Hermes in the wood, so you are such a South American black walnut!

How can you not let go?

More and more people are beginning to favor black walnut furniture. As a precious wood in the United States and South America, it takes about 50 years from growth to timber. It is produced in the commercial forest areas in the eastern and southern States of the United States, and it is one of the few artificially planted and naturally regenerated trees in the United States and its surrounding areas. Because black walnut is a restricted tree species, the annual supply is limited.

Black walnut is very expensive. Furniture is generally made of wood skin, rarely solid wood.

Dark tree species have good elasticity and are very suitable for making tables and chairs. Traditional wood veneer can be used for piano surface and interior decoration of middle and high-grade cars; Very precious California black walnut bark, used for the interior of more upscale Mercedes-Benz, BMW and other cars or the decoration of senior clubs.

? Black walnut has excellent paint and dyeing properties, and excellent surface can be obtained after polishing.

? Black walnut has good dimensional stability, and is evaluated as heartwood with strong corrosion resistance, which is the most durable wood even in corrosive environment.

? The density of black walnut is 0.66-0.68, and the density of mahogany is 0.72, so black walnut is durable, not easy to crack, and can stand the baptism of years.

These unique characteristics make black walnut very valuable, so 100% solid wood furniture made of black walnut is naturally more valuable than other general furniture.

So how to distinguish black walnut furniture? In fact, identifying black walnut furniture is largely related to identifying solid wood furniture.

Pay special attention to the moisture content and origin of Furniture wood. The climate in different regions of China has an influence on the moisture content of wood, and the moisture content of wood should not be higher than 65438 0% of the local equilibrium moisture content in the use area, otherwise the wood will easily be separated from the tenon and mortise, and the furniture will fall apart and warp due to large expansion and contraction. There is an old saying that "solid wood can't cross the Yangtze River", that is to say, solid wood furniture produced in the south will crack and deform easily when it reaches the north because of the climate. So when shopping, you should see the place of origin clearly.

Tips: It is difficult to make solid wood furniture and identify it. It is difficult for ordinary people to correctly identify, even professionals, not everyone can correctly identify. Usually, destructive sampling is needed to make a final determination. Therefore, I can't give you any really valuable identification methods here. And it may involve many after-sales problems, so the only suggestion for everyone is to buy a bigger furniture brand and a guaranteed brand.

1. Observe whether the wood is defective.

There should be no big knots or cracks in the main stress parts of furniture, such as the columns near the ground and the bearing rods connecting the columns. The structure is firm, the frame shall not be loose, and the tenon and material are not allowed to be broken. Don't buy a "three-in-one" particleboard saw, nail and paint; Don't buy furniture made of "three noes" drawers. There are no bad edges, no tenons and no straps at the bottom. Wood-based panel components used in furniture should be sealed, and all kinds of accessories should be installed without leaking nails or piercing nails.

2. Observe the advantages and disadvantages of wood.

Open the furniture doors and drawers to observe whether the wood is dry and white, and whether the texture is tight and delicate. If you use furniture made of particleboard, density board and primary molding board, it is required that there should be no irritating smell after opening the cupboard door or drawer.

3. Are the edges, tops, front and back joints of furniture joined by tenons, tongues and grooves, or by double tenons?

Swallowtail joint or butterfly joint should be selected. Heavy furniture should be tightened and glued with protective blocks at the corners. As for the backboard, be sure to check whether the screws are embedded.

4. Observe whether the drawer or door frame is tilted, whether the mortise position is crooked or the eye hole is too large, and whether the tenon is not tight and other parts are skewed.

Wooden furniture should be safe and stable. When the two cupboard doors are opened at 90 degrees, the cabinets can't be turned forward automatically by gently pulling them forward by hand. The glass of the bookcase door should be edged; Mirrors and dressing tables should be equipped with backboards, and the glass surface should be fixed with layering.

5. Observe the strength of the plate.

The board emphasizes that you can press with your fingers to feel the fastness of the board. One side of the material should be fixed with a grid-like fixture. If the skeleton is sparse, it will feel hollow and unreal when pressed on the surface, and the panel will vibrate greatly. The drawer bottom plate should be pressed by hand to test its strength. Generally, the bottom of the partition is multi-layered, and the partition with large area should be five-layered. Cabinet doors and drawer switches should be flexible. When the panel is covered with veneer and other materials, it should be similar to the color of the complete set of products, and the paint film on the surface of the product is not allowed to wrinkle, stick to paint or leak paint.

6. Check the slide rail and bolt of the drawer.

Drawers should be strong and firm, and screws should be tightened inside. You may wish to open drawers, movable desktops, cupboard doors and other parts to ensure that you can use them freely and connect them correctly.

7. Put your hand on the surface of the furniture, and carefully check whether the polished surface is smooth, especially to avoid rough feet and other parts.

Are there stripes in the paint? Is the paint in the corner too thick? Are there any cracks or bubbles?

8. Turn the chairs and decorative furniture upside down and see how they are made.

As for the table, check it from the bottom. See if the joint is reinforced with screws and wedges. Are the slats and rungs fastened tightly? Is there any extra glue and filler at the joint?
