Chiyambi chatsatanetsatane 

 

CAS No. 181828-06-8,35608-40-6 Molecular kulemera: 1000-5000

Molecular formula: C₄H₅AYI₃M (C₄H₄AYI₃M)m(C₄H₄AYI₃M) nC₄H₄AYI₃M₂         

Ndondomeko Yopanga:

Katundu:

PASP ndi mtundu wa zida za biopolymer, zomwe mamolekyu amakhala ndi zomangira zambiri za amido, carboxyl ndi magulu ena ogwira ntchito. Chomangira cha Amido peptide chimakhala ndi zochitika zachilengedwe komanso kukhazikika kwamankhwala, zovuta kuwola pakutentha kwambiri; gulu la carboxyl limatha kukhala lovuta ndi ayoni ambiri azitsulo m'madzi, omwe amapanga PASP kukhala ndi zochita zambiri za mankhwala mu njira yamadzi; mu gawo lililonse la zomangamanga PASP, ma atomu okosijeni ndi nayitrogeni amatha kupanga zomangira za haidrojeni ndi mamolekyu amadzi, zimakhala ndi hydrophilicity yabwino komanso kusungunuka kwamadzi. Mapangidwe apadera a maselo a PASPimawonetsetsa kuti ili ndi luso lobalalitsa bwino, zolepheretsa dzimbiri, kuwonongeka kwachilengedwe komanso mawonekedwe osagwirizana ndi chilengedwe.

Kagwiritsidwe:

Malinga ndi zolemetsa zosiyanasiyana za PASP, zitha kugwiritsidwa ntchito pochiza madzi, ulimi ndi nkhalango, kugwiritsa ntchito mafuta, zotsukira ndi zina.

I. Mankhwala a madzi

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, Mlandu₄, BASO₄Ca3(PO₄)₂ ndi..

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. Ulimi ndi Zankhalango

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. Kugwiritsidwa ntchito kwa mafuta

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. Ili ndi kukana bwino kwa mchere ndi calcium;

IV. Zotsukira

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. Itha kukhala adsorbed pamwamba pa dinnerware, kupewa nkhungu, zomwe zimapangitsa kuyeretsa bwino. Ndi gawo lofunikira la chotsukira mbale poyeretsa malo olimba;

V. Ntchito Zina

Chifukwa cha kupezeka kwake kwabwino kwa organic compouds ndi organic, 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.

Phukusi ndi Kusunga:

200L pulasitiki ng'oma, IBC (1000L), chofunika makasitomala '. Kusungirako kwa miyezi khumi mu chipinda chamthunzi ndi malo owuma.

Chitetezo cha Chitetezo:

PASP ndi zamchere, tcherani khutu ku chitetezo cha ogwira ntchito pogwira ntchito, pewani kukhudzana ndi khungu, maso, ndi zina zotero, muzimutsuka ndi madzi ambiri mutatha kukhudzana.
