Iimveliso ze-cellulose ether ze-HPMC kunye ne-HEMC zinamaqela amabini e-hydrophobic kunye ne-hydrophilic.Iqela le-methoxy li-hydrophobic, kwaye iqela le-hydroxypropoxy lihluke ngokuhambelana nendawo yokutshintsha.Ezinye ziyi-hydrophilic kwaye ezinye ziyi-hydrophobic.IHydroxyethoxy yi-hydrophilic.Into ebizwa ngokuba yi-hydrophilicity ithetha ukuba inepropati yokuba kufuphi namanzi;i-hydrophobicity ithetha ukuba inepropati yokugxotha amanzi.Ekubeni imveliso i-hydrophilic kunye ne-hydrophobic, imveliso ye-cellulose ether inomsebenzi ongaphezulu, odala amaqamza omoya.Ukuba enye kuphela kwiipropati ezimbini i-hydrophilic okanye i-hydrophobic, akukho maqamza aya kuveliswa.Nangona kunjalo, i-HEC ineqela le-hydrophilic kuphela yeqela le-hydroxyethoxy kwaye ayinalo iqela le-hydrophobic, ngoko ayiyi kuvelisa ama-bubbles.
I-bubble phenomenon nayo ihambelana ngokuthe ngqo kwizinga lokuchithwa kwemveliso.Ukuba imveliso inyibilika ngesantya esingahambelaniyo, amaqamu aya kubumba.Ngokuqhelekileyo, i-viscosity ephantsi, ngokukhawuleza isantya sokuchithwa.Ukuphakama kwe-viscosity, isantya sokupheliswa sicotha.Esinye isizathu yinkinga ye-granulation, i-granulation ayilingani (ubukhulu be-particle ayifani, kukho ezinkulu kunye ezincinci).Ibangela ukuba ixesha lokuchithwa lihluke, livelise iqamza lomoya.
Izibonelelo zeebhubhu zomoya zinokunyusa indawo ye-batch scraping, ipropati yokwakha nayo iphuculwe, i-slurry ilula, kwaye i-batch scraping ilula.Ukungalungi kukuba ubukho bamaqamza buya kunciphisa ubuninzi bemveliso, ukunciphisa amandla, kunye nokuchaphazela ukuchasana kwemozulu yezinto.
