PEO-Polyethylene Oxide hmoov

Polyethylene oxide (PEO) hmoov, tseem hu ua polyethylene glycol (PEG) hmoov, yog ib daim ntawv ntawm PEO uas feem ntau pom nyob rau hauv cov khoom, hmoov. PEO hmoov yog muab los ntawm polymerization ntawm ethylene oxide monomers thiab yog tus cwj pwm los ntawm nws qhov hnyav molecular thiab dej-soluble xwm. Nws muaj ntau yam kev siv thoob plaws ntau yam kev lag luam vim nws cov khoom tshwj xeeb thiab ntau yam.

Cov khoom tseem ceeb ntawm PEO Hmoov:

1.High Molecular Luj: PEO hmoov feem ntau muaj qhov hnyav molecular, uas ua rau nws cov thickening thiab film-forming zog thaum yaj hauv dej. Qhov hnyav molecular tuaj yeem sib txawv nyob ntawm qib tshwj xeeb lossis kev tsim ntawm PEO hmoov.

2. Dej Solubility: Zoo ib yam li lwm hom PEO, PEO hmoov yog soluble hauv dej, sib sau ua kua, kua nplaum. Cov cuab yeej no ua rau nws yooj yim los lis thiab sib xyaw ua ke hauv cov dej hauv dej thiab ua rau nws siv ntau yam kev siv.

3.Viscosity Modifier: PEO hmoov feem ntau yog siv los ua viscosity modifier lossis thickening tus neeg sawv cev hauv cov tshuaj aqueous. Thaum yaj nyob rau hauv dej, lub polymer chains ntawm PEO entangle thiab tsim ib tug network qauv, nce viscosity ntawm cov tshuaj. Cov cuab yeej no muaj txiaj ntsig zoo hauv kev lag luam xws li tshuaj pleev ib ce, tshuaj, thiab zaub mov, qhov twg yuav tsum muaj kev tswj xyuas meej ntawm viscosity.

4.Film-Forming Muaj peev xwm: PEO hmoov muaj peev xwm tsim cov yeeb yaj kiab thaum yaj hauv dej thiab tso cai kom qhuav. Cov yeeb yaj kiab no yog pob tshab, hloov tau yooj yim, thiab pom zoo adhesion rau ntau qhov chaw. PEO films yog siv rau hauv daim ntawv thov xws li txheej, nplaum, thiab cov khoom ntim.

5.Biocompatibility: PEO hmoov feem ntau suav hais tias yog biocompatible thiab tsis muaj tshuaj lom, ua rau nws tsim nyog rau kev siv tshuaj, khoom tu tus kheej, thiab kev siv khoom noj. Nws yog dav siv los ua ib qho excipient nyob rau hauv cov tshuaj formulations thiab ua ib tug muaj nyob rau hauv lub qhov ncauj cov khoom, tshuaj pleev ib ce, thiab zaub mov additives.

Kev siv PEO hmoov:

1.Pharmaceuticals: PEO hmoov yog siv rau hauv cov tshuaj formulations raws li ib tug binder, disintegrant, thiab tswj-tso tus neeg saib xyuas nyob rau hauv cov ntsiav tshuaj thiab tsiav tshuaj. Nws pab txhim kho cov solubility, bioavailability, thiab stability ntawm active tshuaj cov khoom xyaw.

2. Cov Khoom Siv Kho Tus Kheej: PEO hmoov yog cov khoom muaj nyob rau hauv cov khoom siv tu tus kheej xws li tshuaj pleev xim, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav. Nws ua haujlwm ua cov thickener, stabilizer, thiab emulsifier, txhim kho kev ntxhib los mos, ruaj khov, thiab kev ua haujlwm ntawm cov khoom no.

3.Food Additives: PEO hmoov yog siv los ua khoom noj khoom haus hauv ntau yam khoom noj, nrog rau cov khoom ci, khoom noj siv mis, thiab khoom qab zib. Nws ua hauj lwm raws li ib tug thickener, gelling tus neeg saib xyuas, thiab noo noo-retaining tus neeg saib xyuas, txhim kho kev ntxhib los mos, qhov ncauj, thiab txee lub neej ntawm cov khoom noj.

4.Industrial Applications: PEO hmoov pom cov ntawv thov nyob rau hauv ntau yam kev lag luam, nrog rau cov nplaum, coatings, lubricants, thiab textiles. Nws yog siv los ua ib daim ntawv khi, zaj duab xis qub, thiab kev hloov kho rheology hauv cov ntawv thov no, muab kev ua tau zoo thiab kev ua haujlwm zoo.

5.Kev kho dej: PEO hmoov yog ua haujlwm hauv cov ntawv thov kev kho dej ua cov flocculant thiab coagulant pab rau kev qhia meej thiab kev ua kom huv ntawm cov dej. Nws pab kom sib sau ua ke thiab daws cov teeb meem tshem tawm, txhim kho kev ua haujlwm ntawm kev pom thiab cov txheej txheem sedimentation.

Polyethylene oxide PEO hmoov yog ntau yam polymer nrog ntau yam kev siv thoob plaws ntau qhov kev lag luam. Nws qhov hnyav molecular, dej solubility, viscosity-hloov zog, thiab biocompatibility ua rau nws muaj txiaj ntsig zoo hauv kev siv tshuaj, kev saib xyuas tus kheej, zaub mov, thiab kev siv hauv kev lag luam. Raws li kev tshawb fawb thiab kev loj hlob hauv kev tshawb fawb polymer txuas ntxiv mus, PEO hmoov yuav tsum nrhiav kev siv tshiab thiab tshiab hauv ntau yam.
