Abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-hydroxypropyl methyl cellulose HPMC. Namuhla, i-hydroxypropyl methyl cellulose HPMC ngokuvamile ihlukaniswa nge-viscosity, kodwa kwezinye izindawo ezikhethekile kanye nezimboni ezikhethekile, i-viscosity yomkhiqizo kuphela ebonakala. Akwanele, okulandelayo kwethula kafushane izinga lokushisa kwejeli ye-hydroxypropyl methylcellulose HPMC.
Okuqukethwe kweqembu le-methoxy kuhlobene ngqo nezinga lokushintshwa kwe-cellulose ether. Okuqukethwe kweqembu le-methoxy kungalungiswa ngokulawula ifomula, izinga lokushisa lokusabela kanye nesikhathi sokusabela. Ngesikhathi esifanayo, izinga lokushintshwa kwe-ether lithinta izinga lokufakwa esikhundleni kwe-hydroxyethyl noma i-hydroxypropyl. Ngakho-ke, ukugcinwa kwamanzi kwe-cellulose ether enokushisa okuphezulu kwejeli ngokuvamile kubi kancane. Le nqubo yokukhiqiza kufanele ihlolwe, ngakho-ke akungenxa yokuthi okuqukethwe kwe-methoxy kuphansi, intengo ye-cellulose ether iphansi, ngokuphambene nalokho, intengo izoba phezulu.
Okuqukethwe kwe-hydroxypropyl methyl cellulose HPMC hydroxypropyl ye-QUALICELL kungu-25%. Izinga lokushisa lejeli liyiphuzu elibalulekile ekusetshenzisweni kwe-cellulose ether. Lapho izinga lokushisa elizungezile lidlula izinga lokushisa lejeli, i-cellulose ether izophuma emanzini futhi ilahlekelwe ukugcinwa kwamanzi. Izinga lokushisa lejeli le-cellulose ether le-Qualicell lingama-degrees angu-65, okungahlangabezana nezidingo zendawo yokusetshenziswa kwe-mortar kanye ne-putty (ngaphandle kwezindawo ezikhethekile). Uma uthenga i-QualiCell HPMC, sicela wazise kusenesikhathi uma unezidingo ezikhethekile.
