Cov qauv qauv:

Khoom:

PASP yog ib hom biopolymer cov ntaub ntawv, ntawm cov molecules muaj ntau amido daim ntawv cog lus, carboxyl thiab lwm yam active pawg. Amido peptide daim ntawv cog lus muaj kev ua haujlwm lom neeg thiab tshuaj lom neeg ruaj khov, nyuaj rau decompose ntawm qhov kub thiab txias; pawg carboxyl tuaj yeem ua haujlwm nrog ntau cov hlau ions hauv dej, uas ua rau PASP muaj tshuaj lom neeg ua haujlwm siab hauv cov tshuaj aqueous; nyob rau hauv txhua chav tsev ntawm structural PASP, cov pa oxygen thiab nitrogen atoms tau yooj yim tsim hydrogen bonds nrog dej molecules, nws muaj zoo hydrophilicity thiab dej solubility. Qhov tshwj xeeb molecular qauv ntawm PASPxyuas kom meej tias nws muaj peev xwm dispersing zoo, corrosion inhibiting zog, zoo biodegradability thiab ib puag ncig tus phooj ywg yam ntxwv.

Specification:

Kev siv:

Raws li qhov sib txawv molecular hnyav ntawm PASP, nws tuaj yeem siv rau hauv kev kho dej, kev ua liaj ua teb thiab hav zoov, kev siv roj av, tshuaj ntxuav tes thiab lwm yam haujlwm.

I. Kev kho dej

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, Case₄, BAS₄, Ca3(PO₄)₂ ,lwm..

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. Ua liaj ua teb thiab Forestry

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. Petroleum exploitation

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. Nws muaj kev tiv thaiv zoo rau ntsev thiab calcium;

IV. Cov tshuaj ntxuav tes

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. Nws tuaj yeem raug adsorbed rau saum npoo ntawm cov khoom noj khoom haus, tiv thaiv pwm, ua rau muaj kev tu zoo dua. Nws yog ib qho tseem ceeb ntawm cov tshuaj ntxuav tais diav rau kev ntxuav cov tawv tawv;

V. Lwm daim ntawv thov

Vim nws zoo dispersion rau inorganic thiab 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.

Pob thiab Cia:

200L yas nruas, IBC (1000L), cov neeg siv khoom xav tau. Cia rau kaum lub hlis nyob rau hauv shady chav thiab qhuav qhov chaw.

Kev Tiv Thaiv Kev Nyab Xeeb:

PASP yog alkaline, xyuam xim rau kev tiv thaiv kev ua haujlwm thaum ua haujlwm, tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab lwm yam., yaug nrog dej kom ntau tom qab sib cuag.
