Hydroxyethyl Cellulose Ether

Hydroxyethyl cellulose ether ndi polima wosasungunuka m'madzi, wosungunuka m'madzi otentha komanso ozizira.Hydroxyethyl cellulose ether ili ndi ma viscosities osiyanasiyana, ndipo njira zonse zamadzimadzi sizili za Newtonian.

Hydroxyethyl cellulose ether ili ndi mphamvu zabwino kwambiri za hydration.Njira yake yamadzimadzi ndi yosalala komanso yofananira, yokhala ndi madzi abwino komanso osasunthika

Zotsatirazi ndi njira yabwino yopangira maselo a hydroxyethyl cellulose ether:

N = mlingo wa aggregation

Pali magulu atatu a hydroxyl pa unit iliyonse ya anhydroglucose mu cellulose, yomwe imathandizidwa ndi alkali mumadzimadzi amadzimadzi a sodium hydroxide kuti apeze mchere wamchere wa sodium, ndiyeno amachitira etherification ndi ethylene oxide kupanga hydroxyethyl cellulose ether.M'kati synthesizing HEC, okusayidi ethylene osati m'malo magulu hydroxyl pa mapadi, komanso kukumana unyolo polymerization anachita ndi magulu hydroxyl m'malo magulu.
