Tom qab corrosion, steel-cored aluminium stranded hlau yuav tsum tau kho, hloov, los yog tiv thaiv kev ntsuas ntsuas nyob ntawm seb qhov corrosion. Rau me me corrosion, tu thiab daim ntawv thov ntawm hluav taws xob roj yog txaus. Rau corrosion hnyav, cov hlau yuav tsum tau hloov kom ntseeg tau tias muaj kev nyab xeeb ntawm kev xa hluav taws xob.
Txoj kev kho tom qab corrosion
Me me corrosion: Ntawm -kev tu thiab kev tiv thaiv rov qab. Yog tias tsuas yog cov txheej txheem txhuas sab nrauv qhia me ntsis oxidation, blackening, los yog me me ntawm cov deposits dawb, thiab cov tub ntxhais hlau tsis raug, ntawm - kho qhov chaw tuaj yeem ua:
Siv cov paj rwb huv si ntub dej hauv cov roj av los so cov av thiab cov khoom siv corrosion.
Tom qab ntxuav, muab cov roj av sib npaug rau cov xaim saum npoo . 801 cov roj hluav taws xob tsim cov yeeb yaj kiab tiv thaiv kom tsis txhob muaj oxidation ntxiv.
Nws tuaj yeem siv ua ke nrog kev kho tubing rau mechanically txhawb cov cheeb tsam puas.
Nruab nrab corrosion: Kho tubing los yog ua ntej -stranded hlau reinforcement. Thaum aluminium strands pom pom tseeb corrosion me ntsis lossis localized strand breakage tab sis tsis cuam tshuam rau kev ncaj ncees ntawm cov tub ntxhais hlau:
Siv aluminium kho tubing los yog ua ntej - hlua khi rau crimp thiab ntxiv dag zog rau qhov puas. Ua ntej kho, kom huv si tshem tawm corrosion thiab siv hluav taws xob roj los txhim kho conductivity thiab corrosion kuj.
Corrosion hnyav: Hloov tag nrho tus neeg xyuas pib. Yog hais tias cov tub ntxhais hlau yog xeb, cov txheej galvanized tau tev tawm ntawm thaj chaw loj, lossis cov neeg kho tshuab lub zog tau poob qis (piv txwv li, qhov ntsuas txoj kab uas hla tau qis dua 0 mm). Yog tias cov hlau yog 0.1mm tuab, ces:
Tag nrho cov seem ntawm cov hlau yuav tsum tau txiav thiab hloov; Kev kho ib nrab tsis tau txais.
Nws raug nquahu kom siv cov khoom siv corrosion tshiab-cov khoom tiv taus xws li txhuas-clad steel tub ntxhais aluminium stranded hlau los yog tshav kub-cov hlau alloy hlau los hloov.
Kev txhim kho kev tiv thaiv zoo: Hauv cov cheeb tsam uas muaj kev xeb (xws li thaj chaw ntug dej hiav txwv thiab thaj chaw muaj kev lag luam), ntxiv rau kev kho, qib kev tiv thaiv tag nrho yuav tsum tau txhim kho:
Coated uncorroded seem ntawm xaim nrog tiv thaiv -corrosion roj kom ua tiav ntev - cais tawm. Siv ZnAlMg alloy coated steel core los yog NiPSiC composite txheej tshuab los txhim kho corrosion kuj. Ua ntej aluminium-clad steel core structures kom tsis txhob muaj teeb meem electrochemical corrosion.
