1.Dab tsi yog qhov teeb meem tseem ceeb thiab cov txheej txheem hauv qab ntawm cov tshuaj?
Direct Tshuaj Corrosion:
Acids, Alkalis, thiab ntsev: Txawm tias muaj pes tsawg feeb ntawm splashes los yog volatiles tuaj rau hauv kev sib cuag nrog steel coil nto tuaj yeem ua rau cov txheej txheej passivation ncaj qha, ua rau pitting, xeb, lossis tsis muaj xim. Cov piv txwv muaj xws li corrosive hydrochloric acid, sulfuric acid, sodium hydroxide, thiab sodium chloride (ntsev).
Oxidizing Agents: Cov tshuaj xws li tshuaj chlorine thiab tshuaj dawb ua kom cov tshuaj tiv thaiv oxidation ntawm cov hlau.
Electrochemical corrosion kuj:
Thaum cov hlau coil nto adsorbs cov tshuaj muaj electrolytes (xws li ntsev thiab kua qaub), micro- roj teeb tuaj yeem tsim nyob rau hauv qhov chaw ntub dej, ua kom cov txheej txheem corrosion zoo heev.
Surface Contamination thiab Secondary Processing Defects:
Qee cov tshuaj (xws li roj, organic solvents, thiab resin volatiles) tuaj yeem tsim nyuaj -- tshem cov roj films lossis adhesions ntawm qhov chaw, ua rau muaj teeb meem loj xws li txheej txheej tev thiab vuam porosity thaum lub sij hawm tom qab pleev xim, vuam, lossis electroplating.
2.Dab tsi yog cov qauv tshwj xeeb thiab cov kev cai rau kev cais tshuaj?
Zoning nruj: Cov cheeb tsam yuav tsum tau cais tawm ntawm lub cev los ntawm cov chaw khaws cov kua qaub, alkalis, ntsev, kuab tshuaj, roj, tshuaj ntxuav, thiab lwm yam tshuaj, qhov zoo tshaj plaws nyob rau hauv cais warehouses lossis vaj tsev.
Volatile Gas Control: Kev khiav hauj lwm uas yuav ua rau cov roj corrosive (xws li electroplating thiab pickling) yog txwv tsis pub sab hauv thiab ib ncig ntawm lub warehouse.
3.Yuav tswj cov av noo li cas?
Cov av noo txheeb ze: Nws raug nquahu kom khaws nws qis dua 50% rau lub sijhawm ntev. Lub tshuab dehumidifier tuaj yeem siv tau, thiab lub tsev khaws khoom yuav tsum tau muab kaw.
High humidity ua raws li ib tug catalyst rau corrosion, thiab thaum ua ke nrog chemical pollutants, nws muaj peev xwm exacerbate qhov kev puas tsuaj ntau zaus.
4.Peb tuaj yeem ua kom huv si li cas?
Kev tiv thaiv plua plav thiab particle: Lub tsev khaws khoom yuav tsum raug kaw kom tsis txhob muaj cov khoom hnyav xws li plua plav, thee tshauv, thiab xuab zeb los ntawm ntog thiab ua rau muaj kev cuam tshuam lossis khawb thaum ua haujlwm tom ntej.
5.Dab tsi yog qee qhov kev pom zoo rau kev ua haujlwm ntawm cov khoom lag luam?
Warehouse Location and Layout: Lub warehouse yuav tsum nyob rau hauv qhov chaw siab, qhuav, upwind ntawm cov pa phem xws li cov nroj tsuag tshuaj, electroplating nroj tsuag, thiab pickling rhiav.
Kev Tshuaj Xyuas Tom Qab: Thaum tuaj txog ntawm cov hlau coils, tshuaj xyuas cov ntim khoom puas tsuaj, cov roj stains, lossis dej stains. Cais tawm thiab daws tej teeb meem tam sim ntawd.
Tsim Cov Txheej Txheem Tswjhwm: Kom meej meej txwv tsis pub nqa cov tshuaj lossis cov kua dej tsis pom zoo rau hauv qhov chaw cia. Tsim kom muaj kev tu vaj tse, ua kom tu tsis tu ncua, tab sis tsis txhob siv cov mops ntub dej lossis cov tshuaj ntxuav uas yuav khaws cov tshuaj lom neeg.
Kev Saib Xyuas thiab Kev Teev Tseg: Nruab cov ntsuas kub thiab cov av noo hauv lub tsev khaws khoom kom tsis tu ncua saib xyuas thiab sau cov ntaub ntawv rau lub sijhawm ceeb toom thiab tuav thaum muaj xwm txheej ib puag ncig.
Kev Npaj Thaum Muaj Xwm Ceev: Tsim cov phiaj xwm xwm txheej ceev nrog kev sib cais kom meej, qhia, thiab tuav cov txheej txheem thaum muaj cov tshuaj lom neeg tsis sib haum los yog nchuav mus rau thaj tsam steel coil.
