Choosing plywood, in addition to the appearance, the inherent quality is more important. Plywood has three, five and seven plywood. In general, it is better to make furniture with ash, eucalyptus and Liuan. The following points should be mastered when selecting.

(5) When selecting the panels, care should be taken to select the panels that does not disperse the glue. You can use a wooden stick of about 50cm to gently pry the plywood to the various parts. The sound is well-proportioned and crisp, basically waiting for the inner panel; if the "shell" is muted, it is probably due to degumming or bubbling. The inherent quality problems caused. This type of board can only be used as a lining plate or a top plate and cannot be used as a fabric.



(6) When selecting the panels, pay attention to the color of the wood and the color of the furniture paint. Generally, the ash and eucalyptus plywood paints are light yellow, and the ochre furniture can be used. However, the Liuan panels has a deep and shallow color, and there is no problem in the light color finishing. However, dark colors can only be made into twilight furniture, but not light yellow furniture, otherwise the furniture will be dark. Although the dark color can be washed with ammonia water to wash the light yellow furniture, but the effect is not satisfactory after treatment, the color of the furniture will still change color after several years of use.

(7) On the corner of the regular plywood board, there are generally grade marks for reference.The grades of domestic plywood are: (first class), (second class), (third class), (etc.).Imported plywood is represented by "AA", "BB", "CC", "CC" - 2, 3, 4, etc. If the board is marked with "B", "C", "D", it is a plywood from Romania. If there is no imprint, it is likely to be bubbling or degumming. Please pay attention to this when selecting.
