Yuav siv pH ua ke electrode li cas?
(1) Yuav tsum tsis muaj cua npuas nyob rau pem hauv ntej kawg ntawm lub teeb. Yog tias muaj cua npuas, lawv yuav tsum muab pov tseg nrog kev quab yuam.
(2) Tom qab cov electrode raug tshem tawm ntawm lub raj mis ntub dej, nws yuav tsum tau shaken hauv dej deionized thiab shaken qhuav. Tsis txhob so lub teeb nrog cov ntaub so ntswg. Txwv tsis pub, tus nqi hluav taws xob electrostatic induction yuav raug xa mus rau lub iav daim nyias nyias, uas yuav ncua sij hawm rau lub peev xwm kom ruaj khov. Ib txoj hauv kev zoo dua yog Yaug cov electrode nrog cov tshuaj ntsuam xyuas.
(3) Tom qab cov pH sib xyaw electrode tau muab tso rau hauv cov tshuaj uas yuav tsum tau ntsuas, do thiab co nws ob peb zaug ua ntej tso nws. Qhov no yuav ua kom cov lus teb ntawm electrode. Tshwj xeeb tshaj yog thaum siv cov ntaub ntawv yas pH composite electrode, lub nplawm thiab co yuav tsum muaj zog dua, vim tias yuav muaj kab noj me me ntawm lub teeb thiab cov ntaub ntawv yas. Tom qab cov electrode tau muab tso rau hauv qhov kev daws teeb meem, qee zaum cov roj hauv cov kab noj hniav yuav tsis tawm hauv lub sijhawm thiab cov npuas yuav tsim tawm, ua rau lub kaum sab xis ntawm cov npuas lossis cov kua sib txuas thiab cov tshuaj tsis zoo, yog li muaj zog nplawm thiab co. yuav tsum tau tshem tawm cov npuas.
(4) Tom qab kuaj xyuas hauv cov qauv viscous, cov electrode yuav tsum tau yaug nrog dej deionized ntau zaus kom tshem tawm cov qauv ua raws li cov iav zaj duab xis. Qee lub sij hawm nws yuav tsum tau ntxuav cov qauv nrog lwm cov reagents ua ntej, tom qab ntawd ntxuav cov kuab tshuaj nrog dej, thiab tom qab ntawd muab tso rau hauv cov kua dej kom ua kom muaj zog.
(5) Tsis txhob sib cuag nrog cov kua qaub uas muaj zog, alkalis lossis corrosive daws. Yog tias koj sim cov kev daws teeb meem zoo li no, koj yuav tsum txo lub sijhawm immersion thiab ntxuav lawv kom zoo tom qab siv.
(6) Tsis txhob siv rau hauv lub cev qhuav dej xws li ethanol thiab concentrated sulfuric acid, uas yuav ua rau cov hydrated gel txheej rau ntawm qhov muag teeb.
(7) Cov khoom siv plhaub ntawm cov yas pH puas electrode yog polycarbonate yas (PC). PC yas yuav yaj nyob rau hauv ib co kuab tshuaj, xws li carbon tetrachloride, trichlorethylene, tetrahydrofuran, thiab lwm yam. Yog hais tias cov saum toj no cov kuab tshuaj muaj nyob rau hauv lub xeem, nws yuav Electrode plhaub, nyob rau hauv cov ntaub ntawv no, ib tug pH composite electrode nrog lub iav plhaub yuav tsum tau siv xwb. .
