Want to understand PP masterbatch, you can talk about its basic ingredients, processing techniques and defects.
Basic ingredients:
Pigment or dye
Pigments are divided into organic pigments and inorganic pigments.
Commonly used organic pigments are: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast red, macromolecule red, macromolecular yellow, permanent yellow, permanent purple, azo red and so on.
Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, red iron oxide, yellow iron oxide and so on.
Processing technology:
The masterbatch is prepared by mixing and dispersing the toner and a resin carrier through a mechanical process, and then granulating. The toner and the resin carrier and other additives are mixed and plasticized by a mixer, and then passed through a plastic extrusion pumping machine. Manufactured into pellets with a diameter of 2.5-3 mm and cooled to the stock to the package. During this period, the dispersion of the toner on the resin carrier is particularly stringent, especially for high-fill masterbatch, which also requires high dispersion. The requirements for the mixer or the twin screw are extremely strict, and the Japanese and Taiwan Liena mechanical equipment are the best.
Defects:
Can make the pigment have better dispersibility in the product, help to keep the chemical stability of the pigment, can store for a long time. Toner will cause dust and other pollution during the process of addition. It will affect the workers and the masterbatch will not.
Inadequate injection temperature control is difficult to blend with rubber, injection molding machine does not add a certain back pressure, the mixing effect of the screw is not good.
