Kutheni iityhubhu zeSapphire zibonelela ngokusebenza okuphezulu kangaka?

Iityhubhu zesafire zaziwa ngokukwazi kwazo ukugcina uzinzo lwesakhiwo nokusebenza phantsi koxinzelelo olukhulu lomzimba nolweekhemikhali. Kwiinkqubo zoxinzelelo oluphezulu, zisetyenziswa njengeenqanawa zokuthintela kunye neefestile zokujonga, zibonelela ngendawo ekhuselekileyo nengangeniyo yokuhlalutya ulwelo kunye neegesi. Ngenxa yamandla azo aphezulu okuxinzelela kunye nokumelana nokukrwela, iityhubhu zesafire zikwafanelekile kwiindawo ezichaphazela impembelelo enamandla yoomatshini okanye ukujikeleza rhoqo kobushushu.

Ezi tyhubhu zikhethekile kubuchule bazo bokusebenza kumaqondo obushushu afikelela kwi-2000°C ngaphandle kokuthambisa okanye ukuguquguquka. Ngokungafaniyo nezinye izinto ezininzi ze-ceramic okanye zeglasi, i-sapphire igcina imo yayo kunye neempawu zayo zoomatshini nokuba kumaqondo obushushu aphezulu. Olu buchule lubalulekile kwiindlela apho ubukhulu obuhambelanayo bomzimba bubalulekile ekutywineni, ekugqumeni, okanye ekulungelelaniseni—njengakwiinkqubo zezindlu ze-thermocouple.

Ukukhanya kwazo okubonakalayo kwi-spectrum ebanzi—ukusuka kwi-ultraviolet (0.3 μm) ukuya kwi-infrared (5 μm)—kongeza olunye ulwelo lomsebenzi. Olu phawu luvumela iityhubhu ze-sapphire ukuba zingasebenzi nje kuphela njengezinto zokwakha kodwa zikwaxhasa iinkqubo ze-optical ezidibeneyo zokujonga ngexesha langempela kunye nokulinganisa okusekwe kwi-laser.

Iityhubhu zeSapphire kwi-Thermocouple Protection

Ii-thermocouples zizixhobo ezibalulekileyo zokuvavanya ubushushu ezisetyenziswa kumashishini ahlukeneyo ukusuka kwi-aerospace kunye ne-metallurgy ukuya kulwakhiwo lwe-semiconductor kunye nokucubungula iikhemikhali. Nangona kunjalo, ii-thermocouples zizixhobo ezibuthathaka ezinokonakala ngokukhawuleza xa zichatshazelwa ngqo ziigesi ezisabelayo, iindawo zeplasma, okanye imijikelo yokufudumeza/yokupholisa ngokukhawuleza. Ukuthintela ezi ngxaki, iityhubhu zesafire zisebenza njengeeshelufu ezifanelekileyo zokukhusela ii-thermocouples.

Ukuhanjiswa kobushushu kwesafire kuqinisekisa ukudluliselwa kobushushu ngokukhawuleza nangokuchanekileyo kwi-thermocouple ngaphakathi kwityhubhu, okuvumela ukujonga ubushushu ngexesha langempela ngelixa kukhusela i-sensor kwizinto ezirhabaxa, ukukrazula koomatshini, kunye noxinzelelo lobushushu. Olu lungelelwaniso lobushushu kunye nokuhanjiswa kwenza iityhubhu zesafire zilungele ngokukodwa ukukhuselwa kwe-thermocouple kwiindawo ezinobundlobongela.

Ukongeza, ukungangeni kweekhemikhali zesafire kuthintela naluphi na ungcoliseko lwendalo esingqongileyo. Oku kubaluleke kakhulu kwizicelo ezicocekileyo kakhulu ezifana nokucubungula i-semiconductor wafer, iinkqubo zokubulala iintsholongwane zonyango, okanye amagumbi obushushu aphezulu. Ukungabikho kwempendulo phakathi kwesafire kunye neekhemikhali ezirhabaxa ezifana ne-fluorine plasma, i-hydrochloric acid, okanye iintsimbi ezinyibilikisiweyo kuqinisekisa ukuthembeka kwenkqubo kunye nokuchaneka kokulinganisa.

Ngaphezu koko, iityhubhu zesafire ziyamelana kakhulu nokuguguleka kwaye aziboli xa zichatshazelwa ixesha elide ziinxalenye zamandla aphezulu okanye imisebe ye-UV/IR enamandla. Oku kuqina kwandisa ubomi beenzwa ze-thermocouple, kunciphisa iindleko zokulungisa kunye nexesha lokungasebenzi kwenkqubo.
