使用NDJ-79型粘度计的有关问题探讨

摘要

In view of some problem existing in using NDJ-79 viscometer ontesting the viscosity of modified starch size liquor in national cotton mill and size plant,the Conical Bottle Method was suggested in testing the viscosity of size liquor,the accuracy,stability and constancy of the test result would be increased by the going up tempreture(≥95℃) and the bowl of №Ⅲ unit with the factor 5.%针对目前国内纺织厂和浆料生产厂在使用NDJ-79型粘度计测定变性淀粉浆料粘度时存在的有关问题，提出：使用“锥形瓶法”制备测粘用浆液，使测试温度大于等于95℃，并采用第Ⅲ单元、因子数为0.5的转筒进行测试，能提高测试结果的准确性、稳定性和可比性。
