ilayer plywood?
It is formed by hot pressing of three or more layers of veneer or thin board wood glue. Splints are generally divided into six specifications of 3 cm, 5 cm, 9 cm, 12 cm, 15 cm and 18 cm (1 cm is 1mm). The environmental protection level reaches E1, and it is currently the most commonly used material for handmade furniture. It is also the most cost-effective material on the market. Compared with ordinary market plywood, multi-layer plywood has small deformation, high strength, good internal quality (small holes after sawing, no delamination), good flatness, and can produce 5–40mm different thicknesses, multi-layer The plywood is made of multi-layer plywood arranged in a crisscross pattern as the base material, and the surface is made of high-quality solid wood veneer or technical wood as the fabric, and is produced through several processes such as cold pressing, hot pressing, sanding, and health preservation. Because the multilayer plywood has the characteristics of not easy to deform and the excellent performance of good indoor temperature and humidity adjustment, the surface layer of solid wood veneer material has the natural and real wood texture and feel, so the selectivity is stronger.

Four: How to buy multi-layer boards

There are positive and negative points for the multi-layer board. You can check the appearance when purchasing. Try to choose a board with clearer wood grain, and the front side is generally smooth, the hand feels better, and it is not easy to be damaged.
2. Look at the patchwork
In the production process of multi-layer boards, veneers with different textures are collaged and processed together. Therefore, when purchasing, check whether the gaps are tight and whether there is unevenness.
3. Listen to the sound
Knock the multi-layer board with your hand to determine whether there is a problem with the material. If the sound is clear and crisp, it means that the board is of good quality. On the contrary, if the sound is dull, the quality is poor
