Q: What kinds of fireproof and fire retardant materials are there?: general classification of fire retardant materials will use A, B in the home improvement supplies. A has the best flame resistance, followed by B.

Q: What's the fire endurance of fire windows?: Fire endurance of fire doors and fire windows stipulated by the fire prevention norm: Fire endurance of A class fire door or fire window is 1.2h rather than 1.5h, and fire endurance of B class fire door or fire window is 0.9h rather than 1.0h. Fire prevention code doesn't explicitly state that the fire door has thermal insulation function, so it can definitely be interpreted that the fire door only has fire integrity. For the fire door without heat-shielding performance, at certain distance from the unexposed surface, it has strong thermal radiation and is easy to hurt people. For the A class thermal insulating fire door, its fire integrity is 0.1h shorter than that of the corresponding fire door stipulated in the specification, but its heat-shielding performance and integrality is improved. All in all, compared with the specification that the fire integrity of the A class fire door should be 0.6h, it has much more improved its performance.

Q: Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: There is no difference between them because they are the coating with the same texture. But generally galvanized treatment is not necessarily needed for brushing fireproof coating. Fireproof coating and galvanized surface have relatively poor bond strength. So it is advisable to bursh trasitional lacquer or micaceous iron on galvanized surface.

Q: Refractory materials are needed for casting metallurgy.: High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.

Q: Why should graphitic refractory materials be used now that graphite can burn?: Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.

Q: What are the types of refractory sealant?: Refractory sealant has low exothermicity and will form a hard corking content during burning, it includes: Liquid polysiloxane has at least two active groups selected from alkoxy, hydroxy and alkenyl; a cross-linking agent, a catalyst, a reinforcing filler and wollastonite. These cured silicone rubber sealant has low heat release and will form a hard coking content structure while buring. Refractory sealant composition can be used in sealing structure to prevent flames, air and other steams passing. 1. In a liquid organic polysiloxane polymeters, each R1 is independently selected from the alkyl, aryl, alkenyl and haloalky which has 1-18 carbon atoms, and each R2 is independently selected from the hydroxy, alkoxy, alkenyl, and X is an integer from about 10 to 1,500. 2. A crosslinking silicone compound having at least 3 silicon-bonded eactive groups. 3. A R2 pressed of silicon bonding capable of promoting component A. 4. Wollastonite and a selective reinforcing filler.

Q: What are the requirements for fire?rating of construction suspended ceiling material ?: According to No. 42 ducument of department of housing construction and Ministry of Public Security: fire?rating of building suspended ceiling material should reach A level. Other civil buildings: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission

Q: What are the requirements on fire resistance period of C-level fireproof glass?: What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
