Polyaspartic Acid


Polyaspartic acid sodium is a water-soluble polymer. It is an eco-friendly water therapy agent. The sodium salt has several properties. Such as non-phosphor, non-nitrogen, non-pollution and also completely biodegradation.

Polyaspartic acid sodium salt is a sodium salt of poly aspartic acid. It is a naturally degradable condensation polymer based upon the amino acid aspartic acid.

Polyaspartic acid sodium salt has excellent scale restraint on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, and so on. The scale inhibition rate to calcium carbonate is 100%.

Furthermore, polyaspartic acid sodium salt has dispersion and also corrosion inhibition properties to metal devices. It is an option of phosphor-containing water treatment chemicals. To make sure that can stay clear of water system eutrophication and also the second pollution.

Sodium salt of polyaspartic acid is a type of biopolymer product. The molecules have plentiful amido bond, carboxyl, as well as various other active groups.

Amido peptide bond has organic activity and also high chemical stability. The amido peptide bond is very difficult to break down at high temperatures circumstances.

The carboxyl group can complex with numerous metal ions in water. That makes poly aspartic acid sodium salt has high chemical activity in a liquid solution.

In each structural unit of poly aspartic acid salt, the oxygen and also nitrogen atoms can conveniently develop hydrogen bonds with water molecules. Because it has great hydrophilicity as well as water solubility.

The special molecular structure makes sure it has excellent dispersing capability. And also corrosion preventing properties, outstanding biodegradability, and environment-friendly.

This polymer can be synthesized in an eco-friendly method. It is biodegradable. Therefore polyaspartic acid sodium is a green alternative to numerous products.

Additionally, poly aspartate sodium also can be used as a naturally degradable anti-scaling agent as well as a corrosion inhibitor. Since it has outstanding water-solubility and capability to chelate metal ions.

1. Water Treatment

Engineers utilize it as an antiscale and also corrosion prevention in the high hardness, high alkalinity, high ph-value, high-concentration multiple systems. Such as commercial circulating cool water system, central heating boiler water, oilfield water, and also reverse osmosis water.

2. Oil Drilling

Polyaspartic acid sodium is an excellent auxiliary in the oil field industry. It can be used as thinner for oil drilling liquid and scale corrosion inhibitor in the reinjection water pipeline.

3. Daily Chemical

Because of its features of non-phosphorus and totally biodegradation. The sodium salt of polyaspartic acid can be used as brand-new water softening active ingredient in the popular home cleaning agent formulations. By the way, you can find it in disposable baby diapers ingredients.

4. Agriculture

When added in a variety of fertilizers, poly aspartic acid sodium can promote the roots’ growth and plant adsorption for N, P, K ratios. So it can increase the usage ratio of fertilizers and the crop yield.
