Large core board selection

The surface of the large core board should be flat, without warping, deformation, no blistering or dent; the core strips are evenly arranged, the gap is small, and the core strip has no decay, breakage, wormholes, thrift and so on. Some blockboards cut corners, and the gap between the solid wood strips is large. If nails are nailed in the gap, there is basically no nail holding force. Consumers can look at the sun when they choose, and the gap between the solid wood strips will be white. If the glue strength of the blockboard is not good, it will have a "吱吱" opening sound when it is self-financing. If the large core board emits a fragrant wood smell, it means that the formaldehyde emission is less; if the smell is pungent, it means that the formaldehyde is released more.

The quality of the large core board varies greatly, so check it carefully when purchasing. First of all, see if the core material is dense, whether there are obvious seams and decaying wood strips, there may be eggs in the decaying wood strips, and insects will occur in the future; then see if there is any glue or greasy putty around. It is to compensate for cracks or voids inside; then use a sharp-nosed instrument to strike the surface of the board to see if the sound is very different. If the sound changes, there is a hole inside the board. These phenomena will weaken the overall bearing capacity of the board, and the uneven long-term stress will cause the sheet structure to be distorted and deformed, which will affect the appearance and use effect.
