Mayelana nenkinga yokushisa kwejeli yeIHydroxypropyl Methyl Cellulose HPMC, abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-Hydroxypropyl Methyl Cellulose. Namuhla, i-Hydroxypropyl Methyl Cellulose ngokuvamile ihlukaniswa ngokuvumelana ne-viscosity yayo, kodwa Kwezinye izindawo ezikhethekile nezimboni ezikhethekile, akwanele ukubonisa kuphela i-viscosity yomkhiqizo. Okulandelayo kwethula kafushane izinga lokushisa lejeli le-Hydroxypropyl Methyl Cellulose.
Inani leqembu le-Methoxyl lihlobene ngokuqondile nezinga le-cellulose sourization, futhi okuqukethwe kweqembu le-Methoxyl kungalungiswa ngokulawula ifomula, izinga lokushisa lokuphendula kanye nesikhathi sokuphendula. Ngesikhathi esifanayo, izinga lokungasebenzi lithinta izinga lokushintshwa kwe-Hydroxyethyl noma i-Hydroxypropyl. Ngakho-ke, ukugcinwa kwamanzi kwe-cellulose ether enezinga lokushisa eliphezulu lejeli kuyoba kubi. Le nqubo yokukhiqiza idinga ukuhlolwa, ngakho-ke akukhona ukuthi izindleko zokukhiqiza ze-cellulose ether ziphansi uma okuqukethwe kwe-Methoxy kuphansi, ngokuphambene nalokho, intengo izoba phezulu.
Izinga lokushisa lejeli linqunywa amaqembu e-methoxyl, futhi ukugcinwa kwamanzi kunqunywa amaqembu e-Hydroxypropoxy. Kunamaqembu amathathu kuphela angathatha indawo ku-cellulose. Thola izinga lokushisa elifanele lokusetshenziswa kwakho, ukugcinwa kwamanzi okufanele, bese unquma imodeli yale cellulose.
Izinga lokushisa lejeli liyiphuzu elibalulekile ekusetshenzisweni kwei-cellulose ether. Uma izinga lokushisa le-ambient lidlula izinga lokushisa lejeli, i-cellulose ether izohlukaniswa emanzini futhi ilahlekelwe ukugcinwa kwayo kwamanzi. Izinga lokushisa lejeli le-cellulose ether emakethe lingahlangabezana nezidingo zendawo yokusetshenziswa kodaka (ngaphandle kwezindawo ezikhethekile). Mina ngokwami ngicabanga ukuthi akudingekile ukunaka ngokukhethekile inkomba yokusebenza yokushisa kwe-gel lapho usebenzisa udaka. Yiqiniso, ukukhiqizwa kwe-cellulose ether Abakhiqizi kumele bakucabangele.
