Ku-putty powder, idlala indima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakhiwa.
Ukuqina: I-Cellulose ingaqiniswa ukuze imiswe futhi igcine isisombululo silingana phezulu naphansi, futhi simelane nokuwa.
Ukugcinwa kwamanzi: Yenza i-putty powder yome kancane ukuze kusize i-calcium yomlotha ukuthi isabele ngaphansi kokusebenza kwamanzi.
Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokwakhiwa okuhle.
Ukukhiqizwa okuphephile kubaluleke kakhulu kuneNtaba iTai
I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusiza kuphela. Ukwengeza amanzi ku-putty powder nokuyifaka odongeni kuyindlela yokusabela kwamakhemikhali, ngoba izinto ezintsha ziyakhiwa. Khipha i-putty powder odongeni, uyigaye ibe yi-powder, bese uyisebenzisa futhi. Ngeke isebenze ngoba izinto ezintsha (i-calcium carbonate) sezivele zakhiwe. Yebo. Izingxenye eziyinhloko ze-ash calcium powder yilezi: ingxube ye-Ca(OH2, CaO kanye nenani elincane le-CaCO3, CaO+H2O=Ca(OH2-Ca(OH2+CO2==CaCO3↓+H2O Umphumela we-ash calcium ku-CO2 emanzini nasemoyeni Ngaphansi kwalesi simo, kukhiqizwa i-calcium carbonate, kuyilapho i-HPMC igcina amanzi kuphela futhi isiza ukusabela okungcono kwe-ash calcium, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwayo.
Ukulahleka kwempuphu yempuphu ye-putty kuhlobene kakhulu nekhwalithi ye-calcium yomlotha, futhi akuhlobene kakhulu ne-HPMC. Okuqukethwe kwe-calcium ephansi ye-calcium empunga kanye nesilinganiso esingafanele se-CaO kanye ne-Ca(OH2 ku-calcium empunga kuzobangela ukulahleka kwempuphu. Uma kuhlobene ne-HPMC, khona-ke ukugcinwa kwamanzi okungekuhle kwe-HPMC nakho kuzobangela ukulahleka kwempuphu.
