Polyacrylamide (PAM) is a general term for acrylamide homopolymer or polymers obtained by copolymerization with other monomers. It is one of the commonly used varieties of water-soluble polymers. Because the polyacrylamide structural unit contains amide groups, it is easy to form hydrogen bonds, so that it has good water solubility and high chemical activity, and is easy to undergo grafting or cross-linking branched or network-shaped modified products. It is widely used in petroleum exploration, water treatment, textile, papermaking, mineral processing, and agriculture and other industries, and is known as “Auxiliary Agents for All Industries”. The main application areas abroad are water treatment, papermaking, mining, metallurgy, etc.; at present, the largest domestic consumption is in the field of oil production, and the rapid increase in consumption is in the field of water treatment and papermaking.

Production process: There are two main types: high-pressure tube method and kettle method. For the reaction temperature and pressure, the tubular process generally uses low-temperature high-activity primers to initiate polymerization, with high purity as the main raw material, propylene/propane, etc. as density agents, and high-activity initiators at about 200℃～330℃, The polymerization reaction is carried out under the conditions of 150-300MPa. The molten polymer that initiates polymerization in the reactor must be cooled and separated under high pressure, medium pressure and low pressure. The high pressure circulating gas is cooled and separated and then sent to the inlet of the ultra-high pressure 300 MPa compressor. The medium pressure circulating gas is cooled and separated. It is sent to the inlet of the high-pressure 30 MPa compressor, and the low-pressure circulating gas is cooled and separated and then sent to the low-pressure 0.5 MPa compressor for recycling. When granulating, the company can add appropriate additives according to different application fields, and the granules are packaged and shipped out of the factory. Allergic to sound, allergic reaction to sound, intermittent soreness, illness, dermatitis, etc. Eat more beans, cereals, hard fruits, fruits, milk and green leafy vegetables.
