2. recognize the difference between veneer veneer and natural wood veneer veneer mica board
The texture of the mica board of the former is basically straight, and the texture pattern is regular; the mica board of the latter is a natural wood pattern, and the natural variability of the texture pattern is relatively large and irregular.
3. Appearance inspection of mica board
The appearance of the mica board should have a good aesthetic feeling, the material should be meticulous and uniform, the color and luster should be clear, and the wood grain should be beautiful.
4.the structure of the glue layer of the mica board is stable, and there is no phenomenon of glue opening
It should be noted that there should be no bulging or delamination between the veneer on the surface of the mica board and the substrate, and between the inner layers of the substrate.
