Defeito de aparência e solução na produção do masterbatch

The main production equipment for producing masterbatch is a twin-screw extruder. The common production process is: pre-mixing.ingredient mixing, extrusion, cooling, cutting, and packaging. Appearance defects are a quality problem for masterbatch products, mostly related to production processes, raw material quality, production equipment, and production environment factors. Common defects include elongated particles, agglomerations, black spots, discoloration, […]

The Difference Between Intermeshing Twin Screw Extruder and Non-intermeshing Twin Screw Extruder

Introduction Extruders are mechanical devices that use heat, pressure, and mechanical shear to process materials. Twin screw extruders, as the name suggests, consist of two intermeshing screws within a barrel. These screws rotate in the same direction, creating a kneading and mixing action to facilitate material processing. Intermeshing Twin Screw Extruder In contrast to non-intermeshing

color masterbatch 2

How To Reduce The Production Cost Of Color Masterbatch?

The process of color masterbatch is that one or more pigments experiences concentration, activation, ground and stabilization, and then is blended and granulated with resin. Therefore, the color masterbatch should not only have good color and dispersion, but also ensure that the mechanical properties will not be damaged and it is better to improve its mechanical properties.

Can’t you tell the different types of extruders?

co-rotating VS counter-rotating In the counter-rotating twin screw extruder, the raw material is transported in a positive displacement similar to that in a gear pump. The speed of the Counter-rotating is lower and the raw materials shear heat is small, raw materials are not easy to decompose, thus it is not high requirements for the thermal stability of
