 degree. If it does, you might as well use high chrome brick for oxidizing atmosphere. You can use silicon?nitride brick for non-oxidizing atmosphere. But I guess it is enough for you to use clay brick, but the price differs a lot! ! !

Q:The performance of refractory material: As for easticity modulus, you can serach for information on the Internet or specialized books.

Q:What kinds of fireproof materials does the safe use?: The fireproof materials of safe, copper is one of the most widely used material of locks for its good mechanical performance, corrosion resistance and processibility and beautiful colors.

Q:what's the fireproof levels of fireproof and thermal inuslation matertial?: at present,thermal insulation and fireproofing materials on the market include inorganic thermal insulation bead board(Shanghai Benniao construction and energy saving decoration materials company) rock wool (Hebei Shenzhou glass wool products co., LTD.) foamed glass ceramic (Nanjing Institute of Building Research) or sogou search.

Q:How to apply the alumina powder on refractories?: What kind of the refractories can make the aluminium oxide increase the aluminum content and specific gravity, and erosion-resistant.

Q:Could you tell me how does fire protection standard of decorative material is divided?: Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.

Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?: the fire endurance of fire window is: class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, Class C window is not less than 0.6 hour. technical requirements: 1, materials and accessories (1) the window frame is made by a certain strength of steel frame or wooden frame which is sufficient to safeguard the integrity and stability. (2) steel frame and mound layer can select galvanized?steel?sheet or stainless steel plate. Its selection standards should be in line with the provisions of Article 5.1. in GB12955 "Steel Fireproof Door General Technical Condition" (3) the selection standards of wood frame and mound layer should be consistent with the provisions of Article 5.1.1. in GB14101 "General Technical Conditions of Wooden Fireproof Door" (4 ) the inner filling material of steel and wood frame should be non-combustible material. (5) fireproofing glass can choose the qualified products in fire resistance test and not affecting the fire windows. light transmittance of glass is not less than 75% of identical layers of ordinary plate glass. ( 6) a sealing material between the frame and the fireproofing glass should use the nonflammable material, it can play the role of fireproofing and smoke insulation in the fire disaster. I hope I can help you

Q:How can refractory material of the electric furnace be used for longer.: Minimize mechanical shock, Electrical furnace commonly referred to must be electrical arc furance. The wall of electric arc furnace should be constrcuted with magnesite carbon brick. Its hearth permanent layer should be constrcuted with mansornary magnesia brick. High alumina brick is usually used to aviod furnace cover suddenly get hot and cold. But its service life is lower. At present integral casting furnace cover is made of alumina magnesia. Terminal will be created even without the use of refractory material. Consumption is much faster if using refractories material or whole knottiing mainly.

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.
