Wood species introduction and timber purchase methods

So how do we specifically choose wood? First of all, you should first understand wood.

1, the type of wood

At present, the more commonly used tree species in home decoration are:

(1) Fraxinus mandshurica

The wood grain of ash is very prominent. The sapwood is yellowish-white, the inside is brown with yellowish color, the wood color after the sawing is slightly golden yellow, the hardness of the material is medium, the texture is smooth, the pattern is beautiful, the processing performance and Good paint performance, water resistance, abrasion resistance and small deformation, so it is an ideal surface material, suitable for a variety of different furniture.

(2) Birch and Beech

The birch has fine structure, high strength, good color, loose texture, easy processing, no obvious difference between the core and sapwood, and a beautiful pattern on the chord section. After drying, it is easy to crack, warped and deformed, which is more suitable for furniture feet and door frames.

The texture of eucalyptus is soft, easy to process, its coloring power and paint performance are very good, shrinkage is small, not easy to deformation, so it is very suitable for surface mosaic.

(3) Southern wood

There are many kinds of wood in the south, such as beech wood, beech wood, paulownia wood, paralyzed beech, eucalyptus, etc. These woods are fine in texture, dense in structure, and strong in strength. Wood is also relatively hard and generally suitable for furniture.

(4) White Pelicans and Red Pelicans

In the current home decoration, ash is the mainstream of the entire decoration market because of its low price and uniform color. However, it also has the disadvantages of large patterns, inelegable wood, and yellowish color. Therefore, white peony and red peony grow gradually. The ground was promoted. The red dragonfly and the white dragonfly are all woods belonging to the genus Polygonaceae. The annual rings are clear, the material is bright and full, the red dragonfly has a darker color, and the white dragonfly has a lighter color.

2, the purchase of wood

Since consumers themselves are laymen, the choice of wood is often not known, and eventually buys inferior products. So, what should we pay attention to when selecting wood?

(1) Note the moisture content

The moisture content of generally qualified timber should be between 8% and 12%. Only in this way, cracking and warping will not occur during use. The moisture content of the timber is directly related to the drying method. At present, the wood drying methods include drying method, baking method, and steam method. Among them, the steam method has the best drying effect. When people purchase wood, it is best to carefully Ask the wood which way to dry it. Although consumers do not have specialized measuring instruments, it is also possible to use relatively simple methods to measure the moisture content of the wood. For example, by hand-squeezing, by gently weighing a number of wood materials, the wood material with a small moisture content will be lighter, and the wood material with a high moisture content will be heavier. Second, you can also put the palm of your hand on the surface of the wood and feel the moisture of the plate.

(2) Note the measurement of volume

At present, some unscrupulous merchants intentionally injure consumers in the market of building decoration materials. The most commonly used method is to fraudulently measure. According to the relevant standards, the wood width should be removed within the length of the wood when measuring wood. The narrowest inspections at the ends of each 15 centimeters, but they often choose to check in the middle of sawn timber, thus increasing the calculated volume of wood.

Others use a tool that is not in line with the national technical supervision department to measure at the time of surveying, using a measure of 19 feet or 28 feet. Consumers do not have to deceive, it is best to carry rulers and calculators when selecting wood. In this way, even if some unscrupulous traders do their own tricks on the ruler, they can bring it up to compare one set, and after personal calculations, they can avoid being deceived to a certain extent.
