3、 Main uses
1. Basic raw materials for various modified polyacrylamide
For example, anionic polyacrylamide can be hydrolyzed by selecting different grades of non-ionic polyacrylamide as the basic raw material according to its use. Mannich cationic polyacrylamide is one of the most important basic raw materials.
2. Textile industry additives
Adding some other chemicals can be used to prepare chemical slurries for textile sizing, which can improve adhesion, permeability, and desizing performance, making textiles anti-static, reducing pulp spots, machine breakage rate, and debris. Therefore, it is a necessary chemical additive in the textile industry.
3. Can be used for sewage treatment
When the wastewater shows acidic suspension, non-ionic polyacrylamide is the most suitable flocculant. At this time, PAM plays an adsorption role, causing suspended particles to coagulate and precipitate, achieving the purpose of purifying water. It can also be used for drinking water treatment. This product is non-toxic, especially when used in combination with inorganic flocculants, it has the best water treatment effect.
4. Chemical grouting agent
Mixing 9.5 parts of non-ionic polyacrylamide with 0.5 parts of N, N-methylenediamine can be used as a chemical grouting agent for water blocking in embankments, foundations, tunnels, and other areas.
5. Sand prevention and fixation
Dissolve non ionic polyacrylamide into a solution with a concentration of 0.3%, then add a crosslinking agent and spray it on the desert to achieve waterproofing and water fixation. This method has the advantages of low usage, low cost, and convenience, making it one of the most effective methods for controlling deserts and preventing desertification.
6. Soil moisturizing agent
Non ionic polyacrylamide has strong hygroscopicity and can maintain soil moisture. In arid areas, using this product can improve soil.
7. Oilfield profile control and water plugging agent
The combination of non-ionic polyacrylamide and essential cellulose, combined with certain chemical additives, can be widely used for oilfield profile control.
