Hydroxyethyl celluloseHECke polima e qhibilihang ka metsing e seng ionic e qhibilihang metsing a chesang le a batang. Letoto la Hydroxyethylcellulose HEC le na le mefuta e mengata ea li-viscosities, 'me litharollo tsa metsi ke maro a seng a Newtonian.
Hydroxyethyl cellulose ke tlatsetso ea bohlokoa lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale. E ke ke ea ntlafatsa feela viscosity ea litlolo tsa mokelikeli kapa emulsion, empa hape e ntlafatsa ho hasana le botsitso ba foam.
molemo:
1.E na le hydration e ntle haholo.
2. E na le botsitso bo boholo le botlalo.
3. Thepa e ntle haholo ea ho etsa lifilimi.
4. E na le ts'ebetso e phahameng haholo ea litšenyehelo.
5.E na le tekanyo e babatsehang ea ho kenya sebaka ho netefatsa botsitso ba nako e telele bo khahlanong le hlobo ea sehlahisoa.
Tekanyo ea polymerization:
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 hydroxyethyl cellulose, ethylene oxide e ka nka sebaka sa lihlopha tsa hydroxyl ho selulose, 'me ea etsa ketane ea polymerization le lihlopha tsa hydroxyl ka lihlopha tse nketsoeng sebaka.
Hydroxyethyl cellulose 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. Ka hona, litlolo tse nang le hydroxyethyl cellulose li na le botsitso bo botle le botlalo ka har'a setshelo, 'me li hasana habonolo holim'a moriri le letlalo ha li sebelisoa. E sebelisoa haholo ho li-conditioner, lihlatsoa tsa 'mele, sesepa sa metsi, li-gels tsa ho kuta le li-foam, sesepa sa meno, li-deodorants tse tiileng, li-tissue (masea le batho ba baholo), li-gel tse tlotsang.
Ho phaella tabeng ea ho laola metsi,hydroxyethyl cellulosee na le litšobotsi tse ntle tsa ho etsa lifilimi. Filimi e entsoeng e tiisitsoe hore e tla ba boemong bo feletseng tlas'a 350x le 3500x seipone sa seipone, 'me e tlisa boikutlo bo botle ba letlalo ha e sebelisoa ho litlolo.
