Product information: Ceramic fiber paper is made of selected aluminum silicate ceramic fiber cotton as the main raw material by wet forming process. The slag removal and drying process is improved on the basis of the traditional process, which is characterized by no asbestos, uniform fiber distribution, white color, no stratification, less slag balls (four times centrifugal slag removal), flexible adjustment of bulk density according to the purpose, high strength (including reinforcing fiber), good elasticity and strong machinability. Due to different service temperatures, it is divided into four materials: standard, high aluminum and zirconium containing ceramic fiber paper.
characteristic: Fire prevention: it still maintains complete shape and size after large fire. High temperature resistance: there are two kinds of temperature resistance: 1260 ℃ and 1400 ℃. Thermal insulation: it can effectively prevent or slow down heat transfer. The thermal conductivity at 800 ℃ can be as low as 0.12W / (m.k). Insulation: inorganic silicate material, non-conductive at high temperature. Sound insulation: high noise reduction coefficient. Sealing: it has certain elasticity and can be used for high temperature sealing.
