Chicken Wings Overview

Chicken wing wood is a general term for wood with a black or corn-brown heartwood and the same depth of the wood surface as a tree species with a chicken wings pattern. In the taxonomy, the wenki wood includes the dark-hearted wood species of the genus Athyrium and the genus Helix.

The conditions for the definition of chicken winged wood in the mahogany standard: the trees with dark heartwood in the genus Asclepias and the genus Athyrium have an air-dry density of greater than 0.8g / cm3 and an average chord diameter of less than 200μm. In addition to itself, chicken wing wood also includes African cliff bean wood, Baihua cliff bean wood, and iron sword wood. Sawtooth wood is produced in Southeast Asia and southern China. Cliffwood is produced in Southeast Asia and Africa. The density, structure and patterns of wood produced in Southeast Asia are better than that of wood produced in Africa.

Burmese chicken wing wood is actually Baihuaya bean wood produced in Myanmar and Thailand. The heartwood is dark brown or chestnut brown, often with black stripes; the tube holes are visible to the naked eye; the density is large and sinks in water; the material is smooth and delicate. The heart of the tree has a sand stone core, that is, something similar to sand stone, and the radial pattern extends outward from the tree heart. This sandstone heart is extremely hard, and sometimes it will collapse. The proportion of sandstone cores in the entire tree varies from 20% to 50-60%. The maturity of Burmese chicken wing wood is about 150-200 years. At this time, most of the diameter can reach 30-40 cm, and the thicker can reach 60-70 cm, but it is rare. In order to buy a good price on the market, it is also called "old chicken wing wood".

Burmese chicken wings are maroon. If you cut it into a right-angled cross section, one side will have chicken wings, and the other side will not. . Burmese wenge has very few straight trees, so the yield is low. Because of its high density, it sinks in water. The processing is also difficult, and if it is not properly dried, it can be easily modified. Beijingers are accustomed to call Burmese chicken wing wood the old chicken wing, which is the top grade of chicken wing wood.

Identification of chicken wing wood furniture

First, let's talk about the difference in tree materials: from the color point of view, Burmese wenge is chestnut. If you cut it into a right-angled cross section, one side will have chicken wings, and the other side will not. The most obvious sign is that the tree heart of Burmese wenge has a sand stone core, that is, something similar to sand stone, and the radial pattern expands outward from the tree heart. This sandstone is very hard like a heart, and sometimes it will fall apart. The proportion of sandstone cores in the entire tree varies from 20% to 50-60%. The maturity of Burmese chicken wing wood is about 150-200 years. At this time, most of the diameter can reach 30-40 cm, and the thicker can reach 60-70 cm, but it is rare. Burmese wenge has very few straight trees, so the yield is low. Because of its high density, it sinks in water. The processing is also difficult, and if it is not properly dried, it can be easily modified. Beijingers are accustomed to call Burmese chicken wing wood the old chicken wing, which is the top grade of chicken wing wood. In contrast, African chicken wing wood is larger and straighter, the material is soft and crisp, gray chestnut, the color of the finished product is slightly yellow, the tube hole is slightly thick, the hardness is slightly worse, the specific gravity is lighter, so it does not sink in the water. The tree heart has no sand stone heart.

How do ordinary consumers identify two different materials from the finished product? One is to look at the finish. Burmese chicken wing wood is smooth and delicate, while in African chicken wing wood, those very delicate patterns cannot be carved with it. The second is the specific weight. Burmese wenge feels particularly heavy. The third is to distinguish product types. Because Myanmar chicken wing wood has less material, it is mostly used for making sofas and Ming-style furniture. The African chicken wing wood has a large raw material itself and can do anything. It is particularly important that if you buy wenge products, you must let the manufacturer indicate which kind of wenge is in the contract as a basis.

Chicken wing wood's usual maintenance method

1) Rub the surface firmly with a towel. The function is actually to clean the wax layer and dirty color of the surface and to re-polish. About 2-3 hours per day for two to three days.

2) Rubbing with a soft cotton cloth for a week is also considered polishing. At this time, there will be traces on the surface of the soft cloth. This is normal, and the color will fade after a week.

3) Leave it for one week naturally. Let the beads dry naturally, and the surface is evenly contacted with the air to form a fine and uniform oxidation protection layer.

4) Start the hand plate. At this time, the hand must be just washed and dried. Please do not plate directly for sweaty hands. Note that the hole must be plated. It can be plated for about 30 minutes a day, from one week to two weeks Afterwards, you can feel the sense of stickiness, but in fact it has formed a thin layer of paste.

5) At this time, it can be placed for a period of time and then dried naturally, and the package slurry is hardened to a certain degree, usually about a week.

6) Repeat the process of 4 and 5 5 to 6 times, that is, 3 months. You will see a very lustrous luster, and sometimes the disk will show a strong reflection, some like glass luster.

Special attention is needed: if it is dirty, it can be wiped with a slightly damp cotton cloth several times, and then placed for a period of time before playing. All areas should be tried as much as possible during the disc, especially the orifice disc is the most taboo is quick success You can only come slowly one process at a time. With the changes, you can also get a spiritual pleasure at the same time.


R410A is an HFC blend designed for new R22 applications. It operates at higher pressures than many other refrigerants, and so cannot be used to retrofit R22 systems. Systems designed for R410A can take advantage of its ability to use smaller components, making it a key refrigerant for domestic and light air conditioning equipment. R410A's low glide also makes it suitable for some centrifugal compressors, and it can operate in low temperature applications.
