摘　　要：通过分析黏胶的表面张力、黏度和熟成度,研究不同变性剂对黏胶过滤性能的影响。研究结果表明:变性剂A、变性剂B、变性剂C均能明显降低黏胶的表面张力,从而提高黏胶的过滤性能;变性剂A对黏胶表面张力降低的影响最为明显;3种变性剂对黏胶的熟成度及黏度都无明显影响。By analyzing the surface tension,viscosity and maturity of viscose,the influence of different types of denaturants on the filtration performance of viscose was studied.The results show that denaturant A,denaturant B and denaturant C can significantly reduce the surface tension of viscose,thus improve the filtration performance of viscose,among which denaturant A has the most obvious effect on the surface tension of viscose,and the three denaturants have no obvious effect on the maturity and viscosity of viscose.

关 键 词：过滤性能 黏胶 变性剂 表面张力 黏度 熟成度
