Conductivity yog ib qho kev ntsuas ntawm cov dej muaj peev xwm kom dhau hluav taws xob ntws.Qhov peev xwm no ncaj qha ntsig txog qhov concentration ntawm ions hauv dej
1. Cov khoom siv hluav taws xob no yog los ntawm cov ntsev yaj thiab cov khoom siv tsis zoo xws li alkalis, chlorides, sulfides thiab carbonate compounds.
2. Cov tshuaj uas yaj rau hauv ions kuj hu ua electrolytes.
3. Qhov ntau ions uas tam sim no, qhov conductivity ntawm dej ntau dua.Ib yam li ntawd, tsawg dua ions uas nyob hauv dej, qhov tsawg dua nws yog.Cov dej distilled los yog deionized tuaj yeem ua raws li cov khoom siv hluav taws xob vim nws cov nqi qis heev (yog tias tsis tsim nyog) conductivity nqi.Dej hiav txwv, ntawm qhov tod tes, muaj cov conductivity siab heev.
Ions ua hluav taws xob vim lawv cov nqi zoo thiab tsis zoo
Thaum electrolytes yaj nyob rau hauv dej, lawv muab faib mus rau hauv zoo charged (cation) thiab negatively charged (anion) hais.Raws li cov khoom yaj hauv cov dej sib cais hauv dej, qhov sib npaug ntawm txhua qhov zoo thiab qhov tsis zoo nyob sib npaug.Qhov no txhais tau hais tias txawm tias cov dej conductivity nce nrog cov ions ntxiv, nws tseem muaj hluav taws xob nruab nrab
Conductivity/Resistivityyog ib qho kev ntsuas dav dav siv rau kev ntsuas dej purity, saib xyuas kev rov qab osmosis, kev ntxuav, tswj cov txheej txheem tshuaj, thiab hauv cov dej khib nyiab.Cov txiaj ntsig tau ntseeg tau rau cov ntawv thov sib txawv no nyob ntawm kev xaiv qhov zoo conductivity sensor.Peb phau ntawv qhia pub dawb yog ib qho kev siv dav dav thiab kev cob qhia cov cuab yeej raws li kaum xyoo ntawm kev lag luam kev coj noj coj ua hauv qhov ntsuas no.
Kev coj uayog lub peev xwm ntawm cov khoom siv los ua hluav taws xob tam sim no.Lub hauv paus ntsiab lus los ntawm cov cuab yeej ntsuas kev ua tau zoo yog qhov yooj yim - ob daim hlau muab tso rau hauv cov qauv, muaj peev xwm siv thoob plaws daim hlau (feem ntau yog sine yoj voltage), thiab qhov tam sim no uas dhau los ntawm cov tshuaj yog ntsuas.
