Polyaspartic Acid


Polyaspartic acid sodium is a water-soluble polymer. Therefore, it is an eco-friendly water therapy agent. In addition, sodium salt has several properties, such as non-phosphor, non-nitrogen, non-pollution, and complete biodegradation.

Polyaspartic acid sodium salt is a sodium salt of poly aspartic acid. It is a naturally degradable condensation polymer based on 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 for calcium carbonate is 100%.

Furthermore, poly aspartic acid sodium salt has dispersion and corrosion inhibition properties to metal devices. It is an option for phosphor-containing water treatment chemicals. To ensure that can stay clear of water system eutrophication and second pollution.

The sodium salt of polyaspartic acid is a type of biopolymer product. The molecules have plentiful amido bonds, carboxyl, and other active groups.

Amido peptide bond has organic activity and also high chemical stability. On the other hand, the amido peptide bond is very difficult to break down at high temperatures.

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

In each poly aspartic acid salt structural unit, the oxygen and nitrogen atoms can conveniently develop hydrogen bonds with water molecules because it has excellent hydrophilicity and solubility.

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

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

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

1. Water Treatment

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

2. Oil Drilling

Polyaspartic acid sodium is an excellent auxiliary in the oil field industry. It can be used as a 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 total biodegradation, the sodium salt of polyaspartic acid can be used as a brand-new water-softening active ingredient in popular home cleaning agent formulations. By the way, you can find it in disposable baby diaper ingredients.

4. Agriculture

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