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. Njenge-arhente yamandla emanzi, isetyenziswa kwiphepha lokufunxa elingummed (elifana nephepha lokucoca, iphepha lokusula inki, iphepha lendlu yangasese, njl.njl.), elinokuphucula amandla amanzi ephepha kunye nokunciphisa umonakalo wokusetyenzwa kwephepha, ngelixa isantya ukuhluzwa kwamanzi kwi-pulp kunye nokwenza iintsinga ezintle zibe lula ukudada.

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, ezifana nezixhobo 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 kwegesi okulungileyo, okungeyona ityhefu, ukunambitha, ukumelana nobushushu obuphezulu, njl., kwaye isetyenziswa ngokubanzi kwipakethe yenyama, iinkukhu, iziqhamo, imifuno, ikofu kunye ezinye 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 kofuzo, ngokukodwa ilungele ukuhanjiswa ngokubambisana kweeplasmids ezininzi.

Ukwengeza,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.
