Ukuhlelwa kweeMveliso zeMethyl Cellulose
I-solubility yeemveliso ze-methyl cellulose (MC) inokwahluka ngokuxhomekeke kwiqondo lokutshintshwa, ubunzima be-molecular, kunye nokugxilwa kwe-MC. Ngokubanzi, iimveliso ze-MC zinyibilika emanzini abandayo, kwaye ukunyibilika kuyanda ngobushushu. Nangona kunjalo, ezinye iimveliso ze-MC ze-viscosity eziphezulu zinokufuna ixesha elide lokuchithwa okanye amaqondo obushushu aphezulu ukuze anyibilike ngokupheleleyo. Ukongeza, ezinye iimveliso ze-MC ziyilelwe ukuba zinyibilike emanzini ashushu, zizenze zibe luncedo kwizicelo ezifana nokunamathelisa anyibilikayo ashushu. Iimveliso ze-MC ezinamaqondo aphantsi okutshintshwa kunye nemilinganiselo ephantsi yeemolekyuli zivame ukuba ne-solubility ephezulu, ngelixa ezo zineedigri eziphezulu zokutshintshwa kunye nezisindo eziphezulu ze-molecular zingafuna i-solvents ezinamandla, njenge-dimethyl sulfoxide (DMSO), ukuchithwa. Kubalulekile ukubonisana nephepha ledatha yemveliso okanye imiyalelo yomenzi kwisikhokelo esithile malunga nokunyibilika kwemveliso ethile yeMC.
