REFRACTORY BOARD TYPES RSBD-LD, RSBD-HD, RSBD-240 AND RSBD-400
2Pages

Refractory Sheet Boards Type RSBD-LD, RSBD-HD, RSBD-240 and RSBD-400 are rigid, high temperature ceramic bodies. They are available in various temperature use and mechanical strength ranges. They feature excellent insulating performance, good high temperature strength and can be custom designed for a broad range of uses. Types RSBD-LD and RSBD-HD They are manufactured using Alumina and Alumina- Silica fibers and high temperature inorganic binders. RSBD-LD, RSBD-HD and RSBD-240 are manufactured with a small amount of additional organic binder which is added to the board formulation for increased handling strength. Where present, the organic binder will burn (600°F) during initial heat up by the end user. Following burnout the boards are white in color. RSBD-400 is pre- fired and will not smoke or outgas when heated. They These materials are fabricated as true composites. The homogeneous microstructure and consistent binder distribution allow this material to be machined to tight exacting tolerances with ordinary shop tools and equipment. Their superior machinability and dimensional stability plus low heat capacity make them SUGGESTED APPLICATIONS Full thickness refractory lining Insulating backup to dense refractories Furnace hot face lining in ceramic kiln, box furnace & petrochemical furnace Board over blanket hot face lining Rigid high temperature gaskets & seals High-temperature baffles & muffles Flue & chimney linings in furnaces & kilns Glass tank side & end wall Heat shields for personal protection Pouring forms for castables Expansion joints Insulating backup to brick & castables REFRACTORY SHEET Types RSBD-LD, RSBD-H ideal for use as setters, supports and process fixtures in both continuous and batch firing furnaces. These materials offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock. They exhibit excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids, as well as concentrated alkalis. If wet by water, steam or oil, thermal and physical properties are completely restored upon drying. ZIRCAR Refractory Composites, Inc. P.O.
