Natriumsalt av polyasparaginsyre (PASP)

Detaljert introduksjon 

 

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

Molekylformel: C₄H₅NEI₃M(C₄H₄NEI₃M)m(C₄H₄NEI₃M)nC₄H₄NEI₃M₂         

Strukturformel:

Egenskaper:

PASP er en slags biopolymermaterialer, hvorav molekylene inneholder rikelig amidobinding, karboksyl og andre aktive grupper. Amido peptidbinding har biologisk aktivitet og høy kjemisk stabilitet, vanskelig å dekomponere ved høy temperatur; karboksylgruppen kan være kompleks med mange metallioner i vann, som gjør PASP har høy kjemisk aktivitet i vandig løsning; i hver strukturell enhet av PASP, oksygen- og nitrogenatomene kan lett danne hydrogenbindinger med vannmolekyler, det har god hydrofilisitet og vannløselighet. Den spesielle molekylære strukturen til PASPsikrer at den har god spredningsevne, korrosjonshemmende egenskaper, utmerket biologisk nedbrytbarhet og miljøvennlige egenskaper.

Spesifikasjon:

Bruk:

I henhold til forskjellige molekylvekter til PASP kan den brukes i vannbehandling, landbruk og skogbruk, petroleumsutvinning, vaskemidler og andre felt.

I. Vannbehandling

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, Sak₄, 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. Jordbruk og skogbruk

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. Petroleumsutvinning

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. Den har god motstand mot salt og kalsium;

IV. Vaskemidler

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 overflaten av servise, forhindre muggen, noe som resulterer i bedre renseeffekt. Det er en viktig komponent i oppvaskmiddel for rengjøring av harde overflater;

V. Andre applikasjoner

På grunn av sin 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 oppbevaring:

200L plasttrommel, IBC(1000L), kundenes krav. Oppbevaring i ti måneder i skyggefulle rom og tørt sted.

Sikkerhetsbeskyttelse:

PASP er alkalisk, vær oppmerksom på arbeidsbeskyttelse ved bruk, unngå kontakt med hud, øyne osv., skyll med mye vann etter kontakt.
