Beech
The aliases are beech, mahjong, limousine, white half-tree, miscellaneous tree, short chestnut tree, long-handed beech.
Distributed in China, Zhejiang, Anhui, Jiangxi, Sichuan, Guizhou, Yunnan, Hunan, Hubei, Guangdong, Guangxi and other provinces. In Yunnan, this tree species is the main tree species in natural broad-leaved trees with an altitude of 1500-1800m. In the area of ​​1000-2100m above sea level in Hubei, it is often mixed with parasitoid species or pure forest.
Standing trees, about 25m high, diameter of about 60cm, trunk straight, bark gray or gray, thin and smooth.
Material heartwood sapwood difference is not obvious. The wood is light reddish brown to reddish-brown, shiny, with no special odors and taste. The wood texture is straight or slanted, uniform in structure, and heavy and hard. The average air-dry density of wood is 0.792g/cm3. The average values ​​of the radial, chordwise, and volumetric shrinkage coefficients are 0.187%, 0.417%, and 0.627%, respectively. The average diameter, chord surface, end face, and hardness are 68.5 MPa, respectively. , 66.7MPa, 72.8MPa.
Dry wood dries slowly, shrinks and shrinks, and is prone to cracking, splitting, and warping when dried.
The strength of the wood is moderate, and the average value of the ultimate strength of the straight edge is 48.9 MPa. Durable wood is weak or moderate in corrosion resistance.
Technological characteristics Wood cutting is easy. Silver-white patterns are available on the radial surface. The paint has good lightness and easy adhesion. Hold nails strong, but sometimes split.
Uses For musical instruments, instrument boxes, high-grade furniture, veneer veneers, plywood, flooring, wall panels, hallway handrails, sports equipment, ships, vehicles, stationery, workers and peasants handles, agricultural implements, barrels, toys, miscellaneous utensils, Wooden pillars, sleepers, pit wood, poles, paper, and charcoal are also good raw materials for fuel wood.
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
