The scientific name and common name of common solid wood slabs in the market, and the introduction of wood properties

Is Brazilian rosewood a rosewood?

Is the scientific name of Okan's tree species really melancholy?

Is South American walnut walnut?

What is the density?

What is the scientific name of Wujinmu tree species? What are the characteristics of woodiness?

What kind of "ebony" does ebony refer to?

Why do we keep asking about the "scientific name" of the tree species?

The common name can be taken casually or countless, and only the scientific name is its only counterpart. If you don't even know "who" it is, how can you understand and evaluate it in this era of mixed information? Look at the appearance, every big slab is painted shiny and shiny; weighing weight, every big slab is heavy (after all, they are big, even the pine wood is hard to handle); listening to the name, each one is noble and magnificent: Huali, Wujin, Ebony...how to choose?

Listen to the introduction of the business?

A domestic solid wood unicorn-level company introduced in crowdfunding: XX walnut, a rare and precious wood recognized in the world, is the king of hardwoods.

Do you believe it?

1. Brazilian rosewood

When it comes to slabs, the first thing many people think of is the slabs with huge diameters and dazzling textures. Brazilian rosewood, also known as "Brahua" and "Bus Flower", can be understood literally that it is "Brazilian rosewood". This is a logical understanding, and it is also a mistake that most consumers make.

In fact, it is neither a pear, nor is it produced in Brazil.

The real "rosewood" refers to the Pterocarpus-rosewood in the national standard of "Redwood", including 5 species:

Andaman red sandalwood (rare in the domestic market)

Big fruit red sandalwood (commonly known as Burmese rosewood)

Hedgehog red sandalwood (commonly known as African rosewood)

Cystic red sandalwood (rare in the domestic market)

Indian rosewood (commonly known as Indian rosewood)

And the Brazilian rosewood on the big board market is the collective name of the three tree species in the [Paraphyllum genus], the international trade name Bubinga, including:

Guibourtia demeusei (Guibourtia demeusei)

Pellegrini Gu Yi Su (G.pellegriniana)

G. tessmannii

Mainly produced in Africa, Cameroon, Gabon and other places, these three types of wood are collectively referred to as Bubinga in the international timber market. In addition, the Gabonese will also call the Gabon origin Kevazingo, which means that the patterns of the Gabon origin are better and more dazzling. Air-dry density (when moisture content is 12%): about 925kg/m³. The shrinkage is smaller and the stability is better.

Second, Okan solid wood slab

In Baidu Encyclopedia and many other online materials, they are all called: Okan, the scientific name of citronella.

The pineapple, commonly known as the pineapple grid in the Chinese market, is mainly used in Southeast Asia such as Indonesia, Malaysia, and Papua New Guinea. It is a huge difference to make the Okan from Africa into the "season" inexplicably.

Okan, the scientific name of the Gabonese disc bean, the English name: Okan, a large tree, up to 50m high, up to 1.0m in diameter, distributed in tropical regions of West Africa. It is mainly imported from Gabon, Cameroon, Congo and other places, and the quantity is relatively large. The difference between the heartwood and sapwood is obvious. The heartwood is golden brown with a greenish tint, and turns to reddish brown for a long time, with dark pinstripes, and the sapwood is light pink.

The price of African Okan solid wood is lower, the wood is shiny, and the raw material has a peculiar smell. The texture is staggered, the structure is slightly thicker, the weight is hard, the strength is high, and the air-dry density is greater than 1.0g/cm3. Large shrinkage, slow drying, slight cracking and deformation.

Three, African chicken wing wooden slab

African wenge, scientific name African cliff peas, Latin name: Millettia Laurentii, is mainly produced in the Congo Basin of Africa. The air-dry density is 0.80-0.91g/cm3, the national standard tree species of "Redwood".

The wood grain is in the shape of a fine flower cloud, which resembles chicken wings. Especially in the longitudinal section, the wood grains are slender and floating, changing endlessly, naturally forming landscapes and figures.

4. South American walnut (rain tree)

South American walnut is a kind of wood produced in South America, the scientific name is rain tree, and the Latin scientific name is Samanea saman (Jacq.) Merr.

The structure is relatively coarse, with an average density of approximately 0.65 g/cm3. The diameter section is dark brown with black stripes, and the texture is wavy.

According to the records of Flora of China, the wood of the young rain tree is soft, while the old tree is hard and can be used as a wheel. Native to tropical America, it is now widely planted in tropical regions, and introduced in Taiwan, Hainan and Xishuangbanna of Yunnan.

5. Ebony (leather ash wood)

The wood called ebony in the large-board lumber market, "skin ash" is the most common type, and most of the wood that enters the domestic market is produced in Mozambique. The scientific name of windmill wood, the Latin name: Combretum imberbe is generally called "leather gray" in the log market, and it is mostly called [Ebony] in the finished product market of furniture and crafts.

The wood is hard and heavy, and the air-dry density is about 0.91-1.10g/cm3. Luster, slightly oily and sexy. Interlaced texture; fine structure; very heavy and hard; high strength. It is difficult to process, the diameter surface is slightly fluffy; the wear resistance is strong; the nails are easy to crack, and the holes must be drilled first. Slow drying and easy to crack, air drying is best.

Six, ebony wood slab

Ebony wood, the former "zebra wood", was imported from Africa and used in furniture, flooring and other materials, but it was unknown and unknown for a long time. It was not until someone gave it the famous name "Wujinmu" to replace the original "zebra wood", that it was promoted vigorously by many well-known furniture brands, and it was in the limelight for a while.

In fact, "zebra wood" is also a general term, and the specific tree species are divided into two types of wood: "big zebra wood" and "big zebra wood". ", scientific name: Shoe dani, Hematoxylinaceae, spp., Latin name: Microberlinia spp, produced in Nigeria, Côte d’Ivoire, Gabon, Cameroon and other African regions. The air-dry density is 0.73～0.88g/cm^3.

The scientific name of "little zebra wood": Shoe dagger, hematoxylin genus, Latin name: Paraberlinia bifoliolata, produced in Cameroon, Gabon, Equatorial Guinea and other countries. The air-dry density is about 0.7g/cm3. The biggest advantage of ebony wood is its natural texture. In the natural wood color, the golden and black curves are intertwined, not only the color is eye-catching, but also the visual sense is very fluid.

The tree species information of the big zebra: the radial shrinkage rate is 7.6%, the chord shrinkage rate is 10.8%, and the dry shrinkage rate is relatively large.

The disadvantage is that it has poor drying shrinkage and stability, and changes in moisture content can easily deform and crack, and cannot adapt to wet or dry environments. And in the process of drying and processing, it often bursts by itself, and the stability of the wood also discourages many manufacturers.
