Polymer viscosity
Thread Content
Hello everyone. May I ask how you experts determine the viscosity value in the production process? What kind of tests are used? Could you explain it briefly?
For substances with a viscosity below 10,000, a viscometer is generally used for measurement, such as water. For substances with high viscosity, the melt index is used as an indicator; the melt index, abbreviated as MI, is a parameter that reflects the flow properties of thermoplastic resin melts as well as their molecular weight. It represents the mass of the melt that passes through a standard capillary within 10 minutes, expressed in g/10min, under certain temperature and load conditions. The value of the melt index can, to a certain extent, reflect the molecular weight of the polymer.

Our online monitoring team is capable of conducting real-time, continuous monitoring of parameters such as the density/concentration of liquids, polymerization rate, viscosity (degree of polymerization), ratio control, phase separation interfaces, and the termination time of batch reactions, by using techniques such as soft sensing and data mining
Are there any other opinions from everyone? Feel free to post, thank you.
