I-Polyethylenimine (PEI)yipolymer enyibilikayo emanzini. Uxinzelelo emanzini kwiimveliso zorhwebo ludla ngokuba yi-20% ukuya kwi-50%. I-PEI yenziwe ipolymer kwi-ethylene imide monomer. Yipolymer ye-cationic edla ngokubonakala njengolwelo olungenambala ukuya kolutyheli okanye oluqinileyo olunobunzima obahlukeneyo beemolekyuli kunye neendidi ezahlukeneyo zesakhiwo.

Yintoni ii-polyethyleneimineumsebenzi?

1. Iqela le-amino elinamathelayo kakhulu, elifunxayo kakhulu linokusabela neqela le-hydroxyl ukwenza i-hydrogen bond, iqela le-amine linokusabela neqela le-carboxyl ukwenza i-ionic bond, iqela le-amine linokusabela neqela le-carbon acyl ukwenza i-covalent bond. Kwangaxeshanye, ngenxa yesakhiwo sayo se-polar group (amine) kunye neqela le-hydrophobic (vinyl), inokudityaniswa nezinto ezahlukeneyo. Ngala mandla apheleleyo okubopha, ingasetyenziswa kakhulu kwicandelo lokutywina, i-inki, ipeyinti, i-binder njalo njalo.

2. I-polyvinyl imide ene-cationic ephezulu ikhona ngohlobo lwe-polycation emanzini, enokuthi inciphise kwaye ifunxe zonke izinto ze-anionic. Ikwasusa ii-ion zesinyithi esinzima. Ngenxa yeempawu zayo eziphezulu ze-cationic, ingasetyenziswa ekwenzeni iphepha, ekunyangweni kwamanzi, kwisisombululo seplating, kwi-dispersant nakwezinye iindawo.

3. I-polyethylenimine esabela kakhulu ngenxa yee-amine eziphambili nezesibini ezisabela kakhulu, ngoko ke inokusabela ngokulula kwi-epoxy, ii-asidi, iikhompawundi ze-isocyanate kunye neegesi ze-asidi. Isebenzisa le mpawu, ingasetyenziswa njenge-epoxy reactant, i-aldehyde adsorbent kunye ne-agent yokulungisa umbala.

Isetyenziselwa ntoni i-polyethylenimine?

I-Polyethylenimine (PEI)yi-polymer compound eguquguqukayo eneendlela ezahlukeneyo zokusetyenziswa, kuquka kodwa kungaphelelanga apho:

1. Unyango lwamanzi kunye noshishino lwephepha. Njengesixhobo sokuqinisa amanzi, sisetyenziswa kwiphepha elingafunxwanga (njengephepha lokucoca, iphepha lokufunxa i-inki, iphepha langasese, njl.njl.), elinokuphucula amandla okumanzi ephepha kwaye linciphise umonakalo wokucubungula iphepha, ngelixa likhawulezisa ukuhluzwa kwamanzi kwi-pulp kwaye lenze imicu emincinci ibe lula ukuyithunga.

2. Iarhente yokulungisa imibala. Inamandla amakhulu okubopha iidayi ze-asidi kwaye ingasetyenziswa njengearhente yokulungisa xa iidayi ze-asidi zipeyinta iphepha ledayi.

3. Ukuguqulwa kwefayibha kunye nezixhobo zokufaka idayi. Zonyango lwefayibha, ezifana nezixhobo zokuzikhusela emzimbeni, iiglavu ezithintela ukusika, intambo, njl.njl.

4. Izixhobo ze-elektroniki. Kwicandelo le-elektroniki, ifilimu ye-polyethylene imide ingasetyenziswa njengomaleko owahlulayo, izinto zokukhusela ubushushu kunye nomaleko wokugquma wezixhobo ze-elektroniki, njl.njl., kunye nokusebenza kakuhle kokukhusela ubushushu kunye nokumelana nobushushu obuphezulu.

5. Ukupakisha ukutya. Njengesixhobo sokupakisha ukutya, sineengenelo zokumelana nokufuma, ukumelana negesi kakuhle, ukungatyi tyhefu, ukunganambitheki, ukumelana nobushushu obuphezulu, njl.njl., kwaye sisetyenziswa kakhulu ekupakisheni inyama, iinkukhu, iziqhamo, imifuno, ikofu nezinye iimveliso.

6. Izixhobo zonyango. I-Polyvinylimine ingasetyenziswa kwizixhobo zonyango, izixhobo zokuxilonga, ukupakishwa kwezonyango, njl.njl., ezinje ngeebhanti zonyango kunye neefilimu zonyango ezicacileyo.

7. I-Adhesive. Njenge-adhesive esebenza kakhulu, isetyenziswa ekwenziweni kwee-aerospace, izinto ze-elektroniki, iindawo zeemoto njalo njalo.

8. Izinto zokunyanga amanzi kunye nezinto zokusasazeka emanzini. Isetyenziswa kakhulu ekwenzeni iphepha lokunyanga amanzi, isisombululo se-electroplating, i-dispersant kunye nezinye iindawo. I-Gene carrier. I-Polyvinylimide yivektha engeyiyo intsholongwane yokuhambisa ii-gene, ifanelekile ngakumbi ekudluliseleni ii-plasmids ezininzi kunye.

Ukwengeza,i-polyethylenimineIkwanazo neempawu zokunamathela okuphezulu, ukufunxa okuphezulu, i-cation ephezulu, ukusebenza okuphezulu, njl.njl., kwaye ikwasetyenziswa kakhulu kwicandelo lepeyinti, i-inki, i-adhesive, unyango lwefayibha, unyango lwelindle njalo njalo.

Ngokubanzi, i-polyvinyllimide yi-polymer eguquguqukayo eneendlela ezahlukeneyo zokusetyenziswa, kwaye iipropati zayo zinokulungiswa kwaye ziphuculwe ngokutshintsha ubunzima beemolekyuli, ulwakhiwo kunye nokusebenza kwazo.
