HydroxyPropyyl methylulose, tseem hu ua hypromellose thiab cellulose hydroxypropyl metylrope thiab yog tshwj xeeb heev rau hauv alkaline tej yam kev mob.
Qhov sib txawv:
Cov yam ntxwv sib txawv
HydroxyPropyyl methylulose: Dawb fiber ntau-zoo li hmoov lossis granules hauv ntau hom sib xyaw, cov khoom lag luam no yog ib qho hluav taws xob semi-awactictic polymer.
Hydroxyethyl cellulose yog dawb lossis daj, tsis muaj kuab lom lossis cov hmoov nplej tsw qab yog alkali cellulose, uas yog ib qho tsis-ionic cellulose ether.
Siv yog txawv
Hauv kev lag luam pleev xim, hydroxypropy muaj solubility muaj solubility zoo nyob rau hauv dej lossis organic kuab tshuaj los ua cov tuab, dispersant thiab stabilizer thiab stabilizer. Polyvinyl chloride yog siv los ua cov pleev xim remover rau kev tso cai rau polyvinyl chloride, cov txiv hmab txiv ntoo thiab zaub thiab lwm yam lag luam.
HydroxyPropyyl methylulose: yuav luag Insoluble nyob rau hauv abcute ethanol, ether, acetone; Soluble hauv pob tshab lossis turbid colloidal tov hauv dej txias, papermetics, tshuaj tua kab, tshuaj tua kab, roj rov qab thiab khoom siv tshuaj.
txawv solubility
HydroxyPropyyl methylulose: yuav luag Insoluble nyob rau hauv abcute ethanol, ether, acetone; Soluble nyob rau hauv meej los yog me ntsis pos huab colloidal tov hauv dej txias.
Hydroxyethyl cellulose (HEC): Nws tuaj yeem npaj cov kev daws teeb meem hauv viscosity sib txawv, thiab muaj cov ntsev zoo nkauj rau electrolytes.
