Mabapi le mocheso oa gel oa hydroxypropyl methyl celluloseHPMC, basebelisi ba bangata ha ba ele hloko mocheso oa gel oa hydroxypropyl methyl cellulose. Hona joale hydroxypropyl methyl cellulose ka kakaretso e khetholloa ho ea ka viscosity ea eona, empa bakeng sa libaka tse ling tse khethehileng le liindasteri tse khethehileng, ha hoa lekana ho bonahatsa viscosity ea sehlahisoa feela. Se latelang se hlahisa ka bokhuts'oane mocheso oa gel oa hydroxypropyl methylcellulose.
Likahare tsa lihlopha tsa methoxy li amana ka ho toba le tekanyo ea dialysis ea cellulose, 'me litaba tsa lihlopha tsa methoxy li ka fetoloa ka ho laola foromo, mocheso oa karabelo le nako ea ho itšoara. Ka nako e ts'oanang, tekanyo ea carboxylation e ama tekanyo ea phetisetso ea hydroxyethyl kapa hydroxypropyl. Ka hona, ho boloka metsi a cellulose ethers ka mocheso o phahameng oa gel hangata ho mpefala hanyane. Ts'ebetso ena ea tlhahiso e hloka ho hlahlojoa, kahoo ha se hore litaba tsa sehlopha sa methoxy li tlaase, theko ea tlhahiso ea cellulose ether e tlaase, ho fapana le hoo, theko ea eona e tla ba e phahameng.
Mocheso oa mocheso oa gel o khethoa ke sehlopha sa methoxy, 'me ho boloka metsi ho khethoa ke sehlopha sa hydroxypropoxy. Ho na le lihlopha tse tharo feela tse nkeloang sebaka ka selulose. Fumana mocheso oa hau o loketseng oa ts'ebeliso, ho boloka metsi a loketseng, ebe u khetha mofuta oa selulose ena.
Mocheso oa mocheso oa gel ke ntlha ea bohlokoa bakeng sa ts'ebeliso eacellulose ether. Ha mocheso oa tikoloho o feta mocheso oa gel, cellulose ether e tla arohana le metsi 'me e lahleheloe ke ho boloka metsi. Mocheso oa mocheso oa gel oa cellulose ether 'marakeng o ka finyella litlhoko tsa tikoloho eo seretse se sebelisoang ho eona (ntle le libaka tse khethehileng). Bahlahisi ba tlameha ho ela sena hloko.
