Cov cawv ntawm kub ntawm VRLA roj teeb
May 23, 2020
K=0.006 / ℃, K=0.008 / ℃ kev sim ntsuas txog 3 teev, muaj peev xwm K=0.01 / ℃ rau kev sim ua haujlwm ntev txog 1 teev. Nws tuaj yeem pom los ntawm kab zauv (1) tias thaum qhov ntsuas kub ntawm huab cua sov siab tshaj 25 ° C, qhov tseeb tawm qhov peev xwm paug Ct ntawm VRLA roj teeb muaj ntau dua li cov qauv tsim muaj peev xwm Ce; thaum lub sij hawm huab cua qhov kub qhov qis dua qis dua 25 ° C, nws qhov tseeb tso tawm Lub peev xwm Ct qis dua qhov tsim cov peev txheej Ce. Nws kuj tseem tuaj yeem pom los ntawm tus nqi ntawm qhov ntsuas kub ntawm cov hluav taws xob K uas ntau dua qhov tso tawm tawm, qhov cuam tshuam ntau dua ntawm kev ntsuas kub ntawm lub peev xwm.
Lub roj teeb muaj peev xwm txo qis nrog qhov ntsuas kub tsis txaus, uas yog ze rau qhov cuam tshuam loj ntawm qhov kub ntawm electrolyte viscosity thiab sab hauv. Thaum lub ntsuas kub ntawm qhov hluav taws xob zoo, qhov siab tshaj qhov nce ceev, sab hauv lub zog poob qis, thiab lub zog ntawm lub tshuab hluav taws xob kuj nce me ntsis. Yog li ntawd, lub peev xwm thiab cov khoom siv nquag siv tus nqi ntawm VRLA roj teeb nce nrog kub. Thaum lub ntsuas kub ntawm qhov electrolyte poob qis, nws cov viscosity nce, qhov ion txav tau raug ntau dua ua hauj, thiab nws lub peev xwm diffusion txo. Thaum muaj qhov kub qis, qhov tsis kam ntawm qhov electrolyte nce thiab qhov tsis kam ntawm qhov hluav taws xob electrochemical nce, uas ua rau lub roj teeb muaj peev xwm tsawg dua.
Nyob rau hauv kev ua haujlwm tsis tshua muaj kev kub ntxhov siab, cov hmoov txhuas txhuam ntawm lub phaj tsis zoo tuaj yeem yooj yim ua cov pob zeb me me uas muaj qhov me me, uas tuaj yeem ua kom khov thiab thaiv cov qhov me me, yog li txo cov kev siv tus nqi ntawm cov khoom siv nquag. Yog tias qhov hluav taws xob tso tawm tam sim no siv nyob rau hauv qhov kub tsis tshua muaj kev kub ntxhov thiab mob hnyav, qhov pores hauv qhov tsis zoo electrode cov khoom siv yuav ua rau muaj kev cuam tshuam ntau, thiab cov hlau lead txhuam yuav ua ntom ntom PbSO4, uas txo cov hluav taws xob ntau uas lub roj teeb tuaj yeem tso tawm. Cov. Rau cov phaj zoo, nws qhov ntsuas kub tsis sib xws yog qhov tsis zoo, yog li nws muaj hluav taws xob ntau dua thaum muaj qhov kub tsawg. Yog li, thaum muaj qhov kub qis, qhov ntsuas hluav taws xob zoo qhov hluav taws xob muaj ntau dua qhov tsis zoo electrode paug tawm. Ua li no, ua ntej cov tsis zoo electrode tsim cov txheej txheem PbSO4, txheej txheem kev hloov pauv ntawm qhov zoo electrode PbO2 rau PbSO4 tau xaus, yog li cov phaj electrode tsis tsim cov hmoov nplej PbSO4 tsawg ntawm qhov kub tsawg. Yog li no, kub dhau hwv yuav ua rau txo qis ntawm lub peev xwm ntawm VRLA roj teeb.
