Ethyl cellulose Measurement of Viscosity

 

1. Instrument

1.1 Rotary viscosimeter

1.2 125ml white wide mouth grinding mouth bottle.

1.3 Magnetic Stirring Vessel

2. Test  process

 

2.1 Accurately weigh 5 gram samples drying two hours under 100-105  (accurate to 0.01 g), put the samples into 125ml white wide mouth grinding mouth bottle and add 95 g appropriate mixed solvent, then cover the plug, stir on the magnetic stirrer until the samples completely dissolved, and put this bottle in the constant temperature water bath to preserve 1 h under the temperature 25  +-0.1 . at last, Test the viscosity with Rotary viscosimeter

 

3. Test Results

 

Take two test average value for the final results.

Note: Parallel test allows difference less than 5%
