1.Dab tsi yog qhov tseem ceeb txaus ntshai?
Cov nplaim hluav taws kub hnyiab heev: Tom qab txias dov, txias-rolled coils tau huv si, zoo heev reactive nto. Txawm hais tias muaj xeb me ntsis -cov yeeb yaj kiab tiv thaiv roj, lawv cov kev tiv thaiv corrosion tseem tsis muaj zog.
Tshuaj corrosion: Muaj ntau yam tshuaj (xws li acids, alkalis, ntsev, thiab oxidants) reacts ncaj qha nrog hlau, rhuav tshem cov passivation los yog roj zaj duab xis rau ntawm qhov chaw, ua rau sai rusting thiab nto puas.
Electrochemical corrosion: Thaum huab cua ntub muaj tshuaj lom neeg (xws li ntsev thiab sulfides), cov tshuaj electrolyte tsim rau ntawm cov hlau, ua kom cov txheej txheem electrochemical corrosion. Qhov kev tiv thaiv corrosion no sai dua li qhov tshwm sim los ntawm dej vapor ib leeg.
2.Dab tsi yog qhov tshwj xeeb ntawm kev phom sij?
Cov kua qaub thiab kua qaub: Piv txwv muaj xws li hydrochloric acid, sulfuric acid, thiab nitric acid. Txawm tias cov kua qaub tsis hloov pauv tuaj yeem ua rau ntawm cov chaw hlau, ua rau muaj qhov hnyav hnyav lossis tsis zoo corrosion.
Alkalis: Piv txwv suav nrog sodium hydroxide (caustic soda). Thaum lawv luv luv -lub sij hawm corrosion ntawm steel yog qhov tsis muaj zog, lawv tuaj yeem ua rau cov roj tiv thaiv cov yeeb yaj kiab thiab txhawb kev xeb hauv qhov chaw ntub dej.
Cov ntsev: Piv txwv suav nrog sodium chloride (lub rooj ntsev) thiab ammonium chloride. Qhov no yog qhov feem ntau insidious thiab muaj kev phom sij. Cov ntsev yog cov hygroscopic heev, tsim cov yeeb yaj kiab ua kua rau ntawm cov hlau thiab ua raws li cov khoom siv hluav taws xob muaj zog, ua rau muaj zog electrochemical corrosion. Cov khoom ntim khoom (xws li ntoo lossis cov hnab ntim khoom uas tau ntsib nrog cov nqaij nruab deg) lossis cov khoom seem de-icing ntsev kuj tuaj yeem ua rau muaj ntsev paug.
Oxidizing tshuaj: Piv txwv suav nrog qee cov tshuaj bleaching thiab tshuaj raw khoom.
Lwm yam tshuaj: Organic kuab tshuaj tuaj yeem ua rau xeb xeb ntawm qhov chaw -cov roj tiv thaiv, ua rau lawv tsis muaj txiaj ntsig.
3.Lub tsev khaws khoom puas yuav tsum tau muab faib ua ib cheeb tsam thiab cais tawm?
Tsim kom muaj ib qho "chaw huv thiab qhuav steel cia chaw."
Qhov chaw no yuav tsum tau khaws cia ntawm qhov chaw muaj kev nyab xeeb los ntawm cov tsev khaws khoom uas khaws cov kua qaub, alkalis, ntsev, chiv, tshuaj zawv plaub hau, tshuaj tua kab, tshuaj reagents, lossis lwm yam tshuaj (zoo tshaj plaws hauv cov tsev sib cais lossis thaj chaw nyob ze).
Txawm tias nyob rau hauv tib lub tsev khaws khoom loj, cov khoom siv lub cev (xws li cov phab ntsa lossis cov teeb meem) yuav tsum tau siv rau kev sib cais, thiab cov tshuab ua pa tawm yuav tsum tau ua kom ntseeg tau.
4.Yuav tswj qhov chaw cia khoom li cas?
Ua kom qhuav: kwv yees cov av noo yuav tsum yog qis dua 50%, thiab yuav tsum tsis pub tshaj 60%. Siv cov dehumidifiers lossis cov khoom siv cua tshuab.
Ua kom huv si: Cov plag tsev thiab phab ntsa yuav tsum huv si thiab plua plav-dawb, tsis muaj tshuaj lom. Kev ua ub no uas yuav ua rau muaj kuab lom yog txwv tsis pub nyob hauv thaj chaw warehouse.
Khaws cov ntim khoom tsis zoo: Khaws cov khoom ntim qub ntawm cov khoom txias- dov coils kom zoo (xws li xeb- ntawv pov thawj, yas zaj duab xis, lossis cov ntawv ntim cov hlau). Cov chaw puas yuav tsum tau kho tam sim ntawd.
5.Txoj kev tswj hwm thiab kev ua haujlwm yog dab tsi?
Kev thauj mus los thiab kev thauj khoom / tshem tawm cov khoom siv (xws li tsheb thauj khoom thiab forklifts) yuav tsum huv thiab tsis muaj tshuaj lom.
Nqa cov tshuaj los yog lawv cov ntim khoob rau hauv qhov chaw cia khoom steel yog nruj me ntsis txwv.
Tsis tu ncua tshawb xyuas lub tsev khaws khoom ib puag ncig thiab qhov chaw ntawm cov hlau, tam sim ntawd txheeb xyuas thiab hais txog cov cim qhia tias muaj kab mob los yog xeb.
