Polyethylene Oxide (PEO)

Polyethylene oxide (PEO), oo sidoo kale loo yaqaan polyetylen glycol (PEG) ama polyoxyethylene, waa polymer isku dhafan oo leh codsiyo ballaaran oo warshado kala duwan ah.Waa polymer-ka biyaha-milmi kara oo ka kooban unugyada ethylene oxide ee soo noqnoqda (-CH2-CH2-O-) waxaana lagu gartaa miisaankeeda kelliyada sare iyo dabeecadda hydrophilic.PEO waxay soo bandhigtaa dhowr siyaalood oo gaar ah oo ka dhigaya mid ku habboon codsiyo badan, oo ay ku jiraan ku milmitaankeeda biyaha, biocompatibility, iyo awoodda samaynta xalalka viscous. Waa kuwan qaar ka mid ah dhinacyada muhiimka ah ee Polyethylene Oxide (PEO) iyo codsiyadeeda: 1.Water-Solubility: Mid ka mid ah sifooyinka ugu muhiimsan ee PEO waa milanka aadka u fiican ee biyaha.Dabeecaddani waxay u oggolaanaysaa in si sahlan loo maareeyo oo lagu daro xalalka aqueous, taasoo ka dhigaysa mid qiimo leh warshadaha kala duwan sida daawooyinka, daryeelka shakhsi ahaaneed, iyo cuntada. 2.Wakiilka Dhumucda: PEO waxaa si ballaaran loo isticmaalaa sida wakiilka dhumuc ama beddelka viscosity ee codsiyada kala duwan.Marka lagu milmo biyaha, molecules PEO waxay isku xiraan oo sameeyaan qaab-dhismeedka shabakad, kordhinta viscosity ee xalka.Gurigan wuxuu ka dhigayaa mid ku habboon in loo isticmaalo alaabada sida loshinka, shambooyinka, iyo saabuunta dareeraha ah. 3.Surface-Active Properties: PEO waxay u dhaqmi kartaa sida wakiilka firfircoon ee dusha sare, yaraynta xiisadda dusha sare iyo hagaajinta qoynta iyo faafinta sifooyinka xalalka aqueous.Gurigan waxaa loo adeegsadaa codsiyada sida saabuunta, emulsifiers, iyo jilciyaasha dharka. Codsiyada 4.Pharmaceutical: Warshadaha dawooyinka, PEO waxay ka shaqeysaa nidaamyada gudbinta daroogada ee kala duwan, oo ay ku jiraan kiniiniyada la sii daayo, xalalka afka, iyo qaabaynta jirka.Laqabsigeeda noole, milmaynaanshaha biyaha, iyo awooda samaynta jel-ka ayaa ka dhigaysa wax-soo-saarka ugu fiican ee habaynta dawooyinka. 5.Binder iyo Film hore: PEO waxay u adeegi kartaa sidii binder iyo filim hore oo kiniiniyada dawooyinka ah, halkaas oo ay ka caawiso in ay isku xidho maaddooyinka firfircoon ee wadajirka ah iyo bixinta siman, dahaarka lebis ee dusha kiniinka.Waxa kale oo loo isticmaalaa soo saarista filimada la cuni karo iyo dahaarka alaabta cuntada. 6. Daaweynta Biyaha: PEO waxaa loo isticmaalaa codsiyada daaweynta biyaha sidii gargaar faleebo iyo xinjirowga dhiigga si loo caddeeyo loona sifeeyo biyaha.Waxay ka caawisaa in la isku geeyo oo la dejiyo qaybaha la hakiyey, hagaajinta waxtarka sifaynta iyo hababka sedimentation. 7.Alaabooyinka Daryeelka Shakhsiyeed: PEO waa shay caadi ka ah alaabta daryeelka shakhsi ahaaneed sida daawada cadayga, dhaqidda afka, iyo alaabta timaha lagu daryeelo.Waxay u shaqeysaa sidii dhumuc weyn, xasiliye, iyo wakiilka qoyaanka-haysta, kor u qaadida qaab-dhismeedka, xasilloonida, iyo waxqabadka alaabtan. Codsiyada 8.Industrial: PEO waxay heshaa codsiyo warshadeed oo kala duwan, oo ay ku jiraan xabagta, dahaarka, saliidaha, iyo dunta.Alaabta saliidda leh waxay ka dhigaysaa mid ku habboon in loo isticmaalo sida wakiilka sii daaya caaryada, halka awoodeeda filim samaynta loo isticmaalo daaha iyo xabagta. 9.Hydrogel Formation: PEO waxay samayn kartaa hydrogels marka la isku xiro polymers kale ama walxaha kiimikada.Hydrogels-yadani waxay leeyihiin codsiyo ku saabsan dhaymada nabarrada, hababka gudbinta daroogada, iyo injineernimada unugyada, halkaas oo ay ku bixiyaan haynta qoyaanka iyo shax taageerada koritaanka unugyada. Polyethylene Oxide (PEO) waa polymer isku dhafan oo leh codsiyo kala duwan oo warshado badan ah.Biyuhu milmayntooda, sifooyinka dhumucdooda, biocompatibility, iyo sifooyinka firfircoon ee dusha sare ayaa ka dhigaya mid qiimo leh daawooyinka, daryeelka shakhsi ahaaneed, daaweynta biyaha, iyo codsiyada warshadaha.Sida cilmi-baarista iyo horumarinta sayniska polymer-ka ay sii socdaan, PEO waxaa la filayaa inay hesho codsiyo cusub oo cusub oo dhinacyo kala duwan ah.
