Astm A653 galvanized steel ntawv yog tsim los ntawm pre-plating daim ntawv raws li specification ASTM A653.
Cov txheej txheem kub-dip txheej txheem txuas ntxiv raws li ASTM A653, Specification rau Steel Sheet, Zinc-Coated (Galvanized) los yog Zinc-Iron Alloy-Coated (Galvannealed) los ntawm Cov Txheej Txheem Kub-Dip, yog ib txoj hauv kev siv los ua cov khoom siv ua ntej. mus fabrication.
Hauv cov txheej txheem no, cov hlau tau dhau los ua cov hlua txuas txuas ntxiv los ntawm kev tsim khoom thiab mus rau hauv ib da dej ntawm zinc molten ntawm speeds mus txog 600 ko taw ib feeb. Thaum cov khoom raug tshem tawm ntawm lub da dej, cov cua kub siab yog siv los tshem tawm cov zinc molten ntau dhau los tsim kom muaj cov txheej txheem zoo sib xws. Tom qab ntawd, cov hlau yog txias thiab dov rau hauv cov coils loj rau kev tsim khoom. Niaj hnub no, cov txheej txheem txuas ntxiv yog siv los ua xya ntau yam khoom kub-dip coated, suav nrog galvanized (zinc), galvannealed (90-92% zinc / 8-10% hlau alloy), ob alloys ntawm zinc. thiab txhuas (55% aluminium / 45% zinc alloy thiab 95% zinc / 5% aluminium alloy), ob lub aluminium raws li cov alloys (100% aluminium, 89-95% aluminium / 5-11% silicon alloy), thiab terne txheej (85-97% lead / 3-15% tin alloy).
ASTM A653 Cov Khoom Siv Hluav Taws Xobqhov zoo
Nyias-coated kub-dip galvanized cov ntaub ntawv muaj peev xwm vuam zoo heev thiab kev ua haujlwm. Nws tuaj yeem siv los ntawm kev siv dav dav mus rau kev sib sib zog nqus kos duab thiab tuaj yeem xaiv raws li lub hom phiaj.
Thick galvanized kub-dip galvanized cov ntaub ntawv muaj corrosion kuj zoo heev. Ntau daim ntawv thov tuaj yeem siv los ntawm kev xaiv spangles thiab tom qab ua haujlwm.
Kub-dip alloy steel tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev tab sis kuj muaj qhov zoo adhesion thiab ductility ntawm txheej, yog li nws tuaj yeem ua haujlwm zoo heev. Qhov kom zoo dua yog tias nws muaj qhov zoo nkauj zoo nkauj thiab tuaj yeem siv rau cov ntawv thov qhov chaw uas tsis tau pleev xim rau.
ASTM A653 sib npaug
ASTMA653 yog tus qauv Asmeskas, uas yog sib npaug rau Japanese JIS G 3302, Europe EN 10346. Kub-dip galvanized steel ntawv nrog txheej tuab ntawm 0.3 oz / square inch. Cov khoom muaj kev qhia dav dav.
