Cov hlau tsis xeb bollardsfeem ntau tsis xeb vim tias lawv cov khoom tseem ceeb muaj chromium, uas reacts tshuaj lom neeg nrog oxygen los tsim ib txheej chromium oxide ntom ntom, uas

tiv thaiv kev oxidation ntxiv ntawm cov hlau thiab yog li ntawd muaj zog tiv thaiv corrosion. Cov txheej chromium oxide ntom no tuaj yeem tiv thaiv qhov chaw ntawm cov hlau tsis xeb los ntawm feem ntau ib puag ncig

kev yaig, ua rau nws tiv thaiv corrosion.

Txawm li cas los xij, qhov chaw dub ntawm cov hlau tsis xeb kuj tseem yuav tshwm sim nyob rau hauv qee qhov xwm txheej. Cov laj thawj tseem ceeb rau qhov dub ntawm qhov chaw ntawmcov hlau tsis xeb bollardstej zaum yuav yog:

Cov pa phem ntawm qhov chaw:Yog tias qhov chaw ntawm cov hlau tsis xeb raug rau lossis tso cov khoom tsis huv rau lub sijhawm ntev, xws li hmoov av, av qias neeg, roj, thiab lwm yam, ib txheej av qias neeg yuav tsim, ua rau

qhov chaw kom tig dub.

Kev kho oxide:Hauv qee qhov chaw tshwj xeeb, qhov chaw ntawm cov hlau tsis xeb yuav raug rau qee cov oxides, xws li xeb lossis lwm yam hlau oxides, uas tuaj yeem ua rau

qhov chaw kom dub.

Cov tshuaj tiv thaiv:Nyob rau hauv kev ua ntawm qee cov tshuaj lom neeg, kev tshuaj tiv thaiv tshuaj lom neeg yuav tshwm sim rau ntawm qhov chaw ntawm cov hlau tsis xeb, ua rau qhov chaw tig dub. Piv txwv li, kev tshuaj tiv thaiv

tej zaum yuav tshwm sim tom qab kov cov tshuaj uas muaj zog tshuaj xws li kua qaub thiab alkalis.

Kub ib puag ncig:Nyob rau hauv qhov chaw kub siab, oxidation yuav tshwm sim rau ntawm qhov chaw ntawm stainless hlau, ua rau qhov chaw tig dub.

Raucov hlau tsis xeb bollards, kev ntxuav thiab saib xyuas tsis tu ncua yog qhov tseem ceeb heev. Koj tuaj yeem siv cov tshuaj ntxuav mos mos thiab daim ntaub mos mos los tshem tawm cov av thiab roj ntawm qhov chaw. Tsis tas li ntawd,

thaum sivcov hlau tsis xeb bollardsnyob rau hauv cov chaw tshwj xeeb, yuav tsum tau ceev faj kom tsis txhob kov cov tshuaj lom neeg thiab ua kom qhov chaw qhuav thiab huv si kom ntev lub neej kev pabcuam ntawm

cov hlau tsis xeb bollards.
