High temperature ceramic fiber wool paper
JIUQIANG ceramic fiber thermal insulation paper is manufactured from high-grade ceramic fiber with low slag ball content, and formed into excellent flexible sheet through unique beating, deslagging, slurry-compounding, long net forming, vacuum water removal, drying, cutting and rolling processes.
It is featured with high temperature resistance and heat insulation and high anti-melt capability, very low thermal conductivity, chemical corrosion resistance and thermal shock stability.
So the paper can be widely used in building, glass industry for teeming pads separation. It provides maximum heat resistance and thermal insulation in limited space.
Typical Application of ceramic fiber paper
Die cut gaskets between castings in coke oven doors, blast furnace hot air piping, aluminium heat treating furnace, tuyeres and heat treat furnaces. Backup for brick and monolithic refractories in blast furnace stoves, piping, tundish, ladle, hot metal cars, trough etc. Mould wrapping for controlled cooling SEN isulation wraping Shield for welding & brazing operation Rotary klin back-up insulation Fabricated into tapout cones for Aluminium industry. Strips in bottom of ingot mould for sealing Expansion joint packing Induction coil liner Mould liner Silencer interleaf Ladle & tundish insulation Asbestos paper replacement Hot top linings Thermal and electrical insulation.
