Foirmle Structarail:

Feartan:

PASP Is e seòrsa de stuthan biopolymer a th’ ann, anns a bheil pailteas amido bond, carboxyl agus buidhnean gnìomhach eile ann am moileciuilean. Tha gnìomhachd bith-eòlasach agus seasmhachd ceimigeach àrd aig bann Amido peptide, duilich a lobhadh aig teòthachd àrd; buidheann carboxyl urrainn a bhith iom-fhillte le iomadh meatailt ions ann an uisge, a tha a 'dèanamh PASP le gnìomhachd ceimigeach àrd ann am fuasgladh uisgeach; anns gach aonad structarail de PASP, faodaidh na dadaman ocsaidean agus naitridean gu furasta ceanglaichean hydrogen a chruthachadh le moileciuilean uisge, tha deagh hydrophilicity agus solubility uisge aige. Tha structar sònraichte moileciuil na PASPa’ dèanamh cinnteach gu bheil comas sgaoilidh math aige, feartan bacadh meirg, bith-ruigsinneachd sàr-mhath agus feartan càirdeil don àrainneachd.

Sònrachadh:

Cleachdadh:

A rèir diofar cuideaman moileciuil de PASP, faodar a chleachdadh ann an làimhseachadh uisge, àiteachas agus coilltearachd, cleachdadh petroleum, innealan-glanaidh agus raointean eile.

I. Làimhseachadh uisge

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, Cùis₄, BaSO₄, Ca3(PO₄)₂ , etc..

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. Àiteachas agus Coilltearachd

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. Cleachdadh 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. Tha deagh sheasamh aige an aghaidh salainn agus calcium;

IV. Glanadairean

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. Faodar a shanasachadh air uachdar aodach dìnnear, casg a chuir air mouldy, agus mar thoradh air sin bidh buaidh glanaidh nas fheàrr. Tha e na phàirt chudromach de inneal-glanaidh nigheadaireachd airson glanadh uachdar cruaidh;

V. Iarrtasan Eile

Mar thoradh air an deagh sgapadh gu companaidhean neo-organach agus organach, 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.

Pacadh agus stòradh:

200L plastaig druma, IBC (1000L), luchd-ceannach a 'riatanas. Stòradh airson deich mìosan ann an seòmar dubharach agus àite tioram.

Dìon Sàbhailteachd:

Tha PASP alcaileach, thoir aire do dhìon saothair nuair a bhios tu ag obair, seachain conaltradh le craiceann, sùilean, msaa, nigh le uisge gu leòr às deidh conaltradh.
