Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch sampling, in particular to a quantitative sampling device for the production of plastic additive masterbatch. Background Art

[0002] Masterbatch (English name Masterbatches) is the full name of plastic masterbatch, also known as masterbatch. It is a kind of plastic processing aid that developed in the 1980s. It is composed of excess chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading an excess amount of pigments (dyes) in the resin. Masterbatch refers to the granular material obtained by mixing and kneading the required various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then measuring, mixing, melting, extruding, pelletizing and other processing processes such as extruders. Masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives or the content of fillers in the masterbatch is several to ten times higher than the required amount in the actual plastic product. During the molding process, the ratio of masterbatch to base resin must be adjusted according to the content of the relevant components in the masterbatch and the amount required to be added in the actual product. Masterbatch can usually be divided into ordinary filler masterbatch (referred to as filler masterbatch) and functional masterbatch, such as color masterbatch, anti-drip masterbatch, etc.

[0003] In the process of manufacturing cooked plastics, in order to ensure the quality of masterbatches, it is necessary to frequently sample and test masterbatches and Xining.
