摘要: | 本研究乃針對在射出成形的過程中,剪切操作對於PC/ABS聚摻物抗拉強度的影響進行研究。採用一可主動控制剪應變速率之射出成形模具,在實際射出成形過程的保壓階段,對熔融PC/ABS聚摻物直接施予各種不同速率的剪切操作,並依據標準抗張試驗規定,進行射出成形品的抗張強度測試。
研究結果顯示: PC的重量比例低於80%之PC/ABS聚摻物,施予剪切操作後,其抗拉強度之物性值均有增強之效果。 This study focuses on the tensile strength affected by shearing operation on PC/ABS blends during an injection-molding process. A mold which can control shearing rate is adopted to perform different shearing rates to melting state of PC/ABS blends on actual holding pressure stage. Then, the tensile strength of the specimens are tested according to a specification of the tensile-strength standard. This result shows that the tensile-strength values increase after shearing as the weight fractions of PC are under 80% in the PC/ABS blends. |
