Many stores will give a label on the wooden doors and windows "high-grade imported wood." However, timber imports are not fake. Whether it is high or not is subject to research. For many people, wood is not particularly clear except for common ones. Although some wood is not common, it is often seen in life. It is widely used in the door and window market. Some of the high-end, atmospheric, and high-grade woods, although expensive and expensive, are not as good as the most common pines for doors and windows. Xiao Bian especially summed up several common imported woods for everyone, look at their characteristics, refuse to consume traps, and start by learning to look at wood.
Black Walnut (scientific name: Juglans regia, L)
Appearance Black walnut heartwood brown, sometimes with black or purple stripes. The color of black walnut varies depending on the area in which it grows. Therefore, the reason for the black walnut is not that the wood is black, but because the fruit shell is black, the wood is actually light gray brown to dark purple brown. Therefore, black walnut is often referred to as walnut. The nature of the black walnut wood varies greatly, forming a variety of different patterns, which are loved by people. The wood is heavy and hard, resistant to impact and friction; resistant to decay, easy to dry, less deformed; easy to construct, easy to glue. The wood is hard enough to make the engraving part of modern furniture, and its shrinkage rate is very small, so it can withstand the climate of change, and cracks occur innocent. Any coating method can be applied, and other woods are not as good as black walnut can absorb oily coating, which is another reason why it is used to make modern furniture. Use. Ideal for furniture and interior decoration. Apply traditionally painted black walnut wood, only need to wash with neutral soap and water, polish with wax to maintain the original appearance; for oily painters, apply boiled linseed oil twice a year.
Teak (scientific name: Tectona glandis, L)
Teak color from honey to brown, long and thick, the material is durable and durable, the heartwood is quite like a coffin, and the color is slightly thicker. The expansion shrinkage is at least one of all woods. It can resist the erosion of sea and land animals, and does not corrode iron. Because of the small shrinkage rate, it is not easy to leak water. Because teak has high corrosion resistance, it is not easy to be deformed in various climates, and it is easy to construct and many other advantages. Therefore, it is suitable for the manufacture of ship charters and for ship decks. It has become a high-class wood famous in the world. Scandinavian and Oriental furniture are mostly made of teak.
Blackwood (Chinese name M.fordiana (hensl) oliv
Evergreen trees, up to 25 meters high, 15 meters high under the branches, 80 cm in diameter, up to 140 cm. It is mainly produced in evergreen broad-leaved forest at an altitude of 800-1800 meters in northwestern Myanmar. It is more than 120 years old. Among the commonly used trade names in the Yunnan timber market are the names of black heart, black heart, and black heart. Because its finished products are similar to teak, it was named "Golden Silk Pomelo" in the timber market in Shanghai, Guangzhou and Beijing.
Wood material:
The wood has loose holes, the heartwood is golden yellow to grayish brown, and the difference is obvious from the sapwood. The sapwood is light yellow-white, the production wheel is slightly obvious, and the wheels are light-colored thin lines. The tube hole is slightly more, very small to slightly smaller, obvious under the magnifying glass; the size is the same, the distribution is quite uniform, scattered, and the invading body is not seen. The amount of thin-walled tissue on the axial surface is small, and the wheel-shaped shape is slightly seen under the naked eye. The number of wood rays is medium, very fine to slightly fine, visible under the magnifying glass, the tube hole is small, and the radial cut surface has extremely fine ray markings.
Wood properties:
The wood has strong luster, no special smell and taste, wood is resistant to corrosion and insects; the texture is straight, the structure is very fine and uniform. Medium hardness (air dry density 0.5kg/cm3), medium drying speed, dry shrinkage, no deformation, easy cutting, smooth cut surface, good gloss after painting, and the effect is close to teak.
The timber was the preferred material for the palace building during the Ming and Qing Dynasties. It is now used for high-quality furniture, suitable for plywood, interior decoration such as doors, windows, floors, arts and crafts, sculptures, etc.
Australian Red Dragonfly:
Wood material: oily, shiny, staggered texture; heavy weight, high strength; dry shrinkage (1mm), stable material. Easy processing, smooth surface; good adhesion, paint and nailing, corrosion resistance, dry. The air-dry density is 1.13g/cm3, which is much superior to the red-spotted scorpion in Southeast Asia. The color of the board is reddish and it is called the Australian rosewood.
Wood use: mahogany furniture, flooring, veneer, mouldings, stairs, interior decoration, crafts, sound, piano manufacturing, etc. Australian blue dragonfly and Tasmanian wood are hardwoods, but also like wood. The heartwood is grayish yellow, light brown, gradual from sapwood to heartwood, and the tube is also visible to the naked eye. The air-dry density is 0.65-0.8g/cm3, the texture is clear and the stability is good.
