探索出一种液态聚硫橡胶黏度的测定方法。通过对所使用的黏度计在测定时的转速条件论证、转子型号选择条件实验、胶料脱气影响、湿度的条件影响、恒温时间的确定、样品测定杯大小对测定结果的影响等方面的试验与研讨,确定了液态聚硫橡胶黏度测定的相关测试条件。试验结果完全满足液态聚硫橡胶黏度测定的要求,结果稳定准确,并提出了测定结果的表示要求。指出该测定方法完全可以应用于液态聚硫橡胶黏度的测定。

A method for detecting viscosity of liquid polysulfide rubber was explored. The influences of rotor speed, rotor type, polysufide rubber degassing mode, humidity and constant temperature time have been investigated on the viscosity measurement results using the type of viscosity meter. The optimum measuring conditions of liquid polysulfide rubber viscosity have been eventually determined. The viscosity test results have entirely met the requirements of measurement of liquid polysulfide rubber viscosity,and were stable and accurate as well. Furthermore, the expression requirements of viscosity measurement and testing results of liquid polysulfide rubber have been put forward. It was pointed out that this measurement method could be completely applied in viscosity measurement of liquid polysulfides.
