Qhov sib txawv tseem ceeb ntawm mercury cell thiab diaphragm cell yog tias mercury cell feem ntau xav tau qhov hluav taws xob ntau dua thiab lub zog ntau dua piv rau diaphragm cell.
Peb tuaj yeem siv mercury hlwb, diaphragm hlwb, thiab cov cell membrane los tsim cov tshuaj chlorine thiab caustic soda ntawm kev lag luam. Hauv txhua txoj kev, lub hauv paus yog electrolyze sodium chloride tov.
Mercury Cell yog dab tsi?
Ib lub xov tooj ntawm tes lossis mercury roj teeb yog lub roj teeb hluav taws xob uas tsis tuaj yeem them rov qab. Peb tuaj yeem categorize nws ua lub xov tooj tseem ceeb thiab tseem hu ua mercuric oxide roj teeb, khawm cell, thiab Ruben-Mallory. Feem ntau, lub roj teeb mercury siv cov tshuaj tiv thaiv ntawm mercuric oxide thiab zinc electrodes hauv alkaline electrolyte. Qhov hluav taws xob ntawm mercury cell yog 1.35 volts thaum qhov tawm ntawm lub xov tooj ntawm tes tseem ua haujlwm tas li. Ntawm no, lub peev xwm ntau dua li zinc-carbon roj teeb ntawm tib qhov loj. Txawm tias yav dhau los, cov roj teeb no tau siv los ua lub pob khawm rau cov saib, cov khoom siv hnov lus, lub koob yees duab, thiab lub tshuab xam zauv.
Lub cathode ntawm mercury cell feem ntau yog cov ntshiab mercury (II) oxide los yog sib xyaw ntawm mercury (II) oxide nrog manganese dioxide. Txawm li cas los xij, mercuric oxide tsis yog tus coj. Yog li ntawd, peb yuav tsum sib tov graphite nrog nws los tiv thaiv kev sau ntawm mercury rau hauv cov tee loj. Tsis tas li ntawd, lub anode ntawm lub xovtooj ntawm no yog tsim los ntawm zinc, thiab nws cais tawm ntawm cathode ntawm ib txheej ntawm daim ntawv ntawm cov khoom ntxeem tau uas yog soaked nrog electrolyte. Peb hu qhov no tus choj ntsev. Ntxiv mus, cov electrolyte ntawm mercury cell yog sodium hydroxide lossis potassium hydroxide.
Thaum xav txog cov yam ntxwv hluav taws xob ntawm lub xov tooj mercury, yog tias cov cathode yog mercuric oxide, cov hlwb no muaj qhov nkhaus tawm ncaj qha uas tuaj yeem tuav qhov voltage ntawm 1.35 V mus txog rau 5% kawg ntawm lub neej ntawm tes. Ntxiv mus, qhov voltage tseem nyob hauv 1% rau ntau xyoo ntawm lub teeb load. Ntawm qhov tod tes, mercury hlwb nrog cov mercuric oxide thiab manganese dioxide cathode muaj 1.4 V tso zis thiab ib tug ntau sloped paug nkhaus.
Diaphragm Cell yog dab tsi?
Ib lub diaphragm cell yog ib lub xovtooj ntawm electrolytic muaj txiaj ntsig hauv kev tsim cov sodium hydroxide thiab chlorine los ntawm sodium chloride brine. Lub diaphragm ntawm tes cuam tshuam nrog cov dej ntws ntawm cov dej brine (uas tau nkag mus rau hauv lub anode) los ntawm thaj chaw anode mus rau thaj tsam cathode ntawm permeable diaphragm. Hauv cov txheej txheem no, thaj chaw anode raug cais tawm ntawm thaj chaw cathode ntawm ib qho permeable diaphragm. Txawm li cas los xij, lub diaphragm cell qhia tau hais tias tsis muaj zog ua haujlwm, tsis muaj kev phooj ywg ib puag ncig, thiab tsis muaj purity ntawm cov khoom. Nyob rau hauv kev sib piv rau lub cell no, lub membrane cell yog ib tug optimized txheej txheem.
Feem ntau, lub diaphragm cell yog tsim los ntawm kev sib xyaw ntawm asbestos thiab polymers. Cov tshuaj nyob rau hauv lub cell tuaj yeem nkag mus los ntawm cov khoom siv no los ntawm cov anode compartment mus rau cathode compartment. Peb tuaj yeem siv lub xovtooj ntawm no kom tau chlorine los ntawm electrolyzing ntawm sodium chloride tov. Lub anode feem ntau yog titanium, thiab cathode yog hlau. Chlorine los ntawm anode, thaum hydrogen los ntawm cathode. Tsis tas li ntawd, cov tshuaj tawm los ntawm cathode yog cov tshuaj sodium hydroxide uas kis tau los ntawm sodium chloride. Txhawm rau kom paub tseeb tias cov kua ntws tsuas yog tshwm sim los ntawm anode mus rau cathode, lub anode compartment ib txwm muaj kua ntau dua.
Qhov txawv ntawm Mercury Cell thiab Diaphragm Cell yog dab tsi?
Mercury cell thiab diaphragm cell yog ob ntawm peb lub hlwb loj uas peb tuaj yeem siv los tsim cov tshuaj chlorine thiab cov dej qab zib caustic. Qhov sib txawv tseem ceeb ntawm mercury cell thiab diaphragm cell yog tias mercury cell feem ntau xav tau qhov hluav taws xob ntau dua thiab muaj zog dua piv rau diaphragm cell. Lub cell mercury feem ntau muaj zinc anode thiab cathode ua los ntawm cov ntshiab mercury (II) oxide los yog sib xyaw ntawm mercury (II) oxide nrog manganese dioxide. Lub diaphragm cell, ntawm qhov tod tes, muaj titanium anode thiab steel cathode.
Cov hauv qab no qhia txog qhov sib txawv ntawm mercury cell thiab diaphragm cell hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Mercury Cell vs Diaphragm Cell
mercury cells thiab diaphragm cells yog ob lub hlwb uas peb tuaj yeem siv los tsim cov tshuaj chlorine thiab caustic soda. Qhov sib txawv tseem ceeb ntawm mercury cell thiab diaphragm cell yog tias mercury cell feem ntau xav tau qhov hluav taws xob ntau dua thiab lub zog ntau dua piv rau diaphragm cell.
