当一种塑性材料受力时,只要不消除施加的力它就会连续变形,而一旦消除施加的力,仍会保留大部分变形。塑性试验是用于保证材料的批次质量和材料的一致性。由于很难确切给出在混炼机或挤出机中的材料性能,所以,塑性试验主要是用于检测各批胶料的均一性和质量。压缩(平行)板可塑计 When a plastic material is subjected to force, it will continue to deform as long as it does not eliminate the applied force, and will retain most of the deformation once the applied force is removed. Plastic test is used to ensure the quality of the material batch and material consistency. Since it is difficult to give exact material properties in a mixer or extruder, the plasticity test is mainly used to check the homogeneity and quality of batches.
