I-Quartz Beaker ephezulu yokumelana nokumelana nokushisa komkhawulo

I-Quartz Beaker ephezulu yokumelana nokumelana nokushisa komkhawulo
Umkhawulo wokumelana kwamazinga okushisa we-quartz beakers uthonywa yizici ezahlukahlukene. Ngezansi kwesingeniso esinemininingwane sokumelana okuphezulu kokushisa ngaphansi kwezimo ezahlukahlukene:

Izinga lokushisa elide lokusebenzisa
Amazinga okushisa athambisa ingilazi ye-quartz cishe ngezinga elingu-1730 degree, futhi ngokuvamile angasetshenziselwa isikhathi eside nge-1100 degree.
Kukhona futhi idatha ekhombisa ukuthi ama-quartz beaker angasebenzela isikhathi eside cishe ngezinga elingu-1000. Lokhu kungenxa yokuthi ngaphakathi kobubanzi bokushisa obunjalo, i-quartz beaker ingagcina izakhiwo ezizinzile zomzimba nangamakhemikhali, ngaphandle kokungcola noma ukulimala, ukuqinisekisa inqubekela phambili ejwayelekile yokuhlolwa.
Ukushisa kwesikhashana okufushane
Ukushisa okuphezulu kwe-- ukusetshenziswa kwethemu kungafinyelela℃1450. Kukhona imininingwane ekhombisa ukuthi izinga lokushisa lingafinyelela amazinga acishe abe ngu-1400 esikhathini esifushane. Kodwa-ke, amafushane - ukuvezwa kwesikhathi sokushisa okuphezulu akuwona izingozi. Noma ngaphansi kwamafuphi - isikhathi sokushisa esiphakeme, ama-quartz bacher angahle aguquke ngokucashile ngokomzimba, kepha akuthinti ukusebenza kwawo okuyisisekelo.
Umehluko kubabeki be-quartz akhiqizwa izinqubo ezahlukahlukene
Ingilazi ye-Quartz ekhiqizwe ngezinqubo ezahlukahlukene inamaphoyinti okushisa ahlukene kancane (indawo yokushisa, iphuzu lokufaka, indawo yokuthambisa) ngenxa yokuqukethwe kokuqukethwe kwe-hydroxyl, okuqukethwe kwensimbi, kanye nenani le-doping. Ngokuvamile, izinga lokushisa elincibilikayo le-quartz ingilazi liyi-1900-2000 degree, izinga lokushisa le-gasterication lingama-2100 degree, futhi inani elincane lokuhwamuka liqala ngaphezulu kwe-1800 degree. Ngakho-ke, izinga lokushisa le-thermal le-quartz ingilazi kufanele lilawulwe phakathi kwe-1780-1820 degree, futhi izinga lokushisa elincibilikayo kufanele lilawulwe cishe ngo-1950 degree, ngaphandle kwalokho kuzokhiqizwa inani elikhulu lama-bubble lizokwenziwa ngenxa yendawo.

Lapho usebenzisa i-quartz beaker, ukuze kuqinisekiswe ukuphepha kokuphepha nokunemba, kuyadingeka ukuthi ulandele ngokuqinile ibanga lokushisa kwalo ukuze ugweme ukulimala kwe-beaker noma ngisho nezingozi zokuphepha ezibangelwa ukweqa umkhawulo wokushisa. Ngasikhathi sinye, landela izinyathelo zokusetshenziswa ukuze usebenzise, ​​njengokuphatha ngokunakekela, ukusula okuhlanzekile ngaphambi kokusebenzisa, futhi ugweme ukuxhumana nezinto ze-alkali.
