1.What yog txheej txheej qauv thiab cov qauv sib xyaw ntawm cov ntawv galvanized?
Txheej Txheej Ntau: Cov txheej txheem galvanized muaj txog 90% -95% zinc (Zn), xws li 5%-siv los tswj cov kev sib xyaw ntawm cov kev daws teeb meem galvanizing). Tus qauv txheej txheej ntawm substrate mus rau saum npoo yog: hlau substrate → Fe-zom cov txheej txheej (muaj quav xim oxide txheej (FEO, Feo, thiab lwm yam).
Microys txheej tsis muaj cov ntawv kub dinc (sib txawv los ntawm cov ntawv loj zoo tib yam Vim tias cov theem ib theem yog tusyees faib tawm, lub tiaj tiaj tiaj tau zoo dua li ntawm unalloy galvanized.
2.What yog lub corrosion tsis kam ntawm cov ntawv galvanized?
Electrochemical kev tiv thaiv mechanism: lub peev xwm electrode ntawm zinc hauv kev tiv thaiv tsis tau qis dua li ntawm cov hlau, thiab kev tiv thaiv kev tua tsiaj ntxiv tseem tuaj yeem tsim; Tab sis vim tias qhov nce hauv cov hlau cov ntsiab lus, cov khoom corrosion yog siab dua li ntawd ntawm cov yeeb yaj kiab txaus, thiab cov corrosion tiv thaiv zaj duab xis, thiab corrosion tiv thaiv zaj duab xis, thiab corrosion tiv thaiv zoo li yog ruaj khov.
Corrosion Cov ntaub ntawv: hauv nruab nrab ntawm ntsev txau lub sijhawm ntawm 50000 teev cia li zoo dua li 2000 teev, thiab zoo dua li ntshiab zinc txheej (nyob ntawm seb muaj kev vam meej).
3.Qhov yog cov neeg kho tshuab thiab ua cov khoom siv ntawm cov ntawv galvanized?
Formancion: Lub hardness ntawm alloyed txheej yog siab tshaj qhov ntawm cov tawv nqaij dawb huv, tab sis vim tias yooj yim kom poob rau thaum lub sij hawm stamping thiab yog haum rau kev sib nqus.
Kev siv vuam: Thaum Vuam Vuam Zinc Txheej Yog Qhov Yooj Yim, thiab cov khoom siv hluav taws xob ntau dua, xws li chaw vuam, xws li vuam vuam, leeg vuam) thiab laser vuam.
Txheej Txheej Txheem: txheej saum npoo oxide txheej ntawm cov txheej txheem tshuaj lom neeg muaj cov xim huv si nrog cov xim ntshiab (xws li cov dej ntshiab zawg, thiab nws feem ntau yuav tsum muaj qhov ntsuas hluav taws xob zoo li cov hlua hluav taws xob.
4.How yog qhov saum npoo ntawm cov ntawv ntawm cov ntawv galvanized tshaj nrog nws siv?
Cov kev kho deg ua ke: phosphat kev kho mob tuaj yeem ua tau ncaj qha los txhim kho kev kho ua ntej kev kho mob; Txawm li cas los xij, vim tsis muaj zinc paj rau saum npoo, cov tsos yog me ntsis tsis zoo nkauj thiab yog qhov tsim nyog rau kev ua haujlwm.
Cov txheej kub siab kuj: cov alloying txheej tau ruaj khov ua haujlwm ntawm qhov kub hauv qab no 200 degree, uas yog qhov tsim nyog rau qhov uas xav tau kev kho cua sov.
5.Qhov yog daim ntawv thov cov xwm txheej ntawm alloy galloized ntawv?
Kev lag luam tsheb: cov nyiaj txiag rau ntau dua 70%, siv rau cov ntawv hauv lub cev, cov tuam txhab tsheb xws li cov khoom lag luam hauv av thiab cov txheej txheem nplaum;
Cov khoom siv hauv tsev thiab cov qauv hlau: qhov uas yuav tsum tau welded, xws li cov pa rov qab thiab cov cua txias-tiv taus cov qauv xws li choj thiab ntim;
Teb tshwj xeeb: marine engineering (yuav tsum tau coj mus rau hauv tus account ob leeg vuam tsis kam thiab vuam), kev ua liaj ua teb machinery (anti-av corrosion).
