Kev ntxuav tu rau Platinum Rhodium throdocots

1, Ntxuav: Muaj nqis cov hlau thermoco Thermorodles yuav tsum tsis txhob muaj cov tshuaj tsis txaus ntseeg, thiab cov pa roj av khov kho, thiab txuas ntxiv rau lub neej pabcuam. Tsawg tus nqi hlau thermo thermoloples tsis tas yuav tu kom tau txais cov hnub ua haujlwm. Thaum cov hluav taws xob qias neeg yog qias neeg, cov txhuam hlau tuaj yeem siv los tshem tawm cov av thiab oxide nplai. Cov cuab yeej thermocoples tsis tas yuav tu.

2, Acid Ntxuav

Cawv yog qhov kev tshem tawm ntawm cov tshuaj sib xyaw thiab cov saib xyuas cov tshuaj oxides hauv lub npe ntawm cov hluav taws xob thermoelectric.

1. Cov kua qaub ua rau platinum Rhodium series thermocofle yog li ntawm li 30% tshuaj lom neeg rau 1 teev lossis hau li 15 feeb. Tom qab coj nws tawm, nws yog boiled ob peb zaug nrog dej distilled kom txog thaum cov acidity yog tshem tawm.

2. Tus txheej txheem pickling rau platinum riboco series thermocouple rau 1 feeb, coj nws ntau zaus nrog dej distilled los tshem tawm acidity.

3. Acid ntxuav txoj kev rau kub platinum thermocouples: ua ntej ntxuav, tshem tawm cov khov clamp ntawm thermocouple thiab txiav tawm ntawm lub taub hau thermocouple. Nres acid ntxuav kom paub qhov txawv ntawm platinum xaim thiab kub hlau. So li cov platinum xaim hauv 30% daws ntawm koj cov tshuaj huv si acid lossis nitric acid rau 1 teev, tom qab ntawd coj nws ob peb zaug nrog dej distilled los tshem tawm acidity. Raus cov xaim kub hauv cov tshuaj kub muaj ntawm 100g dej, 15g ntawm ntsev rau 2kg ntawm 1kg ntawm dej kub thiab 25g ntawm sodium bicarbonate.

Saib xyuas yuav tsum tau them nyiaj thaum cheemping acid ntxuav ntawm thermocouples:

1. Cov concentration ntawm 30% {2}}}}% acid yog hais txog feem pua ​​ntawm cov huab fab;

2. Txhawm rau tswj hwm kev nyab xeeb, dej distilled yuav tsum tau hliv rau hauv lub beaker ua ntej ntxiv cov kua qaub thaum npaj ua ntej npaj.

3, Berax Ntxuav:

Borax yog ib qho tsis muaj xim thiab pob tshab siv lead ua uas cov dehydrates los ua cov sodium lub sijhawm thaum ua kom sov li 400 degree. Lub ntsiab lus melting ntawm SRRACATION yog tsawg heev, melting mus rau hauv lub iav iav ntawm 878 degree. Nws tus kheej yog sodium borate thiab boron gangue.

Molten Borax muaj peev xwm yaj hlau oxides thiab ua ib khob zoo li cov compound uas yog ib txwm ruaj khov nrog cov oxide, tso cai rau kev tshem tawm ntawm cov hlau oxide los ntawm lub thermoelectric electrode. Borax yog cov pa tsis zoo rau cov hlau. Cov qauv no yog siv Borax, uas muaj lub peev xwm los rau yaj hlau oxides ntawm tsawg kub, rau kev txwv tsis pub muaj cov khoom muaj nqis cov khoom muaj nqis cov khoom muaj nqi thermocoalles.

Siv thermorochples xav tau kom nres borax Scrubbing tom qab siv cov kua qaub, thaum tshiab ua thermocouples tsis tas yuav tsum tsis txhob tsum borax txhuam.

Thaum tu, lub thermoelectric electrode yuav tsum tau txuas ntxiv thiab qhov siv kawg yuav tsum tau dai rau ntawm kev tu bracket nrog lub platinum nuv. Lub kaum sab xis ntawm ob daim ntawv hluav taws xob yuav tsum khaws cia me me.

Maj mam kho cov tswv yim tam sim no, thov tam sim no ntawm 10A rau lub platinum throdium 6 PlatinoPle kom ua kom sov kub rau (1100 ~ 1150) degree. Siv kev siv tshuaj Browon ntshiab nyob ze rau cov lus kawg ntawm lub thermoelectric electrode rau yaj lub borax rau cov tee dej, uas ntws tawm ntawm cov hluav taws xob. Tom qab ntau cov kev ntxuav, cov thermoelectric electrode yuav ua rau muaj xim hlau ci. Yog tias tseem muaj qhov ua rau muaj kev sib daj sib daj ua rau lub thermoelectric electrode tom qab rov qab ntxuav (ntau dua 3 zaug tsis xwm yeem thiab yuav tsis raug kuaj xyuas kom qhia tau. Tom qab ntxuav nrog borax, qhov tam sim no yuav tsum maj mam txo thiab lub zog hluav taws xob yuav tsum tau thaiv. Lub thermocouple yuav tsum tau muab tshem tawm thiab coiled rau hauv lub voj voog sib haum. Nws yuav tsum tau npau npau npau hauv dej distilled kom txog thaum txhua lub khob iav ntawm cov electrode melted.

Lub Platinum Rhodium thermocouple tsuas yog yuav tsum tsis txhob nres lub platinum xaim raws li cov txheej txheem saum toj no, thiab tam sim no thov yog 10. Tsis tas yuav tsum ntxuav lub Rhodium hlau nrog Borax.

Cov kev ceev faj:

1. Thermoelectric siv hluav taws xob thiab platinum hooks yuav tsum muaj kev sib ntaus sib tua zoo heev;

2. Thaum dai cov ntsiav tshuaj kub, lub kaum sab xis yuav tsum cia cov hom phiaj me me, nrog rau kev ua kom muaj zog thiab ua rau nws yooj yim borft gorax kom ntws mus hauv cov electrode;

3. Cov cua sov yuav tsum nruj me ntsis tswj tau. Yog tias qhov ntsuas kub tsawg dhau, cov belted borax yog tus to solidification, uas cuam tshuam rau cov txheej txheem ntxuav; Yog tias qhov ntsuas kub siab dhau, lub thermoelectric nplej yuav nyob rau yav tsaus ntuj tau ntau xyoo, ua rau muaj kev txo qis hauv lawv lifespan.
