| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系碩士在職專班 === 103 === The experiment illustrates the melted PC(Polycarbonate) through injection machine is successfully jointed with PPS(Polyphenylene sulfide). The PPS needs to be sandblasted and treated with O2 Plasma, and preheated to the constant temperature. The joint strength of PC and PPS could achieve above 500kg which is the best strength of joint, measured by homemade shear strength tester. The experiment also proves advantage of PPS surface treatment: 1. sandblasting can remove impurities on surface. 2. O2 plasma treating on surface can increase surface roughness, cleaning and modification of functional group on polymeric substrates.
The experiment improves traditional epoxy bonding of Retaining Ring that usually takes longer time. It can save time and cost of processing without considering the quality of epoxy glue. The joint strength 500kg of this experiment is greater than that of traditional epoxy bonding 350~400kg.
