Hydroxyethyl Cellulose Eter

O le Hydroxyethyl cellulose ether o se polymer e le mafai ona solu i le vai, e mafai ona solu i vai vevela ma vai malulu.O le Hydroxyethyl cellulose ether e iai le tele o viscosities, ma o vaifofo uma e le o ni Newtonian.

O le Hydroxyethyl cellulose ether o loʻo i ai mea faʻamamaina lelei.O lona vaifofo vai e lamolemole ma toniga, ma lelei le suavai ma le fa'asa'oina

O loʻo taua i lalo le faʻatulagaga mole mole lelei o le hydroxyethyl cellulose ether:

N = tikeri o le tuufaatasiga

E tolu vaega hydroxyl i luga o iunite anhydroglucose taitasi i le cellulose, lea e togafitia i le alkali i le vai o le sodium hydroxide solution e maua ai le masima sodium cellulose, ona faia lea o le etherification reaction ma le ethylene oxide e fausia ai le hydroxyethyl cellulose eter.I le faagasologa o le faʻapipiʻiina o le HEC, o le ethylene oxide e le gata e mafai ona suitulaga i vaega o le hydroxyl i luga o le cellulose, ae o loʻo i ai foi se tali polymerization filifili ma vaega hydroxyl i vaega sui.
