Extruder and die temperature control
The temperature control of the extruder and the die has a certain relationship according to the different film blowing machines and the melting index and density of the principle particles. The data parameters provided below are only shown as a case, and the actual temperature control needs specific analysis.
Camel temperature control. Temperature setting: 150 ° C, 160 ° C, 175 ° C, 175 ° C, 165 ° C.
Linear control. The temperature of each section is set between 170-180 °C.
If the temperature is too high, the film becomes brittle, the longitudinal tensile strength decreases, the lateral direction fluctuates periodically, and the film may be unstable; if it is too low, the extrusion is difficult.
