Cov yam ntxwv muaj feem xyuam rau kev khaws cia thiab ntim cov khoom siv hluav taws xob cua sov

Nyob rau hauv atmospheric tej yam kev mob, ferrous hlau yog coated nrog zinc los tiv thaiv corrosion. Tab sis thaum cov zinc txheej los rau hauv kev sib cuag nrog phenolic xim, alkyd xim, phenolic yas, ntub ntoo, plywood, thiab lwm yam., corrosion ntawm zinc txheej yog heev hnyav. Lub sij hawm ntev, qhov thicker cov khoom corrosion. Qhov no yog qhov ua kom nrawm ntawm qhov me me ntawm cov organic tsis hloov pauv huab cua ntawm atmospheric corrosion, hu ua atmospheric corrosion. Cov khoom uas muaj peev xwm tsim tau xws li cov organic volatile cua muaj xws li xim, yas, resin, ntoo, thiab lwm yam. Qhov corrosion ntawm huab cua corrosion yog ze ze rau cov concentration ntawm cov organic volatile cua, thiab qhov siab dua qhov concentration, qhov corrosion hnyav dua. Txawm li cas los xij, cov organic volatile atmospheres tsuas tuaj yeem corrode zinc txheej hauv cov huab cua ntub. Yog hais tias tsuas muaj corrosive cua thiab cov huab cua ib puag ncig yog qhuav, corrosion yog yeej tsis tuaj. Yog li ntawd, nyob rau hauv cov huab cua, zinc txheej yog txhim khu kev qha tiv thaiv txheej tsuas yog nyob rau hauv tej yam kev mob uas tsis muaj organic volatile atmospheres los yog tag nrho cov huab cua qhuav. Thaum lub sij hawm cia cov txheej txheem ntawm electroplated tsim nyog qhov chaw, nws yog tsim nyog los xyuas kom meej lub warehouse ib puag ncig thiab tsis txhob atmospheric corrosion ntawm qhov chaw. Tsis tas li ntawd, thaum lub sij hawm thauj mus los, cov khoom ntim ncaj qha cuam tshuam rau corrosion kuj ntawm cov khoom. Yog li ntawd, nws yog ib qho tsim nyog kom txo qis qhov chaw ntawm cov organic volatilization cua. Galvanized qhov chaw yuav tsum tau ntim thiab khaws cia rau hauv cov thawv ntoo, nrog kev txhim khu kev lag luam sab hauv thiab cov khoom desiccant ntxiv kom ntseeg tau tias muaj kev sib cais ua tiav los ntawm cov cua corrosive sab nraud. Txwv tsis pub, cov khoom tau yooj yim corroded, cuam tshuam cov khoom zoo thiab ua rau muaj kev cuam tshuam tsis zoo. Cov yam ntxwv sab nraud no yooj yim saib tsis tau thiab dhau los ua qhov tseem ceeb cuam tshuam rau qhov zoo ntawm electroplating.

epilogue

Electroplating, raws li hom kev ua haujlwm tshwj xeeb hauv kev tsim khoom, yog qhov tsis tseem ceeb tab sis feem ntau tsis ua tiag tiag. Thaum muaj teeb meem zoo tshwm sim, tsuas yog nrhiav qhov laj thawj los ntawm cov txheej txheem electroplating thiab tsis quav ntsej lwm yam sab nraud. Yog li ntawd, txhawm rau kom ntseeg tau tias cov khoom lag luam electroplating zoo, tsis yog tsuas yog lub rhiav electroplating xwb, tab sis kuj tseem muaj tag nrho cov kev tswj xyuas zoo yuav tsum muaj lub luag haujlwm meej thiab kev tso cai, sim xav txog cov txheej txheem electroplating kom ntau li ntau tau, thiab muab cov txheej txheem zoo rau electroplating. ua. Los ntawm kev kos duab tsim los ua cov txheej txheem thiab kev npaj kho, los ntawm cov khoom ua, sib dhos, tshuaj xyuas, kev thauj mus los, kev cia, thiab thaum kawg ntim thiab thauj, txhua kauj ruam yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias qhov zoo ntawm electroplating, uas yog qhov tseem ceeb tshaj plaws rau kev txhim kho cov khoom zoo. .
