The low thermal conductivity, low heat capacity ,The thermal stability and excellent thermal shock resistance
1.Product Technology:
Various ceramic fiberboard, a common type counterparts, standards-based, high-purity - containing zirconia ceramic-fiber cotton as raw materials, molding or vacuum drying method of drying by the refining and processing of form. In addition to a corresponding bulk aluminum fine cotton fiber properties, the product of hard texture, excellent strength and toughness with excellent wind resistance capacity. Heating is not expansive, light, construction convenient, arbitrary shear bending, furnace, plumbing and other insulation devices ideal energy-saving materials. 2.Temperature: Depend on the type of heat, atmosphere and material conditions of use. 3.Technical characteristics: The low thermal conductivity, low heat capacity The thermal stability and excellent thermal shock resistance Cool, and with good toughness
