Galvanized coil yog cov khoom siv hlau nrog cov khoom tiv thaiv corrosion. Nws lub ntsiab feature yog tias nws tsis yooj yim rau corrode. Nws cov txheej txheem galvanized tuaj yeem tiv thaiv cov hlau phaj lub cev thiab txuas ntxiv nws lub neej kev pabcuam. Vim nws muaj zog tiv thaiv corrosion, nws yog dav siv hauv kev tsim kho, metallurgy, khoom siv hauv tsev, tsheb thauj mus los thiab lwm yam haujlwm.
Cov qauv tsim nyog rau galvanized coils:
1. Thickness: Feem ntau hais lus, lub thickness ntawm galvanized coil yog siab tshaj 0.3mm, nrog 0.6mm, 0.8mm, 1mm thiab 1.2mm yog feem ntau siv.
2. Zinc txheej zoo: Zinc txheej zoo yog tus yuam sij rau kev ntsuas kev tiv thaiv corrosion ntawm galvanized coils, feem ntau suav nrog zinc txheej thickness, zinc txheej morphology thiab zinc txheej txheej.
3. Kev pom zoo: Qhov saum npoo ntawm galvanized coil yuav tsum du thiab tsis muaj pitting, wrinkles, npuas thiab lwm yam tsis xws luag.
Yuav ua li cas xaiv qhov tsim nyog galvanized coil thickness:
Kev xaiv thickness ntawm galvanized coils yog txiav txim siab los ntawm kev siv lub sijhawm. Feem ntau hais lus, kev tsim kho kev lag luam siv {{0}} 3-1.2 hli nyias daim hlau; metallurgy, machinery, thiab lub teeb industries feem ntau siv 1.5-4.0 hli nruab nrab daim hlau; hnyav kev lag luam xws li tsheb, nkoj, thawv loj, thiab tsheb ciav hlau locomotives siv 4.5-100mm tuab daim hlau.
Tus qauv rau galvanized coil nyob ntawm lub teb chaws los yog cheeb tsam uas cov kauj yog tsim thiab kev lag luam nws yog npaj rau. Nov yog qee cov qauv siv feem ntau siv rau galvanized coils:
ASTM Cov Qauv:Hauv Tebchaws Meskas, American Society for Testing and Materials (ASTM) muab cov qauv rau cov hlau galvanized. ASTM A653 / A653M yog ib qho kev lees paub dav dav rau kub-dip galvanized steel thiab galvanized steel ntawv.
EN Standards:Hauv Tebchaws Europe, European Committee for Standardization (CEN) muab cov qauv rau galvanized steel. EN 10346 yog tus qauv rau cov khoom siv kub-dip coated steel tiaj tus.
JIS Standards:Nyob rau hauv Nyiv, Japanese Industrial Standards (JIS) tswj ntau yam ntawm steel ntau lawm, nrog rau galvanized txheej. JIS G 3302 yog tus qauv rau kub-dip zinc-coated steel ntawv thiab sawb.
GB Standards:Hauv Suav teb, National Standards of the People's Republic of China (GB) muab cov lus qhia rau galvanized steel ntau lawm. GB / T 2518 yog tus qauv rau kev kub-dip zinc-coated steel nplooj ntawv thiab coils.
ISO Standards:Lub koom haum International rau Standardization (ISO) kuj muaj cov qauv uas muaj feem xyuam rau cov txheej txheem galvanized. TS EN ISO 3575 Cov kev cai rau cov ntawv txias txo cov pa roj carbon steel hauv daim ntawv coil.
