According to the ion type, polyacrylamide can be divided into: anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide.
How does the polyacrylamide manufacturer identify the type of polyacrylamide ion:
Polyacrylamide manufacturers are equipped with professional laboratories. In addition to testing the technical indicators of daily products, laboratory work also needs to test external samples. Normally, when receiving an external sample, the ion type of the product must be detected first. So how to distinguish the ion type? The answer is: the technical indicators for detecting foreign samples. Anionic polyacrylamide and non-ionic polyacrylamide are distinguished by detecting the degree of hydrolysis. The degree of hydrolysis of anionic polyacrylamide is around 25, and the degree of hydrolysis of non-ionic polyacrylamide is around 5. Cationic polyacrylamide is distinguished by detecting the ion degree, and the ion degree of dry powder products usually fluctuates between 10-60.
How to identify the type of polyacrylamide ion through a simple experiment:
How to distinguish the ion type of polyacrylamide when the staff is in the after-sales site or does not have the experimental equipment? First, we need to have samples of anionic polyacrylamide and cationic polyacrylamide, and dissolve these two products separately for use. Then dissolve the product that needs to detect the ion type, and distinguish it through the yin and yang reaction. Pour the dissolved anionic polyacrylamide solution into the product solution to be tested. If a large amount of white flocs appear, it means that the tested sample is cationic polyacrylamide. If there is no reaction, it means that it is non-ionic or anionic. Then identify by the cationic polyacrylamide solution, a small amount of flocs indicate that the tested product is non-ionic polyacrylamide, and a large amount of flocs indicate that the tested sample is anionic polyacrylamide.
The importance of identifying the type of polyacrylamide ion:
When you don’t know what product is being used for flocculation on site, identifying the type of polyacrylamide ion can help users quickly screen for models and find products that match the on-site wastewater more quickly.
Learn to identify the type of polyacrylamide ion, so that users can better understand the product, use the product with better product properties, be aware of it, and beware of bad suppliers deceiving consumers
