Natriumsalt af polyasparaginsyre (PASP)

Detaljeret introduktion 

 

CAS-nr. 181828-06-8，35608-40-6 Molekylvægt: 1000-5000

Molekylær formel: C₄H₅INGEN₃M(C₄H₄INGEN₃M)m(C₄H₄INGEN₃M)nC₄H₄INGEN₃M₂         

Strukturel formel:

Ejendomme:

PASP er en slags biopolymermaterialer, hvoraf molekyler indeholder rigelige amidobindinger, carboxyl og andre aktive grupper. Amido peptidbinding har biologisk aktivitet og høj kemisk stabilitet, svær at nedbryde ved høj temperatur; carboxylgruppen kan være kompleks med mange metalioner i vand, hvilket gør PASP har høj kemisk aktivitet i vandig opløsning; i hver strukturel enhed af PASP, ilt- og nitrogenatomerne kan nemt danne hydrogenbindinger med vandmolekyler, det har god hydrofilicitet og vandopløselighed. Den særlige molekylære struktur af PASPsikrer, at den har god spredningsevne, korrosionshæmmende egenskaber, fremragende biologisk nedbrydelighed og miljøvenlige egenskaber.

Specifikation:

Anvendelse:

Ifølge forskellige molekylvægte af PASP kan det bruges i vandbehandling, landbrug og skovbrug, olieudvinding, rengøringsmidler og andre områder.

I. Vandbehandling

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, Sag₄, BaSO₄,Ca3(PO₄)₂ ,etc..

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. Landbrug og Skovbrug

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. Udvinding af olie

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. Det har god modstandsdygtighed over for salt og calcium;

IV. Rengøringsmidler

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. Det kan adsorberes på overfladen af ​​porcelæn, forhindre muggen, hvilket resulterer i en bedre rengøringseffekt. Det er en vigtig komponent i opvaskemiddel til rengøring af hårde overflader;

V. Andre applikationer

På grund af dens gode spredning til uorganiske og organiske forbindelser, 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.

Pakke og opbevaring:

200L plasttromle, IBC(1000L), kundernes krav. Opbevaring i ti måneder i skyggefulde rum og tørt sted.

Sikkerhedsbeskyttelse:

PASP er alkalisk, vær opmærksom på arbejdsbeskyttelse ved drift, undgå kontakt med hud, øjne osv., skyl med rigeligt vand efter kontakt.
