Abstract

It is shown that the injection molding of thin-walled products with a thickness of less than ~1 mm can be difficult in the case of particulate-filled polymer composite materials (PFPCMs) with MFS-1, MFS-2, and HFS types of structure. Products with a wall thickness of more than ~3 mm and L/h ≤ 100 can be obtained by injection molding using almost all PFPCM structure types (DS, LFS, MFS-1, MFS-2, and HFS) at the processing temperatures. However, when the L/h ratio increases, the products may be difficult to process using injection molding. For the first time, dependences are established for pressure losses at injection molding on generalized parameters and PFPCM dispersion structure type and product size. Such an approach makes it possible to predict and choose the required process parameters and injection molding machines for processing the majority of PFPCMs with different types of dispersed structures based on polymer matrixes and solid dispersion fillers.

各种结构颗粒填充高分子复合材料制品的注射成型

 抽象的

结果表明，对于具有 MFS-1、MFS-2 和 HFS 类型的颗粒填充聚合物复合材料 (PFP​​CM)，厚度小于 1 mm 的薄壁产品的注塑可能会很困难。结构。在加工温度下，使用几乎所有 PFPCM 结构类型（DS、LFS、MFS-1、MFS-2 和 HFS）通过注塑成型可以获得壁厚大于 ~3 mm 且 L/h ≤ 100 的产品。然而，当L/h比率增加时，产品可能难以使用注射成型进行加工。首次建立了注塑过程中压力损失对广义参数和 PFPCM 分散结构类型和产品尺寸的依赖性。这种方法使得预测和选择所需的工艺参数和注塑机来加工大多数具有不同类型的基于聚合物基体和固体分散填料的分散结构的 PFPCM 成为可能。
