Description

Technical Field

[0001] The utility model relates to the technical field of hydrogel production equipment, in particular to a mixing device for producing hydrogel ointment. Background Art

[0002] Hydrogel is a high-performance material mainly used in agricultural, medical and industrial fields. The production process of hydrogel mainly includes steps such as raw material preparation, mixing, gelation and drying. First of all, the main raw materials of hydrogel include polymers, crosslinkers, solvents and additives. Among them, the commonly used polymers are deacetylated cellulose, sodium polyacrylate, etc., and the crosslinkers are mainly ethylene glycol diglyceride, glycine, etc.; the solvent is generally water or organic solvent; the additives can be thickeners, antioxidants, disinfectants, etc. according to actual needs. Mixing is a key step in the production process of hydrogel, and its purpose is to fully mix the various raw materials. First, add the polymer, crosslinker and part of the solvent into the mixing container and mix them evenly by stirring equipment. Then, gradually add the remaining solvent and additives, and continue stirring until the mixture is evenly mixed. Next, the mixed material needs to go through the gelation process to transform it from liquid to gel. Generally, heating or adding gelling agent is used for gelation. Heating gelation mainly causes crosslinking reaction between polymer and crosslinker by increasing the temperature to form a three-dimensional network structure. Adding a gelling agent means adding the gelling agent to the mixture, and reacting with the polymer and the cross-linking agent to gel the system. Finally, the gelled material is dried to remove excess solvent and water to make it a finished hydrogel. The main drying methods include natural drying, hot air drying and vacuum drying. Among them, vacuum drying is a commonly used drying method, which allows the gel to dry quickly by rapidly evaporating water or solvent under vacuum conditions.

[0003] A stirring and mixing device for hydrogel production with publication number CN213493703U includes an operating table, a stirring kettle fixed at the center of the operating table, and a stirring rod fixed at the center of the stirring kettle.

The utility model can efficiently and evenly stir the hydrogel during the cross-linking process, and the produced hydrogel is more uniform and stable.
