本文首次提出了微孔注射-压缩成型（MICM）技术，以寻找改善发泡件微孔结构的有效途径。采用MICM和标准微孔注射成型（MIM）对厚度为5,4和3mm的矩形发泡聚苯乙烯板进行了成型。与MIM样品相比，MICM样品沿样品轴的三个位置外区更薄，以不规则条纹状细胞为主；MICM样品外区细胞形状和大小分布较为均匀，内区三个位置的细胞结构较为均匀，尺寸较小，以椭球状细胞为主。在MICM样品中改进的细胞结构导致其在玻璃态下具有更高的存储模量。基于三种厚度试样的细胞结构，提出并深入分析了MICM压缩阶段的细胞发育机制。此外，对于3、4和5 mm厚的样品，使用MICM可以使最大空腔压力分别降低约18.6%、29.3%和55.6%。变异较大。ENG。科学。[j] .中文信息学报，2014。©2013塑料工程师协会
A novel technology, being called as microcellular injection-compression molding (MICM), was proposed for the first time to search an effective way for improving the cellular structure of foamed parts. Both MICM and standard microcellular injection molding (MIM) were used to mold rectangular foamed polystyrene plates with the thicknesses of 5, 4, and 3 mm. Compared to the MIM samples, the MICM samples exhibited thinner outer zone, in which irregular striation-shaped cells were dominated, at three positions along the sample axis; the MICM samples exhibited a little more uniform cellular shape and size distribution in the outer zone, and more uniform cellular structure with smaller sizes in the inner zone, being dominated by ellipsoidal cells, at three positions. Improved cellular structure in the MICM sample leads to its higher storage modulus in the glassy state. Based on the cellular structure in the samples with the three thicknesses, a cellular development mechanism in the compression stage during MICM was proposed and analyzed thoroughly. Moreover, using the MICM can lower the maximum cavity pressure by about 18.6, 29.3, and 55.6% for 3, 4, and 5-mm-thick samples, respectively. POLYM. ENG.
