摘要
对粉末注射成形粘结剂组分的热力学参数进行了计算 ,并通过实验观察得到了组分相容性的判据。分别以PVB ,EVA ,PMMA为高分子组分 ,讨论了它们与低分子量组分PEG的相容性 ,并通过混炼机混炼和偏光显微镜观察 ,得到了ΔG/T <1.5可工艺相容、ΔG/T >3.
Thermodynamic parameters of binder ingredients for powder injection molding were calculated. These ingredients of binder were mixed in order to get a means to determine theoretically the compatibility of ingredients. Polymers, such as PVB, EVA and PMMA were used respectively to mix with PEG. The micrograph of PEG PMMA mixtures is also adopted to certify that when ΔG/T< 1.5 , binder ingredients are compatible, while ΔG/T>3.0, binder ingredients are incompatible. [
