ceramic fiber blanket

Product Description

Jiuqiang Ceramic Fibre Blanket is made of special ceramic long-fiber that is produced by the melting of very pure raw materials in double surface meeding process with out binders and with good stability in a large range of temperature. The process of double surface needing increase interweaving and tensile strength. Its unique fiber layup and needling process provide Jiuqiang Ceramic Fibre Blanket with outstanding consistency, handling strength and resiliency at elevated temperatures. Characteristics 1)Excellent thermal stability 2)Excellent chemistry quality 3)Resistance to burning 4)Low thermal conductivity 5)Low heat storage 6)Good obstructing voice and mechanism strength 7)Low shrinkage 8)Good springiness for fibersConvenient producing and installing Applications 1)Joint sealing and filling insulation (kiln car, pipeline, kiln door and so on) 2)Fiber composite (for example: grinding parcel) 3)Internal and external lining for industrial furnace 4)Structure refractory and sponging sounds 5)Materials for hot filtration 6)Raw materials for further producing 7)Technical Specifications Technical Data: Type Ordinary Standard High Purity High Aluminium Zirconia Classification temperature ***0 ***0 ***0 ***0 ***0 Working Temperature < ***0 ***0 ***0 ***0 ***0 Color white spotlessly white spotlessly white spotlessly white spotlessly white Density (kg/m3) *6 **8 *6 **8 *6 **8 **8 **0 **8 **0 Shrinkage on heating (%) (*4 hours, density as **8/m3) －4 (***0) －3 (***0) －3 (***0) －3 (***0) *3 (***0） Thermal conductivity by different temperature (w/m.k) (density as **8kg/m3) 0.*9(**0) 0.*6(**0) 0.*9(**0) 0.*6(**0) 0.*9(**0) 0.*6(**0) 0.*0(***0) 0.*2(**0) 0.*0(***0) 0.*6(**0) 0.*0(***0) Tensile strength (MPa) (density as **8kg/m3) 0.*4 0.*4 0.*4 0.*4 0.*4 Chemical composition (%) AL2O3 *4 *6 ****9 ****5 ****0 AL2O3+SIO2 *6 *7 *9 *9 - AL2O3+SIO2+ZrO2 - - - - *9 ZrO2 - - - - ****7 Fe2O3 <1.2 <1.0 0.2 0.2 0.2 Na2O+K2O ≤0.5 ≤0.5 0.2 0.2 0.2 Size (mm) Spec.：***0×**0×****0；Other sizes can be available.
