Polyacrylamide (PAM) is one of the most important industrial polymers and is used in numerous industries, including water treatment, oil and gas, agriculture, paper and textile industries. This polymer is of particular interest due to its unique properties such as gelation, viscosity and coagulation. The production of polyacrylamide powder requires a complex process that must be carefully carried out to achieve a high-quality final product. This article describes processes for the production of polyacrylamide powder.
Commodities
Acrylamidmonomer
Acrylamide monomer is one of the main raw materials for the production of polyacrylamide.Acrylamide is a colorless, crystalline chemical substance and the main raw material in its production.
Motivator
Various catalysts such as peroxides, azo compounds and photocatalysts are used to initiate the polymerization process. These catalysts play an important role in the speed and efficiency of polymerization .
Solvent
Some production processes use solvents such as water, alcohol, and organic solvents to dissolve monomers and catalysts. Solvents play an important role in controlling the quality of the reaction and the final product.
Production
Block copolymerization
In this process, acrylamide monomers are polymerized in pure form without solvents. The polymerization reaction takes place under the influence of a catalyst and temperature. The result of the reaction is a polyacrylamide block, which is then ground into powder.
Vergangenheit
- Vorbereitung der Rohstoffe : Mischen von Acrylamidmonomer mit Katalysator.
- Einleitung der Polymerisation : Die Mischung aus Monomeren und Katalysator wird unter Bedingungen gebracht, die für die Einleitung der Polymerisationsreaktion geeignet sind.
- Reaktionsende : Nach Abschluss der Reaktion werden Polyacrylamidblöcke erhalten.
- Trocknen und Mahlen : Polyacrylamid wird getrocknet und dann zu Pulver gemahlen.
Lösungspolymerisation
Bei dieser Methode wird Acrylamidmonomer in einem Lösungsmittel gelöst und mithilfe eines Katalysators polymerisiert. Durch diese Reaktion entsteht Polyacrylamid in Lösung, das anschließend getrocknet und zu Pulver verarbeitet wird.
Past
- Dissolving the monomer : Dissolve the acrylamide monomer in a solvent such as water or alcohol.
- Catalyst addition : A suitable catalyst is added to the monomer solution.
- Initiation of polymerization reaction : Bring the monomer and catalyst solution under conditions suitable for initiating the polymerization reaction.
- End of reaction : After completion of the reaction , a polyacrylamide solution is obtained.
- Drying and grinding : The polyacrylamide solution is dried and then ground into powder.
Suspension polymerization
In this process, acrylamide molecules are polymerized in a non-polar medium, such as oil, and the molecules are suspended in the medium in the form of small droplets and then polymerized by a catalyst. Once the reaction is complete, polyacrylamide is formed in the form of small particles, which are then dried and processed into powder.
Past
- Monomer Suspension : Acrylamide monomer is suspended in the form of fine droplets in a non-polar medium.
- Catalyst addition : A suitable catalyst is added to the monomer suspension.
- Initiation of polymerization : The monomer and catalyst suspension is placed under conditions suitable for the initiation of the polymerization reaction.
- End of Reaction : After completion of the reaction, fine polyacrylamide particles are obtained.
- Drying and grinding : Polyacrylamide granules are dried and then ground into powder.
