Electrolysis tshwm sim thaum muaj hluav taws xob tam sim no tawm ntawm nws txoj hauv kev vim kev xaim tsis raug lossis qhov tsis xws luag tuaj ntawm ob lub hlau nyob rau hauv lub xub ntiag ntawm electrolyte, feem ntau yog dej hiav txwv hauv qhov no. Galvanic corrosion kuj yog thaum ob qho tib si hlau nyob rau hauv kev sib cuag nyob rau hauv lub xub ntiag ntawm anelectrolyte.
Ib yam li ntawd, nws raug nug, ua li cas corrosion tshwm sim hauv electrolysis?
Electrolytic corrosion kuj yog ib tug txheej txheem ntawm accelerated corrosion . Hauv txheej txheem no, ib tug metallicsurface yog tsis tu ncua corroded los ntawm lwm yam hlau nws yog hauv tiv tauj nrog, vim ib electrolyte thiab qhov ntws ntawm cov hluav taws xob tam sim no ntawm ob lub hlau, tshwm sim los ntawm lwm qhov chaw ntawm electromotive force (EMF).
Qhov thib ob, cov hlau twg tuaj yeem siv rau electrolysis? Kev lag luam siv Electrometallurgy yog cov txheej txheem ntawm kev txo qis hlau los ntawm metallic compounds kom tau cov ntshiab daim ntawv ntawm hlau siv electrolysis . Aluminium, lithium, sodium, potassium, magnesium, calcium, thiab qee zaum tooj liab, yog ua nyob rau hauv no txoj kev.
Ib yam li ntawd, tib neeg nug, dab tsi yog txhais los ntawm galvanic corrosion?
Galvanic corrosion kuj (tseem hu ua bimetallic corrosion ) yog txheej txheem electrochemical nyob rau hauv uas ib tug metalcorrodes nyiam thaum nws nyob rau hauv hluav taws xob sib cuag nrog lwm tus, nyob rau hauv lub xub ntiag ntawm ib tug electrolyte.
Yuav ua li cas galvanic corrosion yuav txo tau?
Galvanic corrosion tuaj yeem tiv thaiv los ntawm ntau txoj hauv kev:
- Xaiv cov hlau / alloys kom ze li sai tau hauv cov galvanic series.
- Tsis txhob cuam tshuam thaj tsam ntawm qhov me me anode thiab bigcathode.
- Insulate cov hlau tsis sib xws nyob qhov twg los tau.
- Siv cov coatings nrog ceev faj.

Dab tsi ua rau txoj kev xav zoo ib qho kev xav zoo txog kev puas siab puas ntsws?
Ib txoj kev xav zoo yog kev sib koom ua ke - nws piav qhia ntau qhov tseeb thiab kev soj ntsuam hauv ib qho qauv lossis lub hauv paus. Txoj kev xav yuav tsum yog nyob rau hauv ib yam. Ib txoj kev xav zoo yuav tsum ua qhov kev kwv yees uas tuaj yeem kuaj tau. Qhov ntau meej thiab "tseem ceeb" qhov kev xav ntawm kev kwv yees yog - qhov ntau nws nthuav tawm nws tus kheej mus rau kev dag
Puas yog rods Gram tsis zoo los yog zoo?
Gram positive rods tsawg dua li Gram negative rods. Tag nrho cov seem yog Gram negative rods. Gram zoo rods; Actinomyces, Atopobium, Bacillus, Bifidobacterium, Clostridium, Corynebacterium, Erysipelothrix, Gardnerella, Listeria, Lactobacillus, Mycobacterium sp
Puas yog molar kub ntawm combustion zoo los yog tsis zoo?
Thaum tshav kub kub ntawm combustion yog hais raws li tus xov tooj zoo thaum lub enthalpy hloov ntawm combustion tshua (Δ H) yog hais raws li tsis zoo cov zauv, raws li combustion tshwm sim yeej ib txwm exothermic
Puas yog cov txheej txheem ntawm electrolysis ua tau nrog vinegar?
Txawm hais tias electrolysis tuaj yeem ua tiav nrog cov khoom siv hauv tsev, acetic acid (kua txiv kab ntxwv) tsis txhawb electrolysis txaus los tsim kom muaj cov pa roj ntau txaus
Dab tsi yog ntau yam xwm txheej uas tau khaws cia zoo ib yam hauv kev sim?
Ib qho kev sib txawv yog txhua yam, qhov zoo, lossis qhov xwm txheej uas tuaj yeem muaj nyob hauv ntau qhov sib txawv lossis hom. Ib qho kev sim feem ntau muaj peb hom kev hloov pauv: ywj siab, nyob ruaj khov, thiab tswj tau. Qhov kev hloov pauv ywj pheej yog qhov hloov pauv los ntawm tus kws tshawb fawb
