I-Polyethylene oxide (PEO)

I-Polyethylene oxide (PEO), eyaziwa nangokuthi i-polyethylene glycol (PEG) noma i-polyoxyethylene, iyi-polymer eguquguqukayo enezinhlobonhlobo zokusetshenziswa kuzo zonke izimboni ezihlukahlukene.I-polymer encibilikayo emanzini eyakhiwe ngokuphindaphinda amayunithi e-ethylene oxide (-CH2-CH2-O-) futhi ibonakala ngesisindo sayo samangqamuzana aphezulu kanye nemvelo ye-hydrophilic.I-PEO ikhombisa izakhiwo ezimbalwa ezihlukile eziyenza ifanelekele izinhlelo zokusebenza eziningi, okuhlanganisa nokuncibilika kwayo emanzini, i-biocompatibility, kanye nekhono lokwenza izixazululo ze-viscous. Nazi ezinye izici ezibalulekile ze-Polyethylene Oxide (PEO) kanye nokusetshenziswa kwayo: 1.I-Water-Solubility: Enye yezinto ezibaluleke kakhulu ze-PEO ukuncibilika kwayo okuhle kakhulu emanzini.Lesi sici sivumela ukuphathwa kalula nokufakwa ezixazululweni ezinamanzi, okusenza sibe yigugu ezimbonini ezihlukahlukene ezifana nemithi, ukunakekelwa komuntu siqu, nokudla. I-2.I-Thickening Agent: I-PEO isetshenziswa kakhulu njenge-ejenti yokuqina noma i-viscosity modifier kuzinhlelo zokusebenza ezihlukahlukene.Lapho encibilika emanzini, ama-molecule e-PEO ayathandela futhi akhe isakhiwo senethiwekhi, okwandisa i-viscosity yesisombululo.Le ndawo iyenza ifanelekele ukusetshenziswa emikhiqizweni enjengamafutha okugcoba, ama-shampoos, nezihlanzi eziwuketshezi. I-3.Izakhiwo Ezisebenza Phansi: I-PEO ingasebenza njenge-ejenti esebenza phezulu, inciphise ukungezwani kwendawo futhi ithuthukise izakhiwo zokumanzisa nokusabalalisa izixazululo ezinamanzi.Lesi sakhiwo sisetshenziswa ezinhlelweni ezifana nezihlanzi, ama-emulsifiers, nezithambisa izindwangu. 4.Izicelo Zemithi: Embonini yezemithi, i-PEO iqashwe ezinhlelweni ezihlukene zokulethwa kwezidakamizwa, okuhlanganisa amaphilisi akhishwayo okulawulwayo, izixazululo zomlomo, kanye nokwakheka kwezihloko.I-biocompatibility yayo, ukunyibilika kwamanzi, kanye nekhono lokwenza amajeli kuyenza ibe isamukeli esifanelekile sokwakheka kwemithi. I-5.Binder kanye Nefilimu Yangaphambili: I-PEO ingasebenza njenge-binder nefilimu yangaphambili kumaphilisi emithi, lapho isiza khona ukuhlanganisa izithako ezisebenzayo futhi inikeze ukunamathela okubushelelezi, okufanayo endaweni yethebhulethi.Ibuye isetshenziselwe ukwenza amafilimu adliwayo kanye nama-coatings emikhiqizo yokudla. 6. Ukwelashwa Kwamanzi: I-PEO isetshenziswa ekuhlanzeni amanzi njenge-flocculant ne-coagulant aid yokucacisa nokuhlanzwa kwamanzi.Kuyasiza ukuhlanganisa kanye nokuxazulula izinhlayiya ezimisiwe, ukuthuthukisa ukusebenza kahle kwezinqubo zokuhlunga kanye ne-sedimentation. 7.Imikhiqizo Yokunakekelwa Komuntu Siqu: I-PEO iyisithako esivamile emikhiqizweni yokunakekelwa komuntu siqu efana nomuthi wokuxubha, i-mouthwash, nemikhiqizo yokunakekelwa kwezinwele.Isebenza njenge-thickener, stabilizer, kanye ne-ejenti egcina umswakama, ithuthukisa ukuthungwa, ukuzinza, nokusebenza kwale mikhiqizo. Izicelo ze-8.Industrial: I-PEO ithola izinhlelo zokusebenza ezihlukene zezimboni, ezihlanganisa izinto zokunamathisela, okokunamathela, okokugcoba, nezindwangu.Izakhiwo zayo zokugcoba ziyenza ifanelekele ukusetshenziswa njenge-ejenti yokukhulula isikhunta, kuyilapho amakhono ayo okwenza ifilimu asetshenziswa embotsheni nasezinamathelayo. I-9.I-Hydrogel Formation: I-PEO ingenza ama-hydrogel lapho ixhunywe ngokuphambana namanye ama-polymers noma ama-chemical agents.Lawa ma-hydrogel asebenza ekugqokeni amanxeba, ezinhlelweni zokulethwa kwezidakamizwa, kanye nobunjiniyela bezicubu, lapho enikeza khona ukugcinwa komswakama kanye ne-matrix esekelayo yokukhula kwamaseli. I-Polyethylene Oxide (PEO) iyi-polymer eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni eziningi.Ukuncibilika kwayo emanzini, izakhiwo ezijiyayo, i-biocompatibility, nezici ezisebenza phezulu kuyenza ibaluleke kwezemithi, ukunakekelwa komuntu siqu, ukwelashwa kwamanzi, kanye nezicelo zezimboni.Njengoba ucwaningo nokuthuthuka kwesayensi ye-polymer kuqhubeka, i-PEO kulindeleke ukuthi ithole izinhlelo ezintsha nezintsha emikhakheni ehlukahlukene.
