Tubhu reSapphire rekudzivirira Thermocouple - Kunyatsopisa kwakanyanya munzvimbo dzakaoma

Tsananguro pfupi:

Machubhu eSapphire, akagadzirwa ne single-crystal aluminum oxide (Al₂O₃), zvinhu zvinoshanda zvakanyanya zvinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Musanganiswa wavo usingaenzaniswi wekudzivirira kupisa, simba remakanika, kugadzikana kwemakemikari, uye kujeka kwemaziso kwakaita kuti ave chinhu chakakosha mumasisitimu ezvakatipoteredza zvakanyanya. Chimwe chezvinhu zvinonyanya kukosha uye zviri kushandiswa zvakanyanya ndechekudzivirira ma thermocouples—zvishandiso zvinonzwa kupisa zvinowanzo shanda mumamiriro ekupisa, kupisa kwakanyanya, kana ngura. Chinyorwa chino chinopa pfupiso yakadzama yehunhu hwechubhu yesapphire, hunhu hwayo, mashandisirwo akakosha, uye kunyanya basa rawo mukudzivirira thermocouple.

Sei Machubhu eSapphire Achipa Kushanda Kwazvo Kwakanaka?

Machubhu eSapphire anozivikanwa nekugona kwawo kuchengetedza kugadzikana kwechimiro uye mashandiro emuviri pasi pekumanikidzwa kwakanyanya kwemuviri uye kwemakemikari. Mumasisitimu ane kumanikidzwa kwakanyanya, anoshandiswa semidziyo yekudzivirira uye semahwindo ekutarisa, zvichipa nzvimbo yakachengeteka uye isina mvura yekuongorora mvura nemagasi. Nekuda kwesimba rawo rekudzvanya uye kuramba kukwenya, machubhu eSapphire akakodzerawo munzvimbo dzine simba rakasimba remakanika kana kupisa nguva nenguva.

Machubhu aya akasiyana nekugona kwawo kushanda patembiricha inosvika 2000°C pasina kupfava kana kuchinja chimiro. Kusiyana nezvimwe zvinhu zvakawanda zveceramic kana girazi, sapphire inoramba iine chimiro chayo uye hunhu hwayo hwemakanika kunyangwe patembiricha yakakwira. Kushanda uku kwakakosha mukushandiswa uko zviyero zvemuviri zvakaenzana zvakakosha pakuvhara, kuputira, kana kurongeka—senge mu thermocouple housing systems.

Kujeka kwavo kwemaziso mumhando dzakasiyana-siyana—kubva pa ultraviolet (0.3 μm) kusvika painoonekwa kusvika pa infrared (5 μm)—kunowedzera rimwe basa. Hunhu uhwu hunobvumira machubhu esapphire kwete kungoshanda sezvikamu zvemaumbirwo chete asiwo kutsigira masisitimu emaziso akabatanidzwa ekutarisa panguva chaiyo uye kuyerwa kwe laser.

Machubhu eSapphire muThermocouple Protection

Mathermocouples inyanzvi dzinoona tembiricha dzinoshandiswa mumaindasitiri akasiyana-siyana kubva mundege nesimbi kusvika pakugadzira ma semiconductor nekugadzirisa makemikari. Zvisinei, mathermocouples zvishandiso zvinonzwa zvinogona kuora nekukurumidza kana zvikasangana nemagasi anochinja-chinja, plasma environments, kana kukurumidza kupisa/kutonhodza. Kudzivirira matambudziko aya, machubhu esapphire anoshanda senzvimbo dzakakodzera dzekudzivirira mathermocouples.

Kufambiswa kwemafuta eSapphire kunoita kuti kupisa kupfuure nekukurumidza uye nemazvo mu thermocouple iri mukati mechubhu, zvichibvumira kutarisa tembiricha panguva chaiyo ukuwo zvichidzivirira sensor kubva kuzvinhu zvinoparadza, kukweshana kwemuchina, uye kuvhunduka kwekupisa. Kuenzana uku kwekudzivirira kupisa uye kufambiswa kwemafuta kunoita kuti machubhu eSapphire akwanise kudzivirirwa ne thermocouple munzvimbo dzine hasha.

Pamusoro pezvo, kusashanda zvakanaka kwemakemikari esapphire kunodzivirira kusvibiswa kwenzvimbo inogadzirwa. Izvi zvakakosha zvikuru mukushandiswa kwemhando yepamusoro senge semiconductor wafer processing, medical sterilization systems, kana high-vacuum thermal chambers. Kusavapo kwekuita pakati pesapphire nemakemikari akasimba akadai sefluorine plasma, hydrochloric acid, kana simbi dzakanyungudutswa kunoita kuti system ive yakavimbika uye ive yakarurama pakuyera.

Uyezve, machubhu esapphire haakurumidzi kupfekwa uye haaori kana akabatwa kwenguva refu nezvidimbu zvine simba rakawanda kana mwaranzi yeUV/IR yakasimba. Kusimba uku kunowedzera hupenyu hwemasensa ethermocouple, zvichideredza mari yekugadzirisa uye nguva yekusashanda kwesystem.

Mashandisirwo Akakura eSapphire Tubes

Kunyange hazvo dziviriro ye thermocouple iri imwe yenzira dzinonyanya kushandiswa, machubhu esapphire anoshandiswawo zvakanyanya mune mamwe maindasitiri epamusoro-soro. Izvi zvinosanganisira:

Kugadziriswa kwePlasma: Machubhu eSapphire anoshanda senzvimbo dzinovharirwa muplasma etching uye deposition systems, uko kusakwanisa kwawo makemikari kunodzivirira kugadzirwa kwezvikamu.
Mwenje wekupisa kwakanyanya: Kujeka kwavo uye kuramba kupisa kunoita kuti vave maenvelopu akakodzera ekubatanidza mwenje weUV, unoonekwa, uye weIR.
Kurapa Mvura uye Kubaya Gasi: Machubhu eSapphire anoshandiswa mumasisitimu anodiwa kudzora mvura kana magasi zvine simba.
Midziyo yekurapa neyemishonga: Nekuda kwehunhu hwadzo husina kusimba mumuviri, machubhu esapphire akachengeteka kushandiswa mumidziyo yakacheneswa kana inoiswa mumiti.
Kuongorora kweSpectroscopy uye Optical: Kujeka kwavo kwemaziso kunobvumira kubatanidzwa zvakanaka mumasisitimu espectroscopy kuti vaone makemikari kana kuti zvinhu zvipenyu.

Muminda yese iyi, machubhu esapphire anopa kugara kwenguva refu kwemuchina uye kuramba makemikari, zvichiita kuti agare kwenguva refu kana achishanda zvakanyanya.

Hunhu Hukuru hweMachubhu eSapphire

Machubhu eSapphire ane musanganiswa usingawanzoonekwi wezvinhu zvinodiwa:

Rudzi rweKutumira Ruzhinji rweOptical: Kubva pa 0.3 μm (UV) kusvika pa 5 μm (IR), yakakodzera kushandiswa kwemasisitimu elaser, kutarisa kwemaziso, uye kuyerwa kwemukati mechinhu.
Kuoma Kwakanyanya: Nekuomarara kweMohs kwe9, safaya haikwarwi nemavanga, inongokundwa nedhaimani chete.
Nzvimbo Yakanyanya Kunyunguduka: Safira inoramba yakagadzikana muchimiro kusvika pa2030°C.
Kufambisa Kunopisa Kunoshamisa: Inopfuudza kupisa zvinobudirira, zvakakosha pakushandiswa kwe thermocouple.
Kugadzikana kweMakemikari: Haipindi acids, alkalis, uye simbi dzakanyungudutswa, kunze kwemunyu unopisa unokonzera kupisa.
Kudzivirira Kwemagetsi Kwakanyanya: Yakanakira kuputira magetsi uye high-voltage insulation.
Kugadzikana kweDimensional: Inochengetedza hunhu hwayo pasi pekumanikidzwa nekupisa kana mutoro wemakanika.

Mabhenefiti ekushandisa Sapphire Tubes paThermocouples

Kubatanidzwa kwemachubhu esafiri muzvikamu zve thermocouple kunounza mabhenefiti akawanda:

Kururama kweSensor Kwakavandudzwa: Kufambiswa kwemhepo kunotsigira kunzwa kupisa nekukurumidza.
Nguva Yesensor Yakawedzerwa: Kusabatwa nengura uye kukweshwa kunodzivirira thermocouple yemukati.
Nguva Yokuzorora Yakaderedzwa: Kukundikana kwemasensa kwakaderera uye zvinodiwa pakugadzirisa zvakare.
Kuchena Kwesisitimu: Kusashanda zvakanaka kwemakemikari kunodzivirira kusvibiswa, izvo zvakakosha pakuchenesa imba.
Mashandiro akawanda: Inobatanidza dziviriro yekupisa nekujeka kwemaziso kuti ishandiswe kaviri mukuona nekuongorora.
