Relevant persons in charge of the provincial furniture quality inspection station introduced that the increasing pass rate of furniture indicates that the quality of furniture is getting better and better, but there are still some unqualified products existing on the market. Whether furniture is environmental-friendly is the most concerned issue by people. Its environmental protection index is reflected in formaldehyde emission. Unqualified formaldehyde emission means that the detected value is greater than the standard specified value, which indicates that enterprises do not strictly control the purchasing and using of major raw materials such as artificial boards, or they use glue whose quality does not meet the requirements during the production process or use excessive glue. Furniture with formaldehyde exceeding the standard is the "culprit" of indoor air pollution and harm to human health. At present, the problems existing in the quality of furniture are mainly reflected in the following seven aspects: formaldehyde emission, artificial board edge sealing, metal components material requirements, wooden components material requirements, wood moisture content, drawer slide rail strength, and the disqualification of furniture user manuals. These problems directly reflect various non-standard phenomena in the production of furniture enterprises. In addition to environmental protection, furniture making technology is also a key factor in ensuring quality. In panel furniture, panel edge sealing is the focus to see the quality of furniture. Some furniture door panels or boxes' edges are not tightly sealed and extremely easy to fall off. Worse still, some furniture panels' exposed edges are not subjected to edge sealing treatment, or the boards inside the box are not subjected to edge sealing treatment. This is the result of some small manufacturers who do not follow the standard production process in order to reduce costs and save materials and reduce processes. According to the standard regulations, the moisture content of wood cannot exceed 12%. Some unqualified products do not strictly control the raw materials and selection links, resulting in situations such as broken wheels falling off and structural deformation during the use of furniture. In addition, the easiest to ignore is the furniture user manual. Many people will not pay attention to whether there is a user manual when buying furniture. In fact, this is also an essential item for qualified furniture products. The user manual should fully introduce the structure of the furniture, issues to be noted, how to repair, and how to maintain. If there is no user manual or if it is solid and durable, these are the basic requirements for using furniture. Therefore, the strength of drawer slide rails, the material requirements of metal components, the material requirements of wooden components, and the moisture content of wood are all important indicators to ensure the firmness and durability of furniture. When purchasing furniture, you should pull out each piece of furniture with drawers to check whether the slide rails are smooth when the drawers are pushed and pulled, and whether the locks are tight. Industry standards stipulate that if the content of the manual mark is incomplete and cannot guide consumers to correctly use and maintain furniture, it also belongs to unqualified products.
