What are the characteristics of several kinds of wood commonly used in sauna boards?

Fraxinus mandshurica: Its tree is slightly hard, its texture is straight, its structure is rough, its pattern is beautiful, its corrosion resistance is good, its water resistance is good, it is easy to process but not easy to dry, its toughness is high, its bonding, painting and coloring properties are good, and it has good decoration. It is widely used in furniture and interior decoration at present. Poplar: Wood commonly used in northern China is soft, stable and cheap. In ancient furniture, it is often used as the accessory of elm furniture and the fetal bone of lacquer furniture. This is the so-called poplar, also known as "Populus simonii", which often has a piece of luster, so it is also called "satin poplar", not the kind of Su Yang, Populus euphratica and Populus euphratica introduced in the middle of this century. Poplar is often very coquettish, lighter and softer than birch. On the other hand, birch has a slight fragrance and often has very fine brown-black water stains. This is the difference between the two. Cinnamomum camphora: It is found in all southern provinces of China, but there are more in Taiwan Province and Fujian. The tree diameter is larger, the wood width is wider, the pattern is beautiful, especially it has a strong fragrance, which can drive away insects.

China's camphor wood boxes are well-known at home and abroad, including suitcases, sleeping boxes (suitcases), top boxes and cabinets. Only tables and chairs are mostly in Beijing. In the old wood industry, camphor wood is divided into several types according to its shape, such as camphor, camphor tree, camphor tree, camphor tree, camphor tree, camphor tree and so on. Nanmu: It is a kind of high-grade wood. Its color is light orange yellow and slightly gray, its texture is elegant and quiet, its texture is moist and soft, it does not shrink, and it has a faint fragrance when it rains. All the southern provinces have production, but Sichuan is the best. In the Ming Dynasty, it was widely used by the imperial court. At present, the Forbidden City in Beijing and the excellent ancient buildings in Beijing are mostly built of nanmu. Nanmu is not rotten and fragrant. The Royal Library, with its golden painted throne, is decorated mostly with nanmu. Such as Wenyuan Pavilion, Leshou Hall, Hall of Supreme Harmony, Changling and other important buildings have nanmu decoration and furniture, which are often used with rosewood. It's a pity that many people don't understand it now, and often regard it as a sacred object. They think that the quality is not strong or heavy, and the color is not dark or bright, so they abandon it. The insiders' comments on its texture are as follows: Jin Sinan, Minnan, Minnan and Gentiana. In addition, in Shanxi and other places, hardwoods such as redwood and yellow pear are often called "Nanmu", the original meaning should be wood from the south. At first glance, it is easy to be confused with this "Nanmu".
