The principle of extrusion for PE pipe production line?

 

The plastic manufacturing industry is a highly integrated technological Sex industry chain.

It involves Polymer chemistry, polymer physics, interface theory, plastic machinery, plastic processing mold, formula structure design and process control. The key scientific research of Línea de producción de tubos de PE theory is the movement and trend of plastic in an extruder. The relationship between the three physical conditions of polymers that occur in an extruder under external forces and different temperature ranges, as well as the screw structure, plastic properties, and production and processing standards. Then carry out reasonable process control. To achieve the goal of improving the production and quality of plastic products. Plastic polymer materials, when heated under constant pressure, exhibit three physical states: glass state, high elasticity state, and viscous flow state within different temperature ranges. Usually, the molding temperature of plastic is above the viscous flow temperature.

The rotation of the screw causes shear force to break the plastic; The rotation of the screw causes the driving force to cause the broken plastic to continue moving forward, resulting in compression pressure; Under the squeezing pressure effect, the filter plate and other positions where the pressure reaches cause a reaction force (i.e. back pressure), leading to the flow and mixing of plastic, thereby completing the all-round balance of the Línea de extrusión de tubos de PE process. This functional process is the standard and necessary condition for plastic to achieve uniform plasticization.
