Description

Technical Field

[0001] The utility model relates to the field of unsaturated resins, in particular to a mixing device used for the production of unsaturated resins. Background Art

[0002] As a key chemical material, unsaturated resin plays an indispensable role in many industrial fields such as composite materials and coatings. In the production of unsaturated resin, quality control of raw materials is a crucial link. Raw materials often contain multiple components, such as monomers, cross-linkers, initiators, etc., and various particulate impurities will inevitably be mixed in during storage, transportation or pre-production processing. These particulate impurities may come from crystallization and dust of the raw materials themselves, or foreign matter introduced from the external environment.

[0003] Traditional production processes usually use independent screening equipment and mixing devices. Usually, the raw materials are first sent to the screening equipment to remove impurities, and then the screened raw materials are transferred to the mixing device for stirring and mixing. This step-by-step processing method has many disadvantages. First, during the raw material transfer process, secondary pollution is easily caused. External impurities may be mixed into the screened raw materials again, affecting the purity of the raw materials. Secondly, the independent equipment layout occupies a large production space, increasing the cost of plant construction and equipment maintenance costs. In addition, since the screening and stirring processes are independent of each other, it is impossible to achieve coordinated optimization between the two. For example, the screened raw materials may re-agglomerate due to long-term storage or accumulation during the transfer process. It is difficult to quickly and evenly disperse when entering the mixing device, affecting the mixing effect. In order to solve the above problems, we propose a mixing device for the production of unsaturated resins. Utility Model Content
