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 makePASPhave high chemical activity in aqueous solution; in each structural unit ofPASP, the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, it has good hydrophilicity and water solubility. The special molecular structure ofPASPensures that it has good dispersing ability, corrosion inhibiting properties, excellent biodegradability and environmental friendly characteristics.Specification:ItemsIndexAppearanceYellow to umber liquidSolid content %40.0 minDensity (20)g/cm31.2 minpH(1% water solution)9.0-11.0Usage:According to different molecular weights of PASP, it can be used in water treatment, agriculture and forestry, petroleum exploitation, detergents and other fields.I. Water treatment1. PASPhas 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, PASP 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.2. PASPhas good scale inhibition on CaCO3、CaSO4、BaSO4、Ca3(PO4)2,etc. Its scale inhibition rate for CaCO3is 100%.3. PASPis an alternative of phosphor-containing Water Treatment Chemicals and has better scale inhibition effects.PASPcan avoid eutrophication and second pollution in water system.II. Agriculture and Forestry1. PASPcan be used as fertilizer synergist in agriculture. Adding it into urea can improve fertilizer efficiency by 20-40% and reduce the fertilizer dosage;2. AddingPASPin 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;3. PASPcan improve the nutrient absorption of grain, vegetable, melon and fruit, and flowers, promote root growth, increase crop yields, enhance plants and its stress resistance;4. PASPcan be used with phosphorodithioate and other pesticides to enhance pesticide effect, crop yields and improve crop quality;5. PASPcan 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 exploitation1. PASPcan 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;2. PASPwith molecular weight around 10000 can reduce fluid viscosity. In bentonite mud, when the dosage of PASP is 0.4%, the viscosity reduction rate can be over 70%;3. It has good resistance to salt and calcium;IV. Detergents1. PASPhas 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;2. 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 ApplicationsBecause of its good dispersion to inorganic and organic compouds,PASPhas been applied with different degree in pharmaceuticals, pigments, paints, leather, inorganic chemicals, oilfield chemicals and other fields.PASPis 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 fromPASPhas been widely used in family planning, anti-tumor drugs making etc.Package and Storage:200L plastic drum,IBC(1000L),customers requirement.
