修(xiu)復汽車鉛酸蓄電池極板(ban)硫化(hua)，要依據硫化(hua)程度選擇(ze)恰當方法(fa)。

對(dui)于輕度(du)(du)和中度(du)(du)硫化(hua)的極板，可先對(dui)電(dian)(dian)(dian)池(chi)完全充電(dian)(dian)(dian)，接(jie)著以(yi)10至20小(xiao)時(shi)率放(fang)電(dian)(dian)(dian)，6V電(dian)(dian)(dian)池(chi)放(fang)到(dao)5.4V，12V電(dian)(dian)(dian)池(chi)放(fang)到(dao)10.8V。隨后打開(kai)電(dian)(dian)(dian)瓶更換電(dian)(dian)(dian)解(jie)液，采用(yong)1.04 - 1.06g/cm3的高純度(du)(du)電(dian)(dian)(dian)解(jie)液，以(yi)低電(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)超20小(xiao)時(shi)，直至電(dian)(dian)(dian)解(jie)液密度(du)(du)不再上(shang)升。若(ruo)測試(shi)容(rong)量達80%以(yi)上(shang)，即為修復。而(er)重度(du)(du)硫化(hua)的極板，處理方式(shi)更專業。先向電(dian)(dian)(dian)池(chi)注入(ru)10%的硫酸鈉水(shui)溶液或0.1% - 0.5%的碳酸鉀水(shui)溶液，以(yi)低電(dian)(dian)(dian)流(liu)連(lian)續充電(dian)(dian)(dian)70 - 80小(xiao)時(shi)。之后徹底沖洗掉(diao)溶液，用(yong)純水(shui)洗凈，加(jia)入(ru)1.40g/cm3的電(dian)(dian)(dian)解(jie)液并調整至標準密度(du)(du)。經(jing)過一(yi)次正常充放(fang)電(dian)(dian)(dian)循環后，若(ruo)容(rong)量恢(hui)復到(dao)90%左(zuo)右(you)，修復便完成(cheng)。

汽車鉛酸蓄電池極板(ban)硫化(hua)的修復，關鍵在于準(zhun)確判(pan)斷硫化(hua)程度，嚴格按照對應方法操作，如此才(cai)能(neng)有(you)效恢復電池性能(neng)，延長其使(shi)用壽命(ming)。
