Dab tsi yog pH ua ke electrode?
Ib qho hluav taws xob uas sib txuas nrog pH iav electrode thiab siv hluav taws xob siv hu ua pH electrode. Cov ntaub ntawv nrog lub plhaub yas hu ua yas plhaub pH sib xyaw electrode. Ib qho nrog iav plhaub yog hu ua iav pH sib xyaw electrode. Qhov txiaj ntsig loj tshaj plaws ntawm cov khoom siv hluav taws xob sib xyaw yog tias nws muab ob qho tib si rau hauv ib qho thiab siv tau yooj yim. Cov qauv ntawm cov khoom siv hluav taws xob pH feem ntau yog tsim los ntawm cov qhov muag teev hluav taws xob, cov iav txhawb nqa rods, cov khoom siv hluav taws xob sab hauv, cov kev daws teeb meem sab hauv, cov plhaub, cov khoom siv hluav taws xob sab nraud, cov kev siv sab nraud, cov kua junctions, electrode caps, electrode wires, sockets, thiab lwm yam.
⑴ Electrode noob: Nws yog ua los ntawm molten lithium iav nrog hydrogen muaj nuj nqi thiab yog spherical nyob rau hauv cov duab, nrog ib tug zaj duab xis thickness ntawm txog 0.1-0.2 hli thiab ib tug kuj muaj nuj nqis ntawm<250 megohms (25°C).
⑵ Lub raj mis txhawb nqa: nws yog lub iav raj lub cev uas txhawb nqa lub teeb hluav taws xob. Nws yog ua los ntawm cov iav txhuas nrog cov hluav taws xob zoo heev, thiab nws cov coefficient nthuav dav yuav tsum ua raws li cov iav electrode teeb.
(3) Sab hauv siv electrode: Nws yog nyiaj / nyiaj chloride electrode, lub luag haujlwm tseem ceeb yog coj tawm lub peev xwm electrode, uas yuav tsum muaj peev xwm ruaj khov thiab me me qhov kub thiab txias coefficient.
(4) Cov tshuaj siv sab hauv: Cov tshuaj siv sab hauv nrog xoom lub peev xwm ntawm 7pH yog cov tshuaj sib xyaw ntawm nruab nrab phosphate thiab potassium chloride. Cov iav electrode thiab cov ntaub ntawv siv electrode tsim lub roj teeb los tsim kom muaj pH tus nqi ntawm xoom lub peev xwm, uas feem ntau yog nyob ntawm pH ntawm tus nqi siv tshuaj sab hauv thiab chloride ion concentration.
⑸ Electrode molded case: Cov ntaub ntawv electrode molded yog lub plhaub uas txhawb cov iav electrode thiab cov kua hlws ris, thiab tuav cov kev siv sab nraud, thiab yog molded los ntawm PPS yas siab.
⑹ Sab nrauv siv electrode: Nws yog nyiaj / nyiaj chloride electrode. Nws txoj haujlwm yog muab thiab tswj xyuas qhov muaj peev xwm siv tau ruaj khov, uas yuav tsum muaj peev xwm ruaj khov, zoo rov tsim dua tshiab, thiab qhov kub me me coefficient.
⑺ Kev siv sab nraud: 3.3mol / L potassium chloride gel electrolyte, tsis yooj yim plam, tsis tas yuav ntxiv.
⑻Sand core kua hlws ris: Cov kua hlws ris yog qhov sib txuas uas txuas cov kev siv sab nraud thiab cov kev ntsuas ntsuas, thiab yuav tsum muaj kev nkag mus ruaj khov.
⑼ Electrode hlau: Nws yog cov hlau tsis tshua muaj suab nrov shielded hlau, cov tub ntxhais sab hauv txuas nrog cov khoom siv hluav taws xob sab hauv, thiab cov txheej thaiv thaiv tau txuas nrog rau sab nraud siv electrode.
