- 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 to distinguish the construction fire-proof material rating?
- Currently the national standards divide building materials as follows: A1, A2, B, C, D, E, F. External wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. Class A is non-combustible, class B1 flame retardant, class B2 combustible, class B3 flammable. Combustion performance grades of building materials and products are divided into class A1, A2, B, C, D, E, F. And grading of flooring materials and pipeline thermal insulation materials is also stipulated separately, whose combustion performance grade is distinguished by the subscript fl and L respectively. ie. Combustion performance grades for ordinary building materials and products are A1, A2, B, C, D, E, F; combustion performance grades for paving material are Alfl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl; combustion performance grades for pipeline thermal insulation material are A1L, A2L, BL, CL, DL, EL, FL.
- Q: What is the difference between wear-resistant material and refractory material?
- Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- In terms of fire protection, fireproof raceway means that it is composed of the material with certain combustion performance and generally made of flame retardant or incombustible?material. While for the refractory raceway, according to GA 479-2004 "Fire Resistant Cable Tray", its most important properties are: Fire resistance of the cable tray should meet with the following requirements: The cable tray of I grade fire resistance should keep the working time more than 60min, of II grade fire resistance should keep the working time more than 45min, and of III grade fire resistance should keep the working time more than 30min. Hope this is helpful for you! Thank you.
