Fireproof Calcium Silicate Insulation Board Asbestos Free ISO9001
Description:
Calcium silicate board is an asbestos-free thermal insulation product that can withstand continuous operating temperature from 650C up to 1100C. It is light weight, low thermal conductivity, high strength, easy to install, reliable and durable. There are 3 grades available namely 650 &1000 & 1100 which are commonly used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction. It not only provides energy saving, also increases production efficiency and gives personnel protection in industrial safety aspect. And in the housing construction Calcium Silicate Board is also used as the ceiling, fireproof and heat insulation materials of wall and sound absorption materials of decoration.
Applications:
Reheating furnace -Annealing furnace-Transfer ladle -Rotary kiln-Glass tank Dip tubes and spouts Nozzles -Shuttle kiln -Tunnel kiln -Aluminum melting and holding furnace- Distribution boxes, Flow gates Hot pipe supports-Other high temperature ovens or heat processing equipments
