Ceramic fibre Board
Introduction
KSG Board products are a family of rigid, high temperature ceramic fiber boards manufactured in a wet forming process using alumina-silica fibers and binders.KSG Board products offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. They are also well-suited for applications experiencing vibration, mechanical stress and strong erosive forces. The excellent rigidity and modulus of rupture possessed by these boards makes them strong and self-supporting.
KSG Boards once installed, they can help reduce energy costs and cycling times due to their high insulating capability, as well as serving to protect refractory surfaces from thermal shock.
KSG Boards products also resist oxidation and reduction. If wet by water, steam or oil, thermal and physical properties are completely restored upon drying. In order to provide handling strength during the manufacturing process, small quantities of organic and inorganic binders are typically added to the board formulation. Where present, the organic binding agents burn out at temperatures between 230°C to 300°C during initial heat up by the end user. Following burnout of the organic binder, the boards are white in color.
