Corrosion thiab kev tiv thaiv ntawm Channel Hlau

Channel Steel yog cov hlau ntev ntev nrog cov zawj zoo nkauj hla-ntu, teej tug rau cov qauv carbon ua hlau rau kev tsim kho thiab tshuab. Nws yog ib ntu cov hlau nrog ib zawj zoo nkauj hla-seem. Channel Hlau yog tsuas yog siv nyob rau hauv tsev qauv qauv, tsheb tsim, thiab lwm yam qauv muaj kev siv, thiab feem ntau siv nrog I-Beams. Vim nws cov qauv sib txawv tshwj xeeb thiab cov yeeb yaj kiab hla kev sib tw, cov hlau feem ntau nyuaj rau cov tshuaj lom neeg thiab ua rau corroded, tab sis nws tsis tuaj yeem corroded nyob rau hauv txhua yam kev mob. Thaum siv cov hlau channel, ntau yam teeb meem yuav ntsib, thiab corrosion yog ib qho ntawm cov teeb meem tseem ceeb dua. Corrosion ntawm Channel Hlau feem ntau tshwm sim los ntawm ob qho laj thawj hauv qab no.

1. Tshuaj lom neeg: roj stains: plua plav, acids, etciet, etc. xeb; Ntau txoj kev yuav ua rau muaj kev puas tsuaj zaj duab xis, txo qis kev tiv thaiv kev tiv thaiv cov hlau channel, thiab yooj yim hnov ​​nrog cov tshuaj me me, ua rau muaj tshuaj lom corrosion thiab xeb.

2. Electrochemical corrosion: Ntaus los ntawm kev sib cuag nrog Carbon Steel seem thiab tsim ntawm lub roj teeb tseem ceeb nrog corrosive media, ua rau hauv electrochemical corrosion; Cov ntawv txuas nrog xeb ntau yam xws li swb swb thiab sib cais rau cov qauv hauv cov xeb hauv nruab nrab, ua rau muaj hluav taws xob hauv lub cev; Lub cev tsis xws luag (undercuts, cov kab nrib pleb, tsis muaj kev sib cav, thiab lwm yam) nyob rau hauv lub roj teeb vuam, thiab tshuaj cais) Cov.

Yog li no, txhua yam kev ntsuas zoo yuav tsum tau coj thaum ua kev ua cov hlau channel ua kom tsis txhob muaj kev tshwm sim ntawm kev kho mob corrosion thiab kev ua haujlwm ntau li ntau tau. Ib txoj kev yog siv txhuas txau txheej. Txau txhuas txheej thiab sealing nrog anti-corrosion txheej tuaj yeem zoo kawg li ntev ntev kev pabcuam lub neej ntawm txheej. Los ntawm theoretical thiab cov tswv yim thov, zinc lossis txhuas txau txheej yog qhov zoo tshaj plaws hauv qab los tiv thaiv corrosion; Cov txheej txheem tawg ua kom muaj zog muaj zog nrog cov hlau substrate, lub neej ntev kev khwv nyiaj tau ntev; Cov txheej txheem txiav co coating txheej hloov tau thiab haum rau kev tiv thaiv ntev ntawm qhov tseem ceeb thiab nyuaj rau kev tuav cov qauv steel, thiab tuaj yeem siv rau ntawm thaj chaw.

Lwm txoj kev yog siv galvanized anti-corrosion tiv thaiv: kub-dip galvanized channel hlau tuaj yeem muab faib rau cov txheej txheem channel. Tom qab xeb tawm, cov steel seem yog raus rau hauv ib daim ntawv zinc ntawm ib ncig ntawm 440-460 ℃ txhawm rau ua kom lub hom phiaj tiv thaiv corrosion. Nyob rau hauv cov huab cua dav dav, nyias thiab ntom txheej ntawm zinc txheej, uas yog qhov nyuaj kom yaj hauv cov dej zinc thiab yog li ntawd ua si qee lub luag haujlwm tiv thaiv ntawm Channel Steel.

Shandong Kungang Hlau Technology Co., Ltd. Cov Khoom Siv Cov Hlau thiab Cov Khoom Muag, Nrog Kev Muag Khoom Siv Hauv Suav Teb Thiab Ntau Lub Tebchaws Thoob Ntiaj Teb. Los ntawm kev ua haujlwm nyuaj ntawm txhua tus neeg ua haujlwm thiab kev koom tes ntawm kev sib koom tes ntawm cov tub rog, peb tuaj yeem ua kom nrawm nrawm, thiab tau nce ntxiv kev txhim kho thiab kev loj hlob. Nrog kev pabcuam zoo thiab cov khoom lag luam zoo, peb tau yeej txoj kev ntseeg siab ntawm peb cov neeg siv khoom.
