IHydroxypropyl Methyl Cellulose (HPMC) yipolymer eqhelekileyo esetyenziswa kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya kunye nokwakha.Xa usebenzisa i-HPMC, kubalulekile ukuyinyibilikisa ngokuchanekileyo ukuqinisekisa ukuba ixube ngokulinganayo kwaye ayenzi amaqhuqhuva.Nazi iindlela ezithile zokunyibilikisa i-HPMC:
Ukulungiselela Isisombululo: Inyathelo lokuqala kukulungiselela isisombululo se-HPMC.Ukugxininiswa kwesisombululo kuya kuxhomekeka kwisicelo, kodwa ngokuqhelekileyo kuvela kwi-0.5% ukuya kwi-5%.Qala ngokudibanisa isixa esifunekayo se-HPMC kwisikhongozeli esifanelekileyo.
Ukongeza Amanzi: Inyathelo elilandelayo kukongeza amanzi kwisikhongozeli.Kubalulekile ukusebenzisa amanzi anedistilled okanye deionized ukuqinisekisa ukuba akukho ukungcola okunokuchaphazela iimpawu ze-HPMC.Amanzi kufuneka afakwe ngokucothayo ngelixa uvuselela umxube ukuqinisekisa ukuba i-HPMC inyibilika ngokulinganayo.
Ukuxuba Isisombululo: Emva kokuba amanzi kunye ne-HPMC zongezwa, umxube kufuneka uvuselelwe okanye uphazamiseke ngokuqhubekayo de i-HPMC ichithwe ngokupheleleyo.Kunconywa ukusebenzisa umxube womatshini okanye i-homogenizer ukuqinisekisa ukuchithwa okupheleleyo.
Ukuvumela Isisombululo Ukuphumla: Emva kokuba i-HPMC ichithwe ngokupheleleyo, kuyacetyiswa ukuba kuvunyelwe isisombululo ukuba siphumle iiyure ezimbalwa.Eli xesha lokuphumla livumela nawaphi na amaqamza omoya ukuba abaleke kwaye aqinisekise ukuba isisombululo siyafana.
Ukucoca Isisombululo: Isinyathelo sokugqibela kukucoca isisombululo sokususa nayiphi na into engcolileyo okanye iincinci ezinganyibilikiyo.Eli nyathelo libaluleke kakhulu kwizicelo zamachiza kunye nokutya, apho ubunyulu bubaluleke kakhulu.Isihluzo esinobungakanani bepore eyi-0.45 μm okanye encinci siqhele ukusetyenziswa.
Isishwankathelo, ukunyibilikisa i-HPMC ngokuchanekileyo, kufuneka ulungiselele isisombululo, udibanise amanzi ngokucothayo ngelixa uvuselela, xuba isisombululo de i-HPMC ichithwe ngokupheleleyo, vumela isisombululo ukuba siphumle, kwaye sihluze isisombululo sokususa nakuphi na ukungcola okanye amaqhekeza anganyibilikiyo.
