Q: hat kind of fire retardant materials are there: There are many flame retardant plastics, which are modified on the basis of raw materials, such as flame-resistant ABS, flame-resistant HIPS, flame-resistant PP, flame-resistant PE, flame-resistant the PET, flame-resistant PBT, flame-resistant PC, flame-resistant PC/ABS alloy. Now there are mainly halogen flame retardant, though there are a lot of researches about halogen free flame retardant, the product stability and flame retardant effect remain to be improved. Testing methods of flame retardant materials are mainly: horizontal and vertical combustion, oxygen index method, NBS smoke box , thermal analysis, cone calorimeter, etc.

Q: What's the fire?retardant material of roller shutter fire resistance door ?: It is composited by inorganic materials, and main componets are perlite and inorganic adhesive, etc.

Q: Who knows the model of fireproofing materials?: There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire?rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.

Q: How long is the duration of fire resistance that fireproof window of level B can endure?: Fire proof window of level B is the fire proof window whose duration of fire resistance is not less than 1 hour.　 Technical requirements: One, Materials and fittings (1) the frame of windows draw on steel or wood frames which have certain intensity and are able to ensure the integrity and stability of components. 　(2) Steel frame and layering can use galvanized steel or stainless steel plate. Its selection criteria shall be in line with provisions 5.1 of GB12955< steel fire door general technical conditions >. (4) The internal fillings of steel, wood frames should use non combustible materials. (5) Fire proof windows can opt for qualified products without affecting the performance of fire proof window. Light transmittance of glass shall not be less than 75% of the same layer of ordinary flat glass. 　(6)The sealing material between the frame and the fireproof glass should adopt the nonflammable materials, functioning as the fire blocker. (7)Hardware fittings should be tested for qualified products.

Q: What are the specifications of fire resistant bag?: Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.

Q: Who knows about the criteria of fireproof and thermal insulation materials?: 1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.

Q: How to choose refractory material: Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.

Q: How many refractories are there for boiler above 1200 ℃？: In addition to refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and the like. Refractories often used are azs brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other nonoxide refractory materials, calcium oxide, chromium hemitrioxide, aluminium oxide, beryllia and other refractories. Thermal insulation refractory materials often used are diatomite product, asbestos product, insulation?board,etc. Unshaped refractories often used are repairing?mass, ramming?mass, castable refractory, plastic refractory, refractory mortar, refractory gunning mix, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc.

Q: What's the A grade fireproofing material?: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire?retardant?coating; 9. fire-proof?sealing?material.
