Teak is a tropical tree that requires a higher temperature. Vertical distribution more common in the elevation of 700-800 meters below the low hills and plains. Teak wood hi tree species, the average annual temperature of 20 ℃ -27 ℃, absolute low temperature 2 ℃, the annual rainfall of 1100-3800 mm, dry and wet season significantly. Strong positive species, can grow in the sand shale, granite developed into red soil and red soil, hi deep, moist, fertile, well drained soil. Can be in the low temperature frost (-1 ℃ -2 ℃), the root is shallow, large canopy, vulnerable to wind damage, shelter to promote the cultivation. Teak growing fast, strong budding, cutting can be sprouted after the update. Trees up to 50 meters, 2.5 meters at breast height. Trunk straight up. Twigs four prism. Leaves simple, opposite pairs, leaves large, obovate, broadly elliptic or rounded. Flower arrangement of large panicles terminal or axillary, calyx bell-shaped, 5 ~ 6 short crack, the results of the expansion, ovoid or pot shape; fruit spherical, dense rusty hair, hidden in the persistent membranous calyx.
Teak wood nature: teak luster, to Myanmar for the best, teak oil bright, material color uniform, texture straight. Teak structure of crude fiber, medium weight, dry shrinkage coefficient is very small, dry shrinkage from the raw material to the air to dry 2.2%, the string to 4.0%, is the smallest deformation coefficient in wood, good bending resistance, Abrasion resistance, air dry density of 0.65g / cm3 (dry material weight of about 650 kg / m3). In the sun and rain, wet and wet changes in the case of large cracks do not crack; water resistance, fire resistance; resistance to termites and different seabirds eating, very decay resistance. Good drying performance, adhesive, paint, waxing performance is good, because the silicon easy blunt knife, so when cutting more difficult. Holding nail good, comprehensive performance is good, it is recognized as the world's valuable species.
Verbenaceae (Verbenaceae) distributed in some countries in Southeast Asia such as: (Myanmar, Indonesia, Laos, Vietnam, Thailand, India) China in the vicinity of the border there are some, of which Thailand, Myanmar is the most famous, the wood species Mainly imported from Myanmar.
Form: teak is a tropical tall broadleaf trees, up to 39-45 meters, the diameter of about 1.5 meters. Bark brown or gray, branches quadrangular, stellate hairy. Leaves opposite, large, ovate or elliptic, abaxially densely grayish-like stellate hairs. Panicles large, autumn blooming, flowers white, aromatic. The world's precious timber species; hand the teak leaves twisted, with blood red coloring coloring fingers, and sometimes difficult to wash, so call it rouge tree or blood tree. Suitable growth temperature: Absolute maximum temperature of 43-48 ° C Absolute minimum temperature at 2 ° C
Nature: teak with golden luster, teak oil bright, material color uniform, texture straight. Bark thick 0.5 ~ 1.0cm, soft, easy to peel. Skin grayish brown; easy small flake peeling. Endothelial reddish-brown; brittle fiber developed, layer-like arrangement. Its cross-section of the heart of the difference between the obvious. Heart material golden brown, with oil sexy. Sapwood yellow and white, width of 1.0cm. The growth wheel is obvious and uneven. Teak structure of crude fiber, medium weight, dry shrinkage coefficient is very small, dry shrinkage from the raw material to the air to dry 2.2%, the string to 4.0%, is the smallest deformation coefficient in wood, good bending resistance, Wear, air dry density of 0.58 ~ 0.67g / cm3. In the sun and rain dries wet and wet changes in the case of large warp cracking is not easy; water resistance, fire resistance; to resist termites and different seabirds of the sea insects, very decay resistance. Good drying performance, adhesive, paint, waxing performance, because of silicon easy blunt knife, this time must wear a mask to wear, to prevent the silicon-containing powder into the lungs lead to silicosis, processing more difficult to cut. Holding nail good, comprehensive performance is good, it is recognized as the world's valuable species.
Uses: teak is the best material for making high-grade furniture, flooring, interior and exterior decoration. Applicable to shipbuilding, open air construction, bridges, etc., especially suitable for manufacturing ship deck. A variety of chemical substances have a strong corrosion resistance, it should be used for chemical industry with wood products. Especially in the floor, corrosion-resistant, wear-resistant, shiny bright as the new, beautiful patterns, elegant tattoo color, good stability, deformation is small, in fact, the best in the floor. The current market of mahogany furniture, one of which is made of teak. As the precious teak rare, leaves and large, excellent material, the value of large, at this stage in Guangdong, Fujian Province, two provinces have been used for street trees, green plot, garden embellishment and green side by side. It even becomes a hedge commodity
Features: medium weight, not easy to deformation, waterproof, very resistant to corrosion. In European countries, teak is used to make the most luxurious yacht, TITANIC (Titanic) deck is decorated with teak, it looks still very good today; a hundred years of history of the cathedral and ancient buildings are also teak Do the floor. Teak is precious, from growth to finished material for at least 50 years, in the natural environment, the best place of origin per acre is only 1 to 5 trees. It also contains a very heavy oil, this oil to keep it unchanged, and with a special flavor, can drive snakes, insects, rats, ants. Even more amazing is that its surface color is through the photosynthesis oxidation made of golden yellow, the color will be more beautiful with the extension of time. Known as the "king of million wood" in Myanmar called "national treasure".
