The side of the big core board generally has the manufacturer's trademark, production address, date, and anti-counterfeit labels. The first thing to check is whether the brand, specification, model, etc. are consistent with those specified in the contract. The excessive formaldehyde content in the Daxin board has great harm to the human body, so we should also look at the Daxin board's quality inspection report or other quality assurance documents provided by the manufacturer. See if the formaldehyde content meets the E1 environmental requirements. Finally, the supervisor suggested that we look at whether the surface is dry, clean, how dense the core material is, and whether there are any problems such as deformation, rot, pods, or wormholes. The regulations in the industry stipulate that one side of the big core board must be a whole piece of wood board, and the other side can only allow one patchwork.
