Production technology of kneeling polyacrylamide

There are three production processes of polyacrylamide: aqueous solution polymerization, inverse emulsion polymerization and radiation initiation. The most recommended one: aqueous solution polymerization.

Is a traditional method for producing polyacrylamide. Polyacrylamide colloid and powder products can be produced by this method. Generally, polyacrylamide colloid is obtained by direct polymerization of 8%- 10% acrylamide aqueous solution under the action of initiator; Polyacrylamide dry powder is polymerized with 25%-30% acrylamide solution, and the polyacrylamide colloid obtained after polymerization is granulated, kneaded, dried and crushed to obtain the product. Aggregation is the key process. This method has the characteristics of safe production, simple process equipment and low production cost, and has been widely used in polyacrylamide production at home and abroad. In China, this method was first used to produce polyacrylamide by manual disc polymerization, and then used in kneader. In the late 1980s, the conical kettle polymerization process was developed and successfully tested in Jiangdu Chemical Plant, where the fifth nuclear industry department is located. The polymerization technology introduced from abroad in the 1990s is similar to the domestic technology except that the reactor can rotate and its volume is larger.
