Apparatus and method for manufacturing sol, gel and silica porous body

摘要

The present invention relates toWhile effectively mixing the mixtureThe solarization of the mixture is progressed under fully controlled conditions.Industrially producing homogeneous solsAndInduces the sol-gel transition with phase separation process.Manufacturing gels having co continuous structures between the backbone phase and the solvent phaseAndIt is an object of the invention to provide an apparatus and method capable of manufacturing a silica porous body having a macropore.The present invention comprisesA sol manufacturing apparatus (1) that produces a sol for use in the manufacture of a silica porous body having macroporesSilica precursorA mixed portion (11) comprising a catalyst and a macropore forming agent to prepare a mixtureA first supply part (12) which supplies a silica precursor to a mixing part (11) andA second supply portion (13a) for supplying the catalyst and macropore forming agent to the mixer (11) in a mixed state;A discharge tube (14) for discharging a mixed liquid (m) from a mixing part (11) andThe cooling liquid (15) flowing through the exhaust pipe (14) is provided with a cooling portion (15) for cooling down to 35 ° C. or less.A sol production apparatus (1) is provided.Diagram
