In my country's industry standards, the national industry standards for polyacrylamide include GB17514-2008, cationic polyacrylamide GB/T31246-2014, anionic polyacrylamide GB17514-2008 and non-ionic polyacrylamide GB17514-2008. anionic polyacrylamide suppliers You will find that the national industry standard of polyacrylamide, anionic polyacrylamide and non-ionic polyacrylamide are the same, only cationic polyacrylamide is separate.
From the national industry standard of polyacrylamide, we can find the difference of cationic polyacrylamide.
In fact, the difference between cationic polyacrylamide, anionic polyacrylamide and non-ionic polyacrylamide is mainly reflected in:
- Different ion models and specifications
Cationic, anionic and non-ionic are three different types of polyacrylamide products.
- Different specifications and models
In the national industry standard of cationic polyacrylamide, the specifications and models can be simply divided into 15 types: 5, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70; if according to the molecular weight Different specifications and models can be simply divided into three types: 800, 10, 12 million molecular weight; if the specifications are divided by solid content, they can be simply divided into: ≤88%, >88%, 90%, etc. wholesale polyacrylamide In addition, there are ways to differentiate between water-insoluble chemicals and residual individual.
In the national industry standard of anionic polyacrylamide, the specifications and models are mainly based on the molecular weight: 6-18 million; solid content 80-92%, etc.
In the national industry standard of non-ionic polyacrylamide, the specifications and models are mainly based on the molecular weight difference of 4-12 million.
- The main purpose is different
The application of cationic polyacrylamide described in the national industry standard mainly has two aspects: organic sewage treatment and sludge treatment.
The application of anionic polyacrylamide described in the national industry standard is mainly to resolve inorganic wastewater.
The main uses of non-ionic polyacrylamide described in the national industry standards are mainly to solve inorganic wastewater and acid wastewater.
