2. Cov txheej txheem electrolysis ntawm tooj liab cathodes

2.1. electrolysis yog dab tsi?

Electrolysis yog cov txheej txheem tshuaj uas siv hluav taws xob tam sim no los tsav cov tshuaj tiv thaiv uas tsis yog tshwm sim. Nyob rau hauv cov ntsiab lus ntawm tooj liab ntau lawm, electrolysis yog siv los ua kom zoo tooj liab los ntawm nws cov ore thiab tsim high-purity tooj liab cathodes. Cov txheej txheem cuam tshuam nrog cov tooj liab ions los ntawm ib qho anode thiab tso rau hauv cathode los ntawm kev siv hluav taws xob tam sim no.

2.2. Cov kauj ruam koom nrog hauv tooj liab electrolysis

Cov txheej txheem electrolysis ntawm tooj liab ntau lawm muaj ob peb kauj ruam:

2.3. Lub luag haujlwm ntawm electrolytes thiab anodes

Cov electrolyte siv hauv tooj liab electrolysis yog ib qho kev daws ntawm tooj liab sulfate thiab sulfuric acid. Cov tshuaj no muaj tooj liab ions uas tso rau hauv cathode thaum electrolysis. Lub anode yog ua los ntawm cov tooj liab tsis huv, uas yaj thiab tso cov tooj liab ions rau hauv electrolyte. Raws li cov txheej txheem electrolysis txuas ntxiv, cov anode maj mam ploj zuj zus, thaum lub cathode ua dawb huv.

3. Daim ntawv thov ntawm high-purity tooj liab cathodes

3.1. Hluav taws xob thiab hluav taws xob kev lag luam

High-purity tooj liab yog dav siv nyob rau hauv hluav taws xob thiab hluav taws xob industries vim nws zoo heev conductivity thiab tsis kam mus corrosion. Copper cathodes yog siv los tsim cov xov hlau, cables, thiab cov khoom sib txuas, uas yog qhov tseem ceeb rau kev xa hluav taws xob thiab cov teeb liab hauv ntau daim ntawv thov. Kev lag luam hluav taws xob kuj tso siab rau cov tooj liab siab ntshiab rau kev tsim cov khoom siv hluav taws xob, cov khoom sib txuas, thiab lwm yam khoom siv.

3.2. Kev tsim kho thiab kav dej

Hauv kev tsim kho kev lag luam, tooj liab-purity siab yog siv rau cov kav dej, vov tsev, thiab cladding daim ntaub ntawv. Cov kav dej tooj liab thiab fittings yog nyiam rau lawv cov kav ntev, tsis kam tiv thaiv corrosion, thiab muaj peev xwm tiv taus qhov kub thiab txias. Tooj liab kuj tseem siv rau hauv kev siv vaj tse, xws li vov tsev thiab cladding, vim nws txoj kev zoo nkauj thiab kev ua neej ntev.
