Masterbatch Granulator Masterbatch Granulator>
Customer demand for masterbatch mainly varies according to the resin, processing method and end use. As far as the United States is concerned, polyolefin masterbatch accounts for 50% of the market demand. The demand for masterbatch above is on the rise. It is a small-scale but fast-growing resin. Due to environmental protection restrictions, fibers are increasingly inclined to use The masterbatch is colored before spinning. The consumption structure of masterbatch in various resin fields is shown in the table.
In the next few years, the application of masterbatch in the following plastic products will increase significantly.
Color masterbatches used for packaging materials, packaging materials, etc. will maintain the first place in growth.
Plastic packaging materials have made great progress in replacing traditional paper and glass in recent years. People's pace of life is accelerating, and disposable tableware has given the packaging industry a new growth point. , , and the use of masterbatch in packaging materials will increase dramatically.
The development direction of masterbatch technology has always been committed to the compatibility of pigments, dispersants and carriers to improve the dispersion of pigments and thereby increase the pigment content in the masterbatch. The following introduces the latest technological progress of masterbatch from three aspects: pigment, dispersant and carrier.
There are few varieties of dispersants in China. The commonly used low molecular weight polyethylene wax is produced by cracking method. It has wide molecular weight distribution, many impurities, odor, and poor dispersion effect on pigments. Titanate dispersants have been developed in recent years, but the dispersion effect is not obvious. The varieties of dispersants should be expanded, especially the varieties dedicated to resins. The quality of the polyethylene wax produced by the Fine Chemical Company of Siping Zhige Mining Exploration and Development Co., Ltd. using a patented hydrolysis method is better than that produced by the cracking method.
The carrier is an important part of the masterbatch. Its function is to enhance the affinity between the pigment and the resin to be colored and to improve the dispersion and mixing of the coloring components and the resin.
Using resin synthesized by metallocene catalysis as a carrier can greatly improve the synergistic effect and dispersion of pigments in masterbatch. Due to the increased dispersion of the pigments in the masterbatch, a more homogeneous phase is obtained and therefore less pigment is used while maintaining color quality. This is because the resin synthesized by the metallocene catalytic method is different from the resin synthesized by the catalytic method. The resin synthesized by the metallocene catalytic method can be used as a carrier to prepare high-concentration color masterbatch with a high color content.
Most of the equipment used in the production of masterbatch is domestically produced. The main equipment, the co-rotating parallel twin-screw extruder and the high and low speed kneader, have reached the requirements for the production of masterbatch after decades of research and development. . The reciprocating single-screw mixing extruder launched by Jiangyin Xinda Plastic Machinery Co., Ltd. in recent years has brought domestic masterbatch production equipment to a new level.
