With economic development, more and more people are finding the practical need to move into spacious, bright homes. However, the health risks of leukemia and other diseases induced by excessive levels of harmful substances such as formaldehyde in substandard decoration materials cast a shadow over the joy of moving into a new home. So, as consumers, how can we identify the types of board materials used during renovations and minimize the health risks associated with improper board selection? Today, we will discuss several commonly used types of decoration board materials and their formaldehyde content.
1. Density board
Fiberboard, also known as density board (MDF), has the highest formaldehyde content. This is because fiberboard is manufactured by grinding wood or plant fibers into a powder, then mixing and compacting the powder with glue. Since the amount of adhesive used is the highest, this results in the highest formaldehyde content. If this type of fiberboard is used in interior decoration, formaldehyde levels can easily exceed standards. Fiberboard is commonly used for indoor partitions and wardrobes, so consumers are advised to avoid fiberboard when choosing furniture.
2. Particleboard
The second highest formaldehyde content is found in particle board, also known as chipboard. Particleboard is made from small pieces of wood fiber, which are then heated and pressurized with glue to create a man-made board. While not made from wood fiber powder like fiberboard, the wood particles are held together by a large amount of glue. If unscrupulous vendors use inferior glue, safety is completely compromised. This type of particle board is also often used to make furniture cabinets.
3. Multilayer board
The third highest formaldehyde-producing material is multi-layer wood. As the name suggests, this type of wood is made by gluing together layers of thin wood veneers. The amount of glue required is considerable, making it less environmentally friendly. It's also commonly used in furniture cabinets.
4. Core board
Ranked fourth in formaldehyde content is blockboard, also known as large core board. This type of board is typically made by gluing two pieces of solid wood veneer together. This type of board typically uses a large core of wood strips glued together, using less glue than the aforementioned boards, making it more environmentally friendly. Blockboard, due to its high solid wood content, offers better workability and is a common choice among carpenters. It is widely used in furniture, door panels, radiator covers, curtain boxes, and other applications.
5. Finger-jointed board
Finger-jointed boards rank fifth in formaldehyde content. Finger-jointed boards bond the wood pieces together like fingers, resulting in a smaller adhesive surface and eliminating the need for large amounts of glue, offering a degree of environmental protection. Among well-known decorative materials, finger-jointed, paint-free, solid cedar finger-jointed boards contain less formaldehyde than any of the aforementioned boards. Furthermore, their core is typically made of solid cedar wood, with veneer wrappings on both sides. While maintaining the natural color of real wood, they also offer greater strength than solid wood, excellent workability, and a lower price than solid wood. These advantages have made finger-jointed boards a mainstream environmentally friendly board. They can be found in a variety of high-end furniture and sliding doors.
6. Solid wood board
Solid wood has the lowest formaldehyde content. However, with the shrinking of forest resources and the need for environmental protection, using a whole piece of solid wood to make furniture has become a luxury.
I believe that in the near future, with the advancement of materials science, humans may completely get rid of their dependence on natural trees, and a material that is both environmentally friendly and durable will completely replace natural wood. This day should not be too far away from us.
