Isilinganiso esinembile sokuqukethwe komlotha sibalulekile ezimbonini ezihlukahlukene ezisebenzisa i-cellulose njengento eluhlaza.Ukunquma okuqukethwe komlotha kunikeza ulwazi olubalulekile mayelana nokuhlanzeka kanye nekhwalithi ye-cellulose, kanye nokufaneleka kwayo kwezinhlelo zokusebenza ezithile.Kulesi sihloko, sizohlola inqubo yesinyathelo ngesinyathelo yokulinganisa ngokunembile okuqukethwe komlotha we-cellulose.
Ukulungiselela Isampula:
Ukuze uqale, thola isampula elimele i-cellulose ukuze lihlaziywe.Qinisekisa ukuthi isampuli iyafana futhi ayinakho ukungcola okungase kuthinte isilinganiso.Kunconywa ukusebenzisa usayizi wesampula omkhulu owanele ukuze uphendule nganoma yikuphi ukungahambisani kokubalulekile.
Ukukala Ngaphambilini:
Usebenzisa ibhalansi yokuhlaziya ngokunemba okuphezulu, kala isitsha se-crucible esingenalutho nesihlanzekile noma se-porcelain.Qopha isisindo ngokunembile.Lesi sinyathelo sisungula isisindo se-tare futhi sivumela ukunqunywa kokuqukethwe komlotha kamuva.
Ukukala Isampula:
Dlulisa ngokucophelela isisindo esaziwayo sesampula ye-cellulose esitsheni esikalwe kusengaphambili se-crucible noma se-porcelain.Futhi, sebenzisa ibhalansi yokuhlaziya ukuze unqume isisindo sesampula ngokunembile.Rekhoda isisindo sesampula ye-cellulose.
Inqubo ye-Ashing:
Beka i-crucible elayishiwe noma isitsha esiqukethe isampula ye-cellulose esithandweni somlilo.Isithando somlilo se-muffle kufanele sishiswe ngaphambili ukuze sibe nezinga lokushisa elifanele, ngokuvamile eliphakathi kuka-500 kuya ku-600 degrees Celsius.Qinisekisa ukuthi izinga lokushisa liyagcinwa kuyo yonke inqubo yomlotha.
Ubude besikhathi somlotha:
Vumela isampula ye-cellulose ukuthi ishiswe ngokuphelele noma i-oxidation esithandweni se-muffle ubude besikhathi esinqunywe kusengaphambili.Isikhathi somlotha singahluka kuye ngohlobo nokwakheka kwesampula ye-cellulose.Ngokuvamile, inqubo yokuwasha ithatha amahora amaningana.
Ukupholisa kanye Nokususwa:
Uma umlotha usuqedile, susa i-crucible noma isitsha esithandweni somlilo usebenzisa izindlawu bese usibeka endaweni ekwazi ukumelana nokushisa ukuze uphole.Ngemuva kokupholisa, dlulisela i-crucible ku-desiccator ukuvimbela ukumuncwa komswakama.Vumela i-crucible ukuthi iphole ekamelweni lokushisa ngaphambi kokukala.
Ngemuva Kwesisindo:
Usebenzisa ibhalansi efanayo yokuhlaziya, kala i-crucible equkethe insalela yomlotha.Qinisekisa ukuthi i-crucible ihlanzekile futhi ayinazo izinhlayiya zomlotha ezivulekile.Rekhoda isisindo se-crucible nensalela yomlotha.
Ukubala:
Ukuze unqume okuqukethwe komlotha, susa isisindo se-crucible engenalutho (isisindo se-tare) esisindweni se-crucible nensalela yomlotha.Hlukanisa isisindo esitholiwe ngesisindo sesampula ye-cellulose bese uphindaphinda ngo-100 ukuveza okuqukethwe komlotha njengephesenti.
Okuqukethwe Umlotha (%) = [(Isisindo Se-Crucible + Insalela Yomlotha) - (Isisindo Se-Tare)] / (Isisindo Sesampula Seselulosi) × 100
Ukulinganisa ngokunembile okuqukethwe komlotha we-cellulose kubalulekile ekuhloleni ikhwalithi yayo nokufaneleka kwezinhlelo zokusebenza ezihlukahlukene.Ngokulandela inqubo yesinyathelo ngesinyathelo echazwe kulesi sihloko, umuntu angathola imiphumela ethembekile nenembayo.Kubalulekile ukugcina ukulawula ngokucophelela inqubo yokukala, izinga lokushisa, kanye nesikhathi somlotha ukuze kuqinisekiswe izilinganiso ezinembile.Ukulinganiswa okuvamile nokuqinisekiswa kwemishini nakho kubalulekile ukuze kuqinisekiswe ukwethembeka kokuhlaziywa.
