danasîna berfireh 

 

CAS No.  181828-06-8，35608-40-6                 Molecular weight:  1000-5000

Molecular Formula:   C₄H₅NA₃M(C₄H₄NA₃M)m(C₄H₄NA₃M)nC₄H₄NA₃M₂         

Formula Structural:

Taybetmendî:

PASP celebek materyalên biopolîmer e, ku molekulên wan tê de girêdana amido, karboksîl û komên din ên çalak hene. Girêdana amido peptide xwedan çalakiya biyolojîkî û aramiya kîmyewî ya bilind e, ku di germahiya bilind de dijwar tê hilweşandin; koma karboksîl dikare bi gelek îyonên metal ên di avê de tevlihev be, ku çêdikin PASP di çareseriya avî de çalakiya kîmyewî ya bilind heye; di her yekîneyek avahî ya PASP, atomên oksîjen û nîtrojenê bi molekulên avê re bi hêsanî girêdanên hîdrojenê çêdikin, hîdrofîlîbûn û çareserbûna avê ya baş heye. Avahiya molekulê ya taybetî ya PASPpiştrast dike ku ew xwedan şiyana belavkirinê ya baş, taybetmendiyên astengkirina korozyonê, biyolojîkîbûna hêja û taybetmendiyên dostaniya jîngehê ye.

Specification:

Bikaranîn:

Li gorî giraniyên molekular ên cihêreng ên PASP, ew dikare di dermankirina avê, çandinî û daristanî, karanîna neftê, paqijker û zeviyên din de were bikar anîn.

I. Tedawiya avê

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 , hwd..

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. Çandinî û Daristanî

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. Karanîna petrolê

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. Li hember xwê û kalsiyûmê berxwedanek baş heye;

IV. Detergents

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. Ew dikare li ser rûyê şîvê were rijandin, pêşî li kelijandinê bigire, di encamê de bandora paqijkirina çêtir çêdibe. Ew hêmanek girîng a paqijkirina firaqê ye ji bo paqijkirina rûyên hişk;

V. Serlêdanên din

Ji ber belavbûna wê ya baş li pêkhateyên înorganîk û organîk, 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.

Pakêt û hilanîn:

200L drumek plastîk, IBC (1000L), hewcedariya xerîdaran. Deh mehan li jûreyek siya û cîhê zuwa hilînin.

Parastina Ewlekariyê:

PASP alkalîn e, dema xebitandinê bala xwe bidin parastina kedê, ji têkiliya bi çerm, çav û hwd re dûr bixin, piştî têkiliyê bi pir avê bişon.
