Sodium Salt of Polyaspartic Acid (PASP)

Pambuka rinci 

 

Nomer CAS 181828-06-8,35608-40-6 Bobot molekul: 1000-5000

Formula Molekul: C₄H₅NO₃M (C₄H₄NO₃M)m (C₄H₄NO₃M) nC₄H₄NO₃M₂         

Formula Struktural:

Properti:

PASP minangka jinis bahan biopolimer, sing molekul ngemot ikatan amido, karboksil lan gugus aktif liyane. Ikatan peptida Amido nduweni aktivitas biologis lan stabilitas kimia dhuwur, hard kanggo decompose ing suhu dhuwur; gugus karboksil bisa dadi kompleks karo akeh ion logam ing banyu, sing nggawe PASP duwe aktivitas kimia dhuwur ing larutan banyu; ing saben unit struktural saka PASP, atom oksigen lan nitrogen bisa gampang mbentuk ikatan hidrogen karo molekul banyu, wis hydrophilicity apik lan kelarutan banyu. Struktur molekul khusus saka PASPmesthekake yen nduweni kemampuan dispersing apik, sifat nyandhet karat, biodegradability banget lan ciri lingkungan loropaken.

Spesifikasi:

Dianggo:

Miturut bobot molekul beda PASP, bisa digunakake ing perawatan banyu, tetanèn lan kehutanan, eksploitasi petroleum, deterjen lan lapangan liyane.

I. Pengolahan banyu

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, Kasus₄, BaSO₄Ca3 (PO₄)₂ , lsp..

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. Pertanian lan Kehutanan

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. Eksploitasi minyak bumi

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. Wis resistance apik kanggo uyah lan kalsium;

IV. Deterjen

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. Bisa adsorbed ing lumahing dinnerware, nyegah mouldy, asil ing efek reresik luwih. Iku komponen penting saka deterjen dishwashing kanggo reresik saka lumahing hard;

V. Aplikasi liyane

Amarga panyebaran sing apik kanggo senyawa anorganik lan organik, 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.

Paket lan panyimpenan:

200L drum plastik, IBC (1000L), syarat pelanggan. Panyimpenan sepuluh sasi ing kamar teduh lan panggonan sing garing.

Proteksi safety:

PASP iku alkalin, mbayar manungsa waé kanggo pangayoman pegawe nalika operasi, supaya kontak karo kulit, mata, etc., mbilas karo kathah banyu sawise kontak.
