Abasebenzisi abaningi abavamile ukunaka inkinga yokushisa kwejeli ye-hydroxypropyl methylcellulose. Namuhla, i-hydroxypropyl methylcellulose ngokuvamile ihlukaniswa ngokuvumelana ne-viscosity, kodwa kwezinye izindawo ezikhethekile nezimboni ezikhethekile, i-viscosity yomkhiqizo kuphela ibonakala. Akwanele, okulandelayo kwethula kafushane izinga lokushisa lejeli le-hydroxypropyl methylcellulose.
Okuqukethwe kwe-methyl acid kuhlobene ngokuqondile ne-ester-forming degree ye-cellulose ester, futhi okuqukethwe kwe-methyl acid kulungiswa ukulawula ukwakheka, izinga lokushisa lokuphendula kanye nesikhathi sokuphendula. Ngesikhathi esifanayo, izinga lesisombululo se-ether lithinta okuqukethwe kwe-hydroxyethyl noma i-hydroxyapatite. Ngakho-ke, ama-cellulose ethers emazingeni okushisa avamile ejeli azoba manzi kancane. Le nqubo yokukhiqiza kufanele ibonakale, ngakho esikhundleni samazinga aphansi e-methoxides, ama-cellulose ethers azoba phezulu kancane ngentengo.
Izinga lokushisa lejeli lanqunywa nge-methoxide ne-hydroxyproazepam nge-hydroxyproxin. Amaqembu amathathu kuphela angashintshwa nge-cellulose. Thola izinga lokushisa elilungile, londoloza umswakama, futhi unqume iphethini ye-pulp. Izinga lokushisa lejeli liyiphuzu elibalulekile ekusetshenzisweni kwe-cellulose ether. Uma izinga lokushisa le-ambient lidlula izinga lokushisa lejeli, i-cellulose ether izokhishwa emanzini. Ukushisa kwe-pulp emakethe ngokuyinhloko ukuhlangabezana nezidingo zesixazululo emvelweni (ngaphandle kwezimo ezikhethekile). Kukholelwa ukuthi uma usebenzisa isisombululo, akudingekile ukunaka ngokukhethekile izinkomba zokusebenza uma usebenzisa ijeli. Yiqiniso, umenzi we-cellulose ether kufanele acabangele le nkomba.
