Kev txheeb xyuas ntawm electrogalvanized steel grating thiab kub-dip galvanized steel grating

Yav dhau los, qhov sib txawv ntawm electrogalvanized steel grating thiab kub-dip galvanized steel grating tsuas yog tso siab rau kev soj ntsuam xyuas ntawm zinc spangles. Zinc spangles hais txog cov tsos ntawm cov nplej tsim tom qab kub-dip galvanized steel grating yog rub tawm ntawm lub lauj kaub tshiab thiab zinc txheej txias thiab solidifies. Yog li ntawd, qhov saum npoo ntawm kub-dip galvanized steel grating feem ntau yog ntxhib, nrog cov zinc spangles, thaum lub ntsej muag ntawm electrogalvanized steel grating yog du. Txawm li cas los xij, nrog kev txhim kho cov thev naus laus zis tshiab, kub-dip galvanized steel grating tsis muaj cov yam ntxwv ntawm cov zinc spangles zoo tib yam. Qee zaum qhov saum npoo ntawm kub-dip galvanized steel grating yog ci dua thiab muaj kev cuam tshuam ntau dua li ntawm electrogalvanized steel grating. Qee zaum, thaum kub-dip galvanized steel grating thiab electrogalvanized steel grating muab tso ua ke, nws yog ib qho nyuaj rau kev paub qhov twg yog qhov kub-dip galvanized steel grating thiab uas yog electrogalvanized steel grating. Yog li ntawd, ob qho tib si tsis tuaj yeem paub qhov txawv ntawm qhov tshwm sim tam sim no.

Tsis muaj txoj hauv kev qhia kom paub qhov txawv ntawm ob txoj hauv kev galvanizing hauv Suav teb los yog thoob ntiaj teb, yog li nws yog ib qho tsim nyog los kawm txog qhov txawv ntawm ob txoj hauv kev los ntawm cov hauv paus ntsiab lus. Nrhiav qhov sib txawv ntawm ob los ntawm lub hauv paus ntsiab lus ntawm galvanizing
, thiab paub qhov txawv ntawm qhov muaj lossis tsis muaj Zn-Fe alloy txheej hauv cov ntsiab lus. Thaum pom tseeb, nws yuav tsum yog qhov tseeb. Lub hauv paus ntsiab lus ntawm kub-dip galvanizing ntawm steel grating cov khoom yog rau immersed cov khoom steel tom qab ntxuav thiab ua kom cov molten zinc kua, thiab los ntawm cov tshuaj tiv thaiv thiab diffusion ntawm hlau thiab zinc, zinc alloy txheej nrog zoo adhesion yog plated rau saum npoo ntawm steel grating khoom. Txoj kev tsim cov txheej txheem kub-dip galvanizing txheej txheem yog qhov tseem ceeb ntawm kev tsim cov hlau-zinc alloy ntawm cov hlau matrix thiab txheej txheej zinc txheej sab nraud. Nws muaj zog adhesion kuj txiav txim siab nws zoo heev corrosion kuj. Los ntawm cov qauv microscopic, nws tau pom zoo li ob txheej txheej.
Lub hauv paus ntsiab lus ntawm electrogalvanizing ntawm steel grating cov khoom yog siv electrolysis los tsim ib tug uniform, ntom, thiab zoo-bonded hlau los yog alloy deposition txheej nyob rau saum npoo ntawm cov hlau grating qhov chaw, thiab tsim ib txheej ntawm cov hlau grating, thiaj li ua tiav cov txheej txheem ntawm kev tiv thaiv cov hlau grating los ntawm corrosion. Yog li ntawd, electro-galvanized txheej yog ib hom txheej uas siv cov kev taw qhia ntawm cov hluav taws xob tam sim no los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode. Zn2+ nyob rau hauv cov electrolyte nucleates, loj hlob thiab tso rau ntawm steel grating substrate nyob rau hauv qhov kev txiav txim ntawm lub peev xwm los tsim ib tug galvanized txheej. Hauv cov txheej txheem no, tsis muaj txheej txheem diffusion ntawm zinc thiab hlau. Los ntawm kev soj ntsuam microscopic, nws yog qhov tseeb zinc txheej.
Hauv cov ntsiab lus, kub-dip galvanizing muaj txheej hlau-zinc alloy thiab txheej zinc ntshiab, thaum electro-galvanizing tsuas muaj cov zinc txheej ntshiab. Lub xub ntiag los yog tsis muaj hlau-zinc alloy txheej hauv txheej yog lub hauv paus tseem ceeb rau kev txheeb xyuas cov txheej txheem txheej. Metallographic method thiab XRD txoj kev yog siv los xyuas cov txheej txheem kom paub qhov txawv ntawm electro-galvanizing los ntawm kub-dip galvanizing.
