Selulose ether e boloka metsi joang?

Hydroxypropyl methylcellulose ke ether e seng ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer ka letoto la lits'ebetso tsa lik'hemik'hale. Ke mofuta oa phofo e tšoeu e se nang monko, e sa nkheng, e se nang chefo, e kokomohang metsing a batang 'me e bitsoa tharollo ea colloidal e hlakileng kapa e nang le maru hanyenyane. E na le thepa ea ho tiisa, ho tlama, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, surface active, ho boloka mongobo le ho sireletsa colloid.

Hydroxypropyl methylcellulose e ntle haholo e ka rarolla bothata ba ho boloka metsi tlas'a mocheso o phahameng. Linakong tsa mocheso o phahameng, haholo-holo libakeng tse chesang le tse omileng le kaho ea lera le tšesaane lehlakoreng le chabileng, ho hlokahala HPMC hydroxypropyl methylcellulose ea boleng bo holimo ho ntlafatsa ho boloka metsi a seretse.

Hydroxypropyl methylcellulose ea boleng bo holimo e na le ho tšoana ho hoholo. Lihlopha tsa eona tsa methoxy le hydroxypropoxy li ajoa ka ho lekana hammoho le ketane ea molek'hule ea cellulose, e ka ntlafatsang liathomo tsa oksijene ho hydroxyl le ether bond le mokhatlo oa metsi. Bokhoni ba ho kopanya le ho theha maqhama a haedrojene a fetola metsi a mahala hore e be metsi a tlamiloeng, ka hona a laola ka nepo ho tsoa mouoane ha metsi ho bakoang ke mocheso o phahameng oa leholimo le ho fihlela ho boloka metsi a mangata.
