Related person in charge of the provincial furniture quality inspection station introduced that the rising rate of qualified furniture year by year shows that the quality of furniture is getting better and better, but there are still some unqualified products existing in the market. Whether furniture is environmental-friendly or not is what people concern most about. Its environmental protection index is reflected as formaldehyde emission volume. Unqualified emission means that the detected value is larger than the standard stipulated value, which shows that enterprises don't strictly control the purchasing and using of major raw materials man-made boards, and the quality of adhesive used during the production process doesn't pass the standard or it is overused. Furniture with formaldehyde exceeding the standard is the "culprit" of indoor air pollution and endangering human health. At present, problems existing in furniture quality mainly reflect in the following seven aspects: the unqualified formaldehyde emission volume, man-made board sealing edge, metal components material requirements, wooden components material requirements, wood water content, drawer slide path strength, furniture instruction items. These problems directly reflect various non-standard phenomena in furniture enterprise production. Besides environmental protection, furniture making technology is also a key factor to guarantee quality. In panel furniture, panel sealing edge is the focus to see furniture quality. Some furniture door panels or box bodies' sealing edges are extremely easy to fall off, and even worse, the exposed edges of furniture panels are not sealed, or the panels inside the box are not processed for sealing edges. This is the result of some small factories with non-standard production reducing costs by saving materials and reducing processes. Regulations stipulate that wood water content cannot exceed 12%. Some unqualified products don't strictly control raw materials and selecting materials links, resulting in situations like broken and fallen-off pulleys, structural deformation etc. when furniture is used. Moreover, the most easily neglected is furniture instructions. Many people will not notice whether there are instructions when buying furniture. In fact this is also an essential thing for qualified furniture products. Instructions should comprehensively introduce furniture structure, problems to be noticed, how to repair, how to maintain etc. If there is no user manual or it is sturdy and durable, this is the basic requirement of furniture use. Therefore, the drawer slide path strength, metal components material requirements, wooden components material requirements, wood water content projects are all important indicators to ensure sturdiness and durability. When buying furniture, you should pull out the furniture with drawers one by one to check whether the slide path is smooth when the drawer is pushed and pulled, whether the lock is tight; industry regulations specify that if the content marked on the instruction manual is incomplete and cannot guide consumers to correctly use and maintain furniture, it also belongs to unqualified products.
