Natrijumova so poliasparaginske kiseline (PASP)

Detaljan uvod 

 

CAS br. 181828-06-8, 35608-40-6 Molekularna težina: 1000-5000

Molekularna formula: C₄H₅NO₃M(C₄H₄NO₃M)m(C₄H₄NO₃M)nC₄H₄NO₃M₂         

Strukturna formula:

Svojstva:

PASP je vrsta biopolimernih materijala, čiji molekuli sadrže obilje amido veze, karboksilnih i drugih aktivnih grupa. Amido peptidna veza ima biološku aktivnost i visoku hemijsku stabilnost, teško se razgrađuje na visokoj temperaturi; karboksilna grupa može biti kompleksna sa mnogo metalnih jona u vodi, koji čine PASP imaju visoku hemijsku aktivnost u vodenom rastvoru; u svakoj strukturnoj jedinici PASP, atomi kisika i dušika mogu lako formirati vodikove veze s molekulima vode, ima dobru hidrofilnost i topljivost u vodi. Posebna molekularna struktura PASPosigurava da ima dobru sposobnost dispergiranja, svojstva inhibiranja korozije, odličnu biorazgradljivost i ekološke karakteristike.

Upotreba:

Prema različitim molekularnim masama PASP, može se koristiti u tretmanu vode, poljoprivredi i šumarstvu, eksploataciji nafte, deterdžentima i drugim poljima.

I. Tretman vode

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, Case₄, BaSO₄,Ca3(PO₄)₂ itd..

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. Poljoprivreda i šumarstvo

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. Eksploatacija nafte

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. Ima dobru otpornost na sol i kalcij;

IV. Deterdženti

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. Može se adsorbirati na površini posuđa, spriječiti buđ, što rezultira boljim efektom čišćenja. Važna je komponenta deterdženta za pranje sudova za čišćenje tvrdih površina;

V. Ostale primjene

Zbog svoje dobre disperzije na anorganska i organska jedinjenja, 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.

Pakovanje i skladištenje:

200L plastična bačva, IBC(1000L), zahtjev kupaca. Skladištenje deset mjeseci u sjenovitom i suhom mjestu.

Sigurnosna zaštita:

PASP je alkalan, pri radu obratite pažnju na zaštitu rada, izbegavajte kontakt sa kožom, očima i sl., nakon kontakta isperite sa dosta vode.
