Abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-hydroxypropyl methylcellulose. Namuhla, i-hydroxypropyl methylcellulose ngokuvamile ihlukaniswa ngokwe-viscosity, kodwa kwezinye izindawo ezikhethekile kanye nezimboni ezikhethekile, i-viscosity yomkhiqizo kuphela ebonakala. Akwanele, okulandelayo kwethula kafushane izinga lokushisa kwejeli ye-hydroxypropyl methylcellulose.
Okuqukethwe kwe-methyl acid kuhlobene ngqo nezinga lokwakha i-ester le-cellulose ester, futhi okuqukethwe kwe-methyl acid kulungiswa ukulawula ukwakheka, izinga lokushisa lokusabela kanye nesikhathi sokusabela. Ngesikhathi esifanayo, izinga lesisombululo se-ether lithinta okuqukethwe kwe-hydroxyethyl noma i-hydroxyapatite. Ngakho-ke, ama-cellulose ethers emazingeni okushisa avame ukuphakama ejeli ngeke abe manzi kangako. Le nqubo yokukhiqiza kufanele ibonakale, ngakho esikhundleni samazinga aphansi e-methoxides, ama-cellulose ethers azoba phezulu kancane ngentengo.
Izinga lokushisa lejeli linqunywe nge-methoxide kanye ne-hydroxyproazepam nge-hydroxyproxin. Amaqembu amathathu kuphela angashintshwa ku-cellulose. Thola izinga lokushisa elifanele, wonge umswakama, bese unquma iphethini ye-pulp. Izinga lokushisa lejeli liyiphuzu elibalulekile lokusetshenziswa kwe-cellulose ether. Lapho izinga lokushisa elizungezile lidlula izinga lokushisa lejeli, i-cellulose ether izokhishwa emanzini. Izinga lokushisa le-pulp emakethe ngokuyinhloko lihloselwe ukuhlangabezana nezidingo zesisombululo endaweni ezungezile (ngaphandle kwezimo ezikhethekile). Kukholelwa ukuthi lapho kusetshenziswa ikhambi, akudingekile ukunaka ngokukhethekile izinkomba zokusebenza lapho kusetshenziswa ijeli. Vele, umenzi we-cellulose ether kufanele acabangele lesi sibonakaliso.
