Cov Electrodes thiab daim ntawv thov teb

Edit: Shaanxi Elade tshiab khoom Technology Co., Ltd    Date: Jun 12, 2016

Tus electrode yog ib tug neeg xyuas pib uas kis tau ib qho chaw hluav taws xob ntawm nruab nrab ib mus rau lwm leej, feem ntau yog los ntawm ib qhov fais fab tuag ib tug ntaus los yog khoom tawg yooj yim. Nws yuav siv ntau hom sib txawv, xws li ib tus hlau, ib phaj los yog ib tug pas nrig, thiab yog feem ntau yog ua los ntawm hlau, tooj, nyiaj, txhuas, los zinc, tiam sis yuav kuj tau ua los ntawm ib yam khoom uas tsis-nws yog xim hlau uas qha kuas ua txhua hluav taws xob, xws li graphite.


Tus electrode hauv lub electrochemical ntawm tes yog hu ua tus anode los yog ib tug cathode. Tus anode no txhais tias yog tus electrode uas electrons tawm tus ntawm tes thiab oxidation no tshwm sim, thiab lub cathode li cov electrode uas electrons sau rau ntawm tes thiab yuav txo tau kev mob. Txhua electrode yuav muaj lub anode los yog cov cathode li cov uas tam sim no mus txog rau ntawm tes. Ib bipolar electrode yog ib qho electrode uas tso cai raws li tus anode hauv ib ntawm tes thiab tus cathode ntawm lwm ntawm tes.


Anodes thiab Cathodes


Tus ib tam sim no mus ncaj (DC), electrodes officers tuaj, thiab paub li anodes thiab cathodes. Rau ib qhov DC, tus cathode txhais tias tus uas los ntawm cov chaw yoojyim electrode, thiab anode cov thaum twg nws rov kis. Rau lwm yam uas muaj keeb kwm zoo dua qhov hluav taws xob hauv Circuit Court ib kev, mas yog convention, depicted li mus tsham zoo los tsis zoo, kom nws pom raws li ib tug ndlwg zoo xwb tawm los ntawm lub cathode, thiab rau lub anode. Ib qho hluav taws xob tamsis no, tsis tas li ntawd, muaj ib tug txaus cov pob me me cuam them raws cua ces hu ua electrons, vim li ntawd no txaus yog tau khiav hauv kev. Nyob hauv cov ntsiab lus teb no, nws tseem zoo dua zaum ib tsab ntawd positive thiab negative terminals sa.


Electrolysis

Kom tau ib tug zauv caij, ib compound ionic ntawm cov caij ntawd yuav tau electrolyzed. Ib qho piv txwv yog qhov sodium hlau molten ntsev, lossis sodium chloride. Thaum rau cov tsev uas tam sim no, zoo them sodium ions no attracted electrode tsis zoo, los yog cathode uas lawv nce electrons, tug sodium hlau. Cuam them chloride ions muaj attracted los anode, uas lawv poob electrons, txoj kev ua pa tshuaj chlorine, uas kuj yuav sau ua ib by-product.


Electroplating

Nyob hauv txoj kev no, lub nruas hlau no coated nrog lwm hlau rau kom nws ua hauj corrosion los yog zog. Tus tsav haus dejcawv yuav tsum coated tas li tus cathode hauv ib txoj kev electrolysis los raus hauv tov ib soluble compound txog tus hlau uas yuav tsim cov txheej, nrog cov anode kuj yog ua los ntawm cov hlau no. Thaum faib cov chaw, txoj hlau ions los ntawm cov tshuaj attracted mus rau cathode, thiab cov tsim ib deposit rau nws. Raws li tus ions hauv hais haum siv, lawv yuav los hloov cov ions uas tsim los ntawm cov anode. Qee zaum, cov qhov anode yog tsim los ntawm ib yam khoom uas tsis siv mus; hom no, cov hlau ions raug muab hloov ua topping tau cov kua.



Pab electrodes

Electrodes mus rau kev kho mob, xws li EEG (rau teev lub hlwb kev ua), ECG (teev lub plawv neeg ntaus), ECT (hluav taws xob hlwb stimulation), defibrillator (teev thiab delivering stimulation mob);

Electrodes rau cov hom kev kawm electrophysiology hauv kev tshawb biomedical;

Electrodes rau cov electrolysis ;

Electrodes rau cov electroplating ;

Electrodes cathodic tiv thaiv .
