What are the characteristics of plywood density and thickness plywood?

The plywood that we often use for decoration is also called plywood. The single-layer plywood is a common plywood type such as plywood and plywood. This type of wood-based board can effectively increase the efficiency of wood use, and the price is relatively low, so it is loved by many consumers, then we specifically understand the density and thickness of plywood, and plywood specific characteristics of the relevant content.

Plywood density and thickness

One: density

1, this kind of plywood production method is the use of multi-layer thin veneer, they are stacked together for adhesive hot pressing. The higher the density in general, the better the quality, and the density of the plywood will be greater than that of the wood of the same kind of material, the greater the pressure exerted during the pressing. The greater the density of the plywood it produces, the higher the deformation of the wood, so it must be fast during hot pressing.

2. The greater the unit pressure at the time of gluing, the greater the density of the plywood. Because wood is easily deformed under high temperature, the compression ratio of hot-pressing is larger than that of cold-pressing. The plywood is made up of crisscrossed veneers. Its thermal conductivity is lower than that of timber of the same species. The outermost veneer of plywood is called the surface plate, the front surface plate is called the panel, the negative surface plate is called the backplane, the inner layer of the veneer is called the core plate or medium. board.

Second: thickness

The decoration materials are all known to be laminated using a plurality of thin wood planks, and its thickness also depends on how many wood chips are used. For different combinations of laminates, the thickness of the plywood is also different. Generally, there are several specifications such as 3 PCT board, 5 PCT board, 9 PCT board, 12 PCT board, 15 PCT board, 18 PCT board, etc. Of course, there are other thicknesses depending on the special circumstances. Because plywood is relatively strong and has good stability, many users will purchase this kind of wood, but plywood uses more glue, so we must do a clean job on the edge of the gap.

What are the characteristics of plywood?

Plywood has a balanced high strength and does not shrink, expand, or deform. Plywood is not susceptible to cracking, so you don't have to worry about cracking when nailing or screwing. Since plywood is a man-made board, it has a wide range of sizes and can be made to different sizes according to different needs. The plywood surface is easy to form, and the curved surface design in modern buildings can be done using plywood. In addition, the plywood is light in weight and easy to produce, move, and install.
