(1) Cov electrode yog me me thiab yooj yim rau nqa. Cov kab noj hniav yog ua los ntawm pob tshab plexiglass los yog ABS raj, uas yog yooj yim los soj ntsuam qhov saturation ntawm tooj liab sulfate tov nyob rau hauv.
(2) Lub peev xwm electrode ruaj khov, thiab cov electrode tsis yooj yim rau polarize.
(3) Lub tshuab hluav taws xob muaj lub neej ua haujlwm ntev, thiab lub hau electrode txuas nrog cov kab noj hniav electrode los ntawm cov ntsia hlau, uas yooj yim rau kev sau cov tshuaj. Ib qho dej tuaj yeem siv tau ntau tshaj ib xyoos.
(4) Cov qauv electrode yog ruaj khov, qhov sib koom ua ke yog corrosion-resistant, qhov to ntawm microporous daim nyias nyias yog qhov tsim nyog, thiab tsis pom cov kua ntws tawm, uas tuaj yeem muab tso rau hauv hnab ris.
Ib tug tag nrho cov khoom siv-lub xeev siv electrode raws li lub siab molecular polymer, cov kua sib txuas uas muaj hlau perchlorate, los yog hlau sulfate, los yog hlau fluoride, los yog silicate. Cov kuab tshuaj ib feem ntawm sab hauv siv electrolyte muaj cawv thiab dej, los yog ib tug polymer los yog copolymer ntawm acrylamide thiab nws derivatives thiab dej. Nws tuaj yeem ua haujlwm ntawm qhov kub txog li 150 degree thiab siab txog 100kg / cm.
Ib tug siv electrode yog ib tug reversible electrode system uas muaj ib tug ruaj khov thiab reproducible reversible electrode tej zaum nyob rau hauv tej yam kev mob. Feem ntau cov kev cai tseem ceeb rau kev siv electrode yog:
(1) The reversibility of the electrode is relatively good, and it is not easy to polarize. This requires the reference electrode to be a reversible electrode with a high exchange current density (>10-5A/cm2). Thaum tam sim no ntws los ntawm electrode tsawg dua 10-7A/cm2, lub electrode tsis polarized. Txawm hais tias qhov loj me me tam sim no ntws rau lub sijhawm luv luv, lub peev xwm tuaj yeem rov qab mus rau tus nqi qub tom qab lub hwj chim raug tua.
(2) Lub peev xwm electrode yog qhov ruaj khov thiab ze rau xoom lub peev xwm, yog li nws tsis yooj yim rau polarized lossis passivated. Tom qab qhov kev siv electrode tau tsim, nws lub peev xwm yuav tsum ruaj khov tom qab sawv rau ob peb hnub.
(3) Lub peev xwm rov tsim dua yog qhov zoo. Lub peev xwm ntawm tib yam siv electrode ua los ntawm cov neeg sib txawv lossis txhua lub sijhawm yuav tsum yog tib yam. Lub peev xwm ntawm txhua qhov siv hluav taws xob tsim tawm txhua lub sijhawm yuav tsum zoo ib yam tom qab kev ruaj ntseg, thiab qhov sib txawv yuav tsum tsawg dua 1 mV.
(4) Qhov kub coefficient yog me me, uas yog, lub peev xwm hloov me ntsis nrog kub. Thiab thaum qhov kub thiab txias rov qab mus rau qhov qub kub, lub peev xwm yuav tsum sai sai rov qab mus rau qhov qub peev txheej.
(5) Kev npaj, siv tiag tiag thiab kev saib xyuas yog yooj yim dua thiab ruaj khov. Cov khoom siv hluav taws xob uas tuaj yeem ua tau raws li qhov xav tau saum toj no suav nrog hydrogen electrode, calomel electrode, mercurous sulfate electrode, mercuric oxide electrode, nyiaj chloride electrode, thiab lwm yam. Feem ntau ntawm cov electrodes no yog hom II electrodes.
