Isingeniso

Embonini yesimanje, ukuqapha izinga lokushisa okunembile kuyingxenye ebalulekile yokulawula inqubo, ukuqinisekiswa kwekhwalithi, nezinhlelo zokuphepha. Ama-thermocouples—izinzwa zokushisa ezisetshenziswa kakhulu—avame ukuchayeka ezindaweni eziyinselele ezifana namazinga okushisa aphezulu, amakhemikhali abolayo, amasistimu evacuum, nezinkambu ze-plasma. Ukuvikela lezi zinzwa ngokuphumelelayo kubalulekile ekuzinzeni kokusebenza. Amashubhu esafire, enziwe nge-synthetic single-crystal aluminium oxide, afakazele ukuthi aphakathi kwezinto ezinokwethenjelwa kakhulu zokuvikela okunjalo. Lesi sihloko sihlola izici eziyingqayizivele zamashubhu esafire, ukusetshenziswa kwawo okuhlukahlukene, futhi ikakhulukazi, ukusebenza kwawo okukhethekile njengamashethi okuvikela e-thermocouple.

I-Superior Material Yezicelo Ezifunayo

Isafire iwuhlobo lwecrystalline lwe-aluminium oxide (Al₂O₃) futhi ibalwa ngaphansi nje kwedayimane ngokobunzima, ithola u-9 esikalini se-Mohs. Lobu bunzima obuyinqaba benza amashubhu esafire amelane kakhulu nokuklwejwa, ukuhuzuka, kanye nomthelela wokusebenza, ngisho nangaphansi kokusetshenziswa njalo noma kakhulu.

Ngalé kwamandla emishini, amashubhu esafire aziswa kakhulu ngokumelana kwawo namakhemikhali. Zihlala zizinzile futhi zingasebenzi phambi kwama-asidi amaningi, izincibilikisi, namagesi asebenzayo, okuhlanganisa i-hydrogen fluoride, i-chlorine, nezinhlanganisela zesulfure. Lokhu kuzivumela ukuthi zisebenze ngokuphumelelayo ezinqubweni ezibandakanya amakhemikhali anolaka noma i-plasma.

Ukwengeza, ukusebenza okushisayo kwesafire kuyamangaza. Imelana nokuchayeka isikhathi eside emazingeni okushisa afinyelela ku-2000°C kuyilapho igcina ubuqotho bayo besakhiwo. I-thermal conductivity yayo isekela ukudluliswa kokushisa okusheshayo, isici esibaluleke kakhulu uma sisetshenziswa ezinhlelweni zokuzwa izinga lokushisa.

Enye inzuzo ebalulekile ukukhanya kwayo kokubona kuwo wonke amaza e-ultraviolet, abonakalayo, namaza e-infrared—kusuka cishe ku-0.3 μm kuya ku-5 μm. Lokhu kwenza amashubhu esafire afanelekele inzwa yokubona noma amasistimu okuqapha ahlanganisiwe we-thermal-optical.

Ama-Thermocouples kanye Nesidingo Sokuvikela

Ama-Thermocouples ayizingxenye ezibalulekile ohlelweni olubanzi lwezinhlelo, kusukela ezithandweni zensimbi nezinjini zomoya ophephela emhlane kuya kuma-semiconductor reactor kanye nemishini yenqubo yamakhemikhali. Lawa madivaysi akhiqiza i-voltage ngokusekelwe emehlukweni wezinga lokushisa phakathi kwezinsimbi ezimbili ezingafani ezihlanganiswe ekugcineni. Nakuba ama-thermocouples eguquguquka futhi eqinile, ukuchayeka kwawo ngokuqondile ekushiseni, ezintweni ezibolayo, kanye nokushaqeka komshini kungafinyeza kakhulu impilo yawo yesevisi noma kwehlise ukunemba kokufundwa kwezinga lokushisa.

Yilapho amashubhu esafire eqala khona ukudlala njengamashethi okuvikela. Ngokuvala i-thermocouple ngaphakathi kweshubhu lesafire, inzwa ihlukanisiwe nemvelo enokhahlo kuyilapho isavumela ukudluliswa kokushisa okusebenzayo. Umphumela uba inzwa ehlala isikhathi eside, ethembeke kakhudlwana egcina ukunemba okungashintshi ngisho nangemva kokuchayeka isikhathi eside kuzimo zokusebenza ezinolaka.

I-thermal conductivity ye-Sapphire ivumela ukushisa ukuthi kufinyelele ku-thermocouple ngokushesha nangokulinganayo, kunciphise izinga lokushisa nokuthuthukisa isikhathi sokuphendula. Ngaphezu kwalokho, ukumelana kwayo nokuhlaselwa kwamakhemikhali kuqinisekisa ukuthi inzwa ayiphazanyiswa yizinsalela, ukugqwala, noma ukwakheka kwezinto ezibonakalayo—izindaba ezivame ukuhlupha imikhono yokuzivikela yensimbi noma ye-ceramic.

Sebenzisa Amakesi Ekugadweni Kwezinga Lokushisa

Ezithandweni zokushisa eziphezulu, amashubhu esafire ngokuvamile asetshenziswa ukuze avikele ama-thermocouples aqapha izimo zenqubo ebalulekile. Ukuzinza kwawo kwamakhemikhali kubalulekile emkhathini ocebile ngamagesi e-halogen, izinsimbi ezincibilikisiwe, noma umhwamuko osebenzayo. Ngokwesibonelo:

  • Ukukhiqiza I-Semiconductor: Amashethi e-Sapphire avikela ama-thermocouples ngesikhathi sokukhula kwe-epitaxial, i-wafer annealing, nezinqubo ze-doping, lapho izindawo ezihlanzekile nokulawula izinga lokushisa okunembile kubalulekile.

  • Ama-Chemical Reactors: Ekuphenduleni kwe-catalytic noma izindawo zomhwamuko obolayo, amashubhu esafire aqinisekisa ukuvikeleka kwesikhathi eside kwezivivinyo zokushisa, aqede ukukhathazeka ngokungcoliswa.

  • Vacuum Furnaces: Amashubhu e-Sapphire avimbela i-oxidation kanye nokulimala kwemishini kuma-thermocouples ngenkathi esebenza ngaphansi kwe-vacuum noma amagesi angenayo ingcindezi ephansi.

  • Combustion Systems: Izinjini zamajethi, izinjini zegesi, nezishisi zezimboni ngokuvamile zithembele kuma-thermocouples avikelwe ngesafire ukuze kuqashwe amazinga okushisa adlulele ukuze asebenze kanye nokwenza kahle ukuphepha.

Ngokusebenzisa amashubhu esafire, onjiniyela bayakwazi ukusebenzisa ama-thermocouples ezimeni ebezingaba yingozi kakhulu kumashethi ensimbi ajwayelekile noma engilazi. Lokhu kunweba ububanzi bokusebenza bezinhlelo zokuqapha ezishisayo futhi kuthuthukise ukusebenza kwazo kwesikhathi eside.

Izicelo ezengeziwe zezimboni zamashubhu e-Sapphire

Ngenkathi ukuvikelwa kwe-thermocouple kuwuhlelo oluhamba phambili, amashubhu esafire asetshenziswa kobunye ubuchwepheshe obuningi obuthuthukile:

  • Amalambu Akhipha Amandla Aphezulu (HID).: Njengezinto zemvilophu, amashubhu esafire amelana nokushisa okukhulu nemisebe ye-UV/IR ngaphandle kokufiphaza noma ukuthamba.

  • Ama-Plasma Etching Chambers: Isetshenziswa njengezindawo zokubuka kanye nemikhumbi yokuvikela ngenxa yokumelana nokuguguleka kwayo.

  • I-Optical Sensing esemgqeni: Nika amandla i-spectroscopy, imaging, kanye nokuxilongwa kwe-laser ngokusebenzisa amapayipi enqubo ngaphandle kokungcolisa okuphakathi.

  • Ukwelapha Amanzi kanye Namadivayisi Ezokwelapha: Ngenxa ye-bio-inertness yawo kanye nokumelana namakhemikhali, amashubhu esafire alungele amasistimu adinga ubunyumba nokungasebenzeki kabusha.

  • Laser Delivery Systems: Amashubhu eSapphire aqondisa imishayo yamandla aphezulu ngokulahleka okuncane kokubona kanye nokuzinza okukhulu kwe-thermal.

Lezi zinhlelo zokusebenza zizuza ezicini eziyinhloko zesafire—ukungasebenzi kwamakhemikhali, ukukhanya okukhanyayo, ubulukhuni obuphezulu, nokuzinza kwe-thermal—kuzo zonke izimboni ezihlukahlukene njenge-aerospace, ukunakekelwa kwezempilo, amakhemikhali e-petrochemicals, ne-electronics.
