Ukuminyana kweGlycerol: Ukuhlaziywa Okuphelele
I-Glycerol (glycerine) iyikhemikhali esetshenziswa ezimbonini eziningi, kusukela kwezimonyo kuya ekugayweni kokudla kuye kwezimboni zemithi namakhemikhali. Kulesi sihloko, sizobhekisisa ukuminyana kwe-glycerol ukuze sikusize uqonde ngokugcwele lesi sakhiwo esibalulekile somzimba kanye nokubaluleka kwayo ekusetshenzisweni okuhlukahlukene.
Kuyini Ukuminyana kweGlycerol?
Ukuminyana kwe-Glycerine isisindo seyunithi ngayinye ye-glycerine. Ngokuvamile, ukuminyana kwe-glycerin cishe ku-1.26 amagremu ku-cubic centimeter ngayinye (g/cm³) ekamelweni lokushisa (20°C). Ukuminyana kungenye yezinto ezibonakalayo eziyisisekelo futhi kubalulekile ekuqondeni ukuziphatha kwayo ezindaweni ezihlukahlukene. IGlycerol inokuminyana okuphezulu kunamanzi (1.00 g/cm³), okusho ukuthi emanzini i-glycerol iyasinki.
Umthelela wezinga lokushisa kubuningi be-glycerol
Ukuminyana kweGlycerol akulona inani elingaguquki, kushintsha ngokushisa. Lapho izinga lokushisa likhuphuka, ukuminyana kwe-glycerine kuncipha kancane. Isizathu salokhu umphumela wokwandisa okushisayo: lapho izinga lokushisa likhuphuka, amandla e-kinetic ama-molecule e-glycerol ayanda futhi ibanga phakathi kwama-molecule liyakhula, okuholela ekunciphiseni kwabantu. Ngakho-ke, ekusebenzeni, ukuminyana kwe-glycerine kudinga ukulungiswa ngokuya ngemibandela yokusetshenziswa (isb. izinga lokushisa elizungezile).
Umehluko Ekuminyana Kwe-Glycerine Yokuhlanzeka Okuhlukile
Ukuhlanzeka kwe-glycerine kuthinta kakhulu ukuminyana kwayo. Ngokuvamile, i-glycerine yezimboni inokuhlanzeka okungama-95% noma ngaphezulu, kuyilapho i-glycerine yokusetshenziswa kwemithi noma yezimonyo ingaba msulwa ngo-99.5% noma ngaphezulu. I-glycerin emsulwa ephezulu ivamise ukuba nokuminyana eduze nenani lethiyori (1.26 g/cm³) ngenxa yokuthi iqukethe ukungcola okumbalwa. I-glycerin ehlanzekile ephansi ingase ibe namanzi noma ezinye izincibilikisi, ezingase zibangele ukuminyana okuphansi.
Ukubaluleka Kokuminyana KweGlycerine Ezicelweni
Ukuqonda ukuminyana kwe-glycerine kubalulekile ezinhlelweni eziningi zezimboni. Embonini yezimonyo, lapho i-glycerine isetshenziswa njenge-humectant, ukuminyana kwayo kuthinta ukuthungwa nokuzinza komkhiqizo; ekucubunguleni ukudla, ukuminyana kwe-glycerine kuthinta ukufana kokuxuba kanye nomuzwa womlomo wama-sweeteners; futhi ekukhiqizeni amakhemikhali, ukuminyana kwe-glycerine kuyipharamitha ebalulekile yokubala ukugeleza kwayo, ukuxuba kanye nezinga lokuphendula.
Ungalinganisa kanjani ukuminyana kwe-glycerol?
Ukuminyana kweGlycerol kuvame ukukalwa kusetshenziswa indlela ethize yebhodlela lamandla adonsela phansi, i-densitometer noma i-digital densitometer. Indlela ethile yebhodlela lamandla adonsela phansi ibala ukuminyana ngokukala isisindo sevolumu enikeziwe ye-glycerin. Ama-densitometers (isb. Ama-densitometer e-Abbey) asebenzisa izici zokunyakazisa koketshezi, kuyilapho ama-densitometer edijithali asebenzisa ubuchwepheshe bokudlidliza ukuze afinyelele izilinganiso zokuminyana ezinembe kakhulu. Izindlela zokulinganisa ezihlukene zifanele izidingo zokunemba ezihlukene kanye nezimo zokusebenzisa.
Isifinyezo
Ukuminyana kweGlycerol kuyisici esibalulekile ekuqondeni izakhiwo zayo zamakhemikhali nokusebenza kokusetshenziswa kwayo. Noma ngabe kusenqubweni yokukhiqiza noma ekuthuthukisweni kokusebenza komkhiqizo kokugcina, kubalulekile ukuqonda kanye nokuba yinkosi eshintshayo yomthetho wokuminyana kwe-glycerol kanye nendlela yokulinganisa. Kwethenjwa ukuthi ukuhlaziya okuphelele kwaleli phepha kokuminyana kwe-glycerol kuzonikeza ulwazi olubalulekile kochwepheshe bezimboni ezihlukahlukene.
Ngengxoxo ekulesi sihloko, sifunde ukuthi ukuminyana kwe-glycerol kuthinteka kanjani izici ezifana nezinga lokushisa nokuhlanzeka, kanye nokubaluleka kwayo ekusetshenzisweni okuhlukahlukene nezindlela zokulinganisa. Uma udinga idatha enemininingwane eyengeziwe noma ulwazi mayelana nokuminyana kwe-glycerol kuhlelo lokusebenza oluthile, sicela wenze olunye ucwaningo olusekelwe ezidingweni zakho ezithile.
