Polyethylene oxide (PEO)

Polyethylene oxide (PEO), eo hape e tsejoang e le polyethylene glycol (PEG) kapa polyoxyethylene, ke polima e sebetsang ka mefuta e mengata e nang le lits'ebetso tse fapaneng ho pholletsa le liindasteri tse fapaneng. Ke polymer e qhibilihang ka metsing e entsoeng ka ho pheta-pheta li-unit tsa ethylene oxide (-CH2-CH2-O-) 'me e khetholloa ke boima ba eona bo phahameng ba limolek'hule le tlhaho ea hydrophilic. PEO e bonts'a thepa e 'maloa e ikhethang e e etsang hore e tšoanelehe lits'ebetsong tse ngata, ho kenyeletsoa ho qhibiliha ha eona metsing, biocompatibility, le bokhoni ba ho theha tharollo ea viscous. Mona ke lintlha tsa bohlokoa tsa Polyethylene Oxide (PEO) le ts'ebeliso ea eona: 1.Metsi-Solubility: E 'ngoe ea lintho tse bohlokoa ka ho fetisisa tsa PEO ke ho qhibiliha ha eona ho babatsehang metsing. Tšobotsi ena e lumella ho tšoaroa habonolo le ho kenngoa ka har'a litharollo tsa metsi, ho etsa hore e be ea bohlokoa liindastering tse fapa-fapaneng tse kang tsa meriana, tlhokomelo ea botho le lijo. 2.Thickening Agent: PEO e sebelisoa haholo e le moemeli oa ho teteka kapa mofetoleli oa viscosity ka mefuta e sa tšoaneng ea likopo. Ha e qhibiliha ka metsing, limolek'hule tsa PEO lia khomarela 'me li etsa sebopeho sa marang-rang, ho eketsa viscosity ea tharollo. Thepa ena e etsa hore e loketse ho sebelisoa lihlahisoa tse kang lotions, shampoos, le li-detergents tsa metsi. 3.Surface-Active Properties: PEO e ka sebetsa e le moemeli ea sebetsang ka holim'a metsi, e fokotsa tsitsipano ea holim'a metsi le ho ntlafatsa thepa ea ho kolobisa le ho hasana ha tharollo ea metsi. Thepa ena e sebelisoa lits'ebetsong tse kang li-detergents, li-emulsifiers le li-softeners tsa masela. 4. Likopo tsa Pharmaceutical: Lefapheng la meriana, PEO e sebelisoa mekhoeng e sa tšoaneng ea ho fana ka lithethefatsi, ho kenyelletsa le matlapa a laoloang a lokolloa, litharollo tsa molomo, le metsoako ea lihlooho. Ho lumellana ha eona le bioloji, ho qhibiliha ha metsi, le bokhoni ba ho etsa li-gel ho etsa hore e be mothusi ea loketseng bakeng sa litlhare tsa meriana. 5.Binder le Film Former: PEO e ka sebetsa e le setlamo le filimi ea pele matlapeng a meriana, moo e thusang ho kopanya metsoako e sebetsang hammoho le ho fana ka seaparo se boreleli, se tšoanang holim'a letlapa. E boetse e sebelisoa ha ho etsoa lifilimi tse jeoang le ho roala lihlahisoa tsa lijo. 6. Phekolo ea Metsi: PEO e sebelisoa lits'ebetsong tsa ho hloekisa metsi e le thuso ea flocculant le coagulant bakeng sa ho hlakisa le ho hloekisa metsi. E thusa ho kopanya le ho lokisa likaroloana tse emisitsoeng, ho ntlafatsa ts'ebetso ea ts'ebetso ea filthara le sedimentation. 7.Lihlahisoa tsa Tlhokomelo ea Botho: PEO ke motsoako o tloaelehileng oa lihlahisoa tsa tlhokomelo ea botho tse kang sesepa sa meno, ho hlatsoa molomo le lihlahisoa tsa tlhokomelo ea moriri. E sebetsa e le ntho e teteaneng, e tsitsitseng, le e bolokang mongobo, e matlafatsang sebopeho, botsitso le ts'ebetso ea lihlahisoa tsena. Likopo tsa 8.Industrial: PEO e fumana lits'ebetso tse fapaneng tsa indasteri, ho kenyeletsoa ka li-adhesives, coatings, lubricant, le masela. Lits'oants'o tsa eona tsa ho tlotsa li etsa hore e tšoanelehe ho sebelisoa e le ntho e lokollang hlobo, athe bokhoni ba eona ba ho etsa lifilimi bo sebelisoa ho lira le likhomaretsi. 9.Hydrogel Formation: PEO e ka etsa li-hydrogel ha li kopana le li-polymers tse ling kapa lik'hemik'hale tse ling. Li-hydrogel tsena li na le ts'ebeliso ea ho roala maqeba, litsamaiso tsa phepelo ea lithethefatsi, le boenjiniere ba lisele, moo li fanang ka ho boloka mongobo le matrix a tšehetsang kholo ea lisele. Polyethylene Oxide (PEO) ke polima e feto-fetohang e nang le mefuta e mengata ea lits'ebetso ho liindasteri tse ngata. Ho qhibiliha ha eona ka metsi, thepa ea eona e teteaneng, biocompatibility, le litšobotsi tse sebetsang ka holim'a metsi li etsa hore e be ea bohlokoa litabeng tsa meriana, tlhokomelo ea botho, phekolo ea metsi le lisebelisoa tsa indasteri. Ha lipatlisiso le nts'etsopele ea mahlale a polymer li ntse li tsoela pele, PEO e lebelletsoe ho fumana lits'ebetso tse ncha le tse ncha mafapheng a fapaneng.
