Inombolo ye-CAS 181828-06-8,35608-40-6 Isisindo se-Molecular: 1000-5000

I-Molecular Formula: C₄H₅CHA₃M(C₄H₄CHA₃M)m(C₄H₄CHA₃M)nC₄H₄CHA₃M₂         

Ifomula Yesakhiwo:

Izakhiwo:

I-PASP iwuhlobo lwezinto ze-biopolymer, lapho ama-molecule aqukethe i-amido bond eningi, i-carboxyl namanye amaqembu asebenzayo. Isibopho se-Amido peptide sinomsebenzi wezinto eziphilayo kanye nokuzinza kwamakhemikhali aphezulu, okunzima ukubola ekushiseni okuphezulu; iqembu le-carboxyl lingaba yinkimbinkimbi nama-ion amaningi ensimbi emanzini, okwenza I-PASP ube nomsebenzi wamakhemikhali aphezulu kwisisombululo esinamanzi; kuyunithi ngayinye yesakhiwo I-PASP, ama-athomu omoya-mpilo ne-nitrogen angakha kalula izibopho ze-hydrogen nama-molecule wamanzi, ane-hydrophilicity enhle kanye nokuncibilika kwamanzi. Isakhiwo samangqamuzana esikhethekile se I-PASPiqinisekisa ukuthi inekhono elihle lokuhlakaza, izakhiwo ezivimbela ukugqwala, ukubola okuhle kakhulu kwe-biodegradability kanye nezici ezivumelana nemvelo.

Ukucaciswa:

Ukusetshenziswa:

Ngokwezisindo ezihlukene zamangqamuzana e-PASP, ingasetshenziswa ekuhlanzeni amanzi, ezolimo namahlathi, ukuxhashazwa kwe-petroleum, okokuhlanza neminye imikhakha.

I. Ukwelashwa kwamanzi

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, Icala₄, BASO₄,Ca3(PO₄)₂ njll..

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. Ukuxhashazwa kwe-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. Inokumelana okuhle nosawoti kanye ne-calcium;

IV. Izihlanzi

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. Ingakhangiswa ebusweni be-dinnerware, ivimbele ukukhunta, okuholela kumphumela ongcono wokuhlanza. Kuyingxenye ebalulekile yomshini wokuwasha izitsha wokuhlanza izindawo eziqinile;

V. Ezinye izinhlelo zokusebenza

Ngenxa yokuhlakazeka kwayo okuhle kuma-inorganic and 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.

Iphakheji Nesitoreji:

200L plastic sigubhu, IBC(1000L), imfuneko amakhasimende. Isitoreji izinyanga eziyishumi ekamelweni elinomthunzi nasendaweni eyomile.

Ukuvikela Ukuphepha:

I-PASP ine-alkaline, qaphela ukuvikelwa kwabasebenzi lapho usebenza, gwema ukuthintana nesikhumba, amehlo, njll., hlambulula ngamanzi amaningi ngemva kokuxhumana.
