Industrial pH meter rau ntsuas thiab saib xyuas cov dej ntws
1. Cov khoom tseem ceeb ntawm cov tshuaj moisturizing
Cov ntsiab lus tseem ceeb ntawm cov kav dej yog cov buffering agents, preservatives, phaj protectors, desiccants, algae inhibitors, thiab lwm yam. Ntawm lawv, buffering agents muaj qhov cuam tshuam loj tshaj plaws ntawm pH tus nqi ntawm cov ciav dej.
2. Kev ua haujlwm ntawm tsis muaj
a) Kev ua haujlwm ntawm qhov tsis yog txhawm rau txhawm rau cov kua qaub ntawm cov kav dej, vim tias cov kais dej feem ntau nruab nrab. Txhawm rau kom ua tiav qhov pH tus nqi (5-6) rau kev luam ntawv ib txwm, cov kua qaub yuav tsum tau muab ntxiv rau cov dej ntws kom tswj tau cov kua qaub tsis muaj zog. Cov carbonates hauv dej yuav hnov mob nrog cov kua qaub ntxiv, ua rau nce pH tus nqi. Nyob rau lub sijhawm no, yuav tsum tau ntxiv qhov tsis sib xws kom tswj tau tus nqi pH ruaj khov ntawm cov kav dej.
b) Nyob rau tib lub sijhawm, cov neeg ua haujlwm buffering kuj tseem muaj txiaj ntsig zoo rau kev txo qis kev cuam tshuam ntawm cov tshuaj ntxuav thiab lwm yam ntawm cov dej ntws. Tab sis raws li tus nqi ntawm qhov tsis ntxiv hloov pauv, tus nqi pH ntawm cov kav dej yuav hloov pauv ntau. Kev sib ntxiv tsis tsim nyog kuj tuaj yeem cuam tshuam rau lub neej kev pabcuam ntawm cov tshuab luam ntawv thiab cuam tshuam cov number case kom qhuav, tshwj xeeb tshaj yog rau cov inks uas muaj cov xim hlau.
3. Kev cuam tshuam ntawm dej ntawm tus nqi pH
Dej kuj tseem muaj feem cuam tshuam rau pH tus nqi ntawm cov kav dej. Cov dej zoo ntawm cov kais dej tuaj yeem yog mos lossis tawv. Cov dej uas muaj cov ntsiab lus hlau cation siab yog cov dej nyuaj, thaum cov dej uas muaj cov ntsiab lus anion siab yog cov dej mos. Lub siab hardness ntawm dej yuav ua rau kom pH tus nqi ntawm cov kav dej. Thaum npaj cov tshuaj moisturizing, cov dej softness thiab hardness yuav tsum tau kho raws li cov kev xav tau tiag tiag, nrog rau qhov haum ntawm 10 degree dH. Nws tseem yuav tsum tau muab sau tseg tias kev hloov hauv dej kub tuaj yeem cuam tshuam qhov concentration ntawm ions hauv dej. Yog li kev tswj qhov hardness thiab kub ntawm cov dej yog tsim nyog kom ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov kav dej.
Qhov tsim nyog ntawm kev siv industrial conductivity meters
Tswj conductivity kom ruaj khov pH tus nqi
Txhawm rau kom ntseeg tau tias tus nqi pH ruaj khov ntawm cov ciav dej, ib txoj hauv kev zoo tshaj plaws yog los saib xyuas cov dej ntws ntawm cov ciav dej thaum tswj cov nyiaj tsis ntxiv thiab qhov tawv ntawm cov dej.
Conductivity meter ntsuas thiab saib xyuas cov kua roj lubrication
Raws li qhov concentration ntawm cov dej phwj tuaj nce, qhov hardness ntawm cov dej thiab qhov kub thiab txias ntawm cov dej hloov, cov conductivity ntawm tus ciav dej yuav nce, thiab tus nqi pH yuav txo; Ntawm qhov tsis sib xws, yog tias haus cawv ntxiv rau hauv qhov dej, qhov kev coj ua ntawm cov kav dej txo qis thiab pH tus nqi nce. Tom qab kuaj nrog lub ntsuas ntsuas kev lag luam, feem ntau ntawm cov kav dej yuav tsum tau tswj nyob rau hauv (1400 ± 200) μ S / cm, tab sis vim yog cov hmoov av, number case, thiab lwm yam impurities, conductivity yog nyob ib ncig ntawm 800 μ S. / cm ~ 2000 μ Tsis pub dhau s / cm, nws kuj tau tso cai, tab sis thaum lub roj nplaum zoo li muaj paug, nws yuav tsum tau kho dua tshiab.
