Talking about the characteristics, characteristics and use of wood

Picking Asian trees; The common commercial materials mainly include broad-leaved Asian trees in Southeast Asia and Asian trees. Trees and distribution Medium to large arbor, the tree height is l 5-20m ; the height under the branch is about 18m (the broad- cut picking sub-wood ) ; the breast diameter is 50-60cm . Mainly produced in Southeast Asia, tropical Africa and the Americas are also distributed.

 

Wood characteristics: Wood is a loose hole material. The heartwood and sapwood are clearly distinguished; the color of the wood varies greatly; the heartwood is light reddish brown, golden brown, reddish brown to purple reddish brown (the broad-grained sub-wood fresh wood light golden brown, turned brown or reddish brown by large-scale ) ; White, light yellow or light brown, the growth wheel is not obvious. The wood has a strong luster; no special smell or taste. The texture is staggered, the structure is slightly thin to slightly thicker, even to slightly uniform; the broad-skinned sub-wood texture is staggered or wavy, thin to slightly. Slightly uniform. The cut surface often has a strip pattern; the string cut surface often has a " v " shape pattern.

 

Wood properties: dry shrinkage, heavy wood, medium to high strength. Wood is resistant to corrosion or slightly resistant to corrosion; heartwood preservatives are easy to infuse. Drying should be slow, otherwise cracking will occur. Difficult to process, because wood not only looks like hard horny, but also heavy, textured staggered; rotary cutting and adhesive is quite good.

 

Wood use: heavy wood, high strength and impact toughness, beautiful strip pattern, suitable for bearing and ordinary floor; bridge, pier, pile, sleeper; ship, deck, mast, agricultural equipment; press, hard wood Accessories, tool handles and decorative veneers.

Lsr Injection Mould, is also called Liquid Silicone Rubber  Injection Moulding, LSR Injection Mold & LIM, which can produce liquid silicone rubber parts or products by injection molded machines, not by traditional silicone rubber compression machines using traditional production method, but by liquid silicon rubber injection mould production, which is safer, more precise & environmentally friendly & transparent, using less manpower, and having high production efficiency compared with rubber compression mold.
