Natrium sâlt fan polyasparaginezuur (PASP)

Detaillearre ynlieding 

 

CAS No. 181828-06-8，35608-40-6 Molekulêre gewicht: 1000-5000

Molekulêre formule: C₄H₅NEE₃M(C₄H₄NEE₃M)m(C₄H₄NEE₃M)nC₄H₄NEE₃M₂         

Strukturele formule:

Eigenskippen:

PASP is in soarte fan biopolymer materialen, wêrfan molekulen befettet oerfloedich amido bân, carboxyl en oare aktive groepen. Amido peptide bân hat biologyske aktiviteit en hege gemyske stabiliteit, dreech te ûntbinen by hege temperatuer; karboksylgroep kin kompleks wêze mei in protte metaalionen yn wetter, dy't meitsje PASP hawwe hege gemyske aktiviteit yn wetterige oplossing; yn elke strukturele ienheid fan PASP, de soerstof en stikstof atomen kinne maklik foarmje wetterstof obligaasjes mei wetter molekulen, it hat goede hydrophilicity en wetter oplosberens. De spesjale molekulêre struktuer fan PASPsoarget derfoar dat it hat goede dispersing fermogen, corrosie inhibiting eigenskippen, poerbêst biologyske ôfbrekberens en miljeufreonlike skaaimerken.

Spesifikaasje:

Gebrûk:

Neffens ferskate molekulêre gewichten fan PASP, kin it brûkt wurde yn wettersuvering, lânbou en boskbou, petroleum eksploitaasje, detergenten en oare fjilden.

I. Wetter behanneling

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, Rjochtsaak₄, BaSO₄,Ca3(PO₄)₂ , ensfh.

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. Lânbou en Boskbou

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 eksploitaasje

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. It hat goede ferset tsjin sâlt en kalzium;

IV. Detergenten

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. It kin wurde adsorbearre op it oerflak fan servies, foarkommen fan skimmel, wat resulteart yn in bettere reinigingseffekt. It is in wichtich ûnderdiel fan ôfwaskmiddel foar skjinmeitsjen fan hurde oerflakken;

V. Oare applikaasjes

Fanwegen syn goede dispersion nei anorganyske en organyske ferbiningen, 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.

Pakket en opslach:

200L plastic trommel, IBC (1000L), klanten 'eask. Opslach foar tsien moannen yn skaadlike keamer en droech plak.

Feiligens beskerming:

PASP is alkaline, betelje omtinken foar arbeid beskerming by it operearjen, foarkom kontakt mei hûd, eagen, ensfh., spoel mei in soad wetter nei kontakt.
