Vim li cas Sapphire Tubes thiaj muaj kev ua tau zoo heev?

Cov raj sapphire paub txog lawv lub peev xwm los tswj kev ruaj khov ntawm cov qauv thiab kev ua haujlwm hauv qab kev ntxhov siab ntawm lub cev thiab tshuaj lom neeg. Hauv cov tshuab siab, lawv siv ua ob qho tib si cov thawv ntim khoom thiab cov qhov rai soj ntsuam, muab ib puag ncig ruaj ntseg thiab inert rau kev soj ntsuam cov kua thiab cov pa roj. Vim lawv lub zog compressive siab thiab kev tiv thaiv khawb, cov raj sapphire kuj tseem haum rau cov chaw uas muaj kev cuam tshuam loj heev lossis kev hloov pauv kub ntau zaus.

Cov raj no yog qhov tshwj xeeb hauv lawv lub peev xwm los ua haujlwm ntawm qhov kub txog li 2000 ° C yam tsis muaj softening lossis deforming. Tsis zoo li ntau lwm yam khoom siv ceramic lossis iav, sapphire khaws nws cov duab thiab cov khoom siv kho tshuab txawm tias nyob rau hauv qhov kub siab. Qhov kev ua tau zoo no yog qhov tseem ceeb hauv cov ntawv thov uas qhov sib xws ntawm lub cev yog qhov tseem ceeb rau kev sib khi, rwb thaiv tsev, lossis kev sib dhos - xws li hauv cov thermocouple tsev nyob.

Lawv qhov kev pom tseeb ntawm lub teeb pom kev thoob plaws ntau qhov spectrum—txij li ultraviolet (0.3 μm) mus txog rau infrared (5 μm)—ntxiv lwm txheej ntawm kev ua haujlwm. Qhov feature no tso cai rau cov raj sapphire tsis yog tsuas yog ua haujlwm ua cov khoom siv xwb tab sis kuj txhawb nqa cov kab ke optical rau kev saib xyuas lub sijhawm tiag tiag thiab kev ntsuas laser.

Cov raj Sapphire hauv Kev Tiv Thaiv Thermocouple

Cov thermocouples yog cov ntsuas kub tseem ceeb uas siv thoob plaws kev lag luam xws li aerospace thiab metallurgy mus rau semiconductor fabrication thiab tshuaj ua haujlwm. Txawm li cas los xij, thermocouples yog cov cuab yeej rhiab heev uas tuaj yeem lwj sai thaum raug ncaj qha rau cov pa roj reactive, plasma ib puag ncig, lossis cov voj voog cua sov / txias sai. Txhawm rau tiv thaiv cov teeb meem no, cov raj sapphire ua haujlwm ua cov sheaths tiv thaiv zoo tagnrho rau thermocouples.

Qhov kev ua kom sov ntawm sapphire ua kom muaj kev hloov pauv cua sov sai thiab raug rau lub thermocouple hauv lub raj, tso cai rau kev saib xyuas qhov kub thiab txias tiag tiag thaum tiv thaiv lub sensor los ntawm cov khoom corrosive, kev puas tsuaj ntawm lub tshuab, thiab kev poob siab thermal. Qhov sib npaug ntawm kev rwb thaiv tsev thiab kev coj ua no ua rau cov raj sapphire tshwj xeeb rau kev tiv thaiv thermocouple hauv cov chaw tsis zoo.

Tsis tas li ntawd xwb, sapphire txoj kev tsis muaj tshuaj lom neeg tiv thaiv kev ua qias tuaj ntawm cov txheej txheem ib puag ncig. Qhov no tseem ceeb heev rau cov ntawv thov siab-purity xws li semiconductor wafer processing, kev kho mob sterilization systems, lossis high-vacuum thermal chambers. Qhov tsis muaj kev sib xyaw ntawm sapphire thiab cov tshuaj lom neeg xws li fluorine plasma, hydrochloric acid, lossis molten hlau ua kom ntseeg tau tias qhov system ntseeg tau thiab ntsuas qhov tseeb.

Ntxiv mus, cov raj sapphire tiv taus kev hnav thiab tsis lwj thaum raug rau cov khoom me me lossis cov hluav taws xob UV / IR ntev. Qhov kev ruaj khov no ua rau lub neej ntawm cov thermocouple sensors ntev dua, txo cov nqi kho thiab lub sijhawm tsis ua haujlwm ntawm lub kaw lus.

Cov Ntawv Thov Dav Dav ntawm Sapphire Tubes

Txawm hais tias kev tiv thaiv thermocouple yog ib qho ntawm cov ntawv thov sawv cev, cov raj sapphire kuj siv dav hauv lwm cov thev naus laus zis siab thiab kev lag luam. Cov no suav nrog:
