PASP

 

Sodium of Polyaspartic Acid (PASP)
(CAS No.:181828-06-8, 34345-47-6)
 Potassium of Polyaspartic Acid (PASP)
(CAS No.: 64723-18-8)
 
PASP is a green water treatment agent, with properties of non-phosphor, non-nitrogen, non-pollution and biodegradation.
 
Scale inhibition mechanism of PASP is that it can destroy the crystal structure of scale such calcium carbonate, calcium phosphate, etc and make the scale soft. The softness of scale is higher than the existing polyacrylic acid, poly phosphoric acid scale inhibitors, etc. PASP can form the chelate with calcium, magnesium, copper, iron and other ions, attaching to the surface of the metal container to prevent metal corrosion. It is a kind of excellent corrosion inhibitor.
 
Many research reports suggest that PASP has good thermal stability and scale inhibition performance and little dosage.
 
So PASP is a kind of water treatment chemicals which can be used in high temperature, high calcium ion concentration water systems.
 
PASP can be used in agricultural as nutrient absorption intensifier to improve the production of vegetable, melon and fruit, and flowers more than 15%, even up to 70%. When used together with pesticide, its effects will be improved.
