1.IS nws yuav tsum tau rov ua dua yog cov txheej txheej puas yog puas lossis tev tawm ntawm thaj chaw loj?
Cov txheej zinc tau ploj ntau dua 30% ntawm nws thaj chaw thaj chaw vim muaj kev cuam tshuam ntau dua lossis khawb) lossis xeb (xws li lub sijhawm ntev los ua kom muaj zog los yog alkalis). Tus kab mob Substrate (cov hlau me) tau tsim kho cov xeb muaj xeb (hlau oxide), thiab qhov xeb yog nthuav tawm (xws li nthuav tawm, lossis flaking).
Piv txwv li, cov yeeb nkab steel tau kos los ntawm cov khoom ntse thaum lub sijhawm thauj mus los, tawm ntawm cov hlau ntev ntawm cov hlau nthuav tawm. Yog tias tsis tau hais kom sai sai, liab ntau xeb yuav loj hlob ntawm thiab ib puag ncig ntawm thaj chaw muaj ob lub hlis tom qab.
2.Yow yog conrosion tob cuam tshuam cov qauv teeb tsa?
Rust tuaj yeem txo cov phab ntsa tuab ntawm cov kav hlau (xws li lossis cov kabmob hauv zos (xws li cov kav dej hauv zos (xws li cov kav dej hauv zos (xws li kev txhawb nqa lub zog thiab kev txhawb nqa), kev nyab xeeb thoob plaws), kev nyab xeeb tshaj plaws), kev nyab xeeb.
NCO TSEG: Pitting me (ib-taw tes xeb tsawg dua 0.5 hli) Tsis muaj xim sib kis tau nrog kov cov xim, tsis tas yuav rov qab ua dua.
3.Yog li cas yog qhov cuam tshuam ntawm ib puag ncig kev siv?
Yog tias cov yeeb nkab steel siv rau hauv ib puag ncig corrosive (xws li cov txheej txheem tiv thaiv kab mob / cov khoom noj kom zoo nkauj (xws li cov khoom lag luam ntawm cov khoom lag luam kev tiv thaiv.
4.Qhov dab tsi yog qhov xwm txheej uas rov ua dua tshiab tuaj yeem suav tau?
Yog tias cov txheej sib txawv tab sis cov nqi kho kom zoo dua qub), xws li cov roj ntsha uas tau ua haujlwm lossis cov khoom siv tsis muaj zog (xws li cov roj ntsha tsis zoo Hauv qhov no, rov ua dua yog kev lag luam ntau dua (piv txwv li yog qhov ua kom zoo dua qub lossis cov kav dej hauv cov phiaj xwm kho dua tshiab), rov ua dua tshiab yog pom zoo kom rov ua kom muaj kev tiv thaiv corrosion los xyuas kom muaj lub neej pabcuam ntau tshaj 5 xyoos.
5.Qhov dab tsi yog cov xwm txheej uas rov ua dua galvanizing tsis tsim nyog?
Yog tias tsuas yog ib qho me me ntawm cov xim dawb (cov khoom siv corrosion (muaj cov hmoov txhuam hniav dawb lossis tom qab ntawd nws tuaj yeem hloov kho cov kab mob khaub thuas.
Yog tias muaj thaj chaw me me ntawm cov hlau nplaum uas nthuav tawm (<5 cm² per spot, <10% of the total area) without red rust, it can be sanded and then coated with an epoxy primer and zinc topcoat without re-galvanizing.
