[ Chinese wardrobe net ] Because the panel furniture is a wood-based panel, the natural price is not as expensive as solid wood furniture. But there are also many types of panel furniture, such as particleboard, medium fiber density board and so on. Today's consumers tend to be very environmentally friendly, so which of the particleboard and medium fiber density board has a lower formaldehyde content? Which price is more expensive?
Particle board
Particleboard, also known as particle board, is a thin board made of wood scrap as the main raw material, applying glue and additives such as dry mix and hot pressing.
The production process of particleboard includes three steps: raw material preparation; blank preparation; and board making.
The production process can be divided into three major sections: preparation section; mixing, forming and pre-pressing sections; hot-pressing section (hot pressing, edge and sanding).
The surface of the particleboard is flat, the texture is realistic, the weight is uniform, the thickness error is small, the pollution is resistant, the aging resistance, the sound insulation, the heat insulation, the beauty, the paint and the various veneers can be carried out.
Particleboard is mainly used as a partition wall and interior wall decoration board in architectural decoration. In use, it is usually necessary to cover the surface of the particle board with a plastic veneer. The unfinished particleboard is mostly used for the baseboard of the siding, etc., and only serves as a support. Medium-density (750kg/m3) particleboard and high-density (1000kg/m3) particleboard contain considerable amounts of glue, which can be used to make semi-finished architectural trim panels in direct-installable form.
Density fiberboard
Density fiberboard is a kind of artificial board. It uses plant fiber as raw material, shaving, fiber separation, slab forming (mixing resin glue and additive paving), and making cellulose and hemicellulose under hot pressing. A sheet of plastic formed by lignin.
The production process is as follows:
Broken wood - making wood pulp - screening and concentration of slurry - spray glue - forming - dehydration and drying - compression under high temperature and high pressure - inspection - finished product.
Fiberboard is easy to finish. A variety of oily, colloidal paints can be applied to the fiberboard to make it beautiful and durable. The fiberboard itself is a beautiful decorative plate that can be applied to the structural parts that are decorated or need to be insulated. It can also be coated with various kinds of beautiful adhesive tape film and plastic veneer, veneer or light metal sheet. On the surface of the fiberboard.
Hard fiberboard is an excellent substitute for wood. It can be used for indoor floor decoration. It can also be used for interior wall decoration, decoration, making hard fiberboard indoor partition wall, using double bread box method to achieve sound insulation, punching and drilling. Holes, hard fiberboard can also be used as a sound absorbing panel for ceiling construction projects. The density of the medium density board is 450Kg/m3 to 880Kg/m3.
Analysis of the production process and material selection of particleboard and density fiberboard, we can draw the conclusion that the formaldehyde content of MDF is less than that of particleboard, so MDF is more expensive than particleboard.
