1.Vim li cas galvanized coils tsim nyog rau kev kho kom zoo nkauj ntug strips?
Zoo Flexibility thiab Processability:
Lub substrate ntawm galvanized coils yog txias - dov qis - carbon steel, uas yog inherently muaj ductility zoo heev.
Tom qab kub-dip galvanizing, zinc txheej tsim ib daim ntawv cog lus metallurgical nrog cov hlau substrate. Tsuav yog cov zinc txheej adhesion thiab yas zoo txaus (raws li nyob rau hauv ib txwm ua lag luam coils), nws tuaj yeem tiv thaiv kev ua haujlwm xws li ntug dov, dabtsi yog khoov, thiab stamping yam tsis muaj loj - nplai zinc txheej tev lossis tawg.
Muaj zog Corrosion Resistance:
Hniav strips feem ntau yog siv sab hauv tsev thiab sab nraum zoov, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig sab nraum zoov (xws li lub tsev sab nrauv phab ntsa trims, ru tsev ntug, thiab lwm yam) uas lawv raug tshav ntuj thiab los nag.
Zinc txheej ua ntej ua ib tug sacrificial anode, tiv thaiv lub hauv paus steel substrate los ntawm corrosion. Txawm tias me me nto khawb, qhov kev tiv thaiv no tseem nyob. Qhov no ua kom lub ntsej muag zoo nkauj lub neej ua haujlwm ntev thiab tiv thaiv xeb.
Tus nqi siab -effectiveness:
Piv nrog rau lwm yam corrosion-cov hlau tsis muaj zog xws li stainless hlau thiab txhuas alloys, galvanized coils tsis tshua kim, muab tus nqi sib tw heev -kev ua tau zoo.
2.Thaum siv cov galvanized coils los ua cov hniav zoo nkauj, yuav xaiv zinc txheej thickness li cas?
Lub hauv paus ntsiab lus: Cov txheej txheem tsim ntau dua (qhov me dua lub vojvoog curling), qhov zoo dua cov zinc txheej adhesion thiab plasticity yuav tsum raug xaiv. Feem ntau, lub thinner zinc txheej, qhov zoo dua qhov formability.
Kev pom zoo: Rau kev ua haujlwm curling dav dav, qhov nruab nrab zinc txheej tuab yog txaus, xws li Z60-Z100 (ie, ob -sab zinc txheej hnyav 60-100g / m²). Cov zinc txheej tuab heev (xws li Z180 thiab saum toj no) ua rau muaj kev pheej hmoo ntawm micro-cracks thaum khoov hnyav, tab sis feem ntau tsis cuam tshuam rau lawv cov corrosion kuj.
3.Dab tsi yog qhov yuav tsum tau ua rau cov khoom siv substrate thiab cov khoom siv kho tshuab?
Hom hlau siv rau cov hlua dai kom zoo nkauj yuav tsum tau xaiv raws li qhov kev ntxhov siab nws yuav raug. Rau kev kho kom zoo nkauj ntshiab, tsis yog -tshuaj dov ntug strips, feem ntau DX51D (feem ntau siv) los yog DC01 (txias- dov qis- carbon steel) yog txaus. Yog hais tias yuav tsum muaj ib theem ntawm lub zog thiab kev txhawb nqa, lub zog steel qib siab dua tuaj yeem txiav txim siab.
4.Dab tsi yog qhov yuav tsum tau ua rau kev kho deg?
Spangle-dawb / me me spangle: Qhov no yog qhov kev xaiv zoo tshaj plaws vim tias nws lub ntsej muag zoo ib yam, ua rau nws tshwj xeeb tshaj yog haum rau kev txau tom qab thiab ua rau cov xim zoo nkauj thiab zoo nkauj.
Smooth nto: Galvanized coils uas tau ua tiav kev kho kom zoo muaj qhov smoother, tshem tawm cov qoob loo, txhim kho formability, thiab tsis tshua muaj kev txhim kho Lüders bands (cov kab mob), ua rau lawv zoo tagnrho rau kev ua tau zoo - zoo nkauj zoo nkauj strips.
5.Dab tsi yog qhov yuav tsum tau ua rau kev ua haujlwm tom ntej thiab kev sib txuas?
Txiav: Laser txiav thiab CNC xuas nrig ntaus thiab shearing tuaj yeem ua tiav cov txiaj ntsig zoo.
Vuam: Zinc vapor yog tsim thaum lub sij hawm vuam ntawm txheej galvanized, uas cuam tshuam rau vuam zoo thiab kev noj qab haus huv ntawm cov neeg ua haujlwm. Cov txheej txheem tshwj xeeb (xws li MIG vuam nrog cov kev hloov kho) thiab qhov cua zoo yuav tsum tau ua. Hniav strips feem ntau txuas nrog mechanically (clamps, riveting, adhesive) thiab vuam tsis tshua muaj.
