Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch mixing, in particular to a dosing device for masterbatch mixing. Background Art

[0002] Masterbatch preparation refers to the process of mixing base resins or solvents with pre-dispersed pigment concentrates (i.e. masterbatches) in a certain proportion in order to obtain products of a specific color in industries such as plastics, coatings, paints, and silicones. Masterbatches are composed of highly concentrated pigments or dyes, carriers (usually resins that are compatible with the polymers used in the final product), and additives (such as dispersants, stabilizers, etc.).

[0003] In the masterbatch preparation process, the raw materials and masterbatches need to be dosed. The dosed process generally involves adding the selected masterbatches and additives to the raw materials for uniform mixing. Since a mixing device needs to mix materials of different colors, the inside of the mixing device needs to be cleaned when mixing materials of new colors. Generally, cleaning fluid is sprayed on the inside of the mixing device using a water gun for cleaning. Workers' cleaning can easily lead to poor cleaning effects and incomplete cleaning of the inside of the mixing device. Utility Model Content
