The greater the density of plywood, the better the quality. It is generally larger than the wood of the same species. The greater the unit pressure at the time of gluing, the greater the density of the plywood. Because wood is prone to plastic deformation at high temperatures, hot-press bonding has a greater compression rate than cold-press glue. Because plywood is made of crisscrossed veneers, its thermal conductivity is lower than that of wood of the same species.
Plywood is made up of thin pieces of wood, such as plywood, plywood, etc. Occasionally, there are odd numbers. According to the combination of different laminates, the thickness of plywood also varies. Generally, there are several specifications such as 3%, 5, 9, 9, 12, 15, and 18%. There are other thicknesses.
