Cov ntaub ntawv hais txog roj teeb Passivation

Ntau yam ntawm Netvox li yog siv los ntawm 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) roj teeb uas muaj ntau yam advantages suav nrog tus nqi qis tus kheej tawm thiab siab zog ceev.
Txawm li cas los xij, thawj cov roj teeb lithium zoo li Li-SOCl2 roj teeb yuav tsim cov txheej txheem passivation raws li cov tshuaj tiv thaiv ntawm lithium anode thiab thionyl chloride yog tias lawv khaws cia rau lub sijhawm ntev lossis yog tias qhov ntsuas kub siab dhau lawm. Cov txheej txheem lithium chloride no tiv thaiv tus kheej tawm sai sai los ntawm cov tshuaj tiv thaiv txuas ntxiv ntawm lithium thiab thionyl chloride, tab sis roj teeb passivation kuj tseem tuaj yeem ua rau vol.tage ncua sij hawm thaum cov roj teeb tau muab tso rau hauv kev ua haujlwm, thiab peb cov khoom siv yuav tsis ua haujlwm raug rau qhov xwm txheej no.
Yog li ntawd, thov nco ntsoov cov roj teeb los ntawm cov neeg muag khoom txhim khu kev qha, thiab cov roj teeb yuav tsum tau tsim nyob rau hauv peb lub hlis dhau los.
Yog tias ntsib qhov teeb meem ntawm roj teeb passivation, cov neeg siv tuaj yeem qhib lub roj teeb kom tshem tawm cov roj teeb hysteresis.

Txhawm rau txiav txim siab seb lub roj teeb xav tau kev ua haujlwm

Txuas lub roj teeb ER14505 tshiab rau 68ohm resistor nyob rau hauv parallel, thiab xyuas cov voltage ntawm lub voj voog.
Yog voltage yog qis dua 3.3V, nws txhais tau tias lub roj teeb yuav tsum tau ua kom.

Yuav ua li cas qhib lub roj teeb

ib. Txuas lub roj teeb rau 68ohm resistor nyob rau hauv parallel
b. Khaws qhov kev sib txuas rau 6 ~ 8 feeb
c. Lub voltage ntawm Circuit Court yuav tsum yog ≧3.3V

Cov Lus Qhia Tseem Ceeb Saib Xyuas

Ua tib zoo saib xyuas cov hauv qab no txhawm rau ua tiav kev saib xyuas zoo tshaj plaws ntawm cov khoom:

• Khaws lub cuab yeej kom qhuav. Los nag, dej noo, lossis cov kua dej yuav muaj cov ntxhia thiab yog li ua rau cov hluav taws xob hluav taws xob. Yog tias lub cuab yeej ntub dej, thov kom qhuav tag.
• Tsis txhob siv lossis khaws cov cuab yeej hauv qhov chaw muaj plua plav lossis qias neeg. Nws yuav ua kom puas nws qhov khoom tshem tawm thiab cov khoom siv hluav taws xob.
• Tsis txhob khaws lub cuab yeej nyob hauv qhov kub ntau dhau. Qhov kub siab tuaj yeem ua lub neej luv ntawm cov khoom siv hluav taws xob, rhuav tshem cov roj teeb, thiab deform lossis yaj qee qhov yas.
• Tsis txhob khaws cov cuab yeej rau hauv qhov chaw txias heev. Txwv tsis pub, thaum kub nce mus rau qhov kub thiab txias, noo noo yuav tsim sab hauv, uas yuav ua kom puas lub rooj tsavxwm.
• Tsis txhob muab pov, khob lossis co lub cuab yeej. Kev tuav tsis zoo ntawm cov cuab yeej tuaj yeem rhuav tshem cov vaj huam sib luag sab hauv thiab cov qauv tsim.
• Tsis txhob ntxuav lub cuab yeej nrog cov tshuaj muaj zog, cov tshuaj detergents lossis cov tshuaj detergents.
• Tsis txhob siv lub cuab yeej nrog cov xim. Smudges yuav thaiv hauv lub cuab yeej thiab cuam tshuam rau kev ua haujlwm.
• Tsis txhob muab lub roj teeb tso rau hauv qhov hluav taws kub, lossis lub roj teeb yuav tawg. Cov roj teeb puas tseem tuaj yeem tawg.

Txhua qhov saum toj no siv rau koj lub cuab yeej, roj teeb thiab khoom siv ntxiv. Yog tias cov cuab yeej siv tsis ua haujlwm zoo, thov coj nws mus rau qhov chaw tso cai muab kev pab kho kom ze tshaj plaws.
