Cov pa roj carbon steel yog cov khoom siv nyiaj txiag tshaj plaws rau kev txhawb nqa kav dej.
Raws li lub hauv paus ntsiab lus ntawm kev ua tau raws li qhov yooj yim lub zog thiab cov qauv kev cai, carbon steel (xws li Q235B) yog tus nqi tshaj plaws - kev xaiv zoo rau cov kav dej txhawb kev lag luam vim nws cov khoom siv qis qis thiab cov txheej txheem tsim tawm. Nws tus nqi feem ntau qis dua stainless hlau, aluminium alloy, lossis hlau alloy:
Tus nqi ntawm cov pa roj carbon zoo tib yam cov kav dej tuaj yeem qis li ¥ 1.0 / thooj, thaum kub -dip galvanized carbon steel txhawb cov kav dej yog kwv yees li ¥ 22.0 / meter, dav siv hauv tsev cog khoom, kev txhawb nqa hauv tsev, thiab lwm yam xwm txheej uas yuav tsum muaj kev tiv thaiv corrosion tsis siab.
Txawm hais tias cov pa roj carbon steel nws tus kheej yuav ua rau xeb, galvanizing tuaj yeem txhim kho corrosion rau qee yam thiab txuas ntxiv kev pab cuam lub neej, thaum tseem tswj hwm tus nqi qis.
Hauv loj - kev yuav khoom lossis cov haujlwm ib ntus, qhov txiaj ntsig kev lag luam ntawm cov pa roj carbon steel cov kav dej yog qhov pom tseeb dua, tshwj xeeb tshaj yog tsim rau cov haujlwm lag luam nrog cov peev nyiaj tsawg thiab ib puag ncig qhuav tsis muaj tshuaj lom neeg muaj zog.
Hauv kev sib piv:
Stainless hlau txhawb cov kav dej (xws li 304) feem ntau raug nqi tshaj ¥ 25.0 ib meter, ob peb zaug tus nqi ntawm cov hlau. Thaum lub sij hawm ruaj khov, lawv xav tau kev nqis peev pib siab.
Aluminium alloy txhawb cov kav dej yog lub teeb yuag thiab corrosion-resistant, tab sis tseem kim dua. Lawv feem ntau yog siv rau hauv qhov hnyav- cov ntawv thov tshwj xeeb thiab tsis tshua muaj nqi.
27SiMn alloy steel hydraulic txhawb cov kav dej, thaum muaj zog, feem ntau yog siv rau hauv siab -load mechanical structures. Tus nqi tshaj ¥ 5000 ib tuj, lawv tsim nyog rau cov ntawv thov kev lag luam hnyav thiab tsis muaj kev lag luam dav dav.
