- Q: what is the grading standards of external wall thermal insulation materials?
- What is the grading standards of external wall thermal insulation materials? summarizing the three versions of GB8624 (1997,2006,2011) external wall insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. the dividing is based on many technical indicators. It takes time to explain for It is professional and technical. For details, please contact Qingdao Shan Textile Instrument. they specialized in external wall insulation fire rating tester.
- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
- Q: How about the prospect of refractory material?
- Cost reduction Refractory material is affiliated to base material factories such as steel, cement and glass. But the situation becoms more severe due to lmaterial reduction and waste. It is necessary to find a substitutional raw material.
- Q: How to distinguish the fire?rating of 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 grade. 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) and polyethylene (PE), etc. The information given is for reference only. Hope it will help you.
- Q: The development prospect of fire-resistant material
- Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.
- Q: Why the corundum can be used as refractory
- Because the main component of corundum is aluminum oxide!
- Q: Who knows the fire endurance of B-level fireproof doors and windows?
- Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
- Q: who knows the fire endurance of fireproof coating?
- this is not specfied , depending on design requirements. The products we made have fire endurance from 1to 4hours . We have not done any higher.how is the fireproof coating in improving fire resistance of building components? finishing fireproof coating; wood fireproof coating; fire-resistant coating for steel structure, fire-resistant coating for concrete structures, tunnel fire retardant paint, fire retardant paint for the cable. Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required.
- Q: What refractory materials are used in power plant
- Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
