| titleOfInvention | Process for producing polymer microsphere |
| abstract | The invention discloses a microsphere production process, which consists of three unit operations: 1) generating microspheres; 2) quality control of the microspheres; 3) and (4) carrying out aftertreatment on the microspheres. First unit operation, or unit operation 1), includes four basic functions: forcing the microsphere-forming material through a porous membrane to form embryonic microspheres; promoting the embryo microspheres to fall off from the porous membrane; solidifying the embryo microspheres; the cured microspheres are collected and output. The quality control unit operations include the discovery and discharge of oversized microspheres. The post-processing unit operation includes two basic functions: to smooth the surface of the microspheres and to reduce the organic solvent residue in the microsphere matrix. |
