{1. Dab tsi yog cov tub ntxhais tseem ceeb uas yuav tsum tau ceev lossis hloov?
Kev puas tsuaj rau lub cev rau txheej txheej, txheej tsis ua tiav tshwm sim los ntawm ib puag ncig corrosion, thiab ntuj poob ntawm txheej vim kev laus
2. Cov laj thawj yog vim li cas cov txheej kev xav tau kev txij nkawm lossis hloov?
Ua rau lub cev puas tsuaj rau txheej txheej: kev puas tsuaj, kev sib txhuam ntawm cov txheej txheem sib dhos) ua rau cov txheej txheem sib xyaw ua ke vim qhov kev kub siab los ua qhov sib txawv ntawm qhov ntsuas kub .
Ib puag ncig corrosion ua rau txheej tsis ua hauj lwm: Sulphide reasing ua nyias cov hmoov av tom qab nonner corrosion .
Seaside / Ntsev Tsuag Ib puag ncig: chloride ions nkag rau txheej txheem zinc, xws li acidic hat hauv kev cob qhia tshuaj lom neeg thiab tiv tauj nrog cov chiv ua liaj ua teb, cov Zinc Txheej tau nrawm nroos
3. Dab tsi yog kev saib xyuas kev ntsuas kom ncua txheej poob?
Kev tu phom txhua xyoo: Siv cov phom dej siab los ntxuav cov ntsev / hmoov av ntawm qhov → txo cov hluav taws xob .
Thaj chaw qhuav nqus cov txheej txheem ntxiv: hauv cov cheeb tsam mus rau dej ntxiv xws li eeeb thiab cov cuab yeej siv hluav taws xob → siv polyurethane toxat (dej tsis kam) {}}
Galvanic Corrosion: Thaum nyob rau hauv kev sib cuag nrog stainless hlau / tooj → ntxiv cov kua mis nylon lossis insulating kua nplaum los thaiv tam sim no .
4. Cov tswv cuab yog dab tsi rau kev tswj hwm cov nqi kho?
Tiv thaiv kev saib xyuas: Khij qhov kev ncaj ncees ntawm zinc txheej tsis tu ncua (xws li tus nqi dawb (xws li tus nqi
Kev xaiv ib puag ncig ib puag ncig: kub-dip galvanizing (zinc txheej cov chaw muaj kuab paug yog muaj kev tiv thaiv txheej los txo cov zaus ntawm kev txij nkawm tom qab kev txij nkawm.
Kev Kho Mob Lub Neej Ua Haujlwm Ua Haujlwm: Rau cov phiaj xwm ntev ntev ntawm 205μm) yog xaiv thaum ntxov ntawm kev kho tus nqi ntawm 40% Txawm li cas los ntawm 40% .
5. Dab tsi yog kev txij nkawm vs .}}}}}}} Txoj kev hloov pauv hloov?
Ntes Zinc Txheej Thickness: Siv cov txheej txheem tuab tuab: Siv cov xim sib nqus<50μm); Evaluate corrosion level: When red rust appears or the base rust is >0.5mm, hloov cov khoom sib xyaw ua ntej;
Cost comparison: When the maintenance cost is >30% ntawm tus nqi ntawm cov tshiab tivthaiv, nws yog kev lag luam ntau dua los hloov nws ncaj qha.
