What Is the Impact of the Ionicity of Cationic Polyacrylamide?

What is the impact of the ionicity of cationic polyacrylamide? The ionicity of cationic polyacrylamide is the charge density of polyacrylamide itself. It is a relative concept. The higher the charge density, the higher the ionicity. The ionicity determines the molecular chain length and price of cationic polyacrylamide.

Generally speaking, the molecular weight of cations with medium and high ionicity is not too long, that is, between 5 million and 11 million. However, products with higher ionicity will form tighter flocculates during sludge dehydration. Generally, if a filter press is used for sludge treatment, products with medium to high cationic ions should be used. This will not clog the filter cloth and form a tighter sludge cluster.

Precautions when using polyacrylamide

1. Use clean water to dissolve the flocculant, and make sure the water does not contain copper. (Generally, tap water can be used)

2. The equipment for dissolving medicine cannot be made of carbon steel, pig iron, or copper. It is recommended to use plastic, stainless steel, or those with anti-corrosion coating on the surface.

3. When dissolving the medicine, the medicine cannot be put into the medicine pool at one time. Water must be added first and then sprinkled evenly into the water.

4. When adding pam on site, be careful not to spill the medicine on the ground. If there is any spillage, please rinse it with plenty of water.
