Molecular Formula: C₄H₅AIHWA₃M(C₄H₄AIHWA₃M)m(C₄H₄AIHWA₃M)nC₄H₄AIHWA₃M₂         

Structural Formula:

Properties:

PASP imhando yezvigadzirwa zvebiopolymer, izvo mamorekuru ane akawanda amido bond, carboxyl uye mamwe mapoka anoshanda. Amido peptide bond ine biological chiitiko uye yakakwira makemikari kugadzikana, yakaoma kuora pakupisa kwakanyanya; boka re carboxyl rinogona kuomarara neayoni akawanda esimbi mumvura, anoita PASP kuva nemakemikari akakwirira mukugadzirisa kwemvura; muchikamu chega chega chechimiro che PASP, maatomu eokisijeni nenitrogen anogona nyore kuumba hydrogen zvisungo nemamorekuru emvura, ine yakanaka hydrophilicity uye kunyungudika kwemvura. Iyo yakakosha molecular chimiro che PASPinova nechokwadi chekuti ine kugona kuparadzira kwakanaka, corrosion inhibiting properties, yakanakisa biodegradability uye zvakatipoteredza zvine hushamwari hunhu.

Tsanangudzo:

Kushandisa:

Zvinoenderana nehuremu hwakasiyana hwePASP, inogona kushandiswa mukurapa kwemvura, kurima uye masango, kushandiswa kwepetroleum, detergents nemimwe minda.

I. Kugadziriswa kwemvura

1. PASP 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, 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. PASP has good scale inhibition on CaCO₃, Nyaya₄, BASO₄,Ca3(PO₄)₂ , nezvimwewo..

3. PASP is an alternative of phosphor-containing Water Treatment Chemicals and has better scale inhibition effects. PASP can avoid eutrophication and second pollution in water system.

II. Zvekurima neMasango

1. PASP can be used as fertilizer synergist in agriculture. Adding it into urea can improve fertilizer efficiency by 20-40% and reduce the fertilizer dosage;

2. Adding PASP 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;

3. PASP 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;

4. PASP can be used with phosphorodithioate and other pesticides to enhance pesticide effect, crop yields and improve crop quality;

5. PASP 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 kushandiswa

1. PASP 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;

2. PASP with 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. Iine kupikisa kwakanaka kune munyu uye calcium;

IV. Detergents

1. PASP 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;

2. Inogona kuve adsorbed pamusoro pe dinnerware, kudzivirira kuumbwa, zvichikonzera zvirinani kuchenesa maitiro. Icho chikamu chakakosha che dishwashing detergent yekuchenesa nzvimbo dzakaoma;

V. Zvimwe Zvikumbiro

Nekuda kwekupararira kwayo kwakanaka kune inorganic uye organic compouds, PASP has been applied with different degree in pharmaceuticals, pigments, paints, leather, inorganic chemicals, oilfield chemicals and other fields.PASP is 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 PASPhas been widely used in family planning, anti-tumor drugs making etc.

Package uye Kuchengeta:

200L epurasitiki chigubhu, IBC (1000L), zvinodiwa nevatengi. Kuchengeta kwemwedzi gumi mukamuri ine mumvuri uye munzvimbo yakaoma.

Kuchengetedzwa Kwekuchengetedza:

PASP ine alkaline, teerera kudzivirira kwevashandi paunenge uchishanda, dzivisa kusangana neganda, maziso, nezvimwewo, sukurudza nemvura yakawanda mushure mekusangana.
