| PP管材在生产的时候，是可以通过挤塑加工而成的，在挤出成型过程中，物料塑化和制品的质量和产量均有十分重要的影响。在挤出成型过程中，物料从粒状固态进入挤出机后，要完成输送、压实、熔融、均化直到高温熔融型坯从机头中挤出，其温度变化非常复杂，而且也不容易测定。因此，能否很好地解决挤出成型温度控制问题，将直接影响到挤出PP管材过程能否顺利进行和管材质量的好坏和产量的高低。 Pipes can be processed by extrusion during production. In the extrusion process, the quality and output of plasticized materials and products have a very important impact. In the extrusion process, shusongji.89ix.comshusongjiw.89ix.comwanquji.89ix.comgubinlongw.89ix.comwhen the material enters xieliaoji.89ix.comshuzhiwaw.89ix.comthe extruder from the granular solid state, it must be conveyed, compacted, melted and homogenized until the high temperature melted billet is extruded from the die. The temperature change is very complex and it is not easy to measure. Therefore, whether the extrusion temperature control problem can be well solved will directly affect whether the extrusion process of PP pipes can be carried out smoothly, the quality of pipes and the output level. 要正确控制挤出成型温度，当然是需要先了解被加工物料的承温限度与其物理性能及相互关系，再从中找到一定的特点与规律，这样就能够选出合适的温度了 In order to control extrusion temperature correctly, it is necessary to know the temperature-bearing limit of the processed material, its physical properties and the relationship between them, and then find out some characteristics and rules from them, so that the appropriate temperature can be selected. |
