Sodium Polyacrylate (PAAS) is a water-soluble polymer with the following characteristics and applications:

Non toxicity: PAAS is human and environmentally friendly and is considered non-toxic.

High water solubility: It can completely dissolve in water, forming a transparent or semi transparent solution..

Anti scaling performance: Under alkaline and moderate concentration conditions, PAAS can prevent scaling because it can stabilize particles in water and prevent them from depositing and forming a scale layer..

Dispersion: PAAS can disperse microcrystals or sediments of salts such as calcium carbonate and calcium sulfate in water, preventing their precipitation, which is very important in water treatment.

Industrial Applications: As an efficient dispersant, PAAS is widely used in multiple industrial fields, including:

    Power plants, chemical plants, fertilizer plants, and refineries: PAAS is used as a scale inhibitor and dispersant in the circulating cooling water systems of these industries to reduce equipment scaling and improve heat exchange efficiency..

    Air conditioning system: In the air conditioning system, it can also prevent scaling of cooling water..

Other industry applications:

    Paper industry: PAAS can be used as an additive in the papermaking process to improve the stability of pulp and the quality of paper..

    Textile and Printing and Dyeing: In these industries, PAAS can be used as a dyeing aid to improve dyeing uniformity and color fastness..

    Ceramic Industry: PAAS can be used as a dispersant in the manufacturing process to improve the uniformity of raw materials..

    Coating Industry: PAAS can improve the stability of coatings and the performance of coatings..

    Building materials industry: PAAS can be used as an additive in certain construction products to improve material performance..

These characteristics of PAAS make it an indispensable chemical in industrial water treatment and various industrial applications.

Polyacrylic acid (PAA)
CAS No.: 9003-01-4
Performance and Application

[PAA][2] is a non-toxic substance that is easily soluble in water

[Polyacrylic][3] can operate under alkaline and moderate concentration conditions without scaling.

It can disperse microcrystals or sediment of salts such as calcium carbonate and calcium sulfate in water, prevent precipitation, and achieve the purpose of scale inhibition.

As a commonly used dispersant, it is widely used as a scale inhibitor and dispersant in the circulating cooling water systas of power plants, chaical plants, fertilizer plants, refineries, and air conditioning systas.

It is also used in industries such as papermaking, textiles, printing and dyeing, ceramics, coatings, and building materials.

Customized services

The company can customize products with different molecular weights and solid contents according to customer needs, such as 45% and 60% polyacrylic acid.
usage method

PAA is usually used in combination with other water treatment agents, and the specific formula and dosage need to be determined through experiments based on the on-site water quality and equipment materials.
If used alone, the general concentration is 1-15mg/L.
When used in other industries, such as concrete water reducers, printing and dyeing, the dosage should be determined based on experiments.
Packaging and Storage

Packaged in plastic drums, each weighing 25kg or 200kg, or determined according to user needs.
It should be stored indoors in a cool and shady place, with a storage period of twelve months.
safety protection

PAA is weakly acidic, and appropriate labor protection equipment should be worn during operation to avoid contact with skin and eyes.
Immediately rinse with plenty of water after contact.
