At present, the furniture materials are mainly wood-based panels and solid wood, and there are many kinds of wood-based panels. Particleboard, that is, solid wood particle board and density board, its core component is urea formaldehyde glue, and its content is very high. The curing effect of low content is poor, resulting in insufficient strength and nail grasping force, and uric acid glue is the main source of formaldehyde, so particleboard and density board can not be directly used naked, Particleboard, particle board and density board are only the base materials of plates. They are used as furniture plates to solve this problem. The finished cabinets of industrial chemical plants mainly soak the large surface of veneer paper hot pressed plate base materials through melamine hot solution, and then seal the four sides of the facade through plastic PVC edge sealing, so as to seal the whole base materials with high formaldehyde emission and solve the pollution problem.

Furniture is three-dimensional, so it involves the connection and assembly of multi-dimensional planes. It has to be assembled through hardware, and the sealed substrate has to be perforated to fix the hardware. The formaldehyde in uric acid glue continues to volatilize through the later holes and cuts, and this time is more than ten years. Therefore, if the edge sealing process is good, the edges are not opened, the holes and cuts are small, and the formaldehyde emission can be controlled, If it is similar to the on-site cabinet, edge sealing and opening, it is not as good as the advanced equipment and processing technology of the factory, so it is better to buy the factory.

Solid wood is natural and formaldehyde free. Some wood has its own natural flavor, and most of them have no flavor. However, the processing technology of solid wood is dominated by panel mortise and tenon. Panel glue needs to be used in panel production and tenon connection. White furniture needs painting, wood wax oil, water-based paint and other coatings. The formaldehyde source of solid wood furniture is joinery glue and later coating materials, The joinery glue, including panel glue and white latex, is a water-based environmental protection glue. Its formaldehyde content is very low. More importantly, the glue is only used at the splicing of solid wood furniture, and the splicing surface of panel is a very small area. Even if tens of grams of glue is squeezed out by the clamping force of the fixture, it is finally thrown away as the waste in the glue removal process, Finally, the residue on the furniture is very small, which can be directly ignored.

The painting problems of solid wood furniture are mainly oily paint, water-based paint, wood wax oil and oily paint, which have good sealing performance, thick and wear-resistant paint film, can color mix and cover the color difference of wood defects, and can be sprayed in batches. However, thinner such as tiannashui is required for the construction of oily paint, which contains high formaldehyde and benzene release, so the formaldehyde of solid wood furniture mainly comes from the painted surface, Not wood and glue.

After knowing the formaldehyde source of furniture, you can compare the purchase of finished cabinets or customized cabinets from your own needs and actual situation, because now the customization of solid wood furniture is also very popular. Cheap finished furniture is basically cabinets made of particleboard melamine facing paper. Therefore, whether customized or purchased, it must be based on the premise of environmental protection of materials and coating, In this way, there can be less or almost no formaldehyde!
