I-Polyethylene oxide (PEO)

I-Polyethylene oxide (PEO), ekwabizwa ngokuba yi-polyethylene glycol (PEG) okanye i-polyoxyethylene, yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. I-polymer e-soluble yamanzi ehlanganiswe ngokuphindaphindiweyo kweeyunithi ze-ethylene oxide (-CH2-CH2-O-) kwaye ibonakaliswe ngobunzima bayo be-molecular kunye nendalo ye-hydrophilic. I-PEO ibonisa iipropathi ezininzi ezizodwa eziyenza ilungele izicelo ezininzi, kubandakanya ukunyibilika kwayo emanzini, ukuhambelana kwezinto eziphilayo, kunye nokukwazi ukwenza izisombululo ze-viscous. Nantsi eminye imiba ephambili yePolyethylene Oxide (PEO) kunye nokusetyenziswa kwayo: 1.Ukunyibilika kwamanzi: Enye yezona zinto zibalulekileyo ze-PEO kukunyibilika kwayo okugqwesileyo emanzini. Olu phawu luvumela ukuphathwa ngokulula kunye nokudityaniswa kwizisombululo ezinamanzi, kuyenza ixabiseke kumashishini ahlukeneyo afana namayeza, ukhathalelo lomntu, kunye nokutya. I-Agent ye-2.Thickening: I-PEO isetyenziswa ngokubanzi njenge-ejenti yokuqina okanye i-viscosity modifier kwizicelo ezahlukeneyo. Xa ichithwa emanzini, ii-molecule ze-PEO zidibanisa kwaye zenze isakhiwo senethiwekhi, ukwandisa i-viscosity yesisombululo. Le propati iyenza ilungele ukusetyenziswa kwiimveliso ezifana ne-lotions, i-shampoos, kunye nezicoci zolwelo. I-3.IiPropati eziSebenzayo zoMgangatho: I-PEO inokusebenza njenge-arhente esebenza phezulu, ukunciphisa ukuxhatshazwa kwendawo kunye nokuphucula ukumanzisa kunye nokusabalalisa iipropati zezisombululo zamanzi. Lo mhlaba usetyenziswa kwizicelo ezifana nezicoci, izithambiso, nezithambisi zelaphu. I-4.Izicelo ze-Pharmaceutical: Kwishishini lamachiza, i-PEO iqeshwe kwiinkqubo ezahlukeneyo zokuhanjiswa kweziyobisi, kubandakanywa iipilisi ezikhutshwayo ezilawulwayo, izisombululo zomlomo, kunye ne-topical formulations. I-biocompatibility yayo, ukunyibilika kwamanzi, kunye nokukwazi ukwenza iijeli kwenza ukuba ibe ngumxhasi ofanelekileyo wokuqulunqwa kwamayeza. I-5.I-Binder kunye neFilimu yangaphambili: I-PEO inokusebenza njenge-binder kunye nefilimu yangaphambili kwiipilisi zamachiza, apho inceda ukubopha izithako ezisebenzayo kunye nokubonelela ngokugudileyo, ukugqoka okufanayo kwi-tablet surface. Ikwasetyenziswa ekwenzeni iifilim ezityiwayo kunye nokwaleka kweemveliso zokutya. 6. Ukucocwa kwamanzi: I-PEO isetyenziselwa ukusetyenziswa kwamanzi njenge-flocculant kunye ne-coagulant aid yokucacisa kunye nokucocwa kwamanzi. Inceda ukudibanisa kunye nokuhlalisa amaqhekeza amisiweyo, ukuphucula ukusebenza kakuhle kweenkqubo zokuhluza kunye ne-sedimentation. I-7.Iimveliso zoNyango loMntu: I-PEO yinto eqhelekileyo kwiimveliso zokunyamekela komntu ezifana ne-toothpaste, i-mouthwash, kunye nemveliso yokunakekelwa kweenwele. Isebenza njenge-thickener, stabilizer, kunye ne-arhente yokugcina ukufuma, iphucula ukuthungwa, ukuzinza, kunye nokusebenza kwezi mveliso. 8.Iinkqubo zokuSebenza kwaMashishini: I-PEO ifumana usetyenziso olwahlukeneyo lwemizi-mveliso, kubandakanywa izinto zokuncamathelisa, iingubo, izinto zokuthambisa, kunye namalaphu. Iimpawu zayo zokuthambisa zenza ukuba ilungele ukusetyenziswa njenge-arhente yokukhupha i-mold, ngelixa ubuchule bayo bokwenza ifilimu busetyenziselwa iingubo kunye ne-adhesives. I-9.Hydrogel Formation: I-PEO inokwenza i-hydrogels xa idibene nezinye iipolymers okanye i-chemical agents. Ezi hydrogels zinezicelo kwiingubo zenxeba, iinkqubo zokuhanjiswa kweziyobisi, kunye nobunjineli bezicubu, apho zibonelela ngokugcinwa komswakama kunye ne-matrix exhasayo yokukhula kweeseli. I-Polyethylene Oxide (PEO) yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo kumashishini amaninzi. Ukunyibilika kwayo kwamanzi, iipropathi ezityebileyo, i-biocompatibility, kunye neempawu ezisebenzayo kumphezulu ziyenza ixabiseke kumayeza, ukhathalelo lomntu, unyango lwamanzi, kunye nokusetyenziswa kwemizi-mveliso. Njengoko uphando kunye nophuhliso kwisayensi yepolymer luqhubeka, i-PEO kulindeleke ukuba ifumane usetyenziso olutsha kunye nolutsha kwiinkalo ezahlukeneyo.
