In today's industrial manufacturing, laser is used more and more widely, such as laser welding,
cutting, marking, engraving, cladding, cleaning, etc., but people don`t pay more attention to
laser smoke harm in the process of laser machining.
Below we list the different laser processing technology in some of the by-products.
Hope the broad masses of laser equipment operators and senior management,
laser equipment manufacturers can cause more enough attention and take
effective, protective measures or take some suggestions.
1, Metal processiong
Produce heavy metal vapor in the processing of metal. The vapor can
damage the body's organs and tissues. From the point of medical
observation points, At least the following metals and their compounds:
A) Affective element:
Mn, Cr, Ni, Co, Al, Zn, Cu, Be, Pb, Sb
B) Can cause the following reflect:
1) Poisoning(（Cr+6, Mn）
2) Irritability（Zn, Cu）
2, Plastic cutting
May produce all sorts of potentially dangerous substances when cutting the plastic
. Aliphatic hydrocarbons at low temperature, while at high temperature can make
the aromatic hydrocarbon (such as benzene, PAH) and more halogen hydrocarbon
classes (such as his second oxygen, furan) increased. Some of the material may
produce cyanide,Isocyanate (PU), acrylic acid(PMMA), ROOH(PVC).
Can cause the following reflect:
1) Poisoning Cyanide, CO and benzene derivatives
2) Allergic source/irritants: isocyanate, acrylate;
3) Respiratory stimulation: toluene, acrolein, amine;
4) Cancer: benzene, some pahs materials.
3, Ceramic processing
3 oxidation 2 aluminium Al2O3, magnesium Mg, Si Ca calcium and silicon oxide;
Beryllium oxide BeO (poisonous)
4, The silicon wafer processing
Floating in the Si silicon and silicon oxide particles in the air
(may be sucked into the lung, can cause silicosis)
5, Paper cutting and wood cutting
General byproduct of cellulose, esters, acids, ethanol, benzene, etc.
