ついていた。2. Description of the Related Art Generally, as a plywood for a floor base plate or the like, an odd number of South Sea wood or softwood veneer is often used, and a plywood laminated such that the fiber directions thereof are orthogonal to each other is often used.
Veneer has large expansion and contraction due to difference in cold heat or humidity and low surface hardness, so it satisfies the performance required for flooring such as resistance to cracking, daily impact resistance, and dent scratch resistance by chair casters. It cannot be said that they are doing it. In order to solve these problems, existing products are those made by adhering MDF (Medium Density Fiberboard), which is a medium density fiberboard, to the surface of South Sea floor wood or softwood plywood under cold pressure. There is, however, the fact that it is attached later and M is relatively expensive
Since the DF is used, warpage occurs and the cost is high.
