- Q: How to divide the fire resistant level of EVB?
- 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. I hope I can help you!
- Q: How to divide fire rating of decorating materials ?
- I am very happy to answer this question for you. It can be divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability. I hope my answer is helpful to you, thank you.
- Q: what's the classification of fireproof and thermal inuslation matertial?
- 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
- Q: How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
- Q: Fire rating of decoration materials
- You can refer to (code for fire protection design of buildings)
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
- Q: How should fireproof building materials be ranked?
- Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.
- Q: Is aluminium oxide refractory material?
- Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming?mass, impressionable plastic material, gunning mix and refractory mortar.
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- Refractory materials used in special applications include high temperature oxcide, such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconia and other, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, mainly contain metal ceramic, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: I wanna ask about the thermal insulation material fire resistant level?
- The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.
