Description

Technical Field

[0001] The utility model relates to the technical field of paint stirring equipment, in particular to a quantitative stirring cylinder. Background Art

[0002] Photocurable coatings, also known as photosensitive coatings, use ultraviolet light as the energy source for coating curing. They are also called UV-curable coatings. They are mainly composed of photosensitive resins, photosensitizers (photoinitiators) and diluents. Some additives, such as heat stabilizers, are added. Pigments and fillers are added when preparing color paints. The stirring cylinder is a device used to mix and stir liquids. Its main components are stirring cylinders, stirring paddles, drive devices, control systems and other components. Its selection is very important for the production of photocurable coatings.
