Fformiwla Strwythurol:

Priodweddau:

PASP yn fath o ddeunyddiau biopolymer, y mae moleciwlau ohonynt yn cynnwys bond amido helaeth, carboxyl a grwpiau gweithredol eraill. Mae gan fond peptid Amido weithgaredd biolegol a sefydlogrwydd cemegol uchel, sy'n anodd ei ddadelfennu ar dymheredd uchel; Gall grŵp carboxyl fod yn gymhleth gyda llawer o ïonau metel mewn dŵr, sy'n gwneud PASP â gweithgaredd cemegol uchel mewn hydoddiant dyfrllyd; ym mhob uned strwythurol o PASP, gall yr atomau ocsigen a nitrogen ffurfio bondiau hydrogen yn hawdd â moleciwlau dŵr, mae ganddo hydrophilicity da a hydoddedd dŵr. Mae strwythur moleciwlaidd arbennig o PASPyn sicrhau bod ganddo allu gwasgaru da, priodweddau atal cyrydiad, bioddiraddadwyedd rhagorol a nodweddion sy'n gyfeillgar i'r amgylchedd.

Defnydd:

Yn ôl gwahanol bwysau moleciwlaidd PASP, gellir ei ddefnyddio mewn trin dŵr, amaethyddiaeth a choedwigaeth, ecsbloetio petrolewm, glanedyddion a meysydd eraill.

I. Triniaeth dwfr

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, Achos₄, BaSO₄, Ca3(PO₄)₂ , ac ati..

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. Amaethyddiaeth a Choedwigaeth

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. Ecsbloetio petrolewm

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. Mae ganddo wrthwynebiad da i halen a chalsiwm;

IV. Glanedyddion

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. Gellir ei adsorbed ar wyneb llestri cinio, atal llwydni, gan arwain at well effaith glanhau. Mae'n elfen bwysig o lanedydd golchi llestri ar gyfer glanhau arwynebau caled;

V. Cymwysiadau Eraill

Oherwydd ei wasgariad da i gyfansoddion anorganig ac organig, 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.

Diogelu diogelwch:

Mae PASP yn alcalïaidd, rhowch sylw i amddiffyniad llafur wrth weithredu, osgoi cysylltiad â chroen, llygaid, ac ati, rinsiwch â digon o ddŵr ar ôl dod i gysylltiad.
