表面濕潤張力測試液(Wetting Tension Test Mixture)
表面濕潤張力試驗用混合液,用于“塑料薄膜及薄板表面濕潤張力試驗法”的試劑。塑料薄膜的涂裝、涂層、粘附時,要求保留薄膜上的油墨、涂層劑、粘合劑。所顯示的這種保留能力將作為表面濕潤張力的一種尺度。
表面濕潤張力的定義
順次在塑料薄膜上涂上一系列表面濕潤張力不同的混合液,使其恰好濕潤薄膜,由此判定混合液表面濕潤張力(μN/cm){dyn/cm2}的數(shù)值。
單位mN/m表示這種表面濕潤張力的數(shù)值,相當于品名的NO.。例如NO.31的表面濕潤張力是31mN/m (310μN/cm)* dyn/cm=1mN/m (=10μN/cm) (SI單位的統(tǒng)一)
簡便的試驗方法
用含有試劑的棉棒在試驗材料(薄膜)上橫向涂抹一次,必需注意涂上的混合液的量會極大影響試驗的正確度。涂上試劑后2秒,判定液膜中央部分的狀態(tài)。當液膜沒有產(chǎn)生破裂時,判定為“可潤濕”;產(chǎn)生破裂時,判定為“不可潤濕”。
