Daim ntawv thov ntawm Calcium Aluminium Alloy nyob rau hauv cia roj teeb

2022-10-26

Kev lag luam roj teeb txhuas-acid hauv kuv lub tebchaws muaj keeb kwm ntau tshaj li ib puas xyoo. Vim yog cov yam ntxwv ntawm cov khoom pheej yig, thev naus laus zis yooj yim, thev naus laus zis paub tab, tsis muaj kev tso tawm tus kheej, thiab kev saib xyuas tsis pub dawb, nws tseem yuav ua tus thawj coj hauv kev lag luam hauv ob peb xyoos tom ntej no. Hauv ntau daim ntawv thov, kev ua haujlwm thev naus laus zis ntawm cov roj ntsha lead-acid tau ua rau muaj txiaj ntsig zoo rau kev txhim kho kev sib tw hauv tebchaws. Calcium alloy muaj peev xwm hydrogen siab thiab muaj zog corrosion kuj. Nws yog siv los ua cov hlau lead-acid roj teeb daim phiaj, uas tuaj yeem txhim kho qhov ua tau zoo ntawm cov hluav taws xob tsis zoo rau cov pa oxygen sab hauv ntawm lub roj teeb thiab ua kom cov txiaj ntsig zoo ntawm cov electrode hauv qhov sib sib zog nqus tawm mus.

Daim ntawv thov ntawm Calcium Aluminium Alloy hauv Cia Roj Teeb

Lead-acid roj teeb muaj keeb kwm ze li ntawm 160 xyoo. Nws lub zog tshwj xeeb thiab ntim tshwj xeeb tsis tuaj yeem muab piv nrog Ni-Cd, Ni-MH, Li ion thiab Li polymer roj teeb. Tab sis vim nws tus nqi qis, qhov ua tau zoo tshaj plaws tam sim no, thiab tsis muaj kev nco, nws tuaj yeem ua rau hauv ib lub roj teeb loj loj (4500Ah) thiab lwm yam kev ua tau zoo. Yog li ntawd, nws tseem siv dav hauv tsheb, kev sib txuas lus, hluav taws xob hluav taws xob, UPS, kev tsheb ciav hlau, tub rog thiab lwm yam kev lag luam, thiab nws cov kev muag khoom tseem nyob rau hauv pem hauv ntej ntawm cov khoom siv hluav taws xob.

Yuav ua li cas txhuas calcium alloy yog dav siv hauv kev lag luam roj teeb

1. Txhawm rau txo cov roj teeb dej decomposition thiab txo cov roj teeb ua haujlwm, Hanring thiab Thomas [50] tau tsim cov hlau lead-calcium alloy hauv xyoo 1935, uas tau siv los tsim cov cam khwb cia rau cov roj teeb uas nyob ruaj ruaj siv hauv cov chaw sib txuas lus.

2. Cov khoom siv hluav taws xob feem ntau siv hauv cov roj teeb uas tsis muaj kev saib xyuas yog Pb-Ca alloy. Raws li cov ntsiab lus, nws tau muab faib ua cov calcium siab, nruab nrab calcium thiab tsawg calcium alloy.

3. Cov hlau lead-calcium alloy yog nag lossis daus hardening, uas yog, Pb3Ca yog tsim nyob rau hauv cov hlau lead matrix, thiab cov intermetallic compound precipitates nyob rau hauv cov hlau matrix los ua ib tug hardened network.

Daim phiaj yog cov khoom siv tseem ceeb tshaj plaws hauv cov roj ntsha lead-acid. Txij li thaum lub invention ntawm lead-acid roj teeb, Pb-Sb alloy yog cov khoom tseem ceeb tshaj plaws rau daim phiaj. Nrog rau qhov tshwm sim ntawm kev saib xyuas-dawb txhuas-acid roj teeb, Pb-Sb alloys tau dhau los ua tsis tau raws li kev saib xyuas-dawb kev ua haujlwm ntawm cov roj teeb, thiab maj mam hloov los ntawm lwm cov alloys.

Cov kev tshawb fawb tau pom tias Pb-Ca alloy muaj kev saib xyuas zoo-dawb kev ua tau zoo, tab sis nws qhov tshwm sim ntawm kev cuam tshuam ntawm intergranular yog qhov hnyav, thiab cov ntsiab lus calcium tsis yooj yim los tswj, tshwj xeeb tshaj yog cov high-impedance passivation zaj duab xis tsim nyob rau saum npoo ntawm lub roj teeb daim phiaj cuam tshuam. lub roj teeb them thiab cov txheej txheem tawm. , Ua kom lub roj teeb lub peev xwm thaum ntxov (PCL) tshwm sim aggravated, yog li shortening lub roj teeb txoj kev pab cuam lub neej, ntawm uas lub hwj chim ntawm lub zoo kab sib chaws yog feem ntau. Ntxiv ib qho me me ntawm txhuas muaj cov nyhuv tiv thaiv calcium. Kev tshawb fawb tau pom tias tin tuaj yeem txhim kho kev ua haujlwm ntawm cov yeeb yaj kiab passivation thiab txhim kho qhov kev ua haujlwm sib sib zog nqus ntawm lub roj teeb.
