Raws li kev tsim kho steel, raws li kev txiav txim siab tus nqi thiab tsis-punching yuav tsum, kev siv cov CQ zoo tib yam steel rau kev kho mob nyuaj lossis ib nrab los txhim kho cov paib muaj zog yeej ib txwm yog thawj qhov kev xaiv rau kev txhim kho kub-dip galvanized steel rau kev tsim kho , tab sis rau kev ua cov txheej txheem formability Yuav tsum muaj siab, tag nrho cov txheej txheem nyuaj tsis tuaj yeem ua raws li lub zog loj, tsis tshua muaj txiaj ntsig piv steel ntau lawm.
Plating alloying
Kub-dip galvanizing yog qhov feem ntau siv xim xim txheej xim. Ua kom cov tuab tuab ntawm txheej txheej yog qhov tseem ceeb txhais tau tias txhawm rau txhim kho xeb. Txawm li cas los xij, nce qhov tuab ntawm txheej ntxiv nce tus nqi, thiab cov khoom zoo dua tsis yooj yim los tswj. Ntxiv nrog rau qhov kev ua tiav ntawm thoob ntiaj teb zinc cov khoom siv, ntau yam kev txhim kho corrosion. Zoo alloy cov khoom lag luam tuaj mus rau hauv ua.
Qee qhov ntawm cov yam ntxwv ntawm cov alloy galvanizing yog qhov sib ntxiv ntawm qee cov ntsiab lus alloying, uas ua tau zoo dua txhim kho qhov tsis kam tiv thaiv cov khoom lag luam uas tsis ua rau qhov hnyav ntawm cov xim txheej (lossis txawm tias txo qhov hnyav ntawm txheej). Cov tshuaj tiv thaiv corrosion ntawm alloy txheej yuav muab ob npaug piv nrog dog dig kub zinc. -10 zaug.
Cov tshuaj pleev cov xim siv ntau yog siv ntau cov ntawv txhuas galvanized (5% Al-95% Zn), aluminium zinc plating (55% Al-43.5% Zn-1.5% Zn) thiab txhuas-zinc-magnesium plating (6%). Al-3% Mg ntawm 91% Zn) thiab cov zoo li.
Ntau yam xim txheej txheej ntau
Cov txheej txheej txheej, ntau hom qauv thiab kev siv ntawm cov xim coated steel ntawv yog raws li nram no:
Type Txheej txheej: cov khoom zoo nkauj polyester, 矽 hloov kho polyester, huab cua tiv thaiv polyester, polyvinylidene fluoride thiab lwm yam.
▪ Kev co ua haujlwm: antistatic, tua kabmob, tiv thaiv tus kheej, rwb thaiv tsev kub, thiab lwm yam.
Structure Coating tus qauv: 2/1, 2/2, 3/2, thiab lwm yam.
▪ Kev ua cov txheej txheem tom qab: hlau npuag thiab luam ntawv.
Siv: kev tsim kho, khoom siv hauv tsev, qhov rooj thiab qhov rais thiab tsheb thauj mus los.
