Yuav nrhiav dab tsi thaum siv PH meter/acid meter electrodes
1. Ua ntej ua haujlwm tom ntej tom qab txhua qhov ntsuas thiab ntsuas, cov electrode yuav tsum tau ntxuav nrog dej distilled lossis deionised, thiab tom qab ntawd ntxuav ib zaug ntxiv nrog cov kua ntsuas.
2. Thaum tshem cov PH meter/acid meter electrode sheath, rhiab iav npuas ntawm cov electrode yuav tsum raug zam los ntawm kev sib cuag nrog cov khoom tawv, vim tias kev tawg lossis rub cov plaub hau yuav ua rau cov electrode tsis zoo.
2. Qhov kawg ntawm kev ntsuas, raws sij hawm PH meter / acidity meter electrode tiv thaiv lub tes tsho ntawm lub tes tsho electrode yuav tsum tau muab tso rau ib qho me me ntawm cov kua qaub KCL kom cov electrode npuas ntub dej, tsis txhob ntub dej distilled.
4.PH meter / acidity meter composite electrode sab nraud siv ntxiv rau 3 mol / L potassium chloride tov, cov tshuaj ntxiv tuaj yeem muab ntxiv los ntawm electrode ntawm qhov kawg ntawm lub qhov me me, cov khoom siv hluav taws xob tsis siv, npog nrog roj hmab stopper, los tiv thaiv cov tshuaj ntxiv kom qhuav.
5. PH meter / acidity meter electrode yuav tsum tau ceev kom huv si thiab qhuav ntawm qhov kawg ntawm cov hlau lead, kiag li tiv thaiv cov zis ntawm ob lub voj voog luv luv, txwv tsis pub nws yuav ua rau kev ntsuas qhov tsis raug lossis tsis ua haujlwm.
6.PH 'meter' / acidity meter electrode yuav tsum tau sib phim nrog ntau dua input impedance pH meter Ntau dua lossis sib npaug ntawm 3 × 1011Ω, txhawm rau tswj nws cov yam ntxwv zoo.
7.PH meter / acidity meter electrode yuav tsum tau zam rau lub sijhawm ntev immersed hauv dej distilled, cov ntsiab lus protein thiab acidic fluoride daws.
8. PH meter / acidity meter electrode kom tsis txhob sib cuag nrog cov roj silicone.
9. PH meter / acidity meter electrode tom qab siv mus ntev, xws li txoj kab nqes pom tau tias yuav txo qis me ntsis, cov electrode tuaj yeem tso rau hauv qis kawg ntawm 4% HF hydrofluoric acid (3-5) s, ntxuav nrog dej distilled, thiab ces muab tso rau hauv 0.1 mol / L hydrochloric acid tov, thiaj li hais tias nws yog tshiab, nws yog qhov zoo tshaj los hloov cov electrode.
10. Yog hais tias qhov ntsuas ntsuas muaj cov rhiab qhov muag pom tau yooj yim los yog thaiv cov kua hlws ris ntawm cov khoom siv thiab ua rau cov electrode passivation, yuav muaj kev txo qis hauv txoj kab nqes, cov ntawv nyeem tsis raug tso cai rau qhov tshwm sim. Yog tias qhov tshwm sim tshwm sim, nws yuav tsum tau ua raws li qhov xwm txheej ntawm cov kab mob, nrog rau cov tshuaj ntxuav kom tsim nyog, kom cov electrode tshiab.
Lus Cim 1: Thaum xaiv tus neeg saib xyuas tu, carbon tetrachloride, trichloroethylene, tetrahydrofuran thiab lwm yam tshuaj ntxuav uas tuaj yeem yaj polycarbonate resin tsis tuaj yeem siv, vim tias PH meter / acidometer electrode plhaub yog ua los ntawm polycarbonate resin, uas yooj yim heev rau cov kab mob rhiab heev. iav qhov muag tom qab dissolution, yog li ua rau PH meter / acidometer electrode tsis zoo. Koj tsis tuaj yeem siv cov electrode sib xyaw los ntsuas cov tshuaj saum toj no. Lub sijhawm no, thov siv lub iav plhaub PH meter / acidity meter composite electrode.
Lus Cim 2: PH meter / acidity meter composite electrode siv, qhov teeb meem feem ntau yog cov khoom siv hluav taws xob sab nraud ntawm cov kua hlws ris, cov kua hlws ris ntawm qhov txhaws yog qhov ua rau yuam kev.
