Ceramic Fiber For Boiler Insulation

Q: What is streaming fireproof material?: Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.

Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q: What kind of material is good for cabinet fireproof board: Natural stone marble: Advantage： Rich color, texture is more soft, easy for cutting or molding; shortcomings: Because it is a natural formation, micro cracks will get easily broken. If sewage infiltrates in during production and transportation, it is difficult to clean and it will get cracked. In the daily cleaning, residue will be filled into the cracks when using cloth to clean. then the material will become breed bacteria. In the long process of the formation, natural stone material may cause harm to human health due to the formation of heavy mental which is radioactive.

Q: How to divide the materials according to the National Fireproofing Material Standard?: Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.

Q: How much is the content of boron carbide in refractory material?: Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,

Q: Which one is better, fire-resistant wood or steel?: Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.

Q: Which are roofing fireproofing material?: (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation.
