The oil pollution, organic, inorganic, sewage, complex sewage treatment. In the sewage system with an irregular pH, the use of a single ion polyacrylamide is far less than the synergistic effect of bisexual ions. If the cedic polyacrylamide and the anion polyacrylamide are used, the reaction will cause precipitation. So the two -sex ion products are the ideal. Idded in sludge dehydration. It for papermaking additives.
Polyacrylamide: Polyacrylamide (PAM) is a water -soluble polymer. It is insoluble in most organic solvents. It has good flocculation and can reduce the friction resistance between liquid. Popular ions, cations and two -sex types: four types. (Note: Polyacrylamide is different from acrylamide) The polyacrylamide is called No. 3 condenser; polyacrylamide is divided into anion polyacrylamide, cations polyacrylamide, non -ionic polyacrylamide, bisexual ion polymerization Acrylamide. Prilaterality: PAM polyacrylamide is a water -soluble linear polymer that is polymerized by the liberal radicals of acrylamide (AM) monomer. It has good flocculation and can reduce the between liquid The friction resistance can be divided into four types: non -ions, pine ions, cations, and bonus.聚丙烯酰胺（PAM）不溶于大多数有机溶剂，如甲醇、乙醇、丙酮、 乙醚、脂肪烃和芳香烃，有少数极性有机溶剂除外，如乙酸、丙烯酸、氯乙酸、乙二醇、甘油、 Plus urea and telamide. However, the solubility of these organic solvents often needs to be heated, otherwise there is not much application value. In suitable low concentrations, the polyacrylamide solution can be regarded as a mesh structure, and the tangling of the chain machinery and the hydrogen bonding together form a mesh node; when the concentration is high Points make the PAM solution gel. PAM aquatic solution has good compatibility with many organic objects that can be soluble with water. It has good compatibility with electrolytes. Sodium, sodium phosphate, sodium sulfate, zinc chloride, boric acid, and phosphate are not sensitive. The number of polyacrylamide: The number of mesh refers to the particle size or thickness of the material, the number of mesons in the unit area is the number of squares in the unit area. Generally, it is defined. Number, the number of mesh of the screen. For example, 600 mesh is 600 square mesh per square meter, and the number of polyacrylamide is 20 meters to 80 mesh, which is between 0.85mm ~ 0.2mm. The meter size of the polyacrylamide can be controlled at about 100 mesh. The larger the polyacrylamide, the more likely it is to dissolve. The polyacrylamide (PAM) is a water -soluble polymer. It is insoluble in most organic solvents. It has good flocculation and can reduce the friction resistance between liquid. Apdotic market operations in my country's polyacrylamide (PAM) industry with the continuous expansion of the operating demand market in my country's polyacrylamide (PAM) industry have ushered in a new development opportunity. The polyacrylamide is white powder or small granules, with a density of 1.32g/cm3 (23 degrees), a glassized temperature of 188 degrees, and a soft temperature of nearly 210 degrees. Generally, it contains a small amount of water when drying. When dry, it will quickly absorb water from the environment. The commonly separated polymer separated by the frozen drying method is white and soft non -crystalline solid. Polyacrylamide PAM is a crispy white solid. Drying of commodity polyacrylamide is usually dried under moderate conditions. Generally, the water content is 5 to 15 %. , Is a transparent, hard and fragile solid.
