Specifications
1:Excellent thermal stability and chemical stability 2:Keep loose ,soft and elastic under high temperature 3:Low heat storage
The ceramic fiber are manufacturered from high purity raw materials:alumina powderAI2O399%, silica sandSiO99% for the high temperature grades and zircon sandZrO266%is also used. The ceramic mixture is heated in an high temperature electric furnace and the stream of molten material is drawn into fibres by eithter spinning or blowing. It is produced by advanced "blown" and "spun" processes. Ceramic fiber bulk show a high temperature stability ,low weight and heat capacity and an outstanding sound absorption is complemented by their resistance to shock and erosion . The polycrystal alumina fiber cotton is made of melt aluminum salt throught chemical colloid method.The solution are heated and inspissated into fiber under specific conditions and got polycrystal alumina fiber after heat treatment.
Features:Excellent thermal stability and chemical stabilityKeep loose ,soft and elastic under high temperature,Low thermal conductivity and heat storage Excellent thermal shock resistanceNo bond and corrosive materialExcellent sound absorption perfomance
Application:Base material for the production of board,paper, abnormity etcFilling material for expansion gap or short-term heat insulation mendingFIber strengthen material for heat insulation beton and bonding agentMixture product
