Lintlha tse 'maloa tse kholo tse amang ho bolokoa ha metsi a hydroxypropyl methylcellulose

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.Ke phofo e tšoeu e sa nkheng, e sa latsoeheng le e se nang chefo, e kokomohang hore e be motsoako o hlakileng kapa oa maru hanyenyane metsing a batang.E na le ho teteana, ho tlama, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, surface active, ho boloka mongobo le ho sireletsa thepa ea colloid.Hydroxypropyl methyl cellulose le methyl cellulose li ka sebelisoa ho haha, indasteri ea pente, resin ea maiketsetso, indasteri ea ceramic, meriana, lijo, masela, temo, lik'hemik'hale tsa letsatsi le letsatsi le liindasteri tse ling.

Ho boloka metsi a hydroxypropyl methylcellulose HPMC sehlahisoa ka bosona hangata ho angoa ke lintlha tse latelang:

1. Palo ea hydroxypropyl methylcellulose HPMC e ekelitsoeng Ha palo e kholo ea cellulose ether HPMC e eketsoa, ​​​​sekhahla sa ho boloka metsi se phahame le phello e ntle ea ho boloka metsi.Ho phaella ho 0.25-0.6%, tekanyo ea ho boloka metsi e eketseha ka potlako ka ho eketseha ha chelete ea ho eketsa;ha palo ea tlatsetso e ntse e eketseha, mokhoa oa ho eketseha oa sekhahla sa ho boloka metsi oa fokotseha.

2. HPMC viscosity ea hydroxypropyl methylcellulose Ha viscosity ea HPMC e eketseha, tekanyo ea ho boloka metsi e boetse e eketseha;ha viscosity e fihla boemong bo itseng, ho eketseha ha tekanyo ea ho boloka metsi ho atisa ho ba bonolo.

3. Hydroxypropyl methylcellulose HPMC mocheso oa mocheso oa gel Mocheso o phahameng oa mocheso oa mocheso, tekanyo e phahameng ea ho boloka metsi;ho seng joalo, tekanyo e tlaase ea ho boloka metsi.

4. Hydroxypropyl methylcellulose HPMC homogeneity HPMC e nang le karabelo e ts'oanang, methoxyl le hydroxypropoxyl li ajoa ka ho lekana, 'me tekanyo ea ho boloka metsi e phahame.
