Eiginleikar:

PASP er eins konar líffjölliða efni, þar sem sameindir innihalda mikið amíótengi, karboxýl og aðra virka hópa. Amido peptíðtengi hefur líffræðilega virkni og mikinn efnafræðilegan stöðugleika, erfitt að brjóta niður við háan hita; karboxýlhópur getur verið flókinn með mörgum málmjónum í vatni, sem mynda PASP hafa mikla efnavirkni í vatnslausn; í hverri byggingareiningu af PASP, súrefnis- og köfnunarefnisatómin geta auðveldlega myndað vetnistengi með vatnssameindum, það hefur góða vatnssækni og vatnsleysni. Hin sérstaka sameindabyggingu PASPtryggir að það hafi góða dreifingargetu, tæringarhemjandi eiginleika, framúrskarandi lífbrjótanleika og umhverfisvæna eiginleika.

Tæknilýsing:

Notkun:

Samkvæmt mismunandi mólþunga PASP er hægt að nota það í vatnsmeðferð, landbúnaði og skógrækt, jarðolíunýtingu, hreinsiefni og öðrum sviðum.

I. Vatnsmeðferð

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, Málið₄, BaSO₄,Ca3(PO₄)₂ , o.s.frv..

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. Landbúnaður og skógrækt

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. Olíunýting

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. Það hefur góða viðnám gegn salti og kalsíum;

IV. Þvottaefni

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. Það er hægt að aðsogast á yfirborð borðbúnaðarins, koma í veg fyrir myglu, sem leiðir til betri hreinsunaráhrifa. Það er mikilvægur hluti af uppþvottaefni til að þrífa hörð yfirborð;

V. Önnur forrit

Vegna góðrar dreifingar í ólífræn og lífræn efnasambönd, 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.

Pakki og geymsla:

200L plasttromma, IBC(1000L), kröfur viðskiptavina. Geymsla í tíu mánuði í skuggalegu herbergi og þurrum stað.

Öryggisvörn:

PASP er basískt, gaum að vinnuvernd við notkun, forðastu snertingu við húð, augu o.s.frv., skolaðu með miklu vatni eftir snertingu.
