Description

Reactor for mixing and stirring epoxy resin

technical field

The utility model relates to the field of chemical machinery, in particular to a reaction kettle used for mixing and stirring epoxy resin.

Background technique

The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain, and the epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble polymers with a three-way network structure. The cured epoxy resin has good physical and chemical properties, so it is widely used in various sectors of national defense and national economy for casting, impregnation, lamination, adhesives, coatings and other purposes.

During the curing of epoxy resin or other reactions, it is necessary to use the reactor to stir for physical and chemical mixing. The reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be realized. Existing reactors are designed according to certain specifications and can be used for mixing liquid-liquid and solid-liquid.
