Description

Technical Field

[0001] The utility model belongs to the technical field of polyurea coating production, and particularly relates to a sealing device for a polyurea coating dispersion kettle. Background Art

[0002] A polyurea coating dispersion kettle is an industrial device specifically used for preparing polyurea coatings. Through its efficient dispersion and mixing functions, the components of the polyurea coating are evenly distributed to ensure the quality and performance of the final product. The polyurea coating dispersion kettle makes the coating components in the kettle generate strong shear force and turbulence through the rotational movement of the stirring device, thereby achieving uniform dispersion. The temperature control system keeps the temperature in the kettle stable. The whole process ensures the quality and performance of the polyurea coating. During the production process of polyurea coatings, many raw materials and solvents are volatile. Due to the poor sealing performance of the dispersion kettle in the related technology, volatile substances will escape, resulting in material waste and increased production costs. And the escape of volatiles will also pollute the production environment and affect the health and safety of workers. Summary of the Invention
