Nrog rau kev txhim kho ntawm kev tsim kho hauv tebchaws, ntau lub tsev tsim kho thiab kev tsim vaj tsev engineering tau ua haujlwm hnyav. Kev txhim kho ntawm qhov project tau ua rau muaj kev nce ntxiv hauv kev siv cov hlau hauv kev ua lag luam. Common galvanized ca hlau / ca hlau kuj yog ib qho ntawm cov ntaub ntawv hlau dav siv hauv engineering tej yaam num.
Dab tsi yog galvanized ca hlau / ca hlau?
▶ Galvanized ca hlau yog ib hom hlau siv rau kev tiv thaiv xob laim thiab hauv av. Nws muaj qhov zoo tiv thaiv corrosion thiab tiv thaiv xeb thiab feem ntau siv los ua tus neeg xyuas pib rau kev tiv thaiv xob laim thiab hauv av.
▶ Galvanized tiaj tus hlau tuaj yeem ua tiav steel, lossis tuaj yeem ua rau hauv cov yeeb nkab galvanized thiab galvanized strips. Raws li cov khoom tiav, galvanized ca steel tuaj yeem siv los ua hoops, cov cuab yeej thiab cov khoom siv tshuab. Nws kuj tseem siv tau los ua cov khoom siv hauv tsev thiab cov escalators hauv kev tsim kho.
Daim ntawv thov ntawm galvanized ca hlau / ca steel hauv engineering tej yaam num muaj ntau haiv neeg. Nws yog cov khoom siv txhim khu kev qha thiab muab kev lees paub rau kev nyab xeeb thiab kav ntev ntawm cov haujlwm engineering.
Dab tsi yog cov teeb meem tshwm sim nrog galvanized ca hlau / ca steel?
▶ Qhov zoo ntawm zinc txheej tsis ua raws li qhov yuav tsum tau ua
Kev tiv thaiv corrosion ntawm galvanized ca hlau nyob ntawm qhov zoo ntawm zinc txheej ntawm nws qhov chaw. Yog tias qhov zoo ntawm zinc txheej tsis ua raws li cov qauv, nws yuav ua rau cov nyhuv tsis zoo los tiv thaiv corrosion thiab yooj yim xeb.
▶ Kev puas tsuaj rau zinc txheej
Thaum lub sij hawm kev thauj mus los, kev teeb tsa lossis kev siv, zinc txheej ntawm galvanized ca hlau yuav raug puas tsuaj, xws li khawb, abrasions, txiav, thiab lwm yam. Cov kev puas tsuaj no yuav txo qhov kev ua haujlwm ntawm cov txheej txheem galvanized thiab yooj yim ua rau xeb.
▶ Cov xim pleev xim tsis tsim nyog
Yog tias vuam tau ua tiav thaum txuas cov hlau galvanized tiaj tus, thiab cov vuam slag yog ncaj qha pleev xim nrog cov xim kho tsis muaj kev kho mob lossis cov xim pleev xim zoo tib yam (xws li cov xim nyiaj) yog siv los kho cov welded qhov chaw, cov nyhuv tiv thaiv corrosion ntawm kev kho. qhov chaw yuav raug txo.
▶ Kev saib xyuas tsis raug
Galvanized ca hlau yuav tsum tau saib xyuas tsis tu ncua. Thaum muaj ntau cov xeb dawb thiab me me ntawm cov xeb liab ntawm qhov chaw, qhov no yog lub sijhawm zoo tshaj plaws rau kev saib xyuas. Yog tias koj xaiv cov xim pleev xim zoo tib yam lossis siv cov xim pleev xim ncaj qha rau ntawm cov xeb, nws yuav ua rau xeb lossis muaj hnub nyoog sai sai hauv lub sijhawm luv luv, yog li cuam tshuam rau nws cov kev ua haujlwm tiv thaiv corrosion.
▶ Ib puag ncig tsis zoo
Kev siv cov galvanized tiaj tus hlau hauv qee qhov chaw tshwj xeeb, xws li cov kua qaub, muaj zog alkali lossis kub kub, yuav ua rau corrosion ntawm zinc txheej thiab txo cov nyhuv tiv thaiv corrosion.
Yog hais tias cov teeb meem saum toj no tshwm sim nyob rau hauv galvanized ca hlau / tiaj tus hlau, yuav ua li cas yuav tsum tau sai sai kho qhov chaw tsim kho?
Txhawm rau kom ntseeg tau tias qhov zoo thiab siv cov nyhuv ntawm cov hlau tiaj tus, peb yuav tsum tau ua cov kev ntsuas tiv thaiv corrosion rau cov teeb meem saum toj no. T
nws cov kev daws teeb meem hauv qab no yog rau koj siv:
☛ nruj me ntsis tswj cov khoom zoo. Xaiv lub galvanized tiaj tus neeg muag khoom nrog kev txhim khu kev qha zoo los xyuas kom meej tias nws ua tau raws li cov qauv thiab cov lus qhia tshwj xeeb kom tsis txhob muaj teeb meem nrog zinc txheej zoo uas tsis ua raws li qhov yuav tsum tau ua.
☛ Ua tib zoo saib cov txheej txheem kev thauj mus los thiab kev teeb tsa. Thaum lub sij hawm kev thauj mus los, galvanized ca hlau yuav tsum tau ua tib zoo thiab ntim kom zoo kom tsis txhob muaj kev puas tsuaj rau cov zinc txheej. Thaum lub sij hawm installation, siv cov cuab yeej tsim nyog thiab cov tswv yim kom tsis txhob khawb, puas thiab lwm yam kev puas tsuaj rau zinc txheej.
☛Choose the appropriate touch-up paint. Use a repair paint with high zinc content. The dry film zinc content is preferably >95%, yog li ntawd cov nyhuv anti-xeb ntawm thaj chaw kho tuaj yeem muab piv rau ntawmkub-dip galvanizing.
☛ Ua haujlwm tsis tu ncua. Tsim cov phiaj xwm kev saib xyuas tsis tu ncua, thiab tshuaj tsuag cov xim zinc-muaj cov tshuaj pleev xim rau lub sijhawm tu zoo tshaj plaws kom ntseeg tau tias xeb-pov thawj lub neej ntawm cov hlau tiaj tus, xws li: GNEEtxias-dip galvanizedxim nrog zinc ntsiab lus ntawm 96%. Tsis tu ncua tshuaj xyuas thiab kho tam sim ntawd qhov chaw puas ntawm zinc txheej kom tiv thaiv corrosion ntxiv.
☛ Xaiv cov kev tiv thaiv tsim nyog raws li ib puag ncig. Nyob rau hauv ib puag ncig tshwj xeeb, xws li cov chaw uas muaj zog acid thiab alkali corrosion, siv galvanized ca hlau / ca steel nto, los yog siv lwm yam kev tiv thaiv ntxiv los txhim kho cov kev tiv thaiv corrosion ntawm galvanized ca hlau.
