Wood material identification, the authority of wood identification

Wood material identification generally needs to be carried out according to the following aspects:

1.Observe the color: There are significant differences in the color of different types of wood. For example, teak is yellowish brown or reddish-brown in color, red sandalwood is purple-red or black-purple, camphor wood is yellowish-white, and so on.

2.Observe the texture and structure: The texture and structure of the wood are also an important basis for judging its species. For example, oak is usually coars-grained, while boxwood is finer-grained.

3.Smell: Many woods emit their characteristic odors when they are cut or wiped. For example, pine wood has a strong fragrance, cherry wood has a faint fruity fragrance, and boxwood wood has a faint sweet fragrance.

4.Feel the weight and hardness: In general, hardwoods are heavier than softwoods, and they have a dull sound when struck. Pressed with your fingers, the hardwood will not lose its shape by all.

5.Grinding facets: Sanding the facets of wood allows you to see its grain and color more clearly.

6.Laboratory analysis: In some cases, it may be necessary to perform a precise analysis of wood by means of laboratory tests, such as microscopy to observe its cellular structure, or non-destructive testing using near-infrared spectroscopy.

The above are some of the common methods for wood material identification. It should be noted that because the color, grain and other characteristics of wood may be affected by environmental factors and individual differences, multiple factors should be considered as much as possible in the identification, or a professional wood inspection agency should be entrusted for identification.

Summary. The authority for timber identification is the National Furniture Quality Supervision and Inspection Center.

The authority for timber identification is the National Furniture Quality Supervision and Inspection Center.

It is a furniture and indoor environment quality supervision and inspection agency prepared by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, and has drafted a number of national air standards and industry standards, mainly to carry out all kinds of furniture, tree species identification and furniture flame retardant test testing, is a domestic state-level supervision and inspection agency.

I bought a piece of wood from Bai Qi Nan in Nha Trang, but the appraisal book says Bai Qi Nan.

It is located at No. 4, Dahongmen West Road, Beijing.

I would like to ask if this is true or not.

You can also go to the local quality and technical supervision department to identify.

You can't tell if it's true or not.

1. Look at the texture that is, look at it with your eyes, mainly look at two points, one is the texture, mainly look at the section of the floor, the texture of different wood species is different, but the texture of the same wood species is generally the clearer the better. The second is the process, to see whether the board surface is smooth and whether the technical process of the tenon is conducive to the joint of the floor. Under a magnifying glass, the texture of the floor will appear clearer, and neither the real grain nor the imperfections of inferior wood can be hidden.

2. Smell the smell of wood that is, use the nose to smell the smell of wood from the side groove of the floor, the smell of different wood is obviously different, such as the authentic balsam dalvo (commonly known as red sandalwood) has a strong sandalwood fragrance, which has the effect of repelling mosquitoes and insects. 3. Ask the place of origin that is, ask the clerk in detail about the wood species and flooring, such as the origin, characteristics, moisture content, etc. 4. Weigh the weight of the floor by hand, and use the same wood species of wood floor, the weight is generally the same.

5. Look at the paint surface under the magnifying glass Again, the paint determines the color, grade, environmental protection and service life of the floor. In order to achieve an aesthetic effect, almost all lacquered panels add color essence to their paints to make the floor more colorful. The more color essence, the smaller the color aberration, and the more distorted and unnatural the color is.

It is not good to paint too thick or too thin, too thick will make the floor lose the original flavor of the wood, and too thin will reduce the wear resistance factor.

Summary. Hello dear, happy to answer your <>

The material of the wood can be identified Through the texture and appearance of the wood, the wood species can be quickly identified, observed by the naked eye or with the help of a magnifying glass (ten times), and can also be judged by the morphology of the growth rings, wood rays and pith core, and for the board, different tree species can be identified by the shape of the radial cut board or chord cut pattern and the distribution of wood rays and ducts. 2. Use the macroscopic structure of wood, the microstructure of wood, the physical energy of wood, the mechanical energy of wood and other theories to further identify

Can the material of the wood be identified?

Kiss Wood material identification is mainly based on the physiological quality of wood species to correctly identify wood. The basis for the identification of the material material identification variety, mainly to grasp the physiological characteristics of various trees, bark, texture, wood se is the main basis for identification, look at the texture: that is, with the eyes, mainly look at two points, one is the texture, mainly look at the section of the floor, the texture of different wood species is different, but the texture of the same wood species is generally the clearer the better.

Smell the smell of wood: that is, use the nose to smell the smell of wood from the side groove of the floor, the smell of different wood is obviously different, that is, ask the clerk in detail about the wood species and the floor, such as the origin, special xing, moisture content, etc. Weighing weight:

That is, personally check the weight of the floor with your hands, and the weight of the wooden floor of the same wood species is generally the same. Look at the paint surface under the magnifying glass: it is the paint again, and the paint determines the appearance, grade, environmental protection and use of the floor

Hello dear, you can judge by the weight, oil content, and color of the wood. They are as follows:1

Whether the wood is heavy and hard: The stability of heavy and hard solid wood flooring is generally better than that of light and soft solid wood flooring, which is prone to expansion. For example:

Ironwood, heavy ant wood, disc bean, acacia wood, and lattice wood are heavier and harder than ash (ash) and filiform jade, and the solid wood floor is not easy to deform, while the firulature and ash often appear in the gap or local arch after the year. Therefore, you can choose solid wood flooring according to the air-dry density of solid wood flooring on the manufacturer's information, and the solid wood flooring with air-dry density above is generally heavier, harder and more stable. 2. Whether the wood contains oil:

The material is not heavier and harder, the better, too heavy, hard wood surface is prone to fine cracks (not between the boards), and the solid wood floor with an air-dry density above should be careful. However, if the wood contains oil (unpainted boards, sawn surfaces feel oily), the stability is better. Iron wood is prone to fine cracks because it does not contain oil, except for the first floor, try not to pave.

The heavy ant wood and disc bean solid wood flooring have good stability because of the oil content. 3. Whether the natural color of the wood is neutral and light: the stability of heavy ant wood and twin leaf sumu is good, but the natural color is dark and the color difference is large, so there are two problems:

First, there is a big gap between the actual solid wood floor and the sample, and second, the color is single, that is, dark. Oak and other natural colors are light, and can be processed into many colors, and the color difference is also small. Disc beans and lattice wood solid wood flooring are also OK.

Are you there? Hello, the wood can be identified.

Would you like to recommend a few companies?

What kind of wood is this?

Explain what you mean.

Didn't you say that wood can be identified?

Identification of timber is done by a professional organization, and my side is a problem platform, not an appraisal agency, please understand

If you have any other needs, please explain them before **.
