Chinese literary name: Eucalyptus Salix
Distribution: Southeast Asia
Usage: Suitable for rotary cutting veneer, plywood and furniture
Wood property: lustrous, texture interlaced; coarse structure
Large tree of Eucalyptus salicifolia, including Eucalyptus globosa, Eucalyptus pallidus and Eucalyptus yellowii. Wood properties of Eucalyptus salicifolia: Wood has luster, no special odor and taste, interlaced texture, coarse structure, uniform weight. Liuyu wood has good natural gas dry property, only slightly cracked, almost no degrading defects.
Eucalyptus willow: divided into (Eucalyptus alba) Eucalyptus yellow willow, Eucalyptus red willow two kinds.
Eucalyptus alba, evergreen tree, high and straight trunk, thick wood structure, straight or inclined texture staggered, easy to dry and process, and nailing, paint, gluing and other properties are good. Physical properties: soft material, easy to crack, medium strength and toughness, medium seismic performance, medium corrosion resistance, medium steam bending performance, used in building furniture, floor plywood, outdoor floor, cabinet and other widely used.
The wood texture of Eucalyptus globulus is similar to that of Eucalyptus globulus. Its diametral section is beautiful, but its drying and processing are difficult. Physical properties: Hard material, high strength and toughness, good seismic performance, moderate corrosion resistance and steam bending performance, used in high-end household, indoor flooring, cabinets and other widely used, can be used as a substitute for mahogany. Meanwhile, the sawdust of Eucalyptus salicina is mostly used in the culture medium of edible fungi such as Pleurotus eryngii.
Eucalyptus willowii warped and cracked slightly during drying. The wood of Eucalyptus Salix is hard, with brown eyes, long fibers, large elasticity and easy to deform.
Red Willow Eucalyptus. Macroscopic structure: porous materials. Pipe holes are obvious in the naked eye, few and slightly larger are mainly single-pipe holes, a few short-diameter multiple-pipe holes (2-3); some oblique; abundant intrusions. Axial parenchyma can be seen under a magnifying glass with enviromental and near-wing shape. Wood ray magnifier is visible, sparse, narrow to slightly wide. Axial gum duct is obvious under naked eyes, with white stringed bands of varying lengths.
Trees: Evergreen trees, as high as 60 m, DBH about 2.0 m, often with plate roots. There are about 70 species in this category. They are often divided into dark red and light red according to their colours.
Distribution: Distribution in Southeast Asia. Mainly imported from Indonesia and Malaysia, large quantities.
Cross section: The difference between heartwood and sapwood is slightly obvious, heartwood is reddish brown to brick red. The sapwood is yellow-white, 3-4 cm wide, and the growth ring is not obvious.
Bark: 1.0-2.0 cm thick, soft, easy stripping. The epidermis is dark reddish brown, with fine cracks, small flakes of exfoliation, and the endothelium is brown-red. The phloem fibers are well developed and easily separated into hemp filaments. The hemp filament endothelium is often remained on the surface of wood.
Wood properties: glossy, texture interlaced; coarse structure, medium to heavy weight; medium to high strength, dry shrinkage, easy processing, smooth surface, gluing, paint and nail performance, slightly anti-corrosion, slightly pleasant drying, slightly warping, air-dry density of 0.56-0.86g/cm3.
Usage: Suitable for rotary cutting veneer, plywood, furniture, mahogany, floor, interior decoration, general building, shipbuilding, etc.
Recognition points: The surface of wood is often residual linen filamentous endothelium, heartwood is red-brown to brick-red, pore infiltration is rich, the axial gum duct is obvious under the naked eye, and the white stringed band is different in length.
It is widely used in furniture, interior decoration, doors and windows, doors and window frames, wall panels, footboards, model materials, veneers, plywood, ship boards, pulp and papermaking, etc. Yellow, suitable for light structural materials, frames, partitions, furniture, low boards and palette, especially for high quality plywood. White, suitable for staircase handrails and pedals, baffles, light to medium-sized structural materials, frames, partitions, furniture, floors and plywood.
