The common materials and characteristics of table tennis floor are as follows: \x0d\ 1, Ayous (transliteration: Ayous or Yayus) \x0d\ also known as Abachi and Obeicher, produced in Gabon, Africa. This kind of wood is light and tough, and is widely used as the panel and core material of the floor by floor manufacturers. For example, Yinhe 992# is made of Ayous and carbon fiber. \x0d\2, Cedar (Yingui) wood \x0d\ has the characteristics of light weight, elasticity and toughness, and is widely used by Japanese flooring manufacturers to make veneers for panels, core boards and ball boards. The floor made of cypress is suitable for fast arc and fast arc playing, and this kind of wood has become less and less common. \x0d\3, Limba \x0d\ The Nordic hardwood (Limba) that European flooring manufacturers often say is actually produced in South America. Divided into soft wood and hardwood, the material is brittle, the fiber is long and resistant to moisture. Many European flooring manufacturers generally use this kind of wood as the panel of the ball board. \x0d\4. Koto (Koutou) \x0d\ is produced in Africa, Asia and other places, with brittle materials, long fibers and moisture resistance. Many Asian and European flooring manufacturers generally use this kind of board as the panel of the ball board, and its performance is close to that of Limba. \x0d\5。 Walnut \ x0d \ is produced in southwest China, Myanmar and other places. In North America, there is hickory, which is hard, dark brown and tough, and is often used as high-grade floor panels. \x0d\6, basswood \x0d\ The wood used in early floors in China was basswood. Basswood flooring has occupied a large proportion for a period of time (nearly 40 years) and has been in use ever since. Its disadvantage is its heavy weight, which is generally above 100g, and it is mainly suitable for straight plates. \x0d\7. Paulownia (paulownia tree) \x0d\ is mainly produced in Asia, with fast growth, light weight, soft quality and low strength. Generally used as the core material of the bottom plate, it has crisp sound quality and good resonance, and is suitable for manufacturing high, medium and low-grade bottom plates. \x0d\8。 Spruce \ x0d \ Spruce is a light, soft and medium-strength wood. The best wood is straight, dense, with even annual rings, and is often used horizontally in the subsurface layer of the floor, which is called strength wood; Floors made of this kind of wood are suitable for fast arc and fast arc playing, and this kind of wood is becoming more and more scarce, so logging has been banned in China. \x0d\9. Eucalyptus globulus (Lao 'an) \x0d\ The real Eucalyptus globulus is produced in the Philippines, which is the real difference from miscellaneous trees in Southeast Asia. Merlanti Point in Malaysia and Indonesia can also be called eucalyptus globulus. Eucalyptus is hard, with long fibers and elasticity. The wood is close to spruce and slightly cracked when it is dry.
