â— Wood name: Ai Li Gu Yi Su Mu
â— Place names: Ovengkol, Ovangkol (Gabon), Ehie, Bubinga, Anokye, Hyedua, Hyeduanini (Ghana), Amazakoue, Amazoue, Whimawe (CÃ´te d'Ivoire, Liberia), Palissandro (Equatorial Guinea), Black Hyedua (Ghana, Nigeria), Osun (Nigeria), Klsese, Ngula (Zaire, Congo), Daniela (Italy), Mozambique (USA).
â— Non-standard name: ebony, African teak.
â— Trees and distribution: large trees, up to 45m, diameter up to 2.5m; large roots; common small grooves in the material table. There are 15 species of this genus and 11 species of Africa, distributed in West Africa and Central Africa. This species is often imported from Cameroon, Gabon and Equatorial Guinea.
â— Bark: 1.0 to 1.5 cm thick, hard and not easy to peel off. The outer skin is smooth; grayish brown to light grayish yellow; easy to flake off. The endothelium is dark brown; the bast fiber is slightly developed.
â— Cross section: The difference between heart and sapwood is obvious. Heartwood is tan to chocolate, with black concentric stripes. The sapwood is yellowish white to grayish white and has a width of 5 to 9 cm. The growth wheel is slightly obvious.
â— Macro structure: loose hole material. Tube holes can be seen under the naked eye, slightly less, slightly larger; the main is a single tube hole, a few diameters of the complex tube hole (2 ~ 3); containing dark gum and beige deposits. Axial parenchyma is visible under the naked eye, developed, winged, poly-winged and rounded. Wood rays are visible under the naked eye, medium density and slightly wider.
â— Wood material: shiny; with a bad smell. The texture is slightly staggered; the structure is fine and uniform; the material is hard and heavy; the strength is high; the shrinkage is very large. Easy to process, suitable for veneer cutting; good adhesion and paint performance. Slightly resistant to corrosion. Slow drying and good performance. The air dry density is often greater than 0.8 g/cm3.
â— Wood use: Suitable for sliced â€‹â€‹veneer, plywood, high-grade furniture, wood lines, house construction, durable materials, flooring, kitchen facilities, chemical barrels, etc.
â— Identification points: the outer skin is smooth; gray brown to light gray yellow; easy to flaky off. The string cuts have beautiful black "mountain" stripes. The tube hole contains dark gum and beige deposits. The wood is hard.
Polycarbonate (referred PC) is a polymer molecular chain containing a carbonate group, an ester group according to the structure can be divided into aliphatic, aromatic, aliphatic - aromatic and other types. Which due to the aliphatic and aliphatic - aromatic polycarbonate lower mechanical properties, thereby limiting its application in engineering terms. Currently, only the aromatic polycarbonate obtained industrial production. Due to the special nature of the polycarbonate structure, it has now become the top five fastest growing engineering plastics in general engineering plastics.
PC chairs made of plastic material and they have the same advantage.
