Polyethylenimine(PEI)yipolima enyibilikayo emanzini. Ukugxininiswa kwamanzi kwiimveliso zorhwebo ngokuqhelekileyo yi-20% ukuya kwi-50%. I-PEI yenziwe i-polymerized ukusuka kwi-ethylene imide monomer. Yipolymer ye-cationic edla ngokubonakala njengolwelo olungenambala ukuya kumthubi okanye oluqinileyo olunobunzima obahlukeneyo bemolekyuli kunye nokwahluka kolwakhiwo.

Yintoni ii-polyethyleneimineumsebenzi?

1. I-adhesion ephezulu, i-amino ephezulu yokufunxa inokusabela kunye neqela le-hydroxyl ukwenza i-hydrogen bond, iqela le-amine linokusabela kunye neqela le-carboxyl ukwenza i-ionic bond, iqela le-amine linokusabela kunye neqela le-carbon acyl ukwenza i-covalent bond. Ngelo xesha, ngenxa yeqela layo le-polar (i-amine) kunye neqela le-hydrophobic (vinyl) isakhiwo, sinokudibaniswa nezinto ezahlukeneyo. Ngala mandla abophezelayo abanzi, anokusetyenziswa ngokubanzi kwiindawo zokutywinwa, i-inki, ipeyinti, i-binder njalo njalo.

2. I-high-cationic polyvinyl imide ikhona ngendlela yepolycation emanzini, enokuthi i-neutralize kwaye ibhengeze zonke izinto ze-anionic. Ikwatshisa iiyoni zentsimbi enzima. Ngeempawu zayo eziphezulu ze-cationic, ingasetyenziselwa ukwenza iphepha, unyango lwamanzi, isisombululo se-plating, i-dispersant kunye nezinye iindawo.

3. I-polyethylenimine esebenzayo kakhulu ngenxa ye-amines esebenzayo kakhulu kunye neyesibini, ngoko inokusabela ngokulula nge-epoxy, i-acids, i-isocyanate compounds kunye neegesi ze-asidi. Ukusebenzisa le propati, ingasetyenziselwa njenge-epoxy reactant, i-aldehyde adsorbent kunye ne-agent yokulungisa umbala.

Isetyenziselwa ntoni i-polyethylenimine?

Polyethylenimine (PEI)yikhompawundi yepolymer enemisebenzi eyahlukeneyo, ebandakanya kodwa ingaphelelanga apho:

1. Ukucocwa kwamanzi kunye noshishino lwephepha. Njengearhente yamandla emanzi, isetyenziswa kwiphepha lokufunxa i-ngummed (elifana nephepha lokucoca, iphepha lokuvala i-inki, iphepha lendlu yangasese, njl.njl.), elinokuphucula amandla amanzi ephepha kunye nokunciphisa umonakalo wokucutshungulwa kwephepha, ngelixa kukhawulezisa ukuhluzwa kwamanzi kwi-pulp kunye nokwenza imicu ecolekileyo ukudada lula.

2. I-arhente yokulungisa umbala. Inamandla okubophelela okuqinileyo kwidayi ye-asidi kwaye inokusetyenziswa njenge-arhente yokulungisa xa idayi ye-asidi idayi iphepha.

3. Ukuguqulwa kweFayibha kunye nokudaya abancedisi. Kunyango lwefayibha, njengezixhobo zomzimba, iiglavu ezichasene nokusika, intambo, njl.

4. Izinto zombane. Kwintsimi ye-electronics, ifilimu ye-polyethylene imide ingasetyenziselwa njengoluhlu oluzimeleyo, izinto ezikhuselayo kunye ne-covering layer yamacandelo e-elektroniki, njl., kunye nokusebenza kakuhle kwe-insulation kunye nokumelana nokushisa okuphezulu.

5. Ukupakishwa kokutya. Njengempahla yokupakisha ukutya, ineenzuzo zobungqina bokufuma, ukuxhathisa igesi kakuhle, i-non-toxic, i-tasteless, ukumelana nobushushu obuphezulu, njl., kwaye isetyenziswa ngokubanzi kwi-package yenyama, iinkukhu, iziqhamo, imifuno, ikofu kunye nezinye iimveliso.

6. Izinto zonyango. I-Polyvinylimine ingasetyenziselwa izixhobo zonyango, izixhobo zokuxilonga, ukupakishwa kwezonyango, njl., ezifana neengubo zonyango kunye neefilimu ezicacileyo zonyango.

7. Ukuncamathelisa. Njengokunamathelisa okuphezulu, isetyenziselwa ukwenziwa kwe-aerospace, izixhobo ze-elektroniki, iinxalenye zeemoto kunye nokunye.

8. Iiarhente zokunyanga amanzi kunye nezisasazo. Isetyenziswa ngokubanzi kunyango lwamanzi lokwenza iphepha, isisombululo se-electroplating, i-dispersant kunye nezinye iindawo. Umthwali wemfuza. I-Polyvinylimide yi-vector engeyiyo i-viral yokuhanjiswa kwemfuza, ngokukodwa ilungele ukuhanjiswa ngokubambisana kweeplasmids ezininzi.

Ukwengeza,i-polyethyleniminenayo ineempawu zokunamathela okuphezulu, i-adsorption ephezulu, i-cation ephezulu, i-reactivity ephezulu, njl.

Ngokuqhelekileyo, i-polyvinylimide i-polymer eguquguqukayo kunye noluhlu olubanzi lwezicelo, kwaye iimpawu zayo zinokulungelelaniswa kwaye zilungiswe ngokutshintsha ubunzima be-molecular, isakhiwo kunye nokusebenza.
