DKGB-12250-12V250AH SEALED MAINTANANCE DAWB GEL roj teeb hnub ci roj teeb

Qhov txawv ntawm lead-acid roj teeb thiab gel roj teeb
Puas yog nws zoo dua los xaiv cov roj ntsha lead-acid lossis gel roj teeb rau hnub ci cell?Qhov txawv li cas?
Ua ntej ntawm tag nrho cov, ob hom roj teeb no yog lub zog cia roj teeb, uas yog tsim rau cov khoom siv hluav taws xob hnub ci.Qhov kev xaiv tshwj xeeb nyob ntawm koj ib puag ncig thiab kev xav tau.

Lead acid roj teeb thiab gel roj teeb ob leeg siv lub ntsiab cai ntawm cathode absorption los kaw lub roj teeb.Thaum Xili roj teeb raug them, tus ncej zoo yuav tso pa tawm thiab cov ncej tsis zoo yuav tso cov hydrogen.Oxygen evolution los ntawm qhov zoo electrode pib thaum qhov zoo electrode nqi nce mus txog 70%.Cov pa oxygen precipitated ncav cuag lub cathode thiab reacts nrog cathode raws li hauv qab no kom ua tiav lub hom phiaj ntawm cathode absorption.Lub hydrogen evolution ntawm qhov tsis zoo electrode pib thaum tus nqi nce mus txog 90%.Tsis tas li ntawd, qhov txo qis ntawm cov pa oxygen ntawm qhov tsis zoo electrode thiab kev txhim kho hydrogen overpotential ntawm qhov tsis zoo electrode nws tus kheej tiv thaiv ib qho loj ntawm hydrogen evolution cov tshuaj tiv thaiv.

Qhov sib txawv loj ntawm ob yog electrolyte curing.

Rau cov roj teeb txhuas-acid, txawm hais tias feem ntau ntawm cov electrolyte ntawm lub roj teeb khaws cia hauv AGM membrane, 10% ntawm cov membrane pores yuav tsum tsis txhob nkag mus rau hauv electrolyte.Cov pa oxygen tsim los ntawm qhov zoo electrode mus txog qhov tsis zoo electrode los ntawm cov pores thiab yog absorbed los ntawm qhov tsis zoo electrode.

Rau gel roj teeb, silicon gel nyob rau hauv lub roj teeb yog ib tug peb-dimensional ntxeem tau network qauv tsim ntawm SiO hais raws li lub cev pob txha, uas encapsulates cov electrolyte nyob rau hauv.Tom qab lub silica sol puv los ntawm lub roj teeb hloov mus rau hauv gel, lub moj khaum yuav ntxiv zuj zus, yog li ntawd cov kab nrib pleb nyob rau hauv lub gel yuav tshwm sim nyob rau hauv lub zoo thiab tsis zoo daim hlau, muab ib tug channel rau cov pa oxygen tso tawm los ntawm lub zoo electrode mus txog qhov zoo electrode.

Nws tuaj yeem pom tias lub hauv paus ntsiab lus ntawm kev sib khi ntawm ob lub roj teeb yog tib yam, thiab qhov sib txawv yog nyob rau hauv txoj kev "kho" electrolyte thiab txoj kev muab cov pa oxygen mus txog qhov tsis zoo electrode channel.

Ntxiv mus, kuj tseem muaj qhov sib txawv ntawm ob hom roj teeb hauv cov qauv thiab thev naus laus zis.Lead acid roj teeb siv cov ntshiab sulfuric acid daws raws li electrolyte.Cov electrolyte ntawm colloidal kaw cov kua qaub roj teeb yog tsim los ntawm silica sol thiab sulfuric acid.Qhov concentration ntawm sulfuric acid daws yog qis dua li cov roj ntsha lead acid.

Tom qab ntawd, lub peev xwm tawm ntawm Xili roj teeb kuj txawv.Colloid electrolyte formula, tswj qhov loj ntawm colloidal hais, ntxiv hydrophilic polymer additives, txo cov concentration ntawm colloidal tov, txhim kho permeability thiab affinity rau lub electrode phaj, txais yuav lub tshuab nqus tsev filling txheej txheem, hloov cov roj hmab separator nrog composite separator los yog AGM separator, thiab txhim kho cov kua nqus dej ntawm lub roj teeb;Lub peev xwm tso tawm ntawm lub roj teeb gel kaw tuaj yeem ncav cuag lossis mus txog qib ntawm lub roj teeb qhib qhib los ntawm kev tshem tawm cov sedimentation tank ntawm lub roj teeb thiab ua kom cov ntsiab lus ntawm cov tshuaj nquag hauv thaj chaw phaj.

AGM kaw cov kua qaub roj teeb muaj cov electrolyte tsawg dua, cov phaj tuab, thiab siv cov khoom siv qis dua li cov roj teeb qhib, yog li lub peev xwm tawm ntawm Xili roj teeb yog li 10% qis dua li cov roj teeb qhib.Piv nrog rau hnub no lub roj teeb gel kaw, nws lub peev xwm tso tawm tsawg dua.Uas yog hais, tus nqi ntawm gel roj teeb yuav kuj siab.
