Steps of producing color masterbatch

Industry News, 10-29-2021

The carrier resin of color masterbatch used for coloring plastic products belongs to powdered polypropylene. The following content introduces the steps involved in the production of this product that everyone is interested in.
1. Selection of carrier resin
The color masterbatch with heavy calcium as filler has a wide range of applications. The selection of carrier resin for masterbatch use is the key to obtain masterbatch products with performance price ratio. The disadvantage of using powdered polypropylene as the carrier resin is that the processing temperature is high, and when the master batch melt leaves the die, it cannot be granulated in the form of air-cooled hot cutting.
2. Selection of heavy calcium
The production and application practice of more than 20 years of color masterbatch shows that 400 mesh heavy calcium powder is an economical raw material, but not all heavy calcium powder is welcomed by masterbatch manufacturers and plastic weaving enterprises. The key lies in the whiteness and color of heavy calcium powder and the wear of metal parts (screw, screw, mold, blade, etc.).
3. Processing equipment and process
High speed mixer is used for drying and surface treatment of heavy calcium powder. In recent years, the structure of high-speed mixer has been greatly improved according to the characteristics of powder processing.
The starting point of equipment selection is to have good mixing effect, high output under the same manpower and energy consumption, strong adaptability to material types and component changes, stable and lasting continuous operation, etc., while the requirements for temperature control system can be relatively relaxed.
The plastic woven products have better mechanical properties when the fine particle size of heavy calcium is fully dispersed. However, with the increase of the mesh size of heavy calcium powder, the use of additives and carrier resins needs to be increased, leading to a significant increase in the raw material cost of color masterbatch. Therefore, its comprehensive effect should be considered from both technical and economic aspects, and personalized products should be provided for different users.
