本研究選擇以雙軸延伸試驗模擬IMD(In-mold Decoration;模內裝飾)製程在高壓成形時,油墨與薄膜所受之雙軸向應力,其優勢在於試驗後之試片為平面更易於觀測,並且能明確的掌握油墨與基材所受到的變形量。以延伸倍率為參數,分別對BOPET膜在對稱與非對稱的表面裝飾圖形於延伸後之應力場觀測,以及在延伸後BOPC膜之物性、應力分布、破壞行為、油墨之光學性質與介面性質作探討,應力場的觀測選用光彈性實驗施行,從上述一系列的實驗以獲得最佳之加工條件參數與成品設計原則。
對所使用之油墨進行沉降速率與粒徑分布的分析,其實驗上使用L.U.M.(Labor-Umweltdiagnistik & Medizintechnik)之Dispersion Analyser LUMiSizer,以光學離心的分析方法,利用粒子遷移速率與光的穿透關係,記錄下隨著時間改變之粒子行為。
This study selects biaxial stretch experiment simulating IMD(In-mold Decoration) process during high pressure forming; the biaxial stress that ink and film must bear, its superiority is,after experiment; the sample is flat, which is easy to observe, besides; it can precisely control strain that ink and substrate must bear. Take draw ratio as parameter,to observe stress filed regarding BOPET film respectively on symmetrical and non-symmetrical surface decoration graphic after stretch, as well as reviewing physical properties、stress distribution、destruction behavior of BOPC film、optical and interface property of ink after stretch. The photoelastic experiment is selected and performed for observation of stress fields, from afore-mentioned a series of experiments to obtain optimal processing conditional parameter and finished product design principle.)
To proceed the analysis on ink used about sedimentation rate and particle size distribution. The experiment uses Dispersion Analyser LUMiSizer of L.U.M.(Labor-Umweltdiagnistik & Medizintechnik), with optical and centrifugal analytical method in making use of relationship between particle mobility rate and light transmission to record particle behavior accompanying time change.
