What is the development of the twin screw extruder?

The twin screw extruder has the basic principles of single-screw extruder: solid conveying, melt pressurization and pumping, mixing and stripping and evaporation, but it is not limited to this. The development of twin screw extrusion theory is relatively late, coupled with its wide variety, messy screw shape, and messy extrusion process, which brings many difficulties to the research. And the following words will give you a brief introduction about the information of the twin screw extruder.

What is the future research direction of twin screw extruder?

What is the basic principle of a twin screw extruder?

What is the difference between a twin screw extruder and a traditional extruder?

What is the future research direction of twin screw extruder?

1. Established the physical model and mathematical model of the twin screw extruder to guide the design of the twin screw extruder and the optimization of the extrusion process.

2. It is necessary to understand the relationship between the true state change, the mixing form, the whole process of the structure change and the later mixing and characteristics of two or more polymers and materials during the entire extrusion process.

3. As a twin screw extruder, it establishes the internal connection between the entire reaction process, speed and characteristics of the extrusion reaction molding and the screw structure and operating conditions. It can be extruded through reaction molding.

What is the basic principle of a twin screw extruder?

The twin screw extruder has the basic principles of single-screw extruder: solid conveying, melt pressurization and pumping, mixing and stripping and evaporation, but it is not limited to this. The development of twin screw extrusion theory is relatively late, coupled with its wide variety, messy screw shape, and messy extrusion process, which brings many difficulties to the research.

Generally speaking, the research of twin-screw extrusion theory is still in the development link, which is called "technology more than science". From the perspective of the entire extrusion process of a twin screw extruder, there are about three parts: the polymer's physical state change rule during the extrusion process, the basic principle of conveying, the conveying of solid melt, the exhaust phase and the law, and the establishment of mathematics The physical model is used to guide the planning of the twin screw extruder and the optimization of the extrusion system process.

What is the difference between a twin screw extruder and a traditional extruder?

The traditional extrusion molding process requires rotating a giant screw in the barrel. When using twin screw extrusion, the two screws mesh with each other and rotate together during the extrusion operation. They are installed in the housing on the spline shaft of the barrel. The twin screw extruder can simultaneously ensure food molding, heating, cooling, compression, mixing, pumping and even transportation.

At present, twin screw extruder has become the most common extruder with the largest variety and specifications in the world. Nanjing JlEYA has committed to fulfilling all the requirements of twin screw extruders. And it welcomes global customers to purchase.
