Hydroxyethyl Cellulose Eter

Hydroxyethyl cellulose ether waa polymer-ka aan-ionic-ka ahayn ee biyaha ku milma, ku milma biyaha kulul iyo kuwa qabow labadaba.Hydroxyethyl cellulose ether waxay leedahay viscosities ballaaran oo kala duwan, iyo dhammaan xalalka aqueous waa non-Newtonian.

Hydroxyethyl cellulose ether waxay leedahay sifooyin fuuq-bax aad u wanaagsan.Xalka aqueous waa siman oo lebbisan, oo leh dheecaan wanaagsan iyo siman

Kuwa soo socda ayaa ah qaabka ugu habboon ee qaab-dhismeedka molecular ee ether hydroxyethyl cellulose:

N = heerka isku-darka

Waxaa jira saddex kooxood oo hydroxyl ah oo ku yaal unug kasta oo anhydroglucose ah oo ku jira cellulose, kaas oo lagu daaweeyo alkali ee xalka sodium hydroxide ee aqueous si loo helo cusbada sodium cellulose, ka dibna la maro falcelinta etherification leh ethylene oxide si loo sameeyo ether hydroxyethyl cellulose ether.Habka isku-darka HEC, ethylene oxide kaliya kuma beddeli karto kooxaha hydroxyl ee cellulose, laakiin sidoo kale waxay mari kartaa falcelinta silsiladda polymerization ee kooxaha hydroxyl ee kooxaha la beddelay.
