Polyethylene Glycol Kiimikada Loo Isticmaalay Warshadaha Daawooyinka

Macluumaadka Alaabta

Polyethylene glycol waa nooc ka mid ah polymer, kaas oo ah nooc ka mid ah Ethylene Warshadaha .

Polyethylene Glycol ayaa loo isticmaalaa
1. Codsiyada biomedical
Polyethylene glycol caafimaad waxaa sidoo kale loo yaqaan polyetylen oxide (PEO). Waa polyeter toosan oo lagu helay polymerization giraanta-furitaanka ee ethylene oxide. Codsiyada ugu muhiimsan ee goobta biomedical waa sida soo socota:
(1) Xalka muraayadaha indhaha. Viscosity ee xalka aqueous ee polyetylen glycol ayaa aad ugu nugul heerka xiirid iyo bakteeriyada ma fududa inay ku koraan glycol polyetylen.
(2) Saliidaha synthetic. polymer-ka uumiga ee ethylene oxide iyo biyaha. Diyaarinta matrix boomaatada dawooyinka biyaha ku milma, sidoo kale waxaa loo isticmaali karaa sida acetylsalicylic acid, caffeine, nimodipine iyo kuwa kale oo ay adag tahay in lagu milmo dareeraha biyaha ee diyaarinta duritaanka.
(3) Side daroogada si tartiib ah u sii deynaya iyo ensaymka aan dhaqdhaqaaqa lahayn. Xalka biyaha leh ee polyetylen glycol waxa lagu dahaadhay lakabka sare ee kiniinka, kaas oo xakamayn kara faafinta daawada gudaha kiniinka ee jidhka si loo hagaajiyo waxtarka daawada.
(4) Wax ka beddelka dusha sare ee alaabta polymer-ka caafimaadka. Isticmaal kopolymer amphiphilic ah oo ay ku jiraan polyetylen glycol si aad u nuugo dusha alaabta polymerka caafimaadka (5) Samee filim alkanol ka hortagga uurka.
(6) Samaynta polyurethane-ka-hortagga xinjirowga dhiigga.
(7) Polyethylene glycol 4000 ee caloosha jilcisa osmotic, ee lumen mindhicirka waxay kordhin kartaa cadaadiska osmotic, nuugista biyaha, si ay saxaradu u jilciso, korodhka mugga, taasoo keenta peristalsis xiidmaha iyo saxarada.
(8) hagaajinta ilkaha. Isticmaalka polyetylen glycol aan sun ahayn iyo koollo, oo loo isticmaalo qayb ka mid ah hagaajinta ilkaha.
(9) daraasadda molecules borotiinka ee tijaabada, waxaad ku ekaan kartaa deegaanka ciriiriga ah ee vivo, si loo xaqiijiyo saameynta deegaanka ciriiriga ah ee qaab dhismeedka borotiinnada.
2. Loo isticmaalo sida cuntada lagu daro
Magaca wax lagu daro: polyetylen glycol
Magaca cuntada loo ogol yahay in lagu daro waxyaabahan: nacnac, dahaarka alaabta shukulaatada
Shaqada wax lagu daro: wakiilka daahan
3.Waxa loo isticmaalaa sidii dhiirigeliyaha fiyuuska
Tani waa dhiirigeliyaha fiyuuska kiimikaad aad u wanaagsan oo loo isticmaalo isku-dhafka protoplastka. Waa polymer ah ethylene glycol, oo leh qaacidada kiimikada HO (CH2CH2O) nH. Waa dhuuban oo cad, xoogaa huruud ah oo u eg, oo biyo ku milmay, lehna ur yar.
4.kale
(1) Loo isticmaalo sida reagent gorfaynta, sidoo kale loo isticmaalo warshadaha dawooyinka;
(2) Loo isticmaalo jilciye, saliid, iwm;
(3) Loo isticmaalo sida matrix ee daawada iyo isqurxinta, kala firdhiya, saliidaha iyo emulsifier ee caagga, farsamaynta birta, sunta cayayaanka iyo warshadaha kale;
Dhexdhexaad u ah isku dhafka dabiiciga ah, qoyaanka maalinlaha ah ee warshadaha qurxinta, solubilizer ee cusbada aan noolaha lahayn, nidaamiyaha viscosity, iwm;
(4) Loo isticmaalo sida flocculant, wakiilka jeexjeexa dareeraha yareeya, wakiilka galitaanka nooca-dharka ah, kaalmaynta xajinta iyo sifaynta, koolada, wakiilada dhumucyada iyo wakiilka hagaajinta ilko;
(5) Loo isticmaalo waxyaabaha la isku qurxiyo, daawooyinka, fiber kiimikaad, caag, warqad, rinji, koronto;
(6) Loo isticmaalo sida wakiilka wax-qabashada, sawirista birta, shaabadeynta iyo jilitaanka, saliidda warshadaha waraaqaha, dareeraha jarista, dareeraha shiididda qaboojinta, wakiilka polishing, iwm.;
(7) Loo isticmaalo sida saliidaha PVC, wax lagu daro masterbatch midabka, jilicsanaanta dunta, kala firdhisanaanta midabka, iwm;
(8) Sida wax lagu daro samaynta waraaqaha, waxay wanaajin kartaa heerka haynta ee buuxinta iyo fiber-ka wanaagsan. Waa anti-flocculant wax ku ool ah. Waxaa lagu dari karaa tubbada si loo hagaajiyo viscosity ee saxarka, ka hortagga fiyuusyada inay isku dhejiyaan midba midka kale, hagaajinta isku midka ah ee warqadda, hoos u dhigista isticmaalka awoodda pulping, iyo hagaajinta xoogga jirka.
