Moisture content is not intuitive but important
Some consumers have reported to reporters that their own solid wood floors have not cracked for more than a year, but they have cracked. However, they usually pay attention to protection. How can such a phenomenon occur? In fact, not only solid wood flooring, but also some solid wood furniture, doors and windows, and so on, and the most direct cause of this phenomenon is the moisture content of wood.
Under normal circumstances, wood itself contains a certain amount of moisture, so it will be dried before making furniture. This is well known, but drying must follow certain standards, even if the moisture content and use of furniture materials The average moisture content of the regional atmosphere remains consistent. When buying 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.
Due to different geographical locations, the average moisture content in the atmosphere will be different. Therefore, different regions have different requirements for the moisture content of wooden furniture. For example, the average moisture content of air in Beijing is 11.4%, while that in the southern region is 14% About, the specific requirements for furniture are between plus and minus 1 of the local average moisture content, Li Jiguang told reporters. The moisture content directly affects the quality and use of wooden furniture, especially solid wood furniture. When the moisture content is low, the wood will absorb moisture in the air, causing the furniture to expand and deform; and when the moisture content is high, the furniture will face the risk of cracking. Generally speaking, wooden furniture, especially solid wood furniture, preferably has a moisture content lower than the average moisture content of local air, for example, one to two percentage points. In the Beijing market, there are many products of wood from the south, or directly produced and shipped from the south. It is conceivable that the air in the south is more humid than the north, and the moisture content of the wood there is higher than that in the north, so the south The wooden furniture, especially the solid wood furniture and wood must be treated with strict moisture removal, and there are two problems in this, one is the construction technology requirements, and the other is the cost requirements. If the coordination between the two sides cannot be guaranteed in the end With effective treatment of moisture content, southern wooden furniture is indeed more prone to problems in the northern environment.
Choose wooden furniture from the details
Although the moisture content of the wood is to be measured by the detector, consumers can still be tested by some simple methods. Li Jiguang said that consumers can touch the surface of the wooden furniture with their hands, if there is a sense of moisture and cold Sense, indicating that the moisture content of furniture may be high. However, because consumers are seeing samples placed in the store for a certain period of time, most of the moisture content is close to equilibrium, so if you are not worried about the moisture content of the furniture, the new furniture still needs to be measured by a professional tester.
In addition to the moisture content, Li Jiguang told reporters that when buying wooden furniture, you need to pay attention to other details.
The first is the tenon structure of the furniture. For example, the table can be shaken by hand to see if it is stable; the sofa should be seated and shaken. If it is inactive, soft, or silent, it indicates that the tenon hole structure is relatively firm. Secondly, when buying wooden furniture, don't just look at the smooth surface paint, but also touch whether the coating is thick. If the paint film is too thin, the heat resistance and scratch resistance of the furniture will decline. In addition, we must pay attention to the paint film at the corners. The corners should not be straight and right-angled. The door of the furniture should also be painted with lacquer. The unpainted sheet is easy to bend and unsightly.
In addition, check whether the furniture veneer is flat and look at the light. It may not be easy to see it without the light. And the edge banding is uneven, indicating that the inner material may be wet, and the edge banding may fall off in a few days. Edge banding should also be rounded, not right-angled. Edges sealed with wooden strips are prone to cracking.
