Hluav taws xob galvanizing
Lus piav qhia luv luv:
Electro galvanizing: tseem hu ua txias galvanizing nyob rau hauv kev lag luam, nws yog cov txheej txheem ntawm kev tsim ib tug uniform, ntom thiab zoo bonded hlau los yog alloy deposition txheej nyob rau saum npoo ntawm lub workpiece los ntawm electrolysis.
Piv nrog rau lwm cov hlau, zinc yog pheej yig thiab yooj yim rau plated.Nws yog tus nqi qis los tiv thaiv corrosion electroplated txheej.Nws yog dav siv los tiv thaiv hlau thiab hlau qhov chaw, tshwj xeeb tshaj yog tiv thaiv atmospheric corrosion, thiab kho kom zoo nkauj.Plating tshuab muaj xws li da dej plating (los yog dai plating), chim plating (tsim rau me me), plating xiav, tsis siv neeg plating thiab nruam plating (tsim rau hlau thiab sawb).
yam ntxwv
Lub hom phiaj ntawm electro galvanizing yog los tiv thaiv cov khoom steel los ntawm corroded, txhim kho corrosion kuj thiab kev pab cuam lub neej ntawm steel, thiab ua kom cov hniav zoo nkauj ntawm cov khoom.Hlau yuav corroded los ntawm huab cua, dej los yog av nrog rau lub sij hawm nce.Hauv Suav teb, cov hlau corroded yuav luag ib feem kaum ntawm tag nrho cov hlau ntim txhua xyoo.Yog li ntawd, txhawm rau tiv thaiv lub neej kev pabcuam ntawm cov hlau lossis nws qhov chaw, electro galvanizing feem ntau yog siv los ua cov hlau.
Vim tias zinc tsis yooj yim rau kev hloov pauv hauv huab cua qhuav thiab tuaj yeem tsim cov zinc carbonate zaj duab xis hauv qhov chaw ntub dej, zaj duab xis no tuaj yeem tiv thaiv sab hauv los ntawm kev puas tsuaj.Txawm hais tias cov zinc txheej raug puas los ntawm qee yam, zinc thiab hlau yuav ua ke los tsim cov roj teeb micro tom qab lub sijhawm, kom cov hlau matrix ua cathode thiab tiv thaiv.Nws tau xaus lus tias electro galvanizing muaj cov yam ntxwv hauv qab no:
Nws muaj kev tiv thaiv corrosion zoo, zoo thiab sib xyaw ua ke, thiab tsis yooj yim rau nkag los ntawm corrosive gas lossis kua.
Vim tias zinc txheej yog cov ntshiab, nws tsis yooj yim rau corroded hauv acid lossis alkali ib puag ncig.Zoo tiv thaiv lub cev steel rau lub sijhawm ntev.
Nws tuaj yeem siv ntau yam xim tom qab chromate passivation.Nws tuaj yeem raug xaiv raws li cov neeg siv khoom nyiam.Galvanizing yog zoo nkauj thiab zoo nkauj.
Lub zinc txheej muaj qhov zoo ductility thiab yuav tsis poob yooj yim thaum muaj ntau yam dabtsi yog khoov, tuav thiab cuam tshuam.
