Density board, sandwich panels, solid wood particle board What is the difference between the three, which is better!
The so-called solid wood particle board, in fact, is a particleboard production process of the plate, is a particleboard belonging to the homogeneous particleboard. The particle size of the particleboard is called the directional structure of the particleboard. It is a kind of small-diameter wood, wood cutting, wood core, plate skin, branch material and other raw materials through the special equipment processing growth 40mm, 70mm, width 5mm, 20mm, thickness 0.3mm, 0.7 Mm of the flake, the drying, sizing and special equipment will be the surface of the core layer of cross-staggered orientation after pavement, after hot-pressing a wood-based panel. Large sub-homogeneous particleboard will be sliced through the advanced single-channel dryer for drying, the expansion coefficient is small, moisture-proof performance is very good, the implementation of the planing is layered layers of pavement, so its internal internal texture uniform Ordinary particleboard and powder MDF nail force, bending resistance, stability should be strong. Oriented structure Particleboard as a high-grade environmentally friendly substrate is widely used in Europe and the United States furniture manufacturers, the domestic high-end plate furniture market has begun to use a large area of the plate.
Solid wood particles board a little better
Sandwich board ah light weight, fast construction. Environmental protection, green, recyclable
Density plate (English: High Density Board (wood)), also known as fiberboard, is the wood, tree technology and other objects in the water soaked after hot grinding, pavement, hot pressed, is based on wood fiber or other plant fiber Raw materials, urea-formaldehyde resin or other suitable adhesive made of artificial plate. Because of its soft and impact resistance, high strength, uniform pressure after the uniform, but also easy to reprocessing in foreign countries is a good material for the production of furniture, but the disadvantage is poor water resistance. Medium and high density board, is a small diameter wood grinding and grinding in the high temperature and pressure to suppress, is now common, and our standards on the height of the board than the international standard several times lower, so the density board in China The use of quality has yet to be improved.
Sandwich panel products are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, mature molding of the composition of the polymer core insulation. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, you can put an end to the condensation of water vapor. The forming of the outer steel sheet takes into account the structural and strength requirements, and takes into account the appearance, the inner layer is formed into a flat plate to suit various needs.
