1.What yog cov tiv thaiv corrosion ntawm galvanized chev nws tus kheej?
Zinc txheej muab kev tiv thaiv rau lub hauv paus ntawv steel los ntawm kev tiv thaiv kab mob anode (zinc corrodes thawj zaug) thiab lub cev muaj zog cuam tshuam (cais dej thiab oxygen).
Txheem galvanized coils feem ntau muaj zinc txheej ntawm ob sab (tshwj tsis yog tias lawv tshwj xeeb cov khoom siv tshwj xeeb ntawm cov khoom lag luam ntawm cov khoom lag luam). Txawm li cas los xij, hauv qee qhov xwm txheej, cov txheej tom qab me ntsis yuav raug puas me ntsis (xws li khawb thiab hauv qab) vim kev txiav thiab tuav).
Yog li ntawd, nyob rau hauv cov xwm txheej zoo tshaj plaws (ua kom tiav txheej thiab tsis muaj kev puas tsuaj), lub nraub qaum zinc txheej nws tus kheej muaj ib qho kev tiv thaiv kev tiv thaiv corrosion thiab tsis muaj kev kho mob ntxiv.
2.Yog nws yuav tsum tau ua kom rov qab tiv thaiv corrosion yog tias cov khaub ncaws rov qab puas lossis tsis tiav?
Cov txheej txheem ua (xws li shearing, stamping, vuam) tej zaum yuav ua rau lub nraub qaum kom raug khawb los yog tev tawm, ua rau lub hauv paus hauv paus steel phaj. Yog tias nws tsis raug kho, nws yuav dhau los ua qhov pib ntawm corrosion (tshwj xeeb yog nyob hauv ib puag ncig noo).
Tshwj xeeb customized ib-sided galvanized coils (tsuas yog sab pem hauv ntej muaj ib sab steel phaj) tsis muaj kev tiv thaiv nrog kev tiv thaiv corrosion (xws li pleev xim, txau).
3.Qhov yog cov xwm txheej raug nyob qhov twg sab nraum qab yuav tsum muaj kev tiv thaiv los ntawm kev xeb?
Daim ntawv thov nyob rau hauv ib puag ncig corrosive heev
Yog tias Galvanized coils tau siv rau hauv cov chaw dej noo (xws li chav dej thiab cov ntug dej hiav txwv ib leeg yuav tsis txaus siab rau cov neeg muaj kuab
Lub zinc txheej noj sai dua hauv cov chaw muaj hluav taws xob ntau huv (xws li cov dej ntws tawm hauv cov av sab nraub qaum thiab ntsev rau hauv av), nws yuav ua tsis tiav.
Nyob rau lub sijhawm no, kev tiv thaiv ntau ntxiv yuav tsum muaj nyob tom qab (xws li Txheej Txheem Epoxy Primer, lossis cov kab xev sab topro-corrosion) kom ntev dua lub neej pabcuam tag nrho.
Cov xwm txheej uas muaj qhov yuav tsum tau ua rau cov neeg tiv thaiv corrosion
Qee qhov haujlwm yuav tsum muaj lub neej tiv thaiv corrosion ntau dua 15 xyoos. Txheej Galvanized Massized yuav maj mam poob tom qab 10-15 xyoo. Ntxiv los tiv thaiv corrosion nyob sab tom qab tuaj yeem tsim "ob npaug tiv thaiv" thiab tseem ceeb kav lub neej.
Cov xwm txheej nyob qhov twg sab nraum qab tuaj yeem nkag rau hauv kev sib cuag electrolyte
Yog tias sab nraum qab ntawm Galvanized Chev tuaj yeem sib cuag nrog cov roj hluav taws xob xws li dej khib nyiab, txawm tias muaj cov roj ntsha, thiab muaj cov txheej txheem muaj micrro. Kev tiv thaiv corrosion ntxiv tuaj yeem cais cov electrolyte thiab thaiv cov tshuaj tiv thaiv corrosion.
4.Qhov dab tsi yog qhov xwm txheej uas nws tsis tsim nyog los ua kom tiv thaiv corrosion nyob tom qab?
Daim ntawv thov nyob rau hauv ib puag ncig qhuav
Rau ib puag ncig sab hauv tsev (xws li cov rooj tog, sab hauv lub tshuab nqus tsev), cov tshuaj rov qab tsis muaj peev xwm tiv thaiv cov dej thiab cov tshuaj ntsuab tsis txaus, thiab tsis muaj kev kho mob ntxiv.
Sab nraum qab yog tsis raug lossis lub cev cais
Yog tias sab nraum qab ntawm Galvanized coil yog them los ntawm lwm cov ntaub ntawv, muaj kev pheej hmoo ntawm kev nkag siab nruab nrab, tsis muaj kev tiv thaiv kev tiv thaiv kab xeb.
Txaus Zinc Txheej Thickness thiab Zoo Tshaj Plaws
Rau tuab zinc txheej coils (xws li zinc txheej tuab> 200-㎡), hauv qab huab cua sab nraum zoov tuaj yeem tiv thaiv ntau tshaj 10 xyoo yam tsis muaj kev kho mob ntxiv.
5.Qhov cov qauv kev kho mob ib txwm muaj rau rov qab tiv thaiv Corrosion?
Painting: Xaiv kev lag luam, xws li cov xim alkyd (haum rau qhuav ib puag ncig), kob fluorocarbon, huab cua tsis kam).
Galvanized Txheej Kev Kho: Rau cov kev puas tsuaj hauv zos, cov tshuaj tsuag txias zinc xim nrog cov ntawv primer siab lossis zinc zoo siv rau kev kho.
Lamination / laminating: muab tshuaj txhuam tiv thaiv corrosion, txheej txheej roj hmab ntawm sab nraub qaum cais tawm ntawm nruab nrab corrosive cais ib puag ncig corrosive corrosive (haum rau kev ua kom huv si).
