Increasing the temperature in the zones of the final half of the extruder will generally result in lower viscosity and pressure 提高压出机后半部分区域的温度一般可以增大粘度和提高压力。
5.
In a typical extruder with an l / d > 24 normally most of the extension reaction takes place in the first half of the extruder length 在一个常规的l / d > 24压出机上，绝大部分的延续反应发生在压出机长度的前半部分。
