Nyob rau hauv lub ntiaj teb no ntawm kev tsim kho thiab kev lag luam kev siv, galvanized steel yog dav suav hais tias yog ib qho ntawm cov khoom siv ruaj khov tshaj plaws. Nws qhov kev tiv thaiv corrosion yog qhov laj thawj tseem ceeb rau nws qhov chaw, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov hlau raug rau huab cua hnyav. Shandong Sino Steel Co., Ltd., ib tug ua chaw tsim tshuaj paus ntawm galvanized steel coils thiab galvanized steel ntawv , tsim cov khoom zoo uas tsis yog tsuas yog txhim khu kev qha, tab sis kuj pom kev txaus siab. Kab lus no yuav tshawb txog qhov tseeb ntawm galvanized steel qhov xeb tiv thaiv, nws ua haujlwm li cas, thiab vim li cas nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam lag luam, los ntawm kev tsim kho mus rau kev tsim khoom.
Dab tsi yog 'Xeb pov thawj' Tiag tiag rau hlau?
Thaum peb xa mus rau cov hlau tsis xeb, peb feem ntau xav txog cov hlau uas yuav tsis xeb lossis xeb, txawm tias muaj xwm txheej. Txawm li cas los xij, 'rust-proof' yog ib lo lus me ntsis yuam kev. Thaum galvanized steel muaj kev tiv thaiv zoo tiv thaiv xeb, nws tsis yog tiv thaiv corrosion. Nkag siab qhov sib txawv ntawm 'corrosion' thiab 'rust' yog qhov tseem ceeb hauv kev ntsuas qhov ua tau zoo ntawm cov hlau galvanized.
Corrosion vs. Rust - Qhov txawv
Corrosion yog hais txog kev ua kom tsis zoo ntawm cov hlau vim muaj tshuaj lom neeg nrog nws ib puag ncig. Xwb, ntawm qhov tod tes, tshwj xeeb yog hais txog cov xim liab-xim av flaky uas tsim thaum hlau thiab oxygen hnov mob hauv dej. Tsis yog txhua qhov corrosion ua rau xeb, tab sis tag nrho cov xeb yog ib daim ntawv ntawm corrosion.
Galvanized steel, uas yog coated nrog ib txheej ntawm zinc, yog heev resistant rau cov txheej txheem no. Cov txheej zinc tiv thaiv kev sib cuag ncaj qha ntawm cov hlau thiab ib puag ncig cov ntsiab lus xws li ya raws thiab huab cua, uas yog thawj qhov ua rau xeb. Thaum corrosion tshwm sim, zinc corrodes ua ntej, tawm hauv cov hlau tiv thaiv.
Vim li cas Zinc Matters hauv Kev Tiv Thaiv Corrosion
Zinc plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm galvanized steel hauv kev tiv thaiv xeb. Thaum lub sij hawm galvanizing txheej txheem, zinc yog bonded rau steel nto, tsim ib tug tiv thaiv txheej. Cov txheej no ua ib qho thaiv, ua kom cov dej noo thiab huab cua kom deb ntawm cov hlau hauv qab. Tsis tas li ntawd, zinc yog kev txi - txhais tau hais tias nws corrodes ua ntej cov hlau ua, tiv thaiv lub hauv paus hlau los ntawm oxidation. Qhov kev txi no yog qhov tseem ceeb rau lub neej ntev ntawm cov hlau galvanized, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nyuaj.
Galvanizing txheej txheem thiab xeb kuj
Cov txheej txheem los ntawm kev tsim cov hlau galvanized yog qhov tseem ceeb rau nws cov khoom xeb-resistant. Ob txheej txheem tseem ceeb yog siv los tsim cov hlau galvanized: kub-dip galvanizing thiab electrogalvanizing. Txhua txoj kev muaj nws tus kheej zoo thiab yog siv rau cov ntawv thov sib txawv nyob ntawm seb qhov yuav tsum tau muaj kev tiv thaiv thiab kev npaj siv.
Kub-Dip Galvanizing vs. Electrogalvanizing
Kub-dip galvanizing yog txoj kev siv ntau tshaj plaws thiab ua tau zoo rau kev tsim cov hlau galvanized. Nyob rau hauv cov txheej txheem no, cov hlau yog dipped rau hauv molten zinc, tsim ib tug tuab, check txheej uas adheres rau saum npoo. Lub thickness ntawm zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv xeb thiab xeb, ua rau nws tsim nyog rau kev siv sab nraum zoov thiab kev lag luam uas cov hlau raug cov dej noo, cov pa phem, thiab lwm yam khoom ib puag ncig.
Electrogalvanizing, ntawm qhov tod tes, siv cov txheej txheem electrolytic los thov txheej txheej ntawm zinc rau cov hlau. Thaum txoj kev no muab kev tiv thaiv zoo, nws tsis muaj zog li kub-dip galvanizing. Electrogalvanized steel feem ntau yog siv rau hauv cov ntawv thov uas cov hlau yuav raug mob me me thiab qhov twg cov txheej txheej nyias tuaj yeem siv tau.
Zinc Barrier & Sacrificial Protection Mechanism
Cov khoom tiv thaiv ntawm galvanized steel los ntawm nws qhov tshwj xeeb zinc barrier. Cov txheej zinc ua raws li lub cev tiv thaiv kev tiv thaiv kom tsis txhob ya raws thiab oxygen kom ncav cuag cov hlau. Tsis tas li ntawd, yog tias cov zinc txheej yog khawb lossis puas, nws tseem tiv thaiv cov hlau hauv qab los ntawm kev tiv thaiv kev txi. Zinc corrodes ua ntej, tiv thaiv cov hlau los ntawm xeb thiab ncua nws txoj sia.
Ntev npaum li cas Galvanized hlau tiv thaiv xeb
Ib qho ntawm cov lus nug feem ntau txog galvanized steel yog ntev npaum li cas ua ntej nws pib xeb. Cov lus teb yog nyob ntawm ntau yam, nrog rau ib puag ncig uas nws siv, lub thickness ntawm zinc txheej, thiab theem ntawm kev raug ya raws thiab lwm yam corrosive agents.
Environmental Factors cuam tshuam rau lub neej ntev
Lub neej ntev ntawm galvanized steel yog heev cuam tshuam los ntawm ib puag ncig yam. Hauv qhov chaw qhuav, sab hauv tsev, galvanized steel tuaj yeem nyob rau ntau xyoo lawm yam tsis muaj kev cuam tshuam loj. Hauv qhov sib piv, qhov chaw sab nraum zoov uas muaj cov av noo siab, cua ntsev (xws li cov chaw ntug dej hiav txwv), los yog muaj kuab paug tuaj yeem ua kom lub zog ntawm zinc txheej.
Piv txwv li, galvanized steel siv nyob rau hauv ib lub tsev lag luam uas muaj me me rau ya raws yuav kav ntev li 20 mus rau 30 xyoo, thaum galvanized steel siv nyob rau hauv cov ntug dej hiav txwv cheeb tsam yuav tsuas kav 5 mus rau 10 xyoo vim corrosive xwm ntawm ntsev thiab high humidity.
Kev Tiv Thaiv Patina thiab Yuav Ua Li Cas Nws Txhim Kho
Thaum lub sij hawm, galvanized steel tsim ib txheej tiv thaiv hu ua patina. Cov txheej no txhim kho thaum zinc reacts nrog huab cua thiab noo noo. Lub patina ua raws li qhov cuam tshuam thib ob, muab kev tiv thaiv ntxiv tiv thaiv corrosion. Hauv cov ntsiab lus, patina no pab ua kom qeeb ntawm cov txheej txheem corrosion, kom ntseeg tau tias cov hlau galvanized tseem ua tau zoo txawm tias tom qab xyoo dhau los ntawm cov khoom.
Thaum Galvanized Steel tuaj yeem xeb
Txawm hais tias galvanized steel yog heev tiv taus xeb, muaj qee yam kev mob nyob rau hauv uas xeb tseem tuaj yeem tsim. Nws yog ib qho tseem ceeb kom nkag siab txog cov xwm txheej no txhawm rau tswj kom muaj kev ncaj ncees ntawm galvanized steel lub sijhawm.
Kos thiab Mechanical Damage
Lub hauv paus ua rau xeb ntawm galvanized steel yog txhua yam kev puas tsuaj. Yog tias cov zinc txheej tiv thaiv raug khawb los yog cuam tshuam, cov hlau raug puas tsuaj rau corrosion. Qhov no yog qhov tseeb tshwj xeeb yog tias khawb lossis puas tsuaj tshwm sim hauv thaj chaw uas cov dej noo lossis cov pa phem tuaj yeem sau tau.
Ib puag ncig hnyav
Nyob rau hauv ib puag ncig hnyav heev, xws li marine los yog chaw lag luam, galvanized steel tej zaum yuav muaj kev ua kom corrosion. Cov ntsev ntau hauv huab cua, tshuaj lom neeg, thiab lwm yam corrosive tuaj yeem hnav cov zinc txheej sai dua, tso cai rau xeb rau ntawm cov hlau raug. Thaum galvanized steel muab kev tiv thaiv zoo heev, cov cheeb tsam no tseem yuav xav tau kev saib xyuas ntau zaus lossis cov txheej txheem tiv thaiv ntxiv.
Muab piv Galvanized Steel Coil & Sheet Durability hauv kev siv tiag
Ob qho tib si galvanized steel coils thiab galvanized steel los xij yog ruaj khov, tab sis lawv cov kev ua tau zoo tuaj yeem sib txawv nyob ntawm daim ntawv thov tshwj xeeb. Shandong Sino Steel Co., Ltd. muaj ob qho kev xaiv, txhua tus muaj qhov tshwj xeeb zoo hauv kev lag luam sib txawv.
Kev lag luam vs. Kev Siv Khoom Siv
Hauv cov ntawv thov kev lag luam, galvanized steel coils thiab nplooj ntawv yog siv rau ntau lub hom phiaj, nrog rau cov vov tsev, cladding, fencing, thiab cov khoom siv. Lub durability ntawm galvanized steel nyob rau hauv cov ntaub ntawv no yog ib qho tseem ceeb, vim hais tias nws yuav tsum tau tiv taus ya raws, tshuaj, thiab huab cua kub.
Hauv kev tsim kho kev lag luam, galvanized steel feem ntau yog siv hauv thav duab, vov tsev, thiab sab nraum zoov. Lub corrosion kuj ntawm galvanized steel ua rau nws zoo tagnrho rau tej yaam num raug rau lub ntsiab, kom ntseeg tau tias ntev kev ua tau zoo txawm nyob rau hauv hnyav huab cua.
