<P>PROBLEM TO BE SOLVED: To solve a problem that a device for obtaining a fine particle in a membrane emulsification method has a limitation in high pressure, and a porus glass membrane for membrane emulsification is required so as to easily obtain the fine particle under low pressure. <P>SOLUTION: The porus glass membrane having uniform micropores formed by a phase separation method is characterized by that a laminated porus glass membrane is integrated by tightly laminating two or more porus glass membranes by thermal fusion without peeling. The laminated porus glass membrane includes different micropore diameters. The laminated porus glass membrane includes a same micropore diameter. The laminated porus glass membrane includes a skin layer of a thin porus glass membrane having a micropore diameter, and a support layer of a thick porus glass membrane having a pore diameter larger than the micropore diameter. The three-layered laminated porus glass membrane formed of different micropore diameters includes the skin layer of the thin porus glass membrane having the micropore diameter, and the support layer of the thick porus glass membrane having a larger pore diameter than the micropore diameter, and is formed by tightly laminating the support layers on both sides so as to sandwich the skin layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
