How to detect the viscosity and particle size of polyacrylamide

This special report will explore in depth how to detect the viscosity and particle size of polyacrylamide, focusing on key detection technologies in industrial and application contexts.

Viscosity test method

There are several methods for testing the viscosity of polyacrylamide:

• Capillary viscometer method: Use the flow time of liquid in the capillary to measure viscosity, suitable for low viscosity liquids.
• Rotational viscometer method: Viscosity is calculated by rotating a disk or cone surface and measuring the resistance. It is suitable for medium and high viscosity liquids.

Particle size analysis steps

Particle size analysis is mainly divided into the following steps:

1. Sampling: Prepare and evenly distribute the polyacrylamide sample.
2. Dispersion: Disperse the sample by ultrasound or agitator.
3. Detection: Use laser particle size analyzer and other equipment for detection.
4. Data interpretation: Analyze the distribution of particles of different sizes.

Experimental control and data interpretation

In order to ensure the accuracy and reliability of the test results, it is very important to control the experimental conditions, such as ambient temperature, humidity, etc. In addition, data interpretation needs to consider factors such as equipment calibration and sample uniformity.

The introduction of these technical details is intended to help readers fully understand the quality inspection standards of polyacrylamide and provide guidance for the production and application of related industries.
