Description

Technical Field

[0001] The utility model relates to the technical field of continuous preparation of high molecular polymer solutions, in particular to a device for continuous preparation of high molecular polymer solutions. Background Art

[0002] Solution polymerization is an important synthesis method in the process of polymer synthesis. It is usually carried out at the reflux temperature of the solvent, which can effectively control the reaction temperature and dissipate the heat released by the exothermic reaction by evaporation of the solvent. In industry, solution polymerization is suitable for occasions where polymer solutions are directly used, such as coatings, adhesives, synthetic fiber spinning solutions, etc. The continuous preparation device for polymer solutions is used for continuous preparation.

The high level alarm and the low level alarm can feedback the high and low powder levels of the medicine in the dry powder hopper. The weighing system automatically weighs the medicine. Finally, the spiral dry powder pusher automatically transports the material to the box for dissolution. It has the advantages of accurate dosage concentration and no waste of medicine.

Therefore, a continuous preparation device for a polymer solution is needed. Utility Model Content
