Ozone
By using titanium-doped discharge tubes, UV radiation is absorbed
during high-frequency discharge, meaning ozone will not
accumulate outside of the discharge tube.
Polyethylene-coated (PE) tubes
Aliphatic and olefin compounds are released mainly while laser-
cutting polyethylene coated tubes:
•
N-heptane, 1-heptene, heptadiene.
•
N-octane, 1-octene, octadiene.
•
N-nonane, 1-nonene, nonadiene.
•
N-decane, 1-decene, decadiene.
•
N-undecane, 1-undecene, undecadiene.
•
Further n-alcane, 1-alcanes, diene pairs.
•
Toluene
•
Ethyl benzene.
•
L-limonene
•
N-butyl benzene sulfonamide.
Measurements of exhaust air by means of a total hydrocarbon
analyzer (FID) revealed concentration values ranging between
2 and 10 ppm, measured as methane. Hence, when laser-cutting
PE-coated sheets, it is not expected that the limit values will be
exceeded by the organic particles in the exhaust air. Strong-
smelling scattered exhaust air particles even at very low con-
centrations (ppb range) can cause minor smell irritations.
