ceramic fiber board

heat insulation ceramic fiber board    /high temp ceramic fiber board /  thermal ceramic board/ceramic fiber board NR ceramic fiber boards, adopting corresponding spun fiber  (COM.ST.HA.HP.HZ)   as the  material ,are produced by vacuum formed technology.  The ceramic fiber board does not only possess the same function of fiber but also has hard texture excellent toughness and intensity and excellent fiber resistant  and heat preservation. NR ceramic fiber board are made of different refractory fiber bulks with excellent chemical stability, organic and inorganic bond by wet method and vacuum forming processing which is applicable to many kinds of industries .The fiber board with a characteristics of hard, flexible, excellent strength and resistance against corrosion.   Product Characteristics Low heat storage   Wide bulk density, 260-320kg/m3 Variety grades, the boards can be classified by temperature1100ºC-1430ºCLow thermal conductivity and shrinkage Excellent resistance against chemical attack Easy to machined, cut and install Product Applications: Furnace constructions: Liners of industrial furnaces, masonry insulation layer High-temperature equipment insulation:  Kin liner, kiln cars, door baffles of  high-temperature furnace.Typical Specifications Ceramic Fiber Board Density: 240-320 kg/m3 Grade: 1260 /1350 /1430  Size: 900x600x20-50mm   Typical Product Data Sheet  STD         HP           HA        HZ Classification Temperature         1260           1260            1350        1430 Working Temperature(?)         1050          1100              1200        1350 Max.
