最近,葡萄牙发明家采用一种激光扫描技术,可把人造彩色大理石制造得与天然彩色大理石一模一样,真假难辨。 其制造方法是:用激光束给大理石表层涂上永不褪色的人工色,而所能达到的最好效果是用移动的反光镜反射二氧化碳激光,这样染出的色彩会被大理石料吸收而呈现出与自然样品一样逼真的色彩。例如,他们把一块白色大理石放置于140 W的CO_2激光下,并加入翠 Recently, the Portuguese inventors used a laser scanning technology to make artificial colored marble exactly the same as natural colored marble. The method of manufacture is: using a laser beam to coat the marble surface with an artificial color that never fades, and the best effect that can be achieved is to use a moving mirror to reflect the carbon dioxide laser, so that the dyed color is absorbed by the marble material and presented The same color as natural samples. For example, they placed a piece of white marble under a 140 W CO 2 laser and added
