一、原理
激光打标粉主要功能是吸收激光能量,将激光束转换成热能,对塑料产生热作用、碳化作用、蒸发作用及助剂自身变色产生的化学反应,从而在产品表面形成的标记图案;
激光打标的“发色”原理
a.炭化法
经激光照射后,助剂发热以致周边树脂烧焦炭化,使工件留下黑色的标记,而这种方法一般合用于浅色的基材。一般常见于”白打黑”的技术中.
b.发泡法
助剂发热以达到树脂的降解程度而产生出热气而使基材形成大量细小气泡,这可做出浅色以至白色标刻效果,这合用于深颜色及黑色的基材。一般常见于”黑打白”的技术中.
c.烧蚀法
以高能激光把树脂完全气化使基材造成凹入的纹理。一般用于雷射直接成型的技术(LDS)中(Laser Direct Structuring)
c.助剂自身变色
经激光激发后,助剂发生化学变化,使得助剂颜色变深, 这方法合用于颜色浅的基材。一般用于于”白打黑”的技术中.
应用范围:
绝大多数通用塑料以及部分工程塑料,如PP,PE,PVC,PBT,PET,PA,ABS,POM,PS,PC,TUP,PUS,EVA等,也可用于塑料合金如;PC/ABS等材料,激光打标的字迹清晰光亮,可标记出黑色,白色字迹。
添加量:
千分之三—五左右,具体情况视塑料的透明度而定标记颜色为黑、白、灰。公司可根据厂家提供的不同塑料原料,给出与之相配的混合建议配方,以达到塑料上激光打标时的效果。
适用激光打标机光源类型以及波长范围:CO2激光,光线激光,Nd固体激光,红外激光,波长范围:308-1064nm。
可标识于:
本色塑料、白色塑料、有色塑料、黑色塑料激光印标已经成功商业化的应用包括牲畜耳标,灯开关盖,化妆品包装材料,汽车内部按钮和门把手、仪表板,商业机器用的ABS键盘、HDPE、即、PET和PVC刚性容器和容器盖,尼龙和PBT汽车和非汽车用电器连接件,发动机罩元件如保险盒和气帽,防伪标签,集装箱锁扣,文具,家电外壳等。塑料的激光焊接已经在继电器领域成功应用。
