IHydroxypropyl Methyl Cellulose (HPMC) iyi-polymer evamile esetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa ezemithi, ukudla, kanye nezokwakha.Uma usebenzisa i-HPMC, kubalulekile ukuyincibilikisa ngendlela efanele ukuze uqinisekise ukuthi ixubana ngokulinganayo futhi ayenzi izigaxa.Nazi ezinye izindlela eziqondile zokuncibilikisa i-HPMC:
Ukulungiselela Isixazululo: Isinyathelo sokuqala ukulungisa isixazululo se-HPMC.Ukugxila kwesixazululo kuzoncika kuhlelo lokusebenza, kodwa ngokuvamile kuhluka kusuka ku-0.5% kuya ku-5%.Qala ngokwengeza inani elidingekayo le-HPMC esitsheni esifanele.
Ukwengeza Amanzi: Isinyathelo esilandelayo ukufaka amanzi esitsheni.Kubalulekile ukusebenzisa amanzi acwengekile noma akhishiwe ukuze kuqinisekiswe ukuthi akukho ukungcola okungathinta izakhiwo ze-HPMC.Amanzi kufanele engezwe kancane ngenkathi ushukumisa ingxube ukuqinisekisa ukuthi i-HPMC incibilika ngokulinganayo.
Ukuxuba Isixazululo: Uma amanzi kanye ne-HPMC seyengeziwe, ingxube kufanele inyakaze noma inyakaze ngokuqhubekayo kuze kube yilapho i-HPMC isihlakazwe ngokuphelele.Kunconywa ukusebenzisa i-mixer mechanical noma i-homogenizer ukuqinisekisa ukuqedwa okuphelele.
Ukuvumela Isixazululo Ukuphumula: Uma i-HPMC isihlakazwe ngokuphelele, kunconywa ukuvumela isisombululo ukuthi siphumule amahora ambalwa.Lesi sikhathi sokuphumula sivumela noma yimaphi amabhamuza omoya ukuthi abaleke futhi siqinisekisa ukuthi isisombululo siyafana.
Ukuhlunga Isixazululo: Isinyathelo sokugcina ukuhlunga isixazululo ukususa noma yikuphi ukungcola noma izinhlayiya ezingancibilikisiwe.Lesi sinyathelo sibaluleke kakhulu ekusetshenzisweni kwemithi nokudla, lapho ukuhlanzeka kubaluleke kakhulu.Isihlungi esinosayizi wembotshana ongu-0.45 μm noma ngaphansi ngokuvamile sisetshenziswa.
Kafushane, ukuhlakaza i-HPMC ngendlela efanele, udinga ukulungisa isisombululo, wengeze amanzi kancane kancane ngenkathi uvuselela, hlanganisa isisombululo kuze kube yilapho i-HPMC ichitheka ngokuphelele, vumela isisombululo siphumule, futhi uhlunge isisombululo ukuze ususe noma yikuphi ukungcola noma izinhlayiya ezingancibilikisiwe.
