Production Method of HPEG 2400 Polycarboxylate Superplasticizer Monomer：

Prepare raw materials

The raw materials required for producing HPEG2400 polycarboxylate superplasticizer monomer mainly include polyether, acrylic acid, catalyst, crosslinking agent, etc. Polyether is the primary raw material for the production of polycarboxylate superplasticizers. Acrylic acid is one of the raw materials of the polymerization reaction and can be polymerized with polyether. The catalyst is the substance that accelerates the polymerization reaction. The crosslinking agent is an essential raw material to improve the molecular weight and properties of the polymer.

Polymerization reaction

In the polymerization reaction, polyether and acrylic acid are polymerized under the action of a catalyst to produce polycarboxylate. In the polymerization process, it is also necessary to add an appropriate amount of crosslinking agent to increase the molecular weight of the polycarboxylate and improve its performance.

Separation and purification

After the polymerization, it is necessary to separate the generated polycarboxylate from the reaction solution and purify it. Usually, the polycarboxylate is separated from the reaction liquid by precipitation, filtration, centrifugal separation, and then purified by washing, drying and other steps.

Deployment

In the production process, it is also necessary to adjust polycarboxylate according to market demand and product standards. Blending is to obtain a water-reducer product with the required properties. By adding the appropriate amount of additives, solvents or other raw materials, the water reduction rate, stability, retarding properties of the water reducer can be adjusted.

Packaging and storage

Finally, the prepared water reducer monomer is packaged and stored. Generally, containers with good sealing performance are used for packaging to avoid product deterioration and pollution. The storage environment should be kept dry, calm, and ventilated, avoiding direct sunlight and high temperatures.
