   Polyaspartic Acid
Molecular formula  C4H6NNaO4
Chemical Formula HO(C4H205H2)NH
CAS NO 181828-06-8 25608-40-6
Properties Powder or liquid, commonly used is potassium or sodium. Is an artificial biomimetic synthetic, water-soluble polymer material, with features as phosphate-free, non-toxic, pollution-free and completely biodegradable properties, is an internationally recognized " green chemicals. Because of containing carboxyl peptide bond and other active groups, it has strong chelation, dispersion, adsorption effects, and excellent compatibility; it is widely used in fertilizer synergist; industrial cooling circulation water, reverse osmosis water, oil field injection water, metal cutting fluids, such as boilers and steam pipes do scale and corrosion inhibitor in water treatment; in the paper, printing and dyeing, washing industry can be used as dispersing agent; daily chemicals, etc.

Uses

1, the agriculture is dedicated Polyaspartic Acid as fertilizer synergist, is urea peptide, polypeptide compound fertilizer, controlled release fertilizer raw materials, can promote the grain, vegetables, fruits, flowers and other crops on the nutrient uptake and use of pesticides may also increase with efficacy. domestic and foreign research and application results show, Polyaspartic Acid as is the effect of plant nutrient absorption enhancers really, for a variety of plants and soil, and fertilizer used in conjunction with the performance in its main features:

Features one, reduce fertilizer loss, activation of nutrient elements, improve fertilizer efficiency, thereby reducing the amount of fertilizer 30%, 10% -30% increase in production.

Features two, to promote crop of iron, zinc, manganese and other trace elements to absorb, use Polyaspartic Acid-treated crops, compared with the control plants 3-4 times higher than trace levels.

Features three, to promote crop early 7-10 days, 10-15 days to extend the harvest period.

Features four, to promote root growth, enhanced stress resistance.

 

2, the industry-specific Polyaspartic Acid, widely used in industrial circulating cooling water, reverse osmosis water, oil field injection water, metal cutting fluids, such as boilers and steam pipes do scale and corrosion inhibitor in water treatment; in the paper, printing and dyeing, washing industry can be used as dispersants. Polyaspartic Acid hard in high degree, high-alkali degree, high PH value, high concentration of excellence, and its scale is better than the common phosphine inhibitors. using this water instead of phosphine treatment agent, to avoid eutrophication of water bodies and emission of secondary pollution.


Packing

Liquid: plastic drum, Net wt 25kg or 250kg; Solid: bag. It should be kept in ventilating place, the storage period is ten months.
