anionic polyacrylamide of magnafloc LT27 LT25 LT20 lT27AG can be replaced by Chinafloc A2517-PWG
Polyacrylamide is one of the very popular water purification flocculant products, whether anionic or cationic, plays an important role in industrial production and life, a friend asked me, there is no anionic polyacrylamide used in the water plant? Drinking water grade and food grade PAM you know? Today I will tell you about this special anionic polyacrylamide product:
First of all, whether it is the water plant or food processing use, the molecular weight of this anionic polyacrylamide is 18 million, of course, a friend will say, the industrial grade also has 18 million ah, industrial grade can be used in the water plant and food processing? Here we need to pay special attention to one point: can not be used, the water plant is the people's livelihood project, related to the health of the people, can be used in the water plant PAM needs to have special requirements.
Secondly, the important point is that food grade and drinking water grade polyacrylamide residues, that is, the residual monomer content of acrylamide, industrial grade products in two thousand, and drinking water treatment indicators need to reach five thousand below, this is the important difference between industrial grade anion and food grade anion PAM.
The price of industrial grade anion is 15,000, while the price of food grade polyacrylamide is 28,000, which is also the difference between the two products. After all, food grade products are more secure.
It is because of the huge price gap between industrial grade and food grade PAM, therefore, when you buy products, you need to paint bright eyes, above we have said, molecular weight and other indicators are no difference, the main difference is in the residual monomer content above.
Of course, since there is a demand for food grade drinking water grade products, there are such high technical indicators, then there will be water-related products of health approval, we will not judge anionic polyacrylamide industrial grade or food grade, no relationship, as long as the purchase of products issued by the Department of health water-related approval can be.
