Features of ash, advantages and disadvantages of ash

Ash veneer is divided into two kinds: straight-grained ash and large-flowered ash. Straight-grained salix, that is, the lines of ash, are arranged vertically in rows, and the lines we usually see are like water ripples, with a sense of flow. The lines of ash are complex, and the color is yellow and black.

Sturdy, durable... Got it?

Advantages of ashwagandha:

1. Processing performance: ash has good processing performance, can be nailed, easy to process, tough, and well fixed with screws and glue.

2. The wood section of ash is very smooth, the color difference is small, the corrosion resistance, the water resistance is good, the coloring performance is good, the paint and sticky performance are also very good, and the surface effect can be taken through dyeing and polishing with good decorative properties.

3. Ash has a tough material, beautiful texture, and excellent overall strength performance, good seismic resistance and steam bending strength, which is a good material for making furniture.

4. Durability: Heartwood has moderate penetration resistance to anticorrosive treatment agents, white wood (sapwood) has penetration, and ashwagandha is very suitable for dry climates, its aging is very slight, and the heartwood changes little.

Disadvantages of ash:

1. Ash has no heartwood anti-corrosion ability, and white wood (sapwood) is susceptible to being eaten by powder beetles and common furniture beetles, which is not easy to dry and easy to warp.

2. Ash solid wood furniture, deformation Hongyou is larger, made of all real Zheng wood, mostly spliced with small wooden blocks (easy to deform and cause furniture damage), large pieces of wood shrinkage and deformation, not suitable; Some ash furniture is basically the main frame ash solid wood, and a large area is pasted with ash solid wood veneer, which is because of the large deformation and shrinkage of ash.

The advantages of ashiva are: 1. It has good wear resistance and moisture resistance; 2. The cutting surface is particularly smooth, and the paint and adhesive properties are also relatively good; 3. The material of ashwagandha is particularly tough, the texture is also very clear, and there is a beautiful luster; 4. Fraxinus mandshurica has good processability and has the ability to resist earthquakes. Cons:

1. It does not have the ability to resist corrosion, and is easily damaged by powder beetles and common furniture beetles; 2. It is prone to decay, deterioration, warping and deformation.

Fraxinus mandshurica is a large deciduous tree, and its walnut and yellow pineapple are known as the precious "three hard and broad tree species" in Northeast China.

Fraxinus mandshurica is a widely used and excellent timber tree species, which enjoys a high reputation in the international market, with a high rate of 4 to 5 times higher than that of conifer species. The trunk is straight, the material is tough and dense, elastic, the texture is straight, the planing surface is smooth and the mold is modified, the gluing and painting performance is good, and it has good decorative properties, which can be widely used in architecture, aircraft, shipbuilding, instruments, sports equipment, furniture, etc.

Fraxinus mandshurica is round and broad, tall and straight, with strong adaptability, cold resistance, drought resistance, smoke and dust resistance and pest and disease ability, is an excellent greening and ornamental tree species. At the same time, it can be combined with many coniferous and broad-leaved tree species to form a mixed forest ecosystem with a composite structure, which is of great significance and effect on improving the water conservation, soil and water conservation, and preventing environmental deterioration of the whole stand.
