Determination of viscosity of nylon 6 chips
Thread Content
Please help, experts. I’m new to the nylon industry. I’m facing problems with measuring the viscosity of nylon 6 chips. Are there any specific standards (domestic, international, and corporate)? Thank you.
Hehe, do you mean laboratory testing and analysis? You can search on Baidu; it should be there
Because I’m not majoring in polymers; I’ve studied the theory, but not the experiments. And the resources for each of these areas. There are differences within the company regarding the determination of this viscosity, and we would like to refer to the standards of other companies or the **industry standards.
First, check if there are any national standards. I know that nylon chips are measured using an Ubbelohde viscometer. For reference

98% concentrated sulfuric acid can be used as a blank to measure relative viscosity
