Thermal properties of ceramic wool.

Aluminum silicate wool asw is based on the al2o3 sio2 system and is in use since more than 50 years. Fire resistance properties of ceramic wool fiber reinforced intumescent coatings n. Refractory ceramic fibres rcf or alumino silicate wool asw blankets made from kaowool cerablanket cerachem and cerachrome with temperature capabilities up to 1425 c 2600 f. Thermal ceramics offers high temperature fibre blankets for applications in thermal management and passive fire protection.

It is a very versatile material and can be manufactured to many different densities to give varying properties formed in various shapes and faced with a. The exceptional thermal fire and acoustic properties of mineral wool derive from the mat of fibres that prevents the movement of air and from mineral wool s inert chemical composition. Othman1 b and f. The intumescent coatings were formulated from expandable graphite ammonium polyphosphate melamine boric acid bisphenol a epoxy resin be 188 polyamide amine h 2310.

The high temperature wool also referred to as ceramic fiber or refractory ceramic fiber rcf has fundamentally changed plant engineering and furnace construction due to its properties. They can also be amorphous or have inhomogeneous chemical composition which develops upon pyrolysis of organic precursors the high process temperatures required for making cmcs preclude the use of organic metallic or glass fibers only fibers stable at temperatures above 1 000 c 1 800 f can be used. Thermaxx proudly uses fiberfrax ceramic fiber insulating blanket and mats. Bühl in concise encyclopedia of advanced ceramic materials 1991.

The results of influence of glass fiber addition into the basic intumescent coating formulation towards the enhancement of its thermal insulation properties are presented. Low biopersistent fibres are provided as superwool blankets with. The fiberfrax blanket and mat product family is a group of lightweight thermally efficient ceramic fiber insulating materials that combine the advantages of dimensional stability at high temperatures with complete resistance to thermal shock. Ceramic fiber materials are required for the thermal insulation of the hot gas zones of components carrying process gases.
