Kwi-putty powder, idlala indima ezintathu zokwandisa ukuqina, ukugcina amanzi kunye nokwakha.
Ukuqina: I-Cellulose ingenziwa ibe nkulu ukuze ixhonywe kwaye igcine isisombululo sihambelana phezulu nasezantsi, kwaye singavumeli ukugoba.
Ukugcinwa kwamanzi: Yenza umgubo we-putty wome kancinci ukuze uncede i-ash calcium ukuba isabele phantsi kwentshukumo yamanzi.
Ulwakhiwo: I-Cellulose inefuthe lokuthambisa, nto leyo enokwenza ukuba umgubo we-putty ube nolwakhiwo oluhle.
Imveliso ekhuselekileyo ibaluleke ngakumbi kuneNtaba iTai
I-HPMC ayithathi nxaxheba kuzo naziphi na ii-chemical reactions, kodwa idlala indima yokuncedisa kuphela. Ukongeza amanzi kumgubo we-putty uze uwubeke eludongeni yindlela yokusabela kwamakhemikhali, kuba izinto ezintsha ziyavela. Susa umgubo we-putty eludongeni, uwugaye ube ngumgubo, uze uyisebenzise kwakhona. Ayizukusebenza kuba izinto ezintsha (i-calcium carbonate) zenziwe. Ewe. Izinto eziphambili ze-ash calcium powder zezi: umxube we-Ca(OH2, CaO kunye ne-CaCO3 encinci, i-CaO+H2O=Ca(OH2-Ca(OH2+CO2==CaCO3↓+H2O Isiphumo se-ash calcium kwi-CO2 emanzini nasemoyeni. Phantsi kwale meko, i-calcium carbonate iveliswa, ngelixa i-HPMC igcina amanzi kuphela kwaye inceda indlela engcono yokusabela kwe-ash calcium, kwaye ayithathi nxaxheba kuyo nayiphi na indlela yokusabela.
Ukulahleka komgubo we-putty powder kuxhomekeke kakhulu kumgangatho we-ash calcium, kwaye akunanto yakwenza ne-HPMC. Umthamo we-calcium ophantsi we-gray calcium kunye nomlinganiselo ongafanelekanga we-CaO kunye ne-Ca(OH2 kwi-gray calcium kuya kubangela ukulahleka komgubo. Ukuba inento yokwenza ne-HPMC, ngoko ukugcinwa kwamanzi okungalunganga kwe-HPMC kuya kubangela ukulahleka komgubo.
