Cov hlau galvanized yog ib yam khoom siv hlau uas feem ntau yog coated nrog ib txheej zinc rau ntawm qhov chaw ntawm cov hlau kom ua rau nws tsis kam xeb thiab ntev nws lub neej kev pabcuam. Cov hlau galvanized yog siv dav hauv kev tsim kho, rooj tog, kev tsim tsheb, cov khoom siv fais fab thiab lwm yam teb, thiab muaj qhov tseem ceeb ntawm kev lag luam thiab kev sib raug zoo.
Ua ntej tshaj plaws, qhov tseem ceeb ntawm cov hlau galvanized yog nws txoj kev tiv thaiv corrosion zoo. Vim yog cov txheej zinc, qhov saum npoo ntawm cov hlau tuaj yeem tiv thaiv tau zoo los ntawm kev raug corrosive media xws li huab cua, dej pa, kua qaub thiab alkali, yog li ua kom lub neej ua haujlwm ntawm cov hlau ntev dua. Qhov thib ob, qhov saum npoo ntawm cov hlau galvanized yog du thiab zoo nkauj, yooj yim rau pleev xim thiab ua tiav, thiab tuaj yeem ua tau raws li qhov xav tau zoo ntawm ntau yam lag luam. Tsis tas li ntawd, cov hlau galvanized kuj muaj kev ua haujlwm vuam zoo thiab kev ua haujlwm tsim, tsim nyog rau ntau yam txheej txheem ua tiav, thiab txhim kho kev ua haujlwm ntau lawm thiab cov khoom zoo.
Hais txog kev thov ua lag luam, nrog rau kev txhim kho sai ntawm kev tsim kho, rooj tog, tsheb thiab lwm yam lag luam, qhov kev thov rau cov ntawv galvanized txuas ntxiv mus ntxiv. Tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm cov tsheb fais fab tshiab, kev tsheb ciav hlau ceev ceev, kev thauj mus los hauv nroog thiab lwm yam teb, qhov kev thov rau cov ntawv galvanized yog qhov ceev dua. Tib lub sijhawm, kev nce ntxiv ntawm kev paub txog ib puag ncig kuj tau ua rau muaj kev nce ntxiv ntawm kev thov ua lag luam rau cov khoom galvanized strip nrog kev tiv thaiv corrosion zoo dua.
Txawm li cas los xij, cov khoom siv galvanized kuj ntsib qee qhov teeb meem. Ua ntej tshaj plaws, kev hloov pauv ntawm cov nqi raw khoom yuav cuam tshuam ncaj qha rau tus nqi ntawm cov khoom siv galvanized, thiab kev hloov pauv ntawm cov nqi hlau kuj tseem yuav muaj qee qhov cuam tshuam rau kev lag luam galvanized. Qhov thib ob, kev sib tw ua lag luam yog qhov hnyav, thiab qhov zoo ntawm cov khoom thiab kev tsim kho tshiab tau dhau los ua qhov tseem ceeb rau kev txhim kho kev lag luam. Yog li ntawd, cov chaw tsim khoom galvanized yuav tsum txhim kho cov khoom zoo tas li, txhawb kev tsim kho tshiab, thiab txhim kho kev sib tw ua lag luam.
Feem ntau, cov hlau galvanized, ua ib yam khoom hlau tseem ceeb, muaj kev cia siab dav hauv kev ua lag luam. Raws li ntau yam kev lag luam txhim kho cov khoom zoo thiab kev ua tau zoo, cov khoom hlau galvanized yuav coj ntau lub cib fim kev txhim kho. Tib lub sijhawm, cov tuam txhab yuav tsum txhawb nqa kev tsim kho tshiab thiab txhim kho cov khoom zoo kom hloov kho rau kev hloov pauv ntawm kev thov ua lag luam thiab ua tiav kev txhim kho ruaj khov.
