Mu putty powder, imagwira ntchito zitatu zokulitsa, kusunga madzi ndi kumanga.
Kukhuthala: Ma cellulose amatha kukhuthala kuti ayimitse ndikusunga yunifolomu ya yankho mmwamba ndi pansi, ndikupewa kugwa.
Kusunga madzi: Pangani ufa wa putty kuti uume pang'onopang'ono kuti phulusa la calcium lizigwira ntchito pansi pa madzi.
Zomangamanga: Ma cellulose amakhala ndi mafuta, omwe amatha kupanga ufa wa putty kukhala womanga bwino.
Kupanga kotetezeka ndikofunikira kwambiri kuposa Phiri la Tai
HPMC satenga nawo gawo pazosintha zilizonse zamakina, koma imagwira ntchito yothandiza.Kuonjezera madzi ku ufa wa putty ndikuwuyika pakhoma ndi mankhwala, chifukwa zinthu zatsopano zimapangidwira.Tengani ufa wa putty pakhoma pakhoma, perani kukhala ufa, ndikugwiritsanso ntchito.Sizigwira ntchito chifukwa zinthu zatsopano (calcium carbonate) zapangidwa.Inde.Zigawo zazikulu za ufa wa phulusa la calcium ndi: chisakanizo cha Ca(OH2, CaO ndi CaCO3 pang'ono, CaO+H2O=Ca(OH2-Ca(OH2+CO2==CaCO3↓+H2O) Zotsatira za phulusa la calcium pa CO2 m'madzi ndi mpweya Mu chikhalidwe ichi, calcium carbonate imapangidwa, pamene HPMC imangokhala ndi madzi ndipo imathandiza kuti phulusa la calcium liziyenda bwino, ndipo silitenga nawo mbali pazochita zilizonse zokha.
Kutayika kwa ufa wa putty powder makamaka kumagwirizana ndi khalidwe la phulusa la calcium, ndipo silikugwirizana kwenikweni ndi HPMC.Kashiamu yotsika ya calcium imvi ndi chiŵerengero chosayenera cha CaO ndi Ca (OH2 mu grey calcium idzapangitsa kutaya kwa ufa.Ngati ili ndi chochita ndi HPMC, ndiye kuti kusungidwa kwa madzi kosauka kwa HPMC kudzachititsanso kutaya ufa.
