1.Chemical name: Poly Acrylamide (PAM) 2. CAS: 9003-05-8 3.Performance:White crystal 4. Application: polyacrylamide (PAM) is one of the most widely used water-soluble polymers. It is widely used in oil exploitation, papermaking, water treatment, textile, medicine, agriculture and other industries. There are three forms of polyacrylamide products: aqueous colloid, powder and emulsion. According to the characteristics of ions, it can be divided into four types: non-ionic, anionic, cationic and amphoteric. 5. Methods of use: before use, prepare the product with deionized water to a solution of 2-5 thousandth of molecular weight according to the proportion of use. In the process of configuration, the agitation should not be too intense, so as to prevent the polymer chain of the product from breaking due to the shear action and affect the use effect of the product. The prepared product solution should be prepared and used first, and the storage time should not exceed 24 hours. The simulated screening in the laboratory can determine the approximate dosage of the product, but it is necessary to adjust the super final dosage according to the site conditions. V. packaging and storage: kraft paper bag for external use, with plastic film package inside, net weight of each bag is 25kg, which can also be modified according to the user's requirements. The product is hygroscopic and should be stored in a cool and dry place with temperature lower than 35 ºC. Solid products shall not be scattered on the ground to prevent the ground from sliding after the product absorbs moisture. 6. Safety protection: pay attention to labor protection during operation, and avoid contact with skin, eyes, etc. 7.
