Ibhodwe le-tungsten elincibilikayo i-tungsten crucible enekhava Isithombe esifakiwe

Incazelo emfushane:

I-Tungsten crucibles kanye nama-furnaces avame ukusetshenziswa ekusetshenzisweni kwezinga lokushisa eliphezulu njengokuphonsa kwensimbi, i-sintering, nokukhiqizwa kwezitsha zobumba nezinye izinto ezisezingeni eliphezulu. Iphuzu lokuncibilika eliphakeme le-Tungsten, i-thermal conductivity enhle kakhulu nokumelana namakhemikhali kuyenza ibe into efanelekile yalezi zinhlelo zokusebenza.

Isebenza kanjani i-crucible?

I-crucible isitsha esiklanyelwe ukumelana namazinga okushisa aphezulu, ngokuvamile asetshenziselwa ukuncibilika, i-calcine, noma ukucubungula izinto ezisetshenziswayo emazingeni okushisa aphezulu. Ama-crucibles ngokuvamile ayenziwa ngezinto ezifana ne-graphite, izitsha zobumba, noma izinsimbi eziphikisayo ezifana ne-tungsten.

Ukusebenza okuyisisekelo kwe-crucible kuhilela lezi zinyathelo ezilandelayo:

1. Ukubekwa uphawu: Umsebenzi oyinhloko we-crucible ukuqukatha impahla ecutshungulwayo, njengensimbi, i-alloy noma ezinye izinto, ngesikhathi sokushisisa noma ukuncibilika. Ukumelana nezinga lokushisa okuphezulu kwe-crucible kuvimbela izinto ukuthi zingaphunyuki noma zisabele ngendawo ezungezile.

2. Ukudlulisa ukushisa: Uma kufakwe esithandweni noma kwezinye izinto zokushisisa, i-crucible idonsa ukushisa futhi ikudlulisele ezintweni ezingaphakathi. Lokhu kuletha okuqukethwe kwe-crucible ezingeni lokushisa elidingekayo ukuze lincibilike, lincibilike, noma ezinye izinqubo zokushisa.

3. Ukuvikela: I-crucible iphinde inikeze ukuvikeleka kokubalulekile okucutshungulwayo. Isibonelo, esimweni sokuncibilika kwensimbi, ama-crucibles asiza ukuvimbela i-oxidation noma ukungcoliswa kwensimbi encibilikisiwe ngokunikeza indawo evaliwe.

4. Ukuthela noma Ukusakaza: Uma into engaphakathi kwe-crucible isifinyelele esimweni esifunekayo, njengefomu elincibilikisiwe, i-crucible ingasetshenziswa ukuthela noma ukuphonsa into esikhunjini noma esinye isitsha ukuze kuqhutshekwe nokucubungula.

Endabeni yama-tungsten crucibles, indawo yawo ephezulu yokuncibilika kanye nokumelana nokuhlaselwa kwamakhemikhali kuwenza afaneleke ukuphatha izinqubo zokushisa okuphezulu kakhulu, njengokuncibilika kwezinsimbi eziphikisayo noma ezinye izinto ezisezingeni eliphezulu.

Sekukonke, ukuklama nezinto ezibonakalayo ze-crucibles zibenza bakwazi ukumelana namazinga okushisa aphezulu, aqukethe izinto, lula ukudluliswa kokushisa, nokuvikela izinto ezicutshungulwayo ezicini zemvelo, okuzenza zibe ithuluzi elibalulekile ezinhlobonhlobo zezicelo zokushisa okuphezulu.

Kungani i-crucible ishisiswe ngesivalo?

I-crucibles ivamise ukushisisa nesivalo sivaliwe ngenxa yezizathu ezilandelayo:

1. Ukuvalwa: Isivalo sisiza ukuvala izinto ezicutshungulwa ku-crucible, zivimbele ukuthi zingachitheki noma zichaphaze lapho zifinyelela amazinga okushisa aphezulu. Lokhu kuvalwa kubaluleke kakhulu ezintweni ezingase zisabele endaweni ezungezile noma ezinqubweni ezidinga indawo elawulwayo.

2. Ukuvikela: Isivalo sihlinzeka ngokuvikeleka kwezinto ezingaphakathi kwe-crucible ekungcoleni, ekufakweni kwe-oxidation, noma ezinye izici zemvelo. Lokhu kubaluleke kakhulu uma usebenza ngezinto ezibucayi noma lapho wenza izinqubo zokushisa okuphezulu ezidinga umoya othile.

3. I-Insulation: Ukugcina isivalo ku-crucible kusiza ukugcina ukushisa ngaphakathi kwesitsha, kukhuthaza ngisho nokushisa kwezinto futhi kuvimbela ukulahlekelwa ukushisa endaweni ezungezile. Lokhu kubalulekile ukufeza ukushisa okungaguquki nokulawulwa ngesikhathi sokwelashwa kokushisa.

4. Ukulawulwa komkhathi: Kwezinye izimo, isivalo singasiza ukulawula umoya ngaphakathi kwe-crucible ukuze kugcinwe ukwakheka okuthile kwegesi noma ukucindezela phakathi nenqubo yokushisisa. Lokhu kubalulekile ekuphatheni okuthile nokusabela kwamakhemikhali.

Sekukonke, ekusetshenzisweni kwezinga lokushisa eliphezulu, kuwumkhuba ojwayelekile ukushisa ama-crucibles anezivalo ukuze kuqinisekiswe ukuvala, ukuvikelwa, ukufakwa, nokulawulwa kwendawo yokucubungula.
