Polyethylenimine(PEI)o se polymer solu vai. O le faʻatonuga i le vai o oloa faʻapisinisi e masani lava 20% i le 50%. PEI e polymerized mai ethylene imide monomer. Ose polymer cationic e masani ona foliga mai o se vai e le lanu samasama po'o le malo ma le tele o le mamafa mole mole ma fesuiaiga o le fausaga.

O le apolyethyleneiminegaluega faatino?

1. Adhesion maualuga, maualuga absorption amino vaega e mafai ona tali atu i le vaega hydroxyl e fausia ai le hydrogen sootaga, vaega amine e mafai ona tali atu i le vaega carboxyl e fausia ai sootaga ionic, vaega amine e mafai foi ona tali atu i le vaega carbon acyl e fausia sootaga covalent. I le taimi lava e tasi, ona o lona vaega polar (amine) ma le hydrophobic group (vinyl) fausaga, e mafai ona tuʻufaʻatasia ma mea eseese. Faatasi ai ma nei malosiaga faʻapipiʻi atoatoa, e mafai ona faʻaaogaina lautele i fanua o faʻamaufaʻailoga, vaitusi, vali, fusi ma isi.

2. High-cationic polyvinyl imide o loʻo i ai i le tulaga o le polycation i le vai, lea e mafai ona faʻaumatia ma faʻafefe uma mea anionic. E chelates foi ion uamea mamafa. Faʻatasi ai ma ona tulaga maualuga cationic, e mafai ona faʻaaogaina i le faia o pepa, togafitiga vai, fofo faʻapipiʻi, dispersant ma isi fanua.

3. O le polyethylenimine maualuga fa'aalia ona o le amine muamua ma le lua, o lea e faigofie ai ona tali atu i le epoxy, acids, isocyanate compounds ma gas acid. I le faʻaaogaina o lenei mea totino, e mafai ona faʻaaogaina e avea o se epoxy reactant, o se aldehyde adsorbent ma se mea faʻapipiʻi lanu.

O le a le mea e faʻaaogaina ai le polyethylenimine?

Polyethylenimine (PEI)ose fa'aputuga polymer felavasa'i ma fa'aoga eseese, e aofia ai ae le fa'atapula'aina i:

1. Suavai ma alamanuia pepa. I le avea ai o se sui malosi susu, e faʻaaogaina i pepa faʻafefete faʻafefeteina (e pei o le pepa faamama, pepa vaitusi, pepa faleuila, ma isi), lea e mafai ona faʻaleleia le malosi susu o pepa ma faʻaitiitia le faʻaleagaina o le gaosiga o pepa, aʻo faʻavaveina le fa'amama vai o le alavaa ma fa'afaigofie ona fa'afefete alava lelei.

2. Su'e fa'apipi'i lanu. E i ai se malosi fa'amaufa'ailoga mo vaila'au oona ma e mafai ona fa'aoga e fai ma sui fa'amau pe a vali pepa fa'alanu vai.

3. Suiga alava ma vali vali fesoasoani. Mo togafitiga fiber, e pei o le ofutau o le tino, totigilima anti-oti, maea, ma isi.

4. Mea faaeletonika. I le fanua o mea tau eletise, polyethylene imide ata tifaga e mafai ona faʻaaogaina e avea o se faʻavae tuʻufua, mea faʻapipiʻi ma ufiufi vaega o mea faʻaeletoroni, ma isi, faʻatasi ai ma le faʻaogaina lelei ma le maualuga o le vevela.

5. afifiina meaai. I le avea ai o se mea e teu ai meaʻai, o loʻo i ai le lelei o le susu-faʻamaonia, lelei le kesi teteʻe, le oona, tofo, maualuga vevela tetee, ma isi, ma e masani ona faʻaaogaina i le afifiina o aano o manufasi, moa, fualaau aina, fualaau faisua, kofe ma. isi oloa.

6. Mea fa'afoma'i. Polyvinylimine e mafai ona faʻaaogaina i masini faʻafomaʻi, meafaigaluega faʻapitoa, afifiina faafomaʻi, ma isi, e pei o laei faʻafomaʻi ma ata tifaga manino.

7. Fa'apipi'i. I le avea ai o se mea faʻapipiʻi maualuga, e faʻaaogaina i le gaosiga o le aerospace, mea faʻaeletoroni, vaega taʻavale ma isi.

8. Suavai faʻamaʻi ma faʻasalalau. E faʻaaogaina lautele i le faʻaaogaina o pepa vai, fofo eletise, dispersant ma isi fanua. E feavea'i kenera. O le Polyvinylimide o se ve'a e le-viral mo le tu'uina atu o ga'o, aemaise lava mo le felauaiga fa'atasi o le tele o plasmids.

I le male,polyethylenimineei ai foi uiga o le adhesion maualuga, adsorption maualuga, cation maualuga, maualuga reactivity, ma isi, ma e faʻaaogaina lautele i fanua o vali, vaitusi, pipii, togafitiga fiber, togafitiga otaota ma isi.

I se tulaga lautele, o le polyvinylimide o se polymer faʻapitoa ma le tele o faʻaoga, ma o ona meatotino e mafai ona fetuunai ma faʻaleleia e ala i le suia o le mamafa o le mole, fausaga ma le faʻatinoga.
