Hydroxyethyl Cellulose Ether

Hydroxyethyl cellulose ether ke polima e qhibilihang ka metsing e seng ionic, e qhibilihang metsing a chesang le a batang.Hydroxyethyl cellulose ether e na le mefuta e mengata ea li-viscosities, 'me litharollo tsohle tsa metsi ha li Newtonian.

Hydroxyethyl cellulose ether e na le thepa e ntle haholo ea hydration.Tharollo ea eona ea metsi e boreleli ebile e tšoana, e na le metsi a matle le ho lekana

E latelang ke mokhoa o nepahetseng oa sebopeho sa limolek'hule tsa hydroxyethyl cellulose ether:

N = tekanyo ea ho kopanya

Ho na le lihlopha tse tharo tsa hydroxyl yuniti e 'ngoe le e' ngoe ea anhydroglucose ka selulose, e tšoaroang ka alkali ka har'a tharollo ea sodium hydroxide e nang le selulose letsoai, ebe e kenella karabelo ea etherification ka ethylene oxide ho theha hydroxyethyl cellulose ether.Ts'ebetsong ea ho kopanya HEC, ethylene oxide e ke ke ea nka sebaka sa lihlopha tsa hydroxyl ka selulose feela, empa hape e ka ba le karabelo ea ketane ea polymerization le lihlopha tsa hydroxyl lihlopheng tse nketsoeng sebaka.
