Imikhiqizo ye-cellulose ether i-HPMC ne-HEMC inawo womabili amaqembu e-hydrophobic nawe-hydrophilic.Iqembu le-methoxy liyi-hydrophobic, futhi iqembu le-hydroxypropoxy lihlukile ngokuya ngendawo yokufaka esikhundleni.Ezinye ziyi-hydrophilic kanti ezinye ziyi-hydrophobic.IHydroxyethoxy iyi-hydrophilic.Lokhu okubizwa nge-hydrophilicity kusho ukuthi inendawo yokuba seduze namanzi;i-hydrophobicity isho ukuthi inendawo yokuxosha amanzi.Njengoba umkhiqizo une-hydrophilic kanye ne-hydrophobic, umkhiqizo we-cellulose ether unomsebenzi ongaphezulu, odala amabhamuza omoya.Uma isici esisodwa kuphela kwezimbili sine-hydrophilic noma i-hydrophobic, awekho amabhamuza azokhiqizwa.Kodwa-ke, i-HEC ineqembu le-hydrophilic kuphela leqembu le-hydroxyethoxy futhi alikho iqembu le-hydrophobic, ngakho-ke ngeke likhiqize ama-bubbles.
Isenzo sebhamuza sihlobene ngqo nezinga lokuqedwa komkhiqizo.Uma umkhiqizo uncibilika ngenani elingahambisani, amabhamuza azokwakheka.Ngokuvamile, i-viscosity ephansi, izinga lokuqedwa ngokushesha.Lapho i-viscosity iphezulu, izinga lokuqedwa lihamba kancane.Esinye isizathu siyinkinga ye-granulation, i-granulation ayilingani (usayizi wezinhlayiyana awufani, kukhona ezinkulu nezincane).Ibangela ukuthi isikhathi sokuchithwa sihluke, ikhiqiza ibhamuza lomoya.
Izinzuzo zamabhamuza omoya zingandisa indawo ye-batch scraping, indawo yokwakha nayo ithuthukisiwe, i-slurry ilula, futhi i-batch scraping kulula.Ububi ukuthi ukuba khona kwamabhamuza kuzonciphisa ukuminyana kwenqwaba yomkhiqizo, kunciphise amandla, futhi kuthinte ukumelana nesimo sezulu sento.
