Bokhoni ba ho boloka metsi ba hydroxypropyl methylcellulose bo ipapisitse le litaba tsa hydroxypropyl. Tlas'a maemo a tšoanang, matla a ho boloka metsi a phahameng a hydroxypropyl methylcellulose a matla, 'me methoxy content ea hydroxypropyl content e fokotsehile ka mokhoa o nepahetseng. . Ha litaba tsa hydroxypropyl methylcellulose li phahame, li na le viscosity e kholo, kahoo ha u khetha sehlahisoa, u tlameha ho khetha sehlahisoa se u tšoanelang ho ea ka morero oa sehlahisoa.
Mocheso le lintlha tse ling li na le phello ea ho boloka metsi a hydroxypropyl methylcellulose.
Mocheso oa mocheso oa gel:
Cellulose ether HPMC e na le mocheso o phahameng oa mocheso oa mocheso le ho boloka metsi hantle; ho fapana le hoo, e na le phallo e mpe ea metsi.
Viscosity ea cellulose ether HPMC:
Ha viscosity ea HPMC e eketseha, ho boloka metsi a eona ho boetse ho eketseha; ha viscosity e eketseha ho isa tekanyong e itseng, ho eketseha ha metsi ho fokotseha.
Cellulose ether HPMC homogeneous:
HPMC e na le karabelo e tšoanang, kabo e tšoanang ea methoxyl le hydroxypropoxyl, 'me e na le ho boloka metsi hantle.
Cellulose ether HPMC litekanyetso li behoa:
Ha litekanyetso li ntse li eketseha, sekhahla sa ho boloka metsi se phahame le phello e hlakileng haholoanyane ea ho boloka metsi.
Ha chelete ea tlatsetso e le 0.25 ~ 0.6%, sekhahla sa ho boloka metsi se eketseha ka potlako ka keketseho ea chelete ea tlatsetso; ha palo ea tlatsetso e eketseha ho feta, mokhoa oa ho eketseha oa sekhahla sa ho boloka metsi oa fokotseha.
Ka bokhutšoanyane, ho boloka metsi ha HPMC ho amana le lintlha tse kang mocheso le viscosity, 'me ho boloka metsi ho amana le palo ea hydroxypropyl methylcellulose e kenyelitsoeng. Ha palo ea hydroxypropyl methylcellulose e fihla boleng bo itseng, ts'ebetso ea eona ea ho boloka metsi e fihla ho leka-lekana.
