Lub steel qauv yog ua los ntawm steel raw cov ntaub ntawv. Nws qhov teeb meem ntau dua yog tias nws yooj yim heev rau xeb. Nyob rau hauv tag nrho cov txheej txheem ntawm steel qauv kev tsim kho, tus txheeb ze antirust kev kho mob thiab kev siv tshuab yuav siv tau, tab sis nws tsis tuaj yeem tiv thaiv corrosion ntawm nto ntawm cov khoom hlau. Tom qab ntawd yuav ua li cas txhawm rau tiv thaiv xeb thaum xeb?
Feem ntau hais lus, muaj plaub txoj hauv kev los daws cov xeb ntawm qhov chaw ntawm cov qauv hlau, uas yog, kev tsim khoom siv, cov cuab yeej siv tshuab, cov tshuaj lom neeg thiab cov nplaim taws. Cov tshuaj xuas tes ua yog ib txoj hauv kev yooj yim heev, tab sis kev ua haujlwm siab thiab cov txiaj ntsig ua haujlwm tsis muaj zog. Nws tsuas yog tsim nyog rau kev kho me me -kev tiv thaiv kab mob. Nws yog tsuas yog siv cov cuab yeej tshwj xeeb xws li riam grey, txhuam steel thiab cov ntaub xuab zeb kom tshem tawm xeb los ntawm tes khob thiab khawb.
Cov cuab yeej siv kho tshuab yog hais txog kev siv qee qhov hluav taws xob lossis tilting cov cuab yeej tshwj xeeb kom tshem tawm cov xeb ntawm cov qauv hlau. Nyob rau hauv cov kev daws teeb meem ntawm cov cuab yeej siv tshuab, cov cuab yeej tshwj xeeb tshaj yog cov txhuam hluav taws xob thiab hluav taws xob xuab zeb, thiab lwm yam. Cov txheej txheem no yog txoj kev tshem tawm xeb zoo tshaj plaws nrog kev tsim kho engineering zoo heev, kev siv yooj yim thiab kev ua haujlwm siab. Txawm li cas los xij, peb ua siab zoo ceeb toom cov neeg siv khoom tias lawv yuav tsum tau them nyiaj rau tsis txhob tawg ntawm daim tawv nqaij ntawm cov ntaub ntawv hlau thaum lub sijhawm ua haujlwm.
Organic chemical solution actually refers to the solution of metal surface rust with acid-base aqueous solution, that is, chemical change with hydroxide. The flame solution refers to the use of gas welding gun to eliminate rust. When applying this kind of method, we must pay attention to the same way as mechanical equipment. We can't burn through the surface of metal materials, otherwise the steel structure is very prone to thermal deformation.
