The following points should be mastered when selecting:
(1) plywood has the difference between positive and negative sides. When selecting, plywood should have clear wood grain, bright and smooth front, not rough, but flat.
(2) Plywood shall not be damaged, damaged, worm, nail holes, dead joints, burrs, grooves and other defects.
(3) plywood has no degumming phenomenon;
(4) Some plywood is made of two kinds of veneer stickers with different grain, so when choosing plywood, attention should be paid to that the joints of plywood should be tight and there is no unevenness. Especially, do not have two different lines on a piece of plywood, otherwise it will hinder rational use, cause waste and affect the beauty of furniture.
(5) When selecting plywood, attention should be paid to selecting plywood that does not spread glue. With a wooden stick of about 50cm, lift the plywood and gently tap each part, and the sound is symmetrical and crisp, basically equal to the inner board; If "shell-and-shell" sounds dumb, it may be due to internal quality problems caused by degumming or bubbling. This kind of board can only be used as lining board or top and bottom board, not as fabric.
(6) When selecting plywood, pay attention to the coordination between wood color and furniture paint color.
