Garam Natrium Asid Poliaspartik (PASP)

Pengenalan terperinci 

 

Nombor CAS 181828-06-8，35608-40-6 Berat molekul: 1000-5000

Formula Molekul: C₄H₅TIDAK₃M(C₄H₄TIDAK₃M)m(C₄H₄TIDAK₃M)nC₄H₄TIDAK₃M₂         

Formula Struktur:

sifat:

PASP ialah sejenis bahan biopolimer, di mana molekulnya mengandungi ikatan amido, karboksil dan kumpulan aktif lain yang banyak. Ikatan peptida Amido mempunyai aktiviti biologi dan kestabilan kimia yang tinggi, sukar untuk terurai pada suhu tinggi; kumpulan karboksil boleh menjadi kompleks dengan banyak ion logam dalam air, yang menjadikan PASP mempunyai aktiviti kimia yang tinggi dalam larutan akueus; dalam setiap unit struktur PASP, atom oksigen dan nitrogen dengan mudah boleh membentuk ikatan hidrogen dengan molekul air, ia mempunyai hidrofilik yang baik dan keterlarutan air. Struktur molekul khas bagi PASPmemastikan bahawa ia mempunyai keupayaan penyebaran yang baik, sifat menghalang kakisan, kebolehbiodegradan yang sangat baik dan ciri mesra alam.

Spesifikasi:

penggunaan:

Mengikut berat molekul PASP yang berbeza, ia boleh digunakan dalam rawatan air, pertanian dan perhutanan, eksploitasi petroleum, detergen dan bidang lain.

I. Rawatan air

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, Kes₄, BaSO₄,Ca3(PO₄)₂ ,dan lain-lain..

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 dan Perhutanan

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 petroleum

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. Ia mempunyai ketahanan yang baik terhadap garam dan kalsium;

IV. Bahan pencuci

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. Ia boleh diserap pada permukaan peralatan makan, mengelakkan berkulat, menghasilkan kesan pembersihan yang lebih baik. Ia adalah komponen penting dalam detergen pencuci pinggan untuk membersihkan permukaan keras;

V. Aplikasi Lain

Kerana penyebarannya yang baik kepada kompaun tak organik dan 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.

Pakej dan Penyimpanan:

Drum plastik 200L, IBC(1000L), keperluan pelanggan. Penyimpanan selama sepuluh bulan di dalam bilik teduh dan tempat kering.

Perlindungan Keselamatan:

PASP adalah beralkali, beri perhatian kepada perlindungan buruh semasa beroperasi, elakkan terkena kulit, mata, dsb., bilas dengan banyak air selepas bersentuhan.
