Ogwiritsa ntchito ambiri salabadira vuto la kutentha kwa gel osakaniza a hydroxypropyl methylcellulose. Masiku ano, hydroxypropyl methylcellulose nthawi zambiri amasiyanitsidwa ndi mamasukidwe akayendedwe, koma m'malo ena apadera komanso mafakitale apadera, kukhuthala kokha kwa mankhwalawa kumawonekera. Zosakwanira, zotsatirazi zikuwonetsa mwachidule kutentha kwa gel wa hydroxypropyl methylcellulose.
Zomwe zili mu methyl acid zimagwirizana mwachindunji ndi ester-forming degree of cellulose ester, ndipo zomwe zili mu methyl acid zimasinthidwa kuti zithetse kupanga, kutentha kwa kutentha ndi nthawi yochitira. Pa nthawi yomweyo, mlingo wa efa njira zimakhudza zili hydroxyethyl kapena hydroxyapatite. Choncho, ma cellulose ethers pa kutentha komwe kumakhala kokwera kwambiri kwa gel osakaniza sakhala onyowa kwambiri. Njira yopangira izi iyenera kukhala yogwirika, kotero mmalo mwa milingo yotsika ya methoxides, ma cellulose ethers adzakhala okwera pang'ono pamtengo.
Kutentha kwa gel osakaniza kunatsimikiziridwa ndi methoxide ndi hydroxyproazepam ndi hydroxyproxin. Magulu atatu okha angalowe m'malo mwa cellulose. Pezani kutentha koyenera, sungani chinyezi, ndi kudziwa zamkati. Kutentha kwa gel ndi chinthu chofunikira kwambiri pakugwiritsa ntchito cellulose ether. Pamene kutentha kozungulira kumadutsa kutentha kwa gel, cellulose ether imatulutsidwa m'madzi. Kutentha kwa zamkati pamsika makamaka kukwaniritsa zosowa za yankho mu chilengedwe (kupatulapo zinthu zapadera). Amakhulupirira kuti pogwiritsira ntchito yankho, sikoyenera kumvetsera mwapadera zizindikiro za ntchito pogwiritsa ntchito gel osakaniza. Inde, wopanga cellulose ether ayenera kuganizira chizindikiro ichi.
