How to choose a good product can be through the following points: Looking at the flatness, look at the long (2440) side at a 45-degree angle where the light is slightly dark. If there is unevenness, see if the three splicing seams on the surface are obvious. Look at the surface for dried flowers and wet flowers. If the surface of the plate has bright spots like crystals or charring, such as children's urine spots, these are dry and wet flowers. All these reflect the degree of mastery of the factory process and one of the important issues in the quality of the sheet. The degree of sheet deformation also reflects the manufacturer's process capability. In general, it is normal for the plate to be slightly deformed at the top two of each package before it is finished. After being made into a wardrobe or a finished product (not including a large-area swing door), there is a problem with the quality of the deformation. Plate cracking is definitely a quality issue without any reason. The environmental protection of the board will be caused by the environmental protection degree of dry and wet flowers and plastics, but the carpenters will have a pungent taste when processing sawn timber. This is the taste of the wood itself, not environmentally friendly.
