Second, catalpa bungeana
(1) Advantages:
1, mass
Juglans mandshurica used to be hard miscellaneous wood, with moderate density, excellent toughness, good processability, difficult cracking and deformation, and good wear resistance. However, the arrangement of brown eyes is dim, dark substances are soft and dim, tracheids are thick, wood rays are obvious, and it is not easy to dry. The processing difficulty is definitely higher than that of other wood, and the price is also expensive.
Step 2 show up
From the appearance, Juglans mandshurica is not particularly outstanding. Juglans mandshurica doesn't have the dramatic mountain shape of beech, the golden color of teak and the tortuous texture of old elm. However, Juglans mandshurica has another elegant taste. Its plain texture is like running water, clear and uniform, with few knots. Its simple and unpretentious features are very compatible with the pastoral style. Now catalpa bungeana is used as pastoral furniture in the market. Wood has moderate hardness and weight, physical and mechanical properties such as dry shrinkage, smooth planing and strong wear resistance, and fine and uniform structure.
3. Juglans mandshurica used to be hard miscellaneous wood, which is very effective in making furniture, but it must be more difficult than other wood processing. Nice texture. It is very popular now. According to the historical records of Ming and Qing Dynasties, Juglans mandshurica was the first choice of utensils at that time, and it was the material appreciated by the world. The furniture made by it not only has the characteristics of practicality, appreciation and appreciation of mahogany furniture, but also has the quality that mahogany can not achieve because of acclimatization, cracking, deformation and cracking. So it can be preserved for a long time. In addition, the advantages of Zimu furniture are also reflected in the relative value. For precious wood such as Phoebe bournei, the price of Zimu is relatively peaceful and many people in the family can afford it. The collection and use price is also excellent.
(2) Disadvantages:
1, beech furniture is a kind of all-solid wood furniture, its hardness is not as good as some high-grade plastic furniture and iron furniture, so beech furniture cannot collide with hard objects;
2, eucalyptus furniture should avoid high temperature, solid wood furniture is more afraid of high temperature, if it reaches the fire point, it will burn, causing safety problems;
Third, nanmu:
(A) Advantages
Nanmu furniture, as a domestic high-grade furniture, has obvious advantages and disadvantages, and the advantages outweigh the disadvantages. Comparatively speaking, the shortcomings of nanmu furniture are somewhat insignificant.
1, strong corrosion resistance
Nanmu is a subtropical tree with a growth cycle of hundreds of years, so it is extremely precious. Nanmu has excellent corrosion resistance. Even in extremely hot and humid environment, nanmu furniture will not be oxidized and corroded. Therefore, nanmu has been widely used to make furniture since ancient times.
2, strong insect resistance
As we all know, it is a common phenomenon that wood is eaten by insects, and it is also the biggest natural enemy of wood. Nanmu is easy to be eaten by insects during the growth period, and once it is mature, its wood contains a unique fragrance and has the function of repelling mosquitoes, so Nanmu furniture has strong insect resistance.
3. Good cold tolerance
Nanmu itself is mild, and it is not cold even in winter. Nanmu furniture has dense wood and its internal temperature is less affected by the external environment, so it also has good cold-proof performance in winter.
4, not easy to deform
The growth cycle of nanmu for hundreds of years leads to the dense wood of nanmu, so nanmu furniture made of nanmu rarely deforms or cracks, which is the characteristic of furniture made of other materials.
(2) Disadvantages
Compared with its advantages, the disadvantages of nanmu furniture are unremarkable. At present, nanmu furniture can be called a feature of shortcomings, or its weight is much heavier than ordinary furniture, and the price of nanmu furniture is not affordable for ordinary consumers.
