| 摘要 |
A lignocellulose substrate is coated with a powder. Laser radiation is used to fuse and optionally cure the powder to form a coating. Preferably the excess powder is removed. The powder is preferably a resin, especially an epoxy polyester resin. The substrate is preferably paper, cardboard, wood, particle board, oriented strand board or fibreboard. The preferably infrared (IR) laser is focused, so as to produce a design, especially on furniture. The method can be used to produce a Braille sign. |
