Research on smoke and dust of laser etching reinforced polypropylene
The amount of smoke and dust generated by laser etching reinforced polypropylene was studied.The re-sults showed that the smoke and dust generated by laser etching reinforced polypropylene was mainly composed of spherical objects of PP and glass fiber powder.The carbon black is the main cause of smoke and dust produced by laser etching reinforced polypropylene.The glass fiber is the main source of smoke and dust produced by laser etch-ing reinforced polypropylene.The greater the shear strength experienced by reinforced polypropylene during the processing,the shorter the length of glass fibers retained in reinforced polypropylene,and the greater the amount of smoke and dust generated during laser etching.
