Garam Natrium Asam Poliaspartat (PASP)

Pengenalan rinci 

 

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

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

Formula struktural:

Properti:

PASP adalah sejenis bahan biopolimer, yang molekulnya banyak mengandung ikatan tengah, karboksil, dan gugus aktif lainnya. Ikatan peptida Amido memiliki aktivitas biologis dan stabilitas kimia yang tinggi, sulit terurai pada suhu tinggi; gugus karboksil dapat menjadi kompleks dengan banyak ion logam dalam air, yang menghasilkan PASP memiliki aktivitas kimia yang tinggi dalam larutan air; di setiap unit struktural PASP, atom oksigen dan nitrogen dapat dengan mudah membentuk ikatan hidrogen dengan molekul air, memiliki hidrofilisitas dan kelarutan air yang baik. Struktur molekul khusus dari PASPmemastikan bahwa ia memiliki kemampuan pendispersi yang baik, sifat penghambat korosi, kemampuan terurai secara hayati yang sangat baik dan karakteristik ramah lingkungan.

Spesifikasi:

Penggunaan:

Menurut berat molekul PASP yang berbeda, PASP dapat digunakan dalam pengolahan air, pertanian dan kehutanan, eksploitasi minyak bumi, deterjen dan bidang lainnya.

I.Pengolahan 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, Kasus₄, BaSO₄,Ca3(PO₄)₂ ,dll..

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 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.

AKU AKU AKU. 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. Ia memiliki ketahanan yang baik terhadap garam dan 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. Dapat terserap pada permukaan peralatan makan, mencegah jamur, sehingga menghasilkan efek pembersihan yang lebih baik. Ini merupakan komponen penting dari deterjen pencuci piring untuk membersihkan permukaan keras;

V.Aplikasi Lainnya

Karena dispersinya yang baik terhadap senyawa anorganik 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.

Paket dan Penyimpanan:

Drum plastik 200L, IBC(1000L), kebutuhan pelanggan. Penyimpanan selama sepuluh bulan di ruangan teduh dan kering.

Perlindungan Keamanan:

PASP bersifat basa, perhatikan perlindungan tenaga kerja saat beroperasi, hindari kontak dengan kulit, mata, dll., Bilas dengan banyak air setelah kontak.
