plastic. At lower temperature, aliphatic hydrocarbon will be produced; at higher temperature,
aromat ic hydrocarbon (e.g. benzene PAH) and polyhalo-polynuclear hydrocarbon (e.g.
dioxin, furan) will be increased. Some of these substances may possibly generate cyanide,
isocyanate (PU), acrylate (PMMA) and hydrogen chloride (PVC).
Medical influences include:
--------Toxic: Cyanide, CO, derivative of benzene
--------Allergy source/irritation: isocyanate, acrylate
--------Respiratory stimulating: formaldehyde, acrolein, amine;
--------Carcinogenesis: benzene, some PAH substances A1.6 Surface modification
Generally, there is no noticeable outgrowth, but sometimes heavy metal steam is generated.
A1.8 Paper and wood Marking
General fibrin outgrowth, ester, acid ethanol, benzene
Alarm
◆
During laser marking, the smoke generated may be very toxic. The smoke
is removed by upper exhaust blower system;
◆
Marking with abnormal blower system is prohibited.
Note
◆
Make frequent check on the ventilation system;
◆
Clean and maintenance the blowing system regularly;
◆
Foreign matter coming into duct of the blowing system is strictly prohibited;
◆
Ensure a good vent ilat ion and the exhaust gas expel from the working
room;
◆
Ensure a necessary disposal of the exhaust gas to sat isfy emission
requirements prescribed by the state and local government.
2.6.6 Risk of optical system
2.6.6.1 Routine operation
The optical system of the laser marking machine doesn’t need to be maintained with great
attention, however,
due to the great amount of dust generated by marking, the field lens should be cleaned
frequently.
