| 摘要 |
According to the invention, the stirring device by electromagnetic entrainment is applicable to magnetic stove plates and comprises a cylindrical metal bar (2) enclosed in a glass tube (1) which has two teflon, polyethylene or polypropylene parts (3, 4) pressed thereon at the ends, said parts being provided with fan-like fins (5) whose plane is situated at 40 ... 60 degree from the stirring device axis in order to increase the liquid turbulence. The stirring device is used to homogenize the solutions, the reaction media or to precipitate the polymer solutions at temperatures up to 150 degree C, in ordinary glass vessels not exceeding a volume of 600 ml.
