Mabapi le bothata ba mocheso oa gel oa hydroxypropyl methylcellulose HPMC, basebelisi ba bangata ha ba ele hloko bothata ba mocheso oa gel oa hydroxypropyl methylcellulose.Matsatsing ana, hydroxypropyl methylcellulose ka kakaretso e khetholloa ho ea ka viscosity, 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.
Palo ea sehlopha sa methoxyl e amana ka kotloloho le tekanyo ea selulose sourization, 'me litaba tsa sehlopha sa methoxyl li ka fetoloa ka ho laola foromo, mocheso oa karabelo le nako ea karabelo.Ka nako e ts'oanang, tekanyo ea ho se sebetse e ama tekanyo ea ho nkela sebaka sa hydroxyethyl kapa hydroxypropyl.Ka hona, ho boloka metsi a cellulose ether e nang le mocheso o phahameng oa gel ho tla fokola.Ts'ebetso ena ea tlhahiso e hloka ho hlahlojoa, kahoo ha se hore theko ea tlhahiso ea cellulose ether e tlaase haeba methoxy content e le tlaase, ho fapana le hoo, theko e tla ba e phahameng.
Mocheso oa mocheso oa gel o khethoa ke lihlopha tsa methoxyl, 'me ho boloka metsi ho khethoa ke lihlopha tsa hydroxypropoxyl.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 ea cellulose 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 ea tšebeliso ea seretse (ntle le libaka tse khethehileng).Ha u sebelisa seretse, ha ho hlokahale hore u ele hloko ka ho khetheha index ea tshebetso ea mocheso oa gel.
