| titleOfInvention | A kind of standby continuous hollow SiO of coaxial spinning2The method of porous fibre |
| abstract | The present invention relates to a kind of coaxial standby continuous hollow SiO of spinning 2 The method of porous fibre, method include：Silicate or silanol colloidal sol are prepared into spinning solution；Acid solution is added in coagulating basin as coagulating bath, in addition a identical acid solution is as coaxial spinning sandwich layer spinning solution；By spinning solution and coaxial spinning sandwich layer spinning solution with identical flow velocity through in the injection coagulating bath of coaxial spinning syringe needle, carrying out reaction wet spinning, obtaining hollow orthosilicic acid/silicate fiber, winding, ageing, is washed with deionized to neutrality, carry out solvent displacement, it is dry to get.The method of the present invention has the characteristics that equipment is simple, raw material is cheap and easily-available, reaction process is simple, good spinnability.The hollow inorganic SiO that the method for the present invention obtains 2 Porous fibre has the abundant hole, specific surface area of superelevation, high temperature resistant, resistant to chemical etching, and advantage is had more than common porous fiber in fields such as catalysis, absorption and filterings. |
