Abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-hydroxypropyl methyl cellulose HPMC.Namuhla, i-hydroxypropyl methyl cellulose HPMC ngokuvamile ihlukaniswa yi-viscosity, kodwa kwezinye izindawo ezikhethekile nezimboni ezikhethekile, i-viscosity yomkhiqizo kuphela ibonakala.Akwanele, okulandelayo kwethula kafushane izinga lokushisa lejeli le-hydroxypropyl methylcellulose HPMC.
Okuqukethwe kweqembu le-methoxy kuhlobene ngokuqondile nezinga le-etherification ye-cellulose ether.Okuqukethwe kweqembu le-methoxy kungalungiswa ngokulawula ifomula, izinga lokushisa lokuphendula kanye nesikhathi sokuphendula.Ngesikhathi esifanayo, izinga le-etherification lithinta izinga lokushintshwa kwe-hydroxyethyl noma i-hydroxypropyl.Ngakho-ke, ukugcinwa kwamanzi kwe-cellulose ether enezinga lokushisa eliphezulu lejeli ngokuvamile kuba kubi kancane.Le nqubo yokukhiqiza kufanele ihlolwe, ngakho-ke akukhona ukuthi okuqukethwe kwe-methoxy kuphansi, intengo ye-cellulose ether iphansi, ngokuphambene nalokho, intengo izoba phezulu.
Okuqukethwe kwe-QUALICELL's hydroxypropyl methyl cellulose HPMC hydroxypropyl kungu-25%.Izinga lokushisa lejeli liyiphuzu elibalulekile ekusetshenzisweni kwe-cellulose ether.Uma izinga lokushisa le-ambient lidlula izinga lokushisa lejeli, i-cellulose ether izophuma emanzini futhi ilahlekelwe ukugcinwa kwayo kwamanzi.Izinga lokushisa lejeli ye-cellulose ether ye-Qualicell ingama-degrees angu-65, elingahlangabezana nezidingo zendawo yokusebenzisa udaka kanye ne-putty (ngaphandle kwezindawo ezikhethekile).Uma uthenga i-QualiCell HPMC, sicela wazise kusengaphambili uma unezidingo ezikhethekile.
