Ukugcinwa kwamanzi kuyisilinganiso sokusetshenziswa kabusha kwe-HPMC hydroxypropyl methylcellulose, ukugcinwa kwamanzi kokuhle nokubi nakho kuthintwa abakhiqizi abaningi basekhaya bodaka olomile, ikakhulukazi izinga lokushisa eliphezulu lokushisa lokunakwa kwefekthri eseningizimu, ngasikhathi sinye, bekunezizathu eziningi ezithinta imiphumela. amanzi odaka oluyimpuphu eyomile, njengokwengeza ivolumu, i-viscosity, ubuncane bezinhlayiyana kanye nokusetshenziswa kwemvelo, izinga lokushisa, njll.
Enqubeni yodaka oluxutshwe ngaphambili oluxutshwe okomile, inani elingeziwe le-hydroxypropyl methyl cellulose liphansi.Nakuba inani elingeziwe liphansi, ngokusobala lingathuthukisa ukusebenza kodaka olumanzi, okubuye kube isengezo esiyinhloko esithinta ukusebenza kokwakhiwa kodaka.Ngakho-ke, ukukhethwa kwesayensi nokunengqondo kwe-cellulose ether enemikhiqizo ehlukene, i-viscosity ehlukene, ukucoleka kwezinhlayiyana ezihlukene kanye nenani lokwengeza kunethonya elikhulu ekuthuthukisweni kokusebenza kodaka oluxubekile oluxubile.
Ngokwendawo yokwakha yamanje, ukusebenza kwamanzi amaningi okwakha amatshe nodaka akulungile, indawo ethule imizuzu embalwa ingaba ukuhlukaniswa kodaka lwamanzi, futhi ukugcinwa kwamanzi kuyi-hydroxypropyl methylcellulose ether indima enkulu, i-cellulose ether encibilika emanzini. Udaka oluxubekile lunendima ebaluleke kakhulu, indima yendawo eyinhloko inezintathu, eyodwa, Ukusebenza kahle kokugcinwa kwamanzi, okwesibili, ithonya lokungaguquguquki kanye ne-thixotropy yodaka oluxutshwe ngomumo, okwesithathu, ithonya lokusebenzisana nosimende. .Ukusebenza kokugcina amanzi kwe-Hydroxypropyl methylcellulose kuncike kakhulu esisekelweni sokumuncwa kwamanzi, ukwakheka kodaka, ugqinsi lwengqimba yodaka, kanye nezidingo zamanzi odaka, kanye nesikhathi sokufiphala sento yokufingqa, yokugcina amanzi e-cellulose ether, ikakhulukazi kusukela ekuncibilikeni kwemvelo kanye nokuphelelwa amandla kwamanzi. i-celluloseether.
I-Hydroxypropyl methylcellulose idlala indima ebalulekile enqubweni yodaka oluxubekile oluxubekile omile, olungadlala indima ekugcineni amanzi, ukuqina, ukubambezeleka kwamandla kasimende, futhi kungathuthukisa ukusebenza kokwakhiwa.Ukusebenza kahle kokugcinwa kwamanzi kungenza usimende hydration iphelele, kungathuthukisa i-viscosity emanzi yodaka olumanzi, ukuze kuthuthukiswe amandla okubopha odaka, kodwa futhi kungalungisa isikhathi.Ukwengeza i-hydroxypropyl methylcellulose ether enkambweni yodaka olomile oluxubile oluxubekile kungathuthukisa ukusebenza kokwakhiwa kodaka, kungathuthukisa amandla esakhiwo, ukuze kusetshenziswe kabanzi emkhakheni wokufaka udaka.
