Yuav ua li cas los tiv thaiv corrosion ua hauj lwm zoo nyob rau hauv steel yeeb nkab Hoobkas
1. Piv nrog rau lwm cov kav dej ib txwm siv, steel yeeb nkab muab steel yeeb nkab muaj lub teeb raw cov ntaub ntawv, siab zog, zoo endurance, muaj peev xwm tiv taus siab sab hauv, rhiab ntau lawm thiab siv, thiab tuaj yeem siv rau kev ntxhov siab lossis hnyav geological.
2. Txawm li cas los xij, cov yeeb nkab steel muaj qhov feem pua ntawm qhov kawg ntawm daim ntawv thov, uas feem ntau tshwm sim los ntawm cov teeb meem ntawm sab hauv thiab sab nraud los tiv thaiv corrosion. Thawj lo lus nug ntawm sab nraud anticorrosion yog qhov tseem ceeb heev, nws cov kev tiv thaiv sab nraud cuam tshuam ncaj qha rau nws lub neej kev pab cuam. Niaj hnub no, sab nraud anticorrosion ntawm cov kav hlau hauv tsev yog qhov tseem ceeb: zais qhov kev coj ua. Cov yeeb nkab steel raug thov kom txhim kho lossis txhim kho kev tiv thaiv sab nraud, thiab qee qhov chaw txhawb kev tiv thaiv cathodic. Txog cov txheej txheem zais ntawm sab nraud anticorrosive feem ntau yog xim xws li roj av asphalt, epoxy thee asphalt, thiab lwm yam, tom kawg tsis yooj yim rau kev kho ntawm qhov kub thiab txias, thiab nyob rau hauv kev lag luam vuam siv ntau cov lus nug, yav tas los siv cov chlorosulfonated polyethylene, vim tias feem ntau cov kuab tshuaj, yooj yim rau pinhole, tsis kam hnav tsis tsim nyog, ntshiab hauv qee qhov chaw tsis siv lawm. Ntawm kev tiv thaiv cathodic ntawm nws cov nyhuv anti-corrosion yog zoo dua, tab sis vim yog xaiv txoj kev txi ntawm anode, nyob rau hauv lub neej yav tom ntej kev khiav hauj lwm yuav tsum tsis tu ncua hloov anode, nce nqi khiav hauj lwm thiab kev khiav hauj lwm.
Ntxiv rau cov lus nug txog kev kho cov phab ntsa sab hauv, cov yeeb nkab steel feem ntau xaiv peb txoj hauv kev: cov xim pleev xim, cov tshuaj khib nyiab, cov cement mortar. Muaj ob lo lus nug nyob rau hauv peb txoj kev: ****** yog lo lus nug ntawm kev sib txuas lub zog ntawm cov txheej txheem anticorrosive thiab cov yeeb nkab steel, thiab cov cement mortar tau hais rau pem hauv ntej. Nyob rau hauv cov txheej txheem anticorrosive thiab resin mortar ob txoj kev yuav tsum tau ua kom huv si tshem tawm xeb ntawm sab hauv ntawm cov yeeb nkab steel ua ntej kev tsim kho, tab sis qhov no yog qhov nyuaj ua tsis tau ploj. Yog li ntawd, cov pob zeb xeb tsim qhov chaw ntawm lub neej yav tom ntej delamination, tsim corrosion thiab scaling; Qhov thib ob, feem ntau ntawm cov kav hlau steel yog welded rau ntawm qhov chaw, thiab kev tiv thaiv corrosion yog nqa tawm tom qab vuam. Nws yuav tsum tau ua manually. Kev ua tau zoo tsis yooj yim rau kev tswj hwm, thiab hais txog cov kav dej me me, vim tias cov neeg ua haujlwm tsis tuaj yeem nkag mus rau kev tsim kho, tsis muaj kev tiv thaiv corrosion. Kuj tsim lub neej yav tom ntej weld kev puas tsuaj zais kev phom sij. Raws li kev txheeb xyuas ntawm ntau qhov kev sib tsoo ntawm cov yeeb nkab tawg, nws feem ntau yog tshwm sim los ntawm corrosion ntawm vuam seams uas tsis zoo.
