Detailléiert Aféierung 

 

CAS Nr. 181828-06-8，35608-40-6 Molekulare Gewiicht: 1000-5000

Molekulare Formel: C₄H₅NEE₃M(C₄H₄NEE₃M)m(C₄H₄NEE₃M)nC₄H₄NEE₃M₂         

Strukturell Formel:

Eegeschaften:

PASP ass eng Aart vu Biopolymermaterialien, vun deenen d'Moleküle reichend Amidobindung, Carboxyl an aner aktiv Gruppen enthalen. Amido Peptidbindung huet biologesch Aktivitéit an héich chemesch Stabilitéit, schwéier bei héijer Temperatur ze zersetzen; Carboxylgrupp ka komplex sinn mat ville Metallionen am Waasser, déi maachen PASP hunn héich chemesch Aktivitéit an wässerlecher Léisung; an all strukturell Eenheet vun PASP, Sauerstoff a Stickstoffatome kënne ganz einfach Waasserstoffbindunge mat Waassermoleküle bilden, et huet gutt Hydrophilizitéit a Waasserléislechkeet. Déi speziell molekulare Struktur vun PASPgarantéiert datt et gutt Dispergéierungsfäegkeet, Korrosiounshemmungseigenschaften, exzellent biologesch Ofbaubarkeet an ëmweltfrëndlech Charakteristiken huet.

Spezifizéierung:

Benotzung:

Geméiss verschiddene Molekulargewichte vu PASP kann et a Waasserbehandlung, Landwirtschaft a Bëschaarbecht, Petroleumexploitatioun, Detergenten an aner Felder benotzt ginn.

I. Waasser Behandlung

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, Fall₄, BaSO₄, Ca3(PO₄)₂ ,usw..

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. Landwirtschaft a Bëschaarbecht

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 Ausbeutung

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. Et huet gutt Resistenz géint Salz a Kalzium;

IV. Wäschmëttelen

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. Et kann op der Uewerfläch vum Iessen adsorbéiert ginn, vermeit schimmel, wat zu engem besseren Reinigungseffekt resultéiert. Et ass e wichtege Bestanddeel vum Spullmëttel fir d'Botzen vun haarde Flächen;

V. Aner Uwendungen

Wéinst senger gudder Dispersioun op anorganesch an organesch Verbindungen, 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 a Lagerung:

200L Plastikstrommel, IBC(1000L), Ufuerderung vum Client. Lagerung fir zéng Méint am schatteg Raum an dréchen Plaz.

Sécherheet Schutz:

PASP ass alkalesch, oppassen op Aarbechtsschutz beim Operatioun, vermeiden Kontakt mat Haut, Aen, asw., Spülen mat vill Waasser nom Kontakt.
