Extended data

(1) hand balancing method. Gently weigh a number of pieces of wood, the wood with small water content will be lighter, and the water content of wood will be larger.

(2) Touch by hand. Lay your palm flat on the surface of the wood to see how wet it is.

(3) Knocking nails. Knock in wood gently with long nails. Wood that is well dried is often easy to nail in, and wood that is wet is more troublesome to nail in.

When choosing wood, be sure to carry a ruler and calculator with you. Some unscrupulous merchants are likely to cheat on these two things, and they can compare them by bringing one set with them, so as not to be fooled. When calculating the volume of wood, you should pay attention to accuracy. Some merchants will give you a little less in length and a little more in width and thickness. On the surface, you think it is even, but when you actually calculate it, you will find that you have suffered. Therefore, it is best to be accurate when calculating, so as to avoid trouble.

All kinds of wood grades 2 What kind of wood is good for solid wood furniture?

1 pine

Now everyone attaches great importance to environmental protection, and solid wood furniture is on the main stage, among which pine furniture accounts for a large proportion. There are two kinds of common pine furniture, the first is Finnish pine furniture, and the second is New Zealand pine furniture. Finnish pine, also known as "Nordic red pine", is an artificial forest in Finland.

Finnish pine grows in cold zone, and its growth cycle is relatively slow. However, the wood is stable, has the characteristics of physical compression resistance, shear resistance and strong nail grip, and the furniture has obvious texture and fine and beautiful texture. It is a best-selling wood and is mostly used in children's furniture. New Zealand pine is native to California. Because of the good living conditions of the island country, it has become one of the representatives of New Zealand.

Advantages: low price, natural and environmental protection, not easy to deform, clear and beautiful texture.

Strong elasticity and air permeability, good thermal conductivity and simple maintenance.

Disadvantages: the wood is soft and easy to crack, not resistant to bumps and can't bear too much weight.

2. Fraxinus mandshurica

Fraxinus mandshurica is harder and more wear-resistant than pine, and more affordable than mahogany. It has beautiful and clear texture, good corrosion resistance, good water resistance, easy processing, great toughness and good coloring performance, so it is one of the good choices for decorative performance. The color of Fraxinus mandshurica is yellow after being brushed with clear oil, and it is often chosen in previous years, so everyone thinks that Fraxinus mandshurica is not high-grade enough and is tacky. It is suggested that when it is used as solid wood material, bleaching process can be selected to make the color of Fraxinus mandshurica lighter; You can also use clear mixing treatment to make the wood grain dyed black or white to show its modernity.

Advantages: good processability, and can be fixed well with nails, screws and glue.

Good surface effect can be obtained by dyeing and polishing.

Disadvantages: there is no decay resistance of heartwood. It should be noted that,

White wood is easily eaten by pink beetles and common furniture beetles, and it is not easy to dry and prone to warping.

3. Oak (White Oak, red oak)

Oak is mainly produced in Europe and North America, and a large number are produced in Russia and the United States. It is also a popular wood for decoration and furniture making. Oak is characterized by hard and straight texture, coarse structure, elegant color and beautiful texture, good mechanical strength and wear resistance, but it is not easy to dry, saw and cut.

Oak has a high grade, which is suitable for making European furniture and Chinese classical furniture, giving people a dignified and calm feeling of mahogany furniture, but the price is lower than mahogany furniture. In addition, due to the fine texture of oak, there are many infiltrates in the pipe holes, which are not easy to absorb water, corrosion-resistant and strong, so European and American countries often use it to make wine barrels to store red wine.

Advantages: Oak wood is hard, natural and clear mountain-shaped texture, which makes furniture more stable and durable.

Oak has good processability and is suitable for making European style furniture.

Disadvantages: Under the condition of immature manufacturing technology, oak furniture is prone to deformation and cracking.

In addition, the amount of oak wood in China is small, and at present it mainly depends on imports, which leads to the high price of oak furniture.

The ranking of wood grades is from low to high.

1 pine

Pine, as one of the most common furniture materials, has always been loved by everyone. Its biggest advantage is that it is cheap, and it is a good and cheap choice.

2. Rubber wood

Rubber wood is a kind of wood that has emerged in recent years, and most of it exists in the form of finger-joint plates. This kind of wood is fine in texture and fine in fiber, and it has good effect whether it is carved or colored.

3. Elm

Ulmus pumila is a traditional furniture material in China, with hard texture and beautiful patterns, and it has a good effect without coloring.

4. Fraxinus mandshurica

Fraxinus mandshurica and ash are actually one thing, but in recent years, imported Fraxinus mandshurica are collectively referred to as ash. The biggest advantage of this kind of wood is its beautiful pattern, which is suitable for environmental protection coatings such as wood wax oil.

All kinds of wood grade 3 high-end wood

Fraxinus mandshurica: It is produced in northeast China and the former Soviet Union. The price of Russian Fraxinus mandshurica is higher than that of northeast Fraxinus mandshurica, but its performance is not as good as that of northeast Fraxinus mandshurica. Because of our wood protection, there are few northeast Fraxinus mandshurica at present. We use Russian ash. Specifically, the color of Russian Fraxinus mandshurica is darker than that of northeast Fraxinus mandshurica.

Oak wood: produced in the northeast of China, the wood is hard, and the wood grain is very similar to that of red oak. Many merchants use oak wood to impersonate red oak. At present, there are two rural businesses in Nanjing that pretend to be red oak with oak wood. One of them is still pretending, and the other has reluctantly admitted that he is oak wood without naming and criticizing. The market price of oak wood is similar to that of manchurian ash.

Mid-range wood:

Rubber wood: domestic rubber wood and Southeast Asian rubber wood. Generally speaking, rubber wood in Southeast Asia is superior to rubber wood in China, and rubber wood in Malaysia is the best. Rubber wood is white in color and hard in wood, which is an ideal material for furniture. The disadvantage is that it may turn yellow if it is not treated. If the primer is not well prepared, moths may occur (this situation is rare, but it is not ruled out. White wood is the most susceptible to moth, followed by maple.

Cedar is a precious tree species and a second-class protected plant in China. It has beautiful texture, tough texture, fresh fragrance and bright color, and is most suitable for making solid wood furniture. Cedar wood is rich in oil and has a special fragrance. Its main aromatic components are triterpenes and limonoids. Cedar wood can be used as an important raw material for making Tibetan incense. The furniture made can not only prevent insects but also soothe the nerves and nourish the heart. Its environmental protection is world-famous, so it has been designated as environmental protection furniture by the United Nations Department of Humanities and enjoys the reputation of "living and breathing furniture".

Teak: Except Thai and Burmese teak. At present, the red roses and yellow roses used in Nanjing market are what we call teak.

Beech: At present, beech used in Nanjing market is beech in Myanmar, commonly known as water melon.

Betula alnoides: produced in Yunnan, Myanmar. At present, cherry wood is generally impersonated by Betula alnoides.

The upper middle-end wood is rubber wood from Malaysia.

Low-end wood.

Betula northeast: Betula northeast mainly includes Betula platyphylla and Betula platyphylla. It belongs to the general tree species, and its origin is Northeast China. Generally speaking, white mixed water furniture is made of northeast birch, and some merchants pretend to be other good wood. I have a look at IKEA's solid wood furniture, most of which are birch furniture. Interested TX can go and observe it.

Basswood: with good finish, it is generally used for drawers and bed boards of high-grade furniture.

Cinnamomum camphora: many owners named the wardrobe back plate material. In fact, the price is slightly higher than that of cedar, and my attitude is that camphor wood is not recommended for the whole backboard.

Pinus sylvestris var. mongolica: Compared with southern pine, Russian Pinus sylvestris var. mongolica has a hard texture. Because of its short service life, many owners use Pinus sylvestris var. mongolica furniture with high cost performance.

Low-grade wood

Southern pine, cedar, etc. (fish that love bullfrogs)
