The main role of furniture in modern homes is wooden furniture, in which solid wood furniture occupies the main battlefield of high-end consumption, but most people often only look at styles and plates when purchasing wooden furniture, while others are concerned about the quality of furniture. The details are half-resolved or indifferent. In fact, when purchasing wooden furniture, especially solid wood furniture, the moisture content of wood, the processing of paint film, the connection of concrete structure, etc. are all places that should pay more attention. Li Jiguang, deputy stationmaster of timber furniture quality supervision and inspection station, reminds consumers. Especially when you choose off-site wood, it should be said that the moisture content of wood has a great relationship with the intrinsic quality of furniture.
Water content is not intuitive but important
Some consumers have told reporters that their own solid wood flooring has not been used for a year, and cracking has occurred. However, they usually pay attention to protection. How can this happen? In fact, not only solid wood flooring, some solid wood furniture, doors and windows, etc. will also have such a phenomenon, and the most direct cause of this phenomenon is the moisture content of wood.
Usually, the wood itself contains a certain amount of water, so it will be dried before the furniture is made. This is well known, but the drying must follow certain standards, even if the moisture content and use of the furniture materials The average moisture content of the regional atmosphere remains the same. When purchasing wooden furniture, especially solid wood furniture, if there is no professional detector, it is difficult for consumers to know whether the wooden furniture meets the prescribed standards. However, we cannot ignore the importance of water content because it cannot be visually reflected.
The average moisture content in the atmosphere varies depending on the geographical location. Therefore, the water content requirements for wooden furniture vary from region to region. For example, the average moisture content of air in Beijing is 11.4%, compared with 14% in the south. Left and right, specific to the requirements of the furniture is the local average moisture content between plus and minus 1, Li Jiguang told reporters. The water content directly affects the quality and use of wooden furniture, especially solid wood furniture. When the water content is low, the wood will absorb the moisture in the air, causing the furniture to expand and deform. When the water content is high, the furniture will be in danger of cracking. In general, wooden furniture, especially solid wood furniture, preferably has a moisture content that is a little lower than the average moisture content of the local air, for example, one to two percentage points. In the market in Beijing, there are many products of wood from the south, or directly from the southern production and then shipped, it is conceivable that the air in the south is damp than the north, where the moisture content of the wood is higher than that of the north, so the south The wooden furniture, especially the solid wood furniture and the wood, must be subjected to strict moisture treatment, and there are two problems in this. One is the requirement of construction technology and the other is the cost requirement. If the coordination between the two aspects is not guaranteed In the case of effective treatment of water content, southern wooden furniture is indeed more prone to problems in the northern environment.
Choose wooden furniture to start from the details
Although the moisture content of wood is measured by the detector, consumers can still test it by some simple methods. Li Jiguang said that consumers can touch the surface of wooden furniture with their hands, if there is dampness and coldness. Sense, indicating that the moisture content of the furniture may be high. However, since consumers see samples that have been placed in the store for a certain period of time, the moisture content is almost balanced, so if the moisture content of the furniture is not assured, the new furniture should be measured by a professional detector.
In addition to the water content, Li Jiguang told reporters that other details should be paid attention to when purchasing wooden furniture.
First of all, the structure of the furniture, such as the table, can be shaken by hand, to see if it is stable and unstable; the sofa should sit and sway, if it is not active, not soft, no sound, it means the structure of the blink is relatively firm. Secondly, when buying wood furniture, don't just look at the smooth surface paint, but also touch the thick coating. If the paint film is too thin, the heat resistance and scratch resistance of the furniture will decrease. In addition, pay attention to the paint film at the corners, the corners are not straight and right angles, and the straight edges are easy to fall off. A paint should also be painted inside the door of the furniture. The non-painted sheet is easy to bend and not beautiful.
In addition, it is not easy to see if the furniture veneer is flat when it is flat. Moreover, the edge is not flat, indicating that the inner material may be wet, and the sealing may fall off in a few days. The edge banding should also be rounded and not straight at right angles. The edges sealed with wood strips are prone to moisture and cracking.
