I-rheology kanye nokuhambisana kwezakhiwo ze-hydroxypropyl methylcellulose (HPMC) kanye ne-hydroxypropyl starch (HPS) zidlala indima ebalulekile ezimbonini ezehlukene, okuhlanganisa ezemithi, ukudla, izimonyo, nezokwakha.Ukuqonda ukusebenzisana phakathi kwalawa ma-polymer amabili kubalulekile ukuze kuthuthukiswe ukusebenza kwawo kanye nokuthuthukisa imikhiqizo emisha.Leli phepha lihlose ukuhlola izakhiwo ze-rheological kanye nokuhambisana kwe-HPMC/HPS complex.
Izici ze-Rheological:
I-Rheology isifundo sokuthi izinto ziguga futhi zigeleze kanjani ngaphansi kwethonya lamandla angaphandle.Esimeni senkimbinkimbi ye-HPMC/HPS, izakhiwo ze-rheological zinquma i-viscosity, ukuziphatha kwe-gelation, kanye nezakhiwo zokugeleza okuphelele kwenhlanganisela ye-polymer.Ukuziphatha kwe-rheological kwenkimbinkimbi kungathinteka yizici ezifana nokugxila kwe-polymer, isisindo samangqamuzana, izinga lokushisa, kanye nesilinganiso se-shear.
Ukuhambisana kwe-HPMC ne-HPS:
Ukuhambisana phakathi kwe-HPMC ne-HPS kubalulekile ukuze kuqinisekiswe ukwakheka kwezakhiwo ezizinzile ezinezakhiwo ezifiselekayo.Ukuhambisana kusho ikhono lama-polymer amabili noma ngaphezulu okuxuba nokwenza isistimu efanayo ngaphandle kokuhlukaniswa kwesigaba noma ukulahlekelwa ukusebenza.
Izici ezithinta i-rheology nokuhambisana:
Isilinganiso se-polymer: Isilinganiso se-HPMC kuya ku-HPS endaweni eyinkimbinkimbi singathinta kakhulu izakhiwo zayo ze-rheological nokuhambisana.
Isisindo samangqamuzana: Isisindo samangqamuzana se-HPMC ne-HPS sithinta i-rheology nokuhambisana kwe-complex.
Izinga lokushisa: Izinga lokushisa lapho inkimbinkimbi ilungiswa khona futhi ihlolwe ithinta ukuziphatha kwayo kwe-rheological.
I-Shear Rate: Izinga le-shear elisetshenziswa ngesikhathi sokuhlolwa noma ukucubungula lingathinta izakhiwo ze-rheological ze-HPMC/HPS complex.Amazinga aphezulu okugunda angaholela ekuziphatheni kokunciphisa i-shear, lapho i-viscosity iyancipha ngokukhuphuka kwezinga lokugunda.
Izicelo:
I-rheology nokuhambisana kwenkimbinkimbi ye-HPMC/HPS kunemiphumela ephawulekayo ezimbonini ezihlukahlukene. Ekwenziweni kwemithi, izakhiwo zingasetshenziswa ukuguqula ukukhululwa kwezidakamizwa, ukuthuthukisa ukuzinza, nokulawula i-viscosity. Ezimbonini zokudla nezimonyo, zingasetshenziswa. njenge-ejenti yokuqina, i-stabilizer, noma i-emulsifier.Ezintweni zokwakha, ama-complexes angathuthukisa ukusebenza nokunamathela kwezinhlelo zikasimende.
I-Rheology kanye nokuhambisana kwezakhiwo ze-HPMC/HPS ziyizinto ezibalulekile zokucatshangelwa ekuthuthukiseni ukusebenza kwazo ezinhlelweni ezihlukahlukene. Ukuqonda imiphumela yezinto ezifana nesilinganiso se-polymer, isisindo samangqamuzana, izinga lokushisa kanye nezinga le-shear kubalulekile ekuklameni ukwakheka okunezici ezifiselekayo ze-rheological.. Olunye ucwaningo futhi intuthuko kule ndawo ingaholela ekudalweni kwemikhiqizo emisha enokusebenza okuthuthukisiwe kanye nokusebenza okuthuthukisiwe ezimbonini eziningi.
