Q: Hom dab tsi ntawm galvanized coils?
A: European Cov Qauv Txheej Txheem Europe: DC51D-Z, DC53D-Z, DF
Cov Qauv Qauv Ntawm Japanese Txuj Ci (JIS): SGCC, SGCD
Cov Qauv Qauv ntawm American Standard (ASTM): G90, A653 SS3 SY Qib 33
Q: Dab tsi Q235b thiab Q345B sawv rau?
A: Q235B: Q: Thawj tus tsiaj ntawv ntawm Pinyin ntawm Steel paib lub zog "Qu";
235: Xij lub zog loj dua los yog sib npaug rau 235MPA (ntawm chav tsev kub);
B: Cov qib zoo (qib kawm B txhais tau tias qhov kev cuam tshuam ntawm chav tsev kub yog tsim nyog) .
Q345b: Q: Tib yam li saum toj no;
345: Tshaj tawm lub zog loj dua los yog sib npaug rau 345mPA (ntawm chav tsev kub);
B: Cov qib zoo (tib yam li Q235b, tab sis muaj kev ua tau zoo dua) .
Q: Dab tsi yog qhov txawv ntawm q235b thiab q345b?
A: Lub zog txawv: Q345B yog kwv yees li 50% muaj zog dua Q235b, thiab tuaj yeem txo cov khoom siv nyob hauv tib lub load (thinner thiab sib dua)}
Alloy vs carbon hlau: Q345B ntxiv cov alloys xws li manganese thiab vanadium los txhim kho lub zog thiab kev ua tau zoo tshaj plaws; Q235B yog cov pa roj carbon steel nrog tus nqi qis .
Qhov chaw muaj ib puag ncig: Q345B (cov kev tiv thaiv kub tsawg) yog xaiv rau cov phiaj xwm qhib-huab cua nyob rau sab qaum teb {{4 4}
Q: Dab tsi yog qhov txawv ntawm kub-dip galvanizing (z) thiab electrogalvanizing (ZF)?
A: {1. Cov txheej txheem sib txawv yog kom nyias cov pa roj av yog rau hauv chav sov (txog 450℃yog galvanizing nyob rau hauv chav sov yog galvanizing ntawm electrolysis {}}
2. zinc txheej thickness: kub-dip txheej yog thicker (feem ntau {} g / m²) {5 {5 5}
3.} duab pom ntawm saum npoo ntawm kub-dip galvanizing, du thiab dawb ntawm zinc paj {}}
{{04. Corrosion Kuj: Kub Corrosizing muaj cov kev ua tau zoo dua qub thiab yog qhov tsim nyog rau kev siv sab nraum zoov; Electro-galvanizing muaj cov kev ua tau zoo tshaj plaws ntawm corrosion thiab feem ntau yuav tsum tau siv ua ke nrog lwm cov tshuaj pleev xim.
5. Daim ntawv thov cov chaw thov feem ntau yog siv nyob rau hauv cov khoom siv sab nraum zoov, thaum muaj lwm yam khoom lag luam thiab lwm yam khoom uas xav tau cov chaw zoo {}}
{6. tus nqi sib txawv: kev tsim tau ntau lawm tus nqi hluav taws xob qis dua, thaum tus nqi ntawm electro-galvanizing yog qhov siab dua.
Q: Yuav ua li cas sib txawv Zinc Txheej hnyav hnyav (xws li Z60, Z120) cuam tshuam rau cov xwm txheej siv?
A: Qhov hnyav ntawm cov txheej zinc ntawm lub Galvanized chev ncaj qha cuam tshuam nws corrosion tsis kam thiab siv kev sib txawv yog raws li hauv qab no:
{{0 {}} Z60 (60g / m² ntawm ob sab)
Corrosion Kuj: Nruab Nrab, Haum rau ib puag ncig ib puag ncig
Cov Khoom Siv Hauv Tsev: Sab Hauv Tsev Cov Khoom Siv Hauv Tsev, Cov Ntsal Cable, Ua Cua Ua Si
Cov txiaj ntsig: Tus nqi qis, ua tau raws cov kev xav tau ntawm xeb
Kev Pab Lub Neej: Feem ntau 5-10 xyoo
{{0 {}} Z120 (120g / M² ntawm ob sab)
Corrosion Kuj: muaj zog, haum rau sab nraum zoov chaw
Cov ntaub ntawv raug siv: tsev ru tsev, qauv steel, sab nraum zoov tus saib xyuas
Cov txiaj ntsig: zoo corrosion tsis kam, haum rau cov chaw nag
Kev Pab Lub Neej: Txog 15-25 xyoo
Xaiv cov lus qhia:
Z60 yog ntau tshaj kev lag luam rau cov chaw ib puag ncig zoo tib yam; Z120 yog qhov ua tau zoo tshaj plaws rau kev txhawb nqa sab nraum zoov sab nraum zoov.}
Cov tuab tuab cov zinc txheej, qhov ntau dua tus nqi, thiab tus nqi thiab kev siv yuav tsum tau ua kom lom zem heev.
