Mayelana nenkinga yokushisa kwejeli ye-hydroxypropyl methylcellulose HPMC, abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-hydroxypropyl methylcellulose.Namuhla, i-hydroxypropyl methylcellulose ngokuvamile ihlukaniswa ngokuya nge-viscosity, kodwa Kwezinye izindawo ezikhethekile nezimboni ezikhethekile, akwanele ukubonisa kuphela i-viscosity yomkhiqizo.Okulandelayo kwethula kafushane izinga lokushisa lejeli le-hydroxypropyl methylcellulose.
Inani leqembu le-methoxyl lihlobene ngokuqondile nezinga le-cellulose sourization, futhi okuqukethwe kweqembu le-methoxyl kungalungiswa ngokulawula ifomula, izinga lokushisa lokusabela 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-hydroxypropoxyl.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 kwe-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).Uma usebenzisa udaka, asikho isidingo sokunaka ngokukhethekile inkomba yokusebenza yokushisa kwe-gel.
