Hydroxyethyl Cellulose e sebelisetsoa eng?

Hydroxyethyl cellulose(HEC) ke ether e seng ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer ka letoto la etherification.Ke phofshoana e tšoeu e sa nkheng, e sa latsoeheng, e se nang chefo kapa granule, e ka qhibilihang metsing a batang ho etsa tharollo e hlakileng ea viscous, 'me ho qhibiliha ha ho amehe ke boleng ba pH.E na le ho teteana, ho tlama, ho qhalakanya, emulsifying, ho etsa filimi, ho emisa, ho bapatsa, ho sebetsa ka holim'a metsi, ho boloka mongobo le ho thibela letsoai.E sebelisoa haholo ho penta, kaho, masela, lik'hemik'hale tsa letsatsi le letsatsi, pampiri, ho cheka oli le liindasteri tse ling.
