红外与紫外激光打标机对复合材料激光打标性能的影响
Effect of Infrared and Ultraviolet Laser Marking Machines on Laser Marking Performance of Composites
采用最高功率为30 W的红外激光打标机与额定功率为1 200 W的紫外激光打标机,对滑石粉改性阻燃聚丙烯(PP)料、阻燃聚碳酸酯(PC)料、玻纤增强阻燃聚酰胺(PA)料进行打标测试,研究不同的激光打标设备,不同的打标工艺对材料打标效果的影响与差异。结果表明:紫外激光打标机的打标效果整体上优于红外激光打标机,标记效果PC>PP>PA。对于常用的PP、PC材料,采用红外激光打标设备进行打标更具性价比;而对于耐热性好的玻纤增强阻燃PA材料,采用紫外激光打标机打标更为合适。
Test the lasering marking performance on talc-modified flame-retardant polypropylene (PP) material, flame-retardant polycarbonate (PC) material, and glass fiber reinforced flame-retardant polyamide (PA) material by using an infrared laser marking machine with a maximum power of 30 W and an ultraviolet laser marking machine with a rated power of 1 200 W. The influence and difference of different laser marking equipment and different marking processes on the marking effect of materials are studied. The results show that the lasering effect of the ultraviolet lasering marking machine is better than that of the infrared lasering marking machine as a whole, and the lasering effect is PC>PP>PA. For commonly used PP and PC materials, it is more cost-effective to use infrared laser marking machine for lasering, while for glass fiber reinforced flame-retardant PA materials with good heat resistance, ultraviolet lasering marking machine is more appropriate.
