Principle of twin screw plastic extruder

Article source: Popularity:- Data2016/9/19 14:12:50

The principle of double screw plastic extruder first introduced the double screw extruder extruder with the principle of single screw extruder solid conveying melting pressure and pumping mixed stripping and devolatilization, but not so simple. Study on twin screw extrusion theory started late, coupled with its type, screw extrusion process of complex geometry and complex, which brings many difficulties to the research. On the whole study of twin screw extrusion theory is still in the initial stage, this is called "multi skills in scientific research from the extrusion." it can be divided into three parts:

Changes of state during the extrusion process, 1 polymer melt conveying principle of solid conveying and exhaust the truth rule, establish a mathematical physical model is used to guide the optimal design of twin screw extruders and extrusion process.

2, to understand polymer and material more than two kinds of material in the extrusion process of the real situation, mixed form, the process of structural changes, as well as the relationship between the final mixture and performance.

3, as a twin screw extruder, the reaction process, speed, performance and screw configuration, operating conditions of the intrinsic link between the reaction, the establishment of the model, used to guide the reactive extrusion.
