Fir wood piles are currently widely used. As a kind of wood, it is affordable and cost-effective. For wood, the problem that needs to be solved is drying. In order to ensure the actual effect of wood application, this step must be paid attention to. Today, small We have compiled the content of factors affecting the drying of fir piles for your reference.

1. Green plants and their characteristics

The types of fir wood piles have different structures, such as the size and total number of holes. Generally, the smaller the diameter of the micropore plate on the porous film, the slower the drying speed. The higher the relative density of the same green plant, the slower the drying speed.

2,Thickness

The key to the traditional drying process is to transfer heat and mass along the thin-walled surface. As the thickness increases, the distance between heat conduction and convection heat transfer is lengthened, the friction resistance naturally expands, and the relative drying speed decreases.

3. Moisture content

The lower the moisture content, the slower the drying speed.

4. Grain orientation

Wood radiation is conducive to moisture transmission, and the moisture conductivity of wood in the axial direction is 15% to 20% greater than in the chordwise direction. Therefore, chordwise laser-cut boards usually dry faster than axially laser-cut boards.

Let’s first popularize the morphological characteristics of fir. The crown of saplings is pointed, and the crown of large trees is conical. The bark is grey-brown, splits into long strips and falls off, and the inner bark is reddish; the branches are flat and nearly opposite or whorled. , usually in 2 rows, young branches green, smooth and hairless.

We also need to know its main value: the wood is yellowish white, sometimes the heartwood is reddish brown, soft, delicate, aromatic, straight texture, easy to process, specific gravity 0.38, strong corrosion resistance, no termite attack. Used in construction, bridges, shipbuilding , pillars, wooden piles, poles, furniture and raw materials for the wood fiber industry.
