Laser Engraving hloov cov khoom raw rau hauv precision kos duab, tab sis nws qhov muag tsis pom kev zoo lub qhov muag thiab tawv nqaij muaj phom sij. Tsis zoo li cov neeg siv hlau uas muaj cov khoom siv hauv tawb, engraving feem ntau yuav qhib - beads uas cuam tshuam los yog beape beaps tuaj yeem tawm tsam cov haujlwm. Cov lus qhia no kaum lub wavelength, fais fab pib, thov kev pheej hmoo, thiab kev paub tseeb kev tiv thaiv.
I. Laser engraving wavelengths: lub spectrum ntawm kev pheej hmoo

B. Daim tawv nqaij raug mob
High - Heart} Lub Hwj Chem IT / UV {{}} degree: 100mw / Cm² Rau 10s).
C. Cov xwm txheej thib ob
Ozone Ntau Lawm (UV lasers): Respiratory irritation at >0.1 ppm.
Fume inhalation: Toxic aerosols los ntawm vaporized plastics / Cov Hlau.
IV.Cov Khoom Siv Kev Nyab Xeeb Laser: Koj cov ntaub thaiv tiv thaiv hluav taws xob
1. Cov tsom iav tiv thaiv: Tsis - kev tiv thaiv kev tiv thaiv
Wavelength -}} Tshwj Xeeb Lim:
Coos Laser tsom iav: Thaiv 9.6-10.6μm (om ntau dua lossis sib npaug rau 4 @ 10.6μm).
Fiber laser tsom iav: Block 1064nm ±5nm (OD ≥6 for >50W cov tshuab).
UV Laser tsom iav: Thaiv 190-400nm + sab thaiv (xaiv ntau dua lossis sib npaug rau 4 @ 355NM).
Qhov ntsuas tseem ceeb:

VLT (pom pom lub teeb kis): Ntau dua lossis sib npaug rau 30% rau kev ua haujlwm kom ntxaws (piv txwv li, cov iav ci ntsa iab).
Ntawv muaj: EN207 (European Feem / Hluav Taws Xob Ntsuas)|Ansi Z87.1 (peb tus qauv).
2. Engineering tswj
Laser Kab Hlau & Barriers: Polyester / PVC FABRICS (OD 4+} rau 1064nm / 10.6μm).
FUME EXTRACTORS: HEPA + ua kom ua haujlwm rau cov power / filtration (tseem ceeb rau UV cov txheej txheem).
Interlock systems: Txiav txim txiav tawm ntawm lub zog thaum cov chaw qhib.
3. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
Ntsej muag shields: Polycarbonate Panels (Od2 @ 1064NM) + caj dab tiv thaiv.
Kev Tiv Thaiv Khaub Ncaws: Nplaim -} Resistant lab lub tsho loj (NFPA 70E rated).
V. XaivKev Nyab Xeeb Khoom: Ib qib 5-theem
Txheeb xyuas laser specifications

Xaus: Kev Nyab Xeeb raws li kev coj noj coj ua
Laser engraving unleahes muaj tswv yim tab sis xav tau kev tiv thaiv tsis muaj kev tiv thaiv. Tseem ceeb takaways:
⚠️ Wavelength dictite eyewear- co₂ ≠ Fiber ≠ UV kev tiv thaiv.
⚠️ OD & Ntawv Pov Thawj Tseg Tseg Tseg- Tsis kam lees txais "nyiaj txiag" Goggles.
⚠️ Reflections reflets yog cov neeg tua neeg- Sib txuas ua ke eyewear nrog kev thaiv / fume tswj.
Txoj Cai Kawg: Yog tias koj tsom iav kev nyab xeeb raug nqi tsawg dua li koj cov ntaub ntawv engraving, koj pheej hmoo dig muag. Kev nqis peev hauv kev tiv thaiv kev muaj ntawv pov thawj - rhuav cov hlwb tsis tsim dua.
