Ityuwa yeSodium yePolyaspartic Acid (PASP)

Intshayelelo eneenkcukacha 

 

Inombolo yeCAS

Ifomula yemolekyuli: C₄H₅HAYI₃M(C₄H₄HAYI₃M)m(C₄H₄HAYI₃M)nC₄H₄HAYI₃M₂         

Ifomula yoLwakhiwo:

Iinkcazelo ngeempawu:

PASP luhlobo lwezixhobo ze-biopolymer, apho iimolekyuli ziqulethe i-amido bond eninzi, i-carboxyl kunye namanye amaqela asebenzayo. I-Amido peptide bond inomsebenzi we-biological kunye nokuzinza kweekhemikhali eziphezulu, kunzima ukubola kwiqondo lokushisa eliphezulu; Iqela le-carboxyl linokuba nzima kunye neeyoni ezininzi zetsimbi emanzini, ezenza PASP ube nomsebenzi ophezulu weekhemikhali kwisisombululo samanzi; kwiyunithi nganye yolwakhiwo lwe PASP, i-oksijini kunye ne-athomu ye-nitrogen inokwenza lula iibhondi ze-hydrogen kunye neemolekyuli zamanzi, ine-hydrophilicity enhle kunye nokunyibilika kwamanzi. Ubume obukhethekileyo bemolekyuli ye PASPiqinisekisa ukuba inamandla okusasaza alungileyo, iipropathi ezithintela ukubola, ukubola kwebhayoloji okugqwesileyo kunye neempawu ezihambelana nokusingqongileyo.

Inkcazo:

Ukusetyenziswa:

Ngokutsho kobunzima beemolekyuli ezahlukeneyo zePASP, ingasetyenziswa kunyango lwamanzi, ezolimo kunye namahlathi, ukusetyenziswa kwepetroleum, iidetergents kunye nezinye iindawo.

I. Unyango lwamanzi

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, Ityala₄, BASO₄,Ca3(PO₄)₂ njl..

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. EzoLimo naMahlathi

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. Ukusetyenziswa kwepetroleum

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. Inokumelana kakuhle netyuwa kunye ne-calcium;

IV. Izicoci

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. Inokuthi ibhengezwe kumphezulu we-dinnerware, ithintele ukubunjwa, okukhokelela kwisiphumo esingcono sokucoca. Iyinxalenye ebalulekileyo ye-detergent yokucoca i-detergent yokucoca iindawo ezinzima;

V. Ezinye izicelo

Ngenxa yokusasazwa kwayo kakuhle kwi-inorganic kunye ne-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.

Ukupakishwa kunye noGcino:

200L igubu zeplastiki, IBC (1000L), imfuno abathengi '. Ukugcinwa kweenyanga ezilishumi kwigumbi elinomthunzi kunye nendawo eyomileyo.

Ukhuseleko loKhuseleko:

I-PASP i-alkaline, nikela ingqalelo ekukhuselweni kwabasebenzi xa usebenza, ugweme ukudibanisa nesikhumba, amehlo, njl., Sula ngamanzi amaninzi emva kokudibana.
