Viscosity Experiment FAQ
Q: What is the method used to measure the molecular weight of sulfonated polyacrylamide?
A: measured sulfonated polyacrylamide viscosity average molecular weight with Wu's viscometer method, Hangzhou Wang in the automatic Wu's viscosity instrument can be obtained in the software directly viscosity average molecular weight.
Q: can Ubm viscometer calculate the molecular weight of polymer?
A: Ubbelohde viscometer measures the viscosity average molecular weight of the polymer, and the molecular weight is determined by the intrinsic viscosity.
Q: After measuring the viscosity with an Ubbelohde viscosity meter, the calculated slope of the two straight lines is positive, what is going on? In the case of
A: Is the molecular weight measured? It is possible to measure the concentration of the solution a little bit, try increasing the concentration.
Q: how to choose the viscosity of PET PET measured viscosity?
A: solvent phenol and tetrachloroethane ratio of 3: 2 can be used when the inner diameter of 0.88mm Uygur viscose tube, solvent phenol and tetrachloroethane ratio of 1: 1 can be used when the inner diameter of 0.84mm Wu's viscosity tube.
Q: How is the molecular weight of polyacrylamide measured?
A: using 1mol / LNaCl solution as a solvent, U wall viscosity tube with a diameter of 0.55-0.57mm viscosity tube, so that the solvent out of time between 100 ~ 130s, by formula to obtain viscosity average molecular weight.
