Nyob rau hauv dej hiav txwv loj, qhov kev xaiv ntawm cov khoom siv niaj hnub ntawm lub nkoj txawv qhov txawv ntawm qhov av. Siv cov thawv pov tseg piv txwv - feem coob ntawm cov nkoj thauj khoom xaiv rau cov thawv khib nyiab hlau, thiab muaj cov laj thawj zoo tom qab qhov kev xaiv no.
Ua ntej, marine ib puag ncig yog saline heev thiab humid. Ordinary yas los yog ntoo khib nyiab ntim yog nquag corrosion thiab aging. Cov thawv khib nyiab hlau, thaum ua kom zoo- kho, tuaj yeem tiv taus cov ntsev tsuag yaig, ua rau lawv muaj txiaj ntsig zoo dua lwm cov ntaub ntawv.
Thib ob, nkoj kev nyab xeeb yog qhov tseem ceeb. Cov thawv khib nyiab hlau muaj qhov zoo tiv thaiv hluav taws. Yog tias cov luam yeeb uas tsis tau muab tshem tawm los yog cov khoom siv hluav taws xob xaus rau sab hauv, hlau yuav tsis ntes hluav taws thiab kis tau zoo li yas. Qhov no yog qhov tseem ceeb nyob rau hauv qhov chaw kaw thiab txwv txoj kev khiav tawm ntawm lub nkoj, thiab nws ua tau raws li cov cai tswj kev nyab xeeb ntawm International Maritime Organization.
Peb, ships inevitably pob zeb thiab yob thaum voyages. Cov thawv khib nyiab hlau hnyav dua, ruaj khov dua, thiab tsis tshua muaj kev cuam tshuam. Nyob rau tib lub sijhawm, lawv cov qauv ruaj khov tuaj yeem tiv thaiv cov pob thiab cuam tshuam thaum ua haujlwm hauv hiav txwv. Tsis tas li ntawd, muab lub siab-ntse, high-humidity marine ib puag ncig, kev kho saum npoo ntawm cov thawv khib nyiab muaj cov cai tshwj xeeb. Cov khib nyiab loj feem ntau muaj ib qho ntawm ob qhov ua tiav: kub-dip galvanizing lossis zinc-coated steel ntawv nrog hmoov txheej. Lawv lub peev xwm los tiv thaiv corrosion txawv heev - kub-dip galvanizing ua ib txheej denser, muaj zog dua txheej uas muab kev tiv thaiv corrosion zoo heev thiab xeb, zoo dua haum rau marine ib puag ncig thiab muab lub neej ntev kev pab cuam. Nyob rau hauv sib piv, ib zaug ib tug hmoov-coated nto yog chipped los yog khawb, txheej tiv thaiv yog yooj yim puas, thiab cov hlau raug sai rusts thiab corrodes. Xav txog tias cov thawv ntim khoom pov tseg ntawm lub nkoj yuav tsis muaj kev cuam tshuam rau kev khob thiab khawb, kub-dip galvanized hlau khib nyiab ntim yog qhov kev xaiv zoo dua.
Hauv cov ntsiab lus, qhov kev nyiam rau cov khoom siv hlau khib nyiab ntawm cov nkoj thauj khoom tsis yog qhov yuam kev - nws yog qhov kev txiav txim siab tsim nyog raws li cov yam ntxwv ntawm lub nkoj hiav txwv thiab kev nyab xeeb ntawm nkoj. Ntawm cov thawv khib nyiab hlau, qhov kub-dip galvanized version tau pom zoo tshwj xeeb, muab kev tiv thaiv zoo dua rau kev caij nkoj mus ntev.
