影响巴布膏剂粘接性能质量评价的因素

目的 :研究影响巴布膏剂粘接性能质量评价的因素 ,为建立标准化的巴布膏剂质量评价方法提供试验依据。方法 :用多功能材料实验机和初黏性测试仪 ,采用 180°剥离、拉伸剪切和黏着力试验方法 ,测试样品的面积、布基纹路和失水量对评价的影响。结果 :同 20mm宽度比较 ,4 0mm宽度样品的剥离强度降低 26%(P<005) ,而对拉伸剪切强度没有明显影响。布基纹路剥离强度横向大于纵向 (P<001) ,拉伸剪切强度纵向大于横向 (P<005)。失水量 35%时拉伸剪切强度最大 ,30%时剥离强度最大 ,20%时黏着力最大。结论 :被测样品的面积、布基纹路和失水量均可影响巴布膏剂粘接性能的质量评价。

Factors of unfluence on quality evaluation of adhensive property on cataplasma

Objective: To provide experimental proof for es ta blishing a standard quality evaluation method of adhensive property on Cataplasm a by studying the factors of effect on evaluation of adhensive quality on Catapl asma. Method: With 180° peel off test, tensile shear and ad hesive force test, the influence caused by the square of samples, texture of f abric base and the moisture loss was tested with multifunctional material tester and first stickiness tester. Result: The peel off strength of 40 mm wide sample is 26% lower than that of the 20 mm wide sample (P<0.05) , and tensile shear strength had no significant difference. The peel off stren gth of transverse fabric base was higher than that of lengthways fabric base(P<0.01). The tensile shear strength of transverse fabric base was lower than that of lengthways fabric base(P<0.05). The sample with 35% moisture los t had a maximum tensile shear strength and the sample which lost 30% moisture lo st had a maximum peel off strength;The sample which lost 20% moisture lost had a maximum first adhensive force. Conclusion: The square of sam ples, the texture of fabric base and the moisture loss of samples can all affect the evaluation of adhensive quality on Cataplasma.
