Abstract

Background: With the improvement of the properties of plastic products, people gradually realize that the mixing capacity of extruders cannot meet the requirements of fully mixing materials, especially for nano-composites, colored products. In order to improve the mixing level of materials, static mixers are widely used. Researchers developed different types of static mixers to meet the purpose of homogenizing different materials. The mixed materials can achieve different levels of mixing with different types of static mixers, which provided a favorable research condition to study the change of the properties of the mixed materials.

Objective: This paper reviews the research progress of different types of static mixers in polymer processing, including the improvement of processing equipment, processing methods and static mixers, and expounds the influence of different types of static mixers and different processing methods on polymers.

Methods: The paper reviews various patents and research developments about the structure of different types of static mixers, and the application of static mixers in plastic processing. It also analyzes the advantages and disadvantages of a variety of patented technologies from the aspects of internal structure, micro-morphology, test methods, and equipment cost.

Results: Through the application of static mixer in plastic processing, the current and future development trend of static mixer in plastic processing is put forward to improve the quality and properties of composites.

Conclusion: Static mixers are widely used to improve the performance of mixtures. In recent years, there are many researches on the application of static mixer to improve the morphology, appearance and mechanical properties of polymer composites, blends as well as foams. The patents and technologies about static mixer provide some good references for improving the properties of multicomponent materials. It is still difficult to improve the properties of some mixtures. In order to further strengthen the properties of composite materials, better methods and equipment about static mixers are needed.

Keywords: Patents, polymer, processing equipment, processing method, static mixer, structural improvement.
