SINOFLOC superabsorbent polymers (known as SAP) are water insoluble polymer, cross-linked copolymer of acrylic acid. It can absorb water which is hundreds to thousands of times heavier than its own, and it has excellent water retention. Once the absorbed water is expanded into a hydrogel, it is difficult to separate the water even when it is pressed. Therefore, it is widely used in personal hygiene products, industrial and agricultural production, civil construction and other fields. Because of the strong water absorption capacity and excellent water retention property, the Water Insoluble Polymer absorbent is widely used in agriculture and forestry fields as the soil water retention agent. China is lack of water resources. Therefore, the application of water retaining agent becomes more and more important. Currently in domestic, Water Insoluble Polymer (SAP) products have been used for many kinds of plants in the fields such as grain, cotton, oil, sugar, tobacco, fruit, vegetables, f...

With the continuous development of science and technology, the appearance of diapers, sanitary pads and other products has provided more advanced health protection. In the beginning, diapers only can prevent leakage and absorb urine, but now it not only can prevent leakage and ventilate but also can absorb urine and prevent bacteria. So, it is favored by mothers. How to lock the moisture in the diapers? Because SAP (superabsorbent) is a kind of macromolecule compound. Diapers SAP absorbent material is a kind of macromolecule compound. When SAP suck more hundreds to thousands of times of water as its own weight, water won't be leak out, and it has a strong water retention ability, so it is also known as super absorbent polymer or water retaining agent. SINOFLOC superabsorbent polymers (known as SAP) are water insoluble polymer, cross - linked copolymer of acrylic acid. In contact with water, by capillary action and diffusion, the water molecules penetrate into the resin and the i...

The amphoteric polyelectrolyte is a kind of polyacrylamide with product chain not only the carboxyl anion charge, but also the vinyl cation charge. Therefore, an irregular copolymer of zwitterionic ions with both positive and negative charges on the molecular chain is formed. Amphoteric polyacrylamide is formed by hydrolysis and copolymerization of cationic and anionic groups. The advantage is that it has the characteristics of general cationic flocculants. It is used to extract ore from strong acid or recover valuable metals from acidic catalyst containing metal. Zwitterionic type is not a mixture of anionic and cationic type. If the combination of cationic polyacrylamide and anionic polyacrylamide is used, it will react to precipitate. So the bisexual ion product is the most ideal. Zwitterionic polyacrylamide, because of its cationic group and anion group, has the characteristics of general cationic flocculants. The combination of cationic polyacrylamide and anionic polyacrylamide...
