Low Thermal Conductivity of High-Silica Glass Fiber Felt by Nano-modification

摘要：

　　A large number of small pores were formed in raw high-silica fiber after acid treatment process,these holes exist to improve fiber porosity and reduce thermal conductivity.Nano-modified high-silica glass fiber felts possess excellent water resistant in comparison to the traditional high-silica glass fiber felts,resulting in properties of lower thermal conductivity and better thermal insulation property.It can replace traditional thermal insulation materials such as rock wool felts,silicate felts that which be widely applied as functional structure interlayer,filling layer and composite layer for thermal preservation and insulation,for example parts and equipments for molten metal,high-temperature filters,fireproof and protective materials.In this research,the influence of component,fiber diameter,acid treatment,silicon value,sintering and forming process was also investigated.The effect of processing parameters on the quality of the resultant were discussed.
