Sodium Salt ng Polyaspartic Acid (PASP)

Detalyadong pagpapakilala 

 

CAS No. 181828-06-8，35608-40-6 Molekular na timbang: 1000-5000

Molecular Formula: C₄H₅HINDI₃M(C₄H₄HINDI₃M)m(C₄H₄HINDI₃M)nC₄H₄HINDI₃M₂         

Istruktural na Formula:

Ari-arian:

PASP ay isang uri ng biopolymer na materyales, kung saan ang mga molekula ay naglalaman ng masaganang amido bond, carboxyl at iba pang aktibong grupo. Ang Amido peptide bond ay may biological na aktibidad at mataas na kemikal na katatagan, mahirap mabulok sa mataas na temperatura; carboxyl group ay maaaring kumplikado na may maraming mga metal ions sa tubig, na gumagawa PASP may mataas na aktibidad ng kemikal sa may tubig na solusyon; sa bawat yunit ng istruktura ng PASP, ang mga atomo ng oxygen at nitrogen ay madaling bumuo ng mga bono ng hydrogen na may mga molekula ng tubig, mayroon itong magandang hydrophilicity at solubility sa tubig. Ang espesyal na istruktura ng molekular ng PASPTinitiyak nito na mayroon itong mahusay na kakayahan sa pagpapakalat, mga katangiang pumipigil sa kaagnasan, mahusay na biodegradability at mga katangiang friendly sa kapaligiran.

Pagtutukoy:

Paggamit:

Ayon sa iba't ibang molecular weights ng PASP, maaari itong magamit sa paggamot ng tubig, agrikultura at kagubatan, pagsasamantala sa petrolyo, mga detergent at iba pang larangan.

I. Paggamot ng tubig

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, Kaso₄, BaSO₄,Ca3(PO₄)₂ ,atbp..

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. Agrikultura at Panggugubat

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. Pagsasamantala sa petrolyo

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. Ito ay may mahusay na pagtutol sa asin at kaltsyum;

IV. Mga detergent

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. Maaari itong i-adsorbed sa ibabaw ng kainan, maiwasan ang amag, na nagreresulta sa mas mahusay na epekto sa paglilinis. Ito ay isang mahalagang bahagi ng dishwashing detergent para sa paglilinis ng matitigas na ibabaw;

V. Iba pang mga Aplikasyon

Dahil sa magandang dispersion nito sa inorganic at organic compouds, 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.

Package at Storage:

200L plastic drum, IBC(1000L), kinakailangan ng mga customer. Imbakan ng sampung buwan sa makulimlim na silid at tuyo na lugar.

Proteksyon sa Kaligtasan:

Ang PASP ay alkaline, bigyang-pansin ang proteksyon sa paggawa kapag nagpapatakbo, iwasan ang pagkakadikit sa balat, mata, atbp., Banlawan ng maraming tubig pagkatapos makipag-ugnay.
