Kev siv thiab kev saib xyuas ntawm lub chaw kuaj pH meter electrodes
1. Ua ntej kuaj cov qauv slurry, muab tso rau hauv qhov chaw kuaj pH meter electrode lub taub hau rau hauv cov qauv sib xyaw ua ke, co lub thawv nqa cov qauv kom cov pH meter electrode tag nrho hu rau cov qauv, thiab tom qab ntawd sawv ntsug rau kev sim; Tsis txhob tuav lub pH meter electrode thiab do hauv cov qauv ntsuas kom tsis txhob muaj kev puas tsuaj rau pH meter electrode.
2. Tom qab txhua qhov kev sim, pH meter electrodes yuav tsum tau muab yaug kom huv si nrog dej distilled, thiab tom qab ntawd qhuav nrog daim ntawv mos. Daim ntawv tawv yuav tsum tsis txhob siv los so pH meter electrode spherical xeem lub taub hau kom tsis txhob muaj kev puas tsuaj rau pH meter electrodes.
3. Lub rhiab pH meter iav npuas hauv cov yas tiv thaiv yuav tsum tsis txhob kov cov khoom tawv thiab yuav tsum tsis txhob muab so. Txhua qhov kev puas tsuaj lossis khawb yuav ua rau pH meter electrode ua tsis tiav.
4. Tom qab siv lub ntsuas pH hauv chav kuaj, nws yog ib qho tsim nyog los ntub cov pH meter electrode kuaj lub taub hau hauv KC1 (3mol · L-1) tiv thaiv kev daws teeb meem. Feem ntau, yog tias cov yeeb yaj kiab rhiab ntawm pH meter electrode kuaj lub taub hau dries li ob peb teev, nws yuav ua rau muaj kev puas tsuaj rau pH meter electrode.
5. Cov khoom sib xyaw PH electrode yuav tsum tsis txhob muab tso rau hauv cov dej distilled mus ntev, kua protein, los yog acidic fluoride tov, thiab tiv thaiv kev sib cuag nrog cov organic silicon roj.
6. Feem ntau cov pH sib xyaw electrodes muaj qhov nominal khiav hauj lwm kub ntawm 0-70 degree thiab yuav tsum tau zam los ntawm overheating.
7. Tom qab siv lub sijhawm ntev ntawm lub chaw kuaj pH meter electrode, yog tias pom qhov txo qis hauv gradient, feem ntau nws tuaj yeem tsau rau hauv 0.1% HC1 tov rau 12 teev, lossis soaked hauv 4% HF acid. rau 3-58 teev, ces ntxuav nrog dej distilled, thiab ces tsau rau hauv KC1 kom rejuvenate nws; Yog tias nws kis tau los ntawm cov khoom xws li roj, resin, thiab cov protein, cov khoom siv sib txawv yuav tsum raug xaiv raws li cov khoom ua paug rau kev ntxuav.
