Kufotokozera Kwachidule:

Machubu a safiro, opangidwa kuchokera ku single-crystal aluminium oxide (Al₂O₃), ndi zigawo zogwira ntchito kwambiri zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Kuphatikiza kwawo kosagwirizana ndi kukana kwamafuta, mphamvu zamakina, kukhazikika kwamankhwala, komanso kuwonekera kwa kuwala kwawapanga kukhala ofunikira kwambiri pamakina achilengedwe. Chimodzi mwazinthu zofunika kwambiri komanso zovomerezeka kwambiri ndikuteteza ma thermocouples - zida zozindikira kutentha zomwe nthawi zambiri zimagwira ntchito mwaukali, kutentha kwambiri, kapena kuwononga. Nkhaniyi imapereka chithunzithunzi chakuya cha katundu wa safiro chubu, makhalidwe apakati, ntchito zazikulu, makamaka ntchito yawo mu chitetezo cha thermocouple.

Chifukwa chiyani Sapphire Tubes Amapereka Kuchita Kwapamwamba Chotere?

Machubu a safiro amadziwika chifukwa cha kuthekera kwawo kukhalabe okhazikika komanso okhazikika pansi pa kupsinjika kwakuthupi ndi kwamankhwala. M'makina othamanga kwambiri, amagwiritsidwa ntchito ngati zombo zonse zosungiramo zinthu komanso mazenera owonera, omwe amapereka malo otetezeka komanso opanda mpweya owunikira madzi ndi mpweya. Chifukwa cha mphamvu zawo zophatikizika kwambiri komanso kukana kukanda, machubu a safiro amayenereranso malo omwe amakhudza kwambiri mawotchi kapena kupalasa njinga pafupipafupi.

Machubuwa ndi apadera chifukwa amatha kugwira ntchito pa kutentha mpaka 2000 ° C popanda kufewetsa kapena kupunduka. Mosiyana ndi zida zina zambiri za ceramic kapena magalasi, safiro imakhalabe ndi mawonekedwe ake komanso makina ake ngakhale kutentha kwambiri. Kuchita uku ndikofunikira kwambiri pamachitidwe omwe miyeso yofananira ndiyofunikira pakusindikiza, kutsekereza, kapena kuyanjanitsa —monga m'makina anyumba a thermocouple.

Kuwonekera kwawo kowoneka bwino pamawonekedwe otakata-kuchokera ku ultraviolet (0.3 μm) mpaka kumawonekera mpaka infuraredi (5 μm) - kumawonjezera magwiridwe antchito ena. Mbali imeneyi imalola machubu a safiro kuti asamangogwira ntchito ngati zigawo zamapangidwe komanso kuthandizira machitidwe ophatikizika a kuwala kwa nthawi yeniyeni ndi miyeso yochokera ku laser.

Machubu a Sapphire mu Chitetezo cha Thermocouple

Ma thermocouples ndi ma sensor ofunikira a kutentha omwe amagwiritsidwa ntchito m'mafakitale ambiri kuyambira kumlengalenga ndi zitsulo mpaka kupanga semiconductor ndi kukonza mankhwala. Komabe, ma thermocouples ndi zida zomvera zomwe zimatha kuwonongeka mwachangu zikakhudzidwa mwachindunji ndi mpweya wotuluka, malo a plasma, kapena kutentha kwachangu / kuzizira. Pofuna kupewa izi, machubu a safiro amagwira ntchito ngati mikanda yabwino yotetezera ma thermocouples.

Kutentha kwa safiro kumatsimikizira kutentha kwachangu komanso kolondola ku thermocouple mkati mwa chubu, kulola kuyang'anira kutentha kwa nthawi yeniyeni ndikutchinjiriza sensa kuzinthu zowononga, ma abrasion mechanical, and thermal shock. Kukhazikika uku kwa kutchinjiriza ndi conduction kumapangitsa machubu a safiro kukhala ogwirizana ndi chitetezo cha thermocouple m'malo ovuta.

Kuphatikiza apo, kusakhazikika kwamankhwala a safiro kumalepheretsa kuipitsidwa kulikonse kwa chilengedwe. Izi ndizofunikira kwambiri pakugwiritsa ntchito zinthu zoyera kwambiri monga makina opangira ma semiconductor wafer, njira zachipatala zotsekereza, kapena zipinda zotentha kwambiri. Kusachitapo kanthu pakati pa safiro ndi mankhwala aukali monga fluorine plasma, hydrochloric acid, kapena zitsulo zosungunuka zimatsimikizira kudalirika kwadongosolo komanso kuyeza kwake.

Kuphatikiza apo, machubu a safiro samva kuvala ndipo samanyozeka akakumana ndi tinthu tambiri tambiri kapena ma radiation a UV/IR. Kulimba uku kumakulitsa moyo wa masensa a thermocouple, kuchepetsa mtengo wokonza ndi kutsika kwadongosolo.

Kugwiritsa Ntchito Mwambiri kwa Machubu a Sapphire

Ngakhale chitetezo cha thermocouple ndi chimodzi mwazinthu zoyimilira, machubu a safiro amagwiritsidwanso ntchito kwambiri m'magawo ena apamwamba komanso mafakitale. Izi zikuphatikizapo:

Plasma Processing: Machubu a safiro amakhala ngati zotsekera mu plasma etching ndi deposition system, pomwe kukana kwawo kwamankhwala kumalepheretsa kupanga tinthu.
Kuwunikira Kwambiri Kutentha: Kuwonekera kwawo komanso kukana kutentha kumawapangitsa kukhala maenvulopu abwino a UV, kuwoneka, ndi misonkhano ya nyali ya IR.
Chithandizo cha Madzi ndi jekeseni wa Gasi: Machubu a safiro amagwiritsidwa ntchito m'makina omwe kuwongolera bwino kwamadzi kapena mpweya wopanikizika kwambiri kumafunika.
Zida Zachipatala ndi Zamankhwala: Chifukwa cha zomwe ali ndi bio-inert, machubu a safiro ndi otetezeka kuti agwiritsidwe ntchito pazida zosawilitsidwa kapena zoyikika.
Spectroscopy ndi Optical Analysis: Kumveka kwawo kowoneka bwino kumalola kuphatikizika kosasunthika m'makina owoneka bwino pamakina amankhwala kapena zachilengedwe.

M'magawo onsewa, machubu a safiro amapereka kukhazikika kwamakina komanso kukana kwamankhwala, kuwonetsetsa kuti magwiridwe antchito azikhala nthawi yayitali m'malo ovuta kwambiri.

Makhalidwe a Sapphire Tubes

Machubu a safiro ali ndi kuphatikiza kosowa kwa zinthu zofunika:

Wide Optical Transmission Range: Kuchokera pa 0.3 μm (UV) mpaka 5 μm (IR), yoyenera makina a laser, kuyang'anira maso, ndi miyeso ya in-situ.
Kuuma Kwambiri: Ndi kulimba kwa Mohs kwa 9, safiro ndi pafupifupi scratchproof, kungoposa diamondi.
High Melting Point: Sapphire imakhalabe yokhazikika mpaka 2030°C.
Exceptional Thermal Conductivity: Kusamutsa bwino kutentha, kofunikira pakugwiritsa ntchito thermocouple.
Chemical Kukhazikika: Kusamva zidulo, alkali, ndi zitsulo zosungunuka, kupatula mchere wotentha wa caustic.
High Electrical Insulation: Zoyenera pamagetsi ndi magetsi okwera kwambiri.
Dimensional Kukhazikika: Amasunga umphumphu pansi pa kupsinjika kwa kutentha kapena katundu wamakina.

Ubwino Wogwiritsa Ntchito Machubu a Sapphire Pama Thermocouples

Kuphatikiza kwa machubu a safiro mumisonkhano ya thermocouple kumabweretsa zabwino zambiri:

Kulondola kwa Sensor Yowonjezera: Thermal conductivity imathandizira kuzindikira kutentha kofulumira.
Moyo Wowonjezera wa Sensor: Kukana dzimbiri ndi abrasion kumateteza mkati mwa thermocouple.
Kuchepetsa Nthawi Yopuma: Kutsika kwafupipafupi kwa kulephera kwa sensa ndi zosowa za recalibration.
System Purity: Kusakhazikika kwa Chemical kumalepheretsa kuipitsidwa, kofunikira pakuyeretsa zipinda.
Mipikisano magwiridwe antchito: Zimaphatikiza chitetezo chamafuta ndi kuwala kwa kuwala kuti zigwiritsidwe ntchito pawiri pakuzindikira ndi kuyang'anira.
