IHydroxypropyl Methyl Cellulose (HPMC) yipolima 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: Xa amanzi kunye ne-HPMC zongezwa, umxube kufuneka ushukunyiswe 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, udibanise isisombululo de i-HPMC ichithwe ngokupheleleyo, vumela isisombululo ukuba siphumle, kwaye sihluze isisombululo sokususa naluphi na ukungcola okanye amaqhekeza anganyibilikiyo.
