Mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) e sebelisoa haholo linthong tsa kaho, liphahlo, li-resin tsa maiketsetso, lirafshoa, meriana, lijo, masela, temo, litlolo, koae le liindasteri tse ling. Hydroxypropyl methylcellulose (HPMC) ke ether e seng ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer ka letoto la lits'ebetso tsa lik'hemik'hale. Hydroxypropylmethylcellulose (HPMC) ke phofo e tšoeu e se nang monko, e sa latsoeheng, e se nang chefo e ka qhibilihang ka metsing a batang ho etsa tharollo e hlakileng ea viscous. E na le litšoaneleho tsa ho teteana, ho tlama, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, surface active, ho boloka mongobo le ho sireletsa colloid.

Mokhoa oa ho qhibiliha oa hydroxypropyl methylcellulose (HPMC):

Sehlahisoa sena se kokomoha ebe se hasana metsing a chesang a ka holimo ho 85°C, 'me hangata se qhibiliha ka mekhoa e latelang:

1. Nka 1/3 ea palo e hlokahalang ea metsi a chesang, hlohlelletsa ho qhibiliha ka ho feletseng sehlahisoa se ekelitsoeng, ebe u eketsa metsi a mang a chesang, a ka bang metsi a batang, kapa esita le metsi a leqhoa, 'me u hlohlelletse ho fihlela mocheso o loketseng (20). °C), joale e tla qhibiliha ka ho feletseng. the

2. Omisa ho kopanya le ho kopanya:

Tabeng ea ho kopanya le li-powders tse ling, e lokela ho kopanngoa ka ho feletseng le phofo pele e eketsa metsi, ebe e ka qhibiliha ka potlako ntle le ho kopanya. the

3. Mokhoa oa ho kolobisa ka motsoako oa motsoako:

Qala ka ho qhala sehlahisoa ka har'a motsoako oa tlhaho kapa u se kolobise ka motsoako oa tlhaho, ebe u se eketsa metsing a batang ho e qhaqha hantle.
