1.Dab tsi yog cov qauv thiab cov teebmeem ntawm laser engraving?
Galvanized steel ntawv feem ntau yog tsim los ntawm ob txheej:
1. Txheej txheej: zinc (galvanized txheej).
2. Cov khoom siv hauv paus: txias-rolled steel ntawv.
Thaum lub sij hawm laser engraving, los ntawm precisely tswj lub laser lub zog thiab scanning ceev, zinc txheej yuav vaporized thiab tshem tawm los ntawm ib tug tshwj xeeb cheeb tsam yam tsis muaj kev puas tsuaj rau lub hauv paus steel substrate. Vim zinc yog silvery-dawb thiab steel substrate yog grey-dub, tshem cov zinc txheej qhia lub grey -dub substrate, tsim ib tug ntshiab dub- dawb sib piv.
Lub teeb engraving: Tsuas yog cov zinc txheej raug tshem tawm, nthuav tawm cov grey -dub steel substrate. Qhov no yog qhov tshwm sim ntau tshaj plaws thiab xav tau, muab qhov zoo sib xws thiab muaj kev cuam tshuam tsawg kawg rau kev tiv thaiv corrosion.
Sib sib zog nqus engraving: Ntau lub zog laser tuaj yeem tsis tsuas yog vaporize zinc txheej tab sis kuj yaj feem ntawm cov hlau substrate. Qhov no tuaj yeem ua rau:
Cov xim cim yuav dhau los ua sib dua (molten steel yuav pom lub teeb).
Microscopic slag thiab unevenness yuav tsim.
Hnyav impairing corrosion kuj ntawm cheeb tsam.
2.Yuav ua li cas xaiv lub laser?
Fiber laser: Qhov no yog qhov kev xaiv zoo tshaj plaws. Fiber lasers (wavelength kwv yees li 1060nm) muaj qhov nqus siab heev rau cov ntaub ntawv hlau thiab tshwj xeeb tshaj yog zoo - haum rau cov ntaub ntawv xws li galvanized sheet hlau. Lawv muab cov txiaj ntsig zoo xws li cov kab teeb pom kev zoo, siab precision, kev kub ceev, thiab kev txij nkawm qis.
CO2 lasers: Qhov no kuj tuaj yeem siv tau, tab sis lawv qhov nqus tau rau cov hlau yog qhov tsawg, xav tau lub zog siab dua, thiab lawv muaj ntau dua rau cov cim slag. Lawv cov ntug zoo yuav tsis zoo li cov fiber ntau lasers.
3.Yuav ua li cas optimize tsis?
Fais fab: nruab nrab mus rau qis zog yuav tsum tau. Lub zog ntau dhau tuaj yeem hlawv los ntawm zinc txheej thiab ua rau cov hlau substrate puas.
Ceev: Scanning ceev yuav tsum ceev. Kev kub ceev ua ke nrog lub zog tsim nyog tuaj yeem vaporize zinc txheej ntau dua li yaj nws, ua rau cov npoo huv si.
Zaus: Kho qhov zaus kom tsim nyog kom pom "qhov chaw qab zib" uas tshem tawm cov zinc txheej tsis muaj cua sov.
Fill spacing: Qhov kev ncua deb ntawm cov kab sau yuav tsum tau teem kom tsim nyog. Kev sib ze dhau lawm yuav ua rau cov cua sov sib xyaw, thaum sib sib zog nqus heev yuav ua rau tsis tiav.
4.Dab tsi yog cov teeb meem tseem ceeb thiab teeb meem?
Zinc Vapor thiab Spatter: Zinc muaj qis melting thiab boiling point (boiling point kwv yees li 907 degree). Thaum lub sij hawm laser irradiation, zinc vaporizes sai heev, muaj peev xwm nqa zinc hais nrog nws. Cov khoom no condense thiab tsim nyuaj-kom- tshem zinc slag nyob ib ncig ntawm thaj chaw engraved, cuam tshuam rau kev zoo nkauj thiab kev huv.
Surface Reflection: Cov ntawv galvanized tus du nto muaj qhov cuam tshuam siab, uas qhia txog qee lub zog laser. Yog li ntawd, cov khoom siv yuav tsum muaj kev tiv thaiv zoo.
Corrosion puas: Qhov no yog qhov kev txwv loj tshaj plaws. Lub engraved cheeb tsam poob lub sacrificial tiv thaiv ntawm zinc txheej, ua rau nws muaj peev xwm pib taw tes rau xeb. Qhov no yuav tsum tau ua tib zoo xav yog tias cov khoom siv nyob rau hauv ib puag ncig corrosive heev.
Thaum tshav kub kub-Qhov cuam tshuam: Lub tshav kub tsim los ntawm lub laser tuaj yeem ua rau muaj kev hloov pauv microstructural nyob rau hauv zinc txheej ntawm ntug ntawm lub engraving, uas yuav cuam tshuam me ntsis rau nws cov kev ua tau zoo.
5.Dab tsi yog cov ntsiab lus ntawm qhov zoo thiab qhov tsis zoo?
Qhov zoo:
Permanent: Lub cim yog ruaj khov thiab tsis tuaj yeem tshem tau yooj yim.
High Precision: Muaj peev xwm engraving zoo heev QR codes, barcodes, ntawv nyeem, thiab complex qauv.
Tsis yog -Kev Sib cuag: Tsis muaj lub cev siab lossis deformation yog siv rau cov ntaub ntawv.
High Efficiency: High engraving ceev, haum rau hauv - kab cim ntawm cov kab ntau lawm.
Environmentally Friendly: Tsis tas yuav tsum muaj cov khoom siv xws li number case, ua kom huv si.
Qhov tsis zoo:
Localized poob ntawm corrosion kuj: Qhov chaw engraved yog raug rau xeb.
Cov txheej txheem yooj yim debugging: Parameters yuav tsum tau rov kuaj dua rau qhov sib txawv zinc txheej thicknesses thiab deg tej yam kev mob (xws li, du tiav, tsis muaj spangles, thiab lwm yam).
Muaj peev xwm spatter: Impacts aesthetics thiab huv si ntawm lub cim.
Cov Khoom Siv Peev Xwm: Lub siab - laser npav tshuab zoo yog qhov peev txheej tseem ceeb.
