Galvanized ntawv yog cov khoom siv hlau nrog cov khoom tiv thaiv corrosion, thiab nws cov khoom siv kho tshuab yog qhov tseem ceeb rau nws daim ntawv thov hauv ntau yam. Kab lus no yuav qhia txog cov khoom siv ntawm cov ntawv galvanized kom ntxaws los ntawm cov yam ntxwv ntawm hardness, lub zog, toughness thiab plasticity ntawm cov khoom.
Ua ntej tshaj plaws, lub hardness ntawm galvanized ntawv yog hais txog nws lub peev xwm los tiv thaiv cov yas deformation los ntawm sab nraud quab yuam. Lub hardness ntawm galvanized ntawv feem ntau cuam tshuam los ntawm substrate thiab txheej. Lub hardness ntawm lub substrate nyob ntawm nws cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov txheej txheem, thaum lub hardness ntawm txheej yog nyob ntawm thickness thiab crystallinity ntawm zinc txheej. Feem ntau, cov ntawv galvanized muaj qhov nyuaj dua thiab tuaj yeem muab kev khawb zoo dua thiab hnav tsis kam, haum rau cov ntawv thov uas xav tau kev sib cuag lossis kev sib txhuam.
Qhov thib ob, lub zog ntawm cov ntawv galvanized hais txog nws lub peev xwm los tiv thaiv kev puas tsuaj los ntawm sab nraud quab yuam. Lub zog ntawm cov ntawv galvanized feem ntau suav nrog lub zog tawm los thiab lub zog tensile. Lub zog tawm los yog hais txog tus nqi kev ntxhov siab ntawm cov ntawv galvanized uas pib ua rau cov yas deformation nyob rau hauv lub zog sab nraud, thaum lub zog tensile hais txog qhov siab tshaj plaws ntawm cov ntawv galvanized uas ua rau tsis ua hauj lwm hauv tensile quab yuam. Feem ntau hais lus, daim ntawv galvanized muaj lub zog ntau dua, tuaj yeem muab kev ua haujlwm zoo dua tensile thiab compressive, thiab tsim nyog rau lub sijhawm uas yuav tsum tau tiv thaiv cov rog sab nraud.
Thib peb, lub toughness ntawm galvanized ntawv hais txog nws lub peev xwm los tiv thaiv kev ua ntawm sab nraud quab yuam thiab tawg. Toughness yog ib qho ntawm cov khoom tseem ceeb ntawm cov ntawv galvanized, uas yog ze rau qhov ductility thiab cuam tshuam ntawm cov ntawv galvanized. Lub toughness ntawm galvanized ntawv yog nyob ntawm seb muaj pes tsawg leeg ntawm substrate thiab cov txheej txheem kev kho cua sov, thiab tseem cuam tshuam los ntawm txheej. Feem ntau hais lus, daim ntawv galvanized muaj zog dua, tuaj yeem muab kev cuam tshuam zoo dua thiab kev tiv thaiv tawg, thiab tsim nyog rau lub sijhawm uas yuav tsum tau tiv thaiv sab nraud los yog sib tw.

Thaum kawg, cov ntawv yas ntawm galvanized yog hais txog nws lub peev xwm los ua cov yas deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Plasticity yog ib qho ntawm cov khoom tseem ceeb ntawm cov ntawv galvanized, uas yog ze ze rau qhov ductility thiab dabtsi yog khoov ntawm cov ntawv galvanized. Lub plasticity ntawm galvanized ntawv yog nyob ntawm qhov muaj pes tsawg leeg ntawm substrate thiab cov txheej txheem kev kho cua sov, thiab tseem cuam tshuam los ntawm txheej. Feem ntau hais lus, cov ntawv galvanized muaj cov yas zoo, tuaj yeem muab kev ua haujlwm zoo dua thiab kev ua haujlwm zoo, thiab tsim nyog rau lub sijhawm ua haujlwm xws li stamping, dabtsi yog khoov thiab ncab. Hauv cov ntsiab lus, cov khoom siv hluav taws xob ntawm cov ntawv galvanized yog qhov tseem ceeb rau nws daim ntawv thov hauv ntau qhov chaw. Kev txhim kho ntawm cov khoom siv xws li hardness, lub zog, toughness thiab plasticity tuaj yeem ua rau cov ntawv galvanized ntau ruaj thiab txhim khu kev qha thaum siv.
Yog li ntawd, thaum xaiv thiab siv cov ntawv galvanized, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog nws cov khoom siv kho mob raws li kev siv tshwj xeeb thiab ib puag ncig kom ntseeg tau tias nws tuaj yeem ua tau raws li qhov xav tau siv. Nyob rau tib lub sijhawm, ntxiv dag zog rau kev tshawb fawb thiab kev txhim kho cov khoom siv kho tshuab ntawm cov ntawv galvanized yog qhov tseem ceeb los txhawb txoj kev loj hlob ntawm galvanized ntawv kev lag luam thiab txhawb kev txhim kho cov kev lag luam muaj feem xyuam.
