1.Vim li cas lub thickness ntawm galvanized txheej yog ib qho kev txiav txim siab?
Zinc's corrosion tiv thaiv mechanism cia siab rau kev tiv thaiv electrochemical ntawm "sacrificial anode." Zinc yog ntau reactive tshaj hlau thiab yuav corrode ua ntej hlau. Yog li ntawd, ib txheej zinc thicker txhais tau hais tias ntau "cov khoom siv fij" tuaj yeem noj tau, thiab qhov ntev ntawm cov hlau substrate raug tiv thaiv.
Galvanized tiaj tus hlau: Muaj cov tuab "zinc armor," uas tau noj maj mam thiab muaj lub neej ntev heev.
Galvanized coil: Muaj txheej txheej zinc txheej, zoo li lub tsho nyias nyias. Thaum corrosion pib ntawm khawb los yog cov npoo, nws tau noj sai heev, ua rau cov hlau sab hauv lub substrate xeb.
2.Dab tsi yog "pob nyhuv"?
Cov galvanized coils uas koj tau yuav, tom qab tau zawv zawg - txiav, sheared, thiab stamped, tsis muaj zinc txheej tiv thaiv ib qho ntawm lawv qhov chaw ua tiav. Corrosion yuav pib ntawm no thiab kis mus rau sab hauv.
Kub-dip galvanized ca steel, ntawm qhov tod tes, yog galvanized tsuas yog tom qab nws tau tsim, yog li tag nrho cov npoo thiab cov ces kaum yog tag nrho nrog ib tug tuab zinc txheej, tshem tawm qhov tsis muaj zog.
3.Dab tsi yog cov ntsiab lus thiab xaiv cov lus pom zoo?
Rau qhov kawg corrosion kuj thiab lub neej ntev kev pab cuam nyob rau hauv cov qauv tseem ceeb, sab nraum zoov raug ib puag ncig, los yog raws li ncaj kawg - siv cov Cheebtsam: Xaiv kub-dip galvanized ca steel (los yog kub-dip galvanized profiles xws li lub kaum sab xis steel thiab channel steel) yam tsis muaj hesitation. Nws muab cov nyiaj rov qab ntau dua ntawm kev nqis peev; Txawm hais tias chav tsev tus nqi siab dua, nws lub neej ntev thiab cov nqi kho mob tsawg yog qhov tseem ceeb.
Rau qhov tsis yog -load- cov qauv kabmob, ib puag ncig sab hauv tsev, cov ntawv thov uas yuav tsum tau ua haujlwm thib ob (xws li khoov thiab vuam), lossis tus nqi siab heev- cov xwm txheej rhiab heev: Cov khoom lag luam ua los ntawm galvanized coils tuaj yeem siv tau. Txawm li cas los xij, lawv cov kev txwv kev tiv thaiv corrosion yuav tsum raug lees paub, thiab kev kho yuav tsum tau ua.
4.Yog galvanized coil qhov chaw siv los ua ib qho kev tiv thaiv tsis tau, lawv yuav ua li cas thiaj li txhim kho corrosion?
Ntug Kev Kho Mob: Tom qab tshem tawm tag nrho cov txiav thiab drilled npoo, siv zinc- nplua nuj xim los yog tshuaj tiv thaiv - xeb xim. Qhov no yog kauj ruam tseem ceeb tshaj plaws.
Zuag qhia tag nrho Txheej: Nyob rau hauv ib puag ncig hnyav, ib txheej ntxiv ntawm sab nraum zoov- qib tiv thaiv xim tuaj yeem siv rau tag nrho saum npoo ntawm galvanized coil, tsim "ob chav tiv thaiv."
Xaiv Thick- Txheej Galvanized Coils: Thaum yuav khoom, qhia meej meej thov galvanized coils nrog zinc txheej hnyav (piv txwv li, 275g / m², txhais tau tias ob npaug -sided zinc txheej tuab ntawm kwv yees li 55μm lossis ntau dua). Txawm hais tias qhov no nce tus nqi, nws tseem txhim kho corrosion kuj.
5.Dab tsi ua rau qhov sib txawv ntawm corrosion kuj?
Qhov sib txawv ntawm kev tiv thaiv corrosion feem ntau yog los ntawm cov tuab ntawm txheej galvanized thiab kev tiv thaiv ntawm cov npoo thiab cov fab. Ua ib qho kev xaiv paub raws li koj daim ntawv thov thiab kev ua neej nyob.
