Polyethylene Glycol 2000

CAS TSIS MUAJ .: 25322-68-3

Polyethylene Glycol 2000 yog hom kev ua yeeb yam zoo, che ch2ch2o) NH, iab iab, muaj ntau cov organic muaj kev sib raug zoo. Nrog rau covric dej zoo heev, noo noo, dispersion, yuav siv tau los ua tshuaj pleev ib ce, thiab lwm yam tshuaj tua kab, tshuaj lom neeg muaj kev lag luam ntau yam muaj ntau yam.

Lub ntsiab siv

Polyethylene glycol thiab polyethylene glycol fatty acid ester yog dav siv hauv kev lag luam tshuaj pleev ib ce thiab kev lag luam kws tshuaj. Vim tias polyethylene glycol muaj ntau cov khoom muaj ntau yam: cov dej solubility, tsis muaj zog, lub cev nqaij daim tawv, mos, qab ntxiag tom qab siv. Polyethylene glycol nrog cov txheeb ze sib txawv molecular qhov hnyav cov qhab nia tuaj yeem xaiv tau los hloov viscosity, hygroscopicity thiab qauv ntawm cov khoom. Tsawg molecular hnyav polyethylene glycol (mr <2000) haum rau siv ua cov tshuaj pleev xim, siv rau cov plaub hau kev saib xyuas plaub hau, kuj tau muab plaub hau muaj plaub hau ci ci. High molecular hnyav polyethylene glycol (Mr> 2000) rau mem pleev di ncauj, deodorant lo, xab npum, lub hauv paus thiab cov tshuaj pleev ib ce. Hauv kev ntxuav cov neeg sawv cev, polyethylene glycol kuj tau siv los ua tus neeg sawv cev ncua thiab tuab. Hauv kev lag luam kws tshuaj, nws yog siv los ua tshuaj pleev xim rau tshuaj pleev, emulsions, tshuaj pleev, tshuaj pleev, cov tshuaj pleev thiab cov khoom noj.

Polyethylene Glycol 2000 yog dav siv nyob rau hauv ntau yam ntawm ntau ntawm cov kev npaj tshuaj, xws li txhaj tshuaj, cov ntsiab lus, thiab kev npaj lub cev, thiab lub qhov ncauj, thiab kev npaj khoom siv. Hnyog qib polyethylene glycol tuaj yeem ntxiv rau kua polyethylene glycol kom kho lub viscosity rau tshuaj pleev hauv zos; Polyethylene glycol sib tov tuaj yeem siv ua cov roj av substrate. Cov tshuaj aqueous ntawm polyethylene glycol tuaj yeem siv los ua kev pab raug tshem tawm lossis kho cov viscosity ntawm lwm cov xov xwm. Kev sib xyaw ntawm polyethylene glycol thiab lwm yam emulsifiers nce qhov ruaj khov ntawm emulsion. Tsis tas li ntawd, Polyethylene glycol kuj tau siv ua zaj duab xis txheej tus neeg sawv cev, ntsiav tshuaj roj nplua nyeem, cov roj nplua nyeem, thiab lwm yam.
