Product Advantage:
PASPA is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASPA have high chemical activity in aqueous solution; in each structural unit of PASPA, the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, it has good hydrophilicity and water solubility. The special molecular structure of PASPA ensures that it has good dispersing ability, corrosion inhibiting properties, excellent biodegradability and environmental friendly characteristics.
Product Use:
According to different molecular weights of PASPA, it can be used in water treatment, agriculture and forestry, petroleum exploitation, detergents and other fields. I. Water treatment
PASPA has characteristic of polyanion surfactant, which can be chelated with magnesium, copper, iron, cobalt and other polyvalent metal ions after hydrolysis. It has excellent scale inhibition and dispersion properties. As scale and corrosion inhibitor, PASPA is widely used in industrial circulating water, boiler water, reverse osmosis water, oil recycled water, desalination water treatment, especially for water treatment systems of high hardness, high alkalinity, high pH and high concentration.
PASPA has good scale inhibition on CaCO3, CaSO4, BaSO4, Ca3(PO4)2 ,etc..
PASPA is an alternative of phosphor-containing Water Treatment Chemicals and has better scale inhibition effects. PASPA can avoid eutrophication and second pollution in water system.
II. Agriculture and Forestry
PASPA can be used as fertilizer synergist in agriculture. Adding it into urea can improve fertilizer efficiency by 20-40% and reduce the fertilizer dosage;
Adding PASPA in the production process for fertilizer can increase fertilizer granulation level, increase the number of standard particles to 97%, thereby enhancing the rate of finished products and reduce loss;
PASPA can improve the nutrient absorption of grain, vegetable, melon and fruit, and flowers, promote root growth, increase crop yields, enhance plants and its stress resistance;
PASPA can be used with phosphorodithioate and other pesticides to enhance pesticide effect, crop yields and improve crop quality;
PASPA can form complex with heavy metals in the soil, displace heavy metals from the soil, in order to achieve the purpose of restoration of soil pollution.
III. Petroleum exploitation
PASPA can form chelation with calcium, magnesium, copper, iron and other metal ions to attach to the metal surface of the container to prevent metal corrosion. It is an excellent corrosion inhibitor, especially for preventing oil pipeline corrosion caused by carbon dioxide;
PASPA with molecular weight around 10000 can reduce fluid viscosity. In bentonite mud, when the dosage of PASPA is 0.4%, the viscosity reduction rate can be over 70%;
It has good resistance to salt and calcium;
IV. Detergents
PASPA has characteristics of anionic surfactant and good chelation, dispersion properties. It can soften water, dispersing, anti-fouling, and prevent re-contamination of the greasy dirty off the clothes during the washing process;
It can be adsorbed on the surface of dinnerware, prevent mouldy, resulting in better cleaning effect. It is an important component of dishwashing detergent for cleaning of hard surfaces;
V. Other Applications
Because of its good dispersion to inorganic and organic compouds, PASPA has been applied with different degree in pharmaceuticals, pigments, paints, leather, inorganic chemicals, oilfield chemicals and other fields.PASPAis called ""third-generation polyurea"", it can be used to produce protective coatings of high weather resistance, high resistance to chemical corrosion, fast-curing paint, and applied directly to fast curing coatings on the metal substrate and industrial flooring, etc., ; it can be used in the tanning process as tanning agents, produces biodegradable leather; pharmaceutical carrier material made from PASPA has been widely used in family planning, anti-tumor drugs making etc.
