Vuto la kutentha kwa gel ya Hydroxypropyl methylcellulose

Ogwiritsa ntchito ambiri saganizira kwambiri za vuto la kutentha kwa gel kwa hydroxypropyl methylcellulose. Masiku ano, hydroxypropyl methylcellulose nthawi zambiri imasiyanitsidwa malinga ndi kukhuthala, koma m'malo ena apadera ndi mafakitale apadera, kukhuthala kwa chinthucho kokha ndiko kumaonekera. Sikokwanira, zotsatirazi zikuwonetsa mwachidule kutentha kwa gel kwa hydroxypropyl methylcellulose.

Kuchuluka kwa methyl acid kumagwirizana mwachindunji ndi kuchuluka kwa ester komwe kumapangidwa ndi cellulose ester, ndipo kuchuluka kwa methyl acid kumasinthidwa kuti kulamulire kapangidwe kake, kutentha kwa reaction ndi nthawi yochitira reaction. Nthawi yomweyo, kuchuluka kwa ether solution kumakhudza kuchuluka kwa hydroxyethyl kapena hydroxyapatite. Chifukwa chake, ma cellulose ethers pa kutentha komwe kumakhala kokwera kwa gel sadzakhala konyowa kwambiri. Njira yopangirayi iyenera kukhala yogwira mtima, kotero m'malo mwa kuchuluka kwa methoxides kochepa, ma cellulose ethers adzakhala okwera pang'ono pamtengo.

Kutentha kwa gel kunadziwika ndi methoxide ndi hydroxyproazepam ndi hydroxyproxin. Magulu atatu okha ndi omwe angalowe m'malo mwa cellulose. Pezani kutentha koyenera, sungani chinyezi, ndikuzindikira mawonekedwe a pulp. Kutentha kwa gel ndiye mfundo yofunika kwambiri pakugwiritsa ntchito cellulose ether. Kutentha kozungulira kukapitirira kutentha kwa gel, cellulose ether imatulutsidwa m'madzi. Kutentha kwa pulp pamsika makamaka kumafuna kukwaniritsa zosowa za yankho m'chilengedwe (kupatulapo zinthu zapadera). Amakhulupirira kuti mukamagwiritsa ntchito yankho, sikofunikira kuyang'ana kwambiri zizindikiro za magwiridwe antchito mukamagwiritsa ntchito gel. Zachidziwikire, wopanga cellulose ether ayenera kuganizira chizindikiro ichi.
