表面湿润张力测试液 表面张力润湿液 试验用混合液

表面湿润张力试验用混合液,用于“塑料薄膜及薄板表面湿润张力试验法”的试剂。塑料薄膜的涂装、涂层、粘附时，要求保留薄膜上的油墨、涂层剂、粘合剂。所显示的这种保留能力将作为表面湿润张力的一种尺度。
 
表面湿润张力的定义
 
顺次在塑料薄膜上涂上一系列表面湿润张力不同的混合液，使其恰好湿润薄膜，由此判定混合液表面湿润张力（μN/cm）{dyn/cm2}的数值。
单位mN/m表示这种表面湿润张力的数值，相当于品名的NO.。例如NO.31的表面湿润张力是31mN/m (310μN/cm)* dyn/cm=1mN/m (=10μN/cm) （SI单位的统一）
 
简便的试验方法
 
用含有试剂的棉棒在试验材料（薄膜）上横向涂抹一次，必需注意涂上的混合液的量会极大影响试验的正确度。涂上试剂后2秒，判定液膜ZY部分的状态。当液膜没有产生破裂时，判定为“可润湿”；产生破裂时，判定为“不可润湿”。
