1. Ntev npaum li cas tuaj yeem ua tiavgalvanized kaujyuav khaws cia rau hauv lub warehouse?Vim li cas?
A: Nws raug tso cai khaws cia rau peb lub hlis kom tsis txhob oxidation tshwm sim los ntawm kev cia ntev dhau.
2. Dab tsi yog qhov ntev ntev ntawmgalvanized steel ntawv?
Teb: Qhov ntev ntev tsis pub muaj qhov tsis zoo, thiab qhov siab tshaj plaws tsis pub tshaj +6mm.
3. Zinc Paj spangle yog dab tsi?Dab tsi yog qhov me me spangle?Zero spangle?
Teb: Qhov loj spangle yog qhov qub spangle.Raws li cov txheej txheem ntau lawm, lub spangle loj tuaj yeem tsim tau.Txoj kab uas hla ntawm crystal nucleus tsis tsawg dua 0.2mm;txoj kab uas hla ntawm crystal nucleus yog tsawg dua 0.2 hli, uas yog hu ua me spangle.Visually qhia tau.
4. Dab tsi yog txoj cai tiv thaiv ntawmkub-dip galvanizedtxheej?
Teb: Vim tias zinc tuaj yeem tsim cov yeeb yaj kiab uas muaj kev tiv thaiv corrosion zoo ntawm qhov chaw nyob hauv ib puag ncig corrosive.Nws tiv thaiv tsis tsuas yog zinc txheej nws tus kheej, tab sis kuj yog lub hauv paus steel.
5. Dab tsi yog lub hauv paus ntsiab lus ntawm passivation ntawm kub-dip galvanized kauj?
Teb: Kev kho chromate passivation ntawmgalvanized ntawvmuaj peev xwm tsim ib zaj duab xis passivation, thiab nws cov tshuaj tiv thaiv mis yog raws li nram no: Zn + H2GrO4-ZnGrO2 = H2
Lub trivalent chromium nyob rau hauv cov tshuaj passivation tsev neeg yog insoluble nyob rau hauv dej, chemically inactive, thiab ua raws li lub cev pob txha, thaum lub hexavalent chromium yog yooj yim soluble nyob rau hauv dej thiab muaj peev xwm ua si lub luag hauj lwm nyob rau hauv re-passivation thaum lub passivation zaj duab xis yog khawb.Nws muaj cov nyhuv kho ntawm passivation zaj duab xis.Yog li ntawd, nyob rau hauv ib qho kev txwv, cov zaj duab xis passivation tuaj yeem tiv thaiv kev yaig ncaj qha ntawm daim ntawv galvanized los ntawm chav lossis huab cua ntub, thiab zinc txheej ua lub luag haujlwm tiv thaiv.
6. Yuav ua li cas yog cov txheej txheem rau kev soj ntsuam corrosion kuj ntawmkub-dip galvanized ntawv coil?
Teb: Muaj peb txoj hauv kev los ntsuas qhov corrosion kuj ntawm cov ntawv kub-dip galvanized: ntsev tsuag tshuaj ntsuam;kuaj cov av noo;kev kuaj yaig.
7. Vim li cas thiaj li yuav tsum tau kho cov tshuaj tiv thaiv xeb ntawm cov khoom kub-dip galvanized?
Teb: Thaum cov ntawv kub-dip galvanized nyob rau hauv cov huab cua ntub, tshwj xeeb tshaj yog thaum cov huab cua muaj cov kua qaub xws li SiO2, CO2, NO2 thiab NO, qhov saum npoo ntawm cov galvanized txheej yuav sai sai xoob dawb xeb.Cov khoom tseem ceeb ntawm cov xeb dawb yog ZnO thiab Zn (OH) 2. Cov xeb dawb zoo li no tsis tsuas yog cuam tshuam rau lub ntsej muag xwb, tab sis kuj coj teeb meem loj rau kev siv yav tom ntej.
8. Dab tsi yog qhov ua rau xeb dawb ntawmgalvanized kauj?
Teb: Yog vim li cas rau xeb dawb yog: kub-dip galvanizing yog muab tso ua ke nrog rau lwm yam corrosive media xws li acid, alkali thiab ntsev;cov yeeb yaj kiab passivation lossis cov yeeb yaj kiab tiv thaiv raug puas;passivation los yog oiling nyhuv tsis zoo;lub warehouse cia tsis zoo ventilated, Moisture;galvanized ntawv yog txau nrog dej thaum thauj;thauj khoom ntawm qhov kub thiab txias thiab khaws cia ntawm qhov kub thiab txias, tsim condensation.
