At present, as for furniture, doors and windows, in addition to solid wood, another interior decoration material which is widely used is the laminated mdf board. Laminated mdf boardis loved by manufacturers and users because of its excellent physical and mechanical properties, decorative properties and processing properties. At the same time, laminated mdf boardis also an effective way to comprehensive utilization and rational utilization of wood, so as to reduce deforestation and protect the ecological environment. However, because some users do not know the raw material very well, there are some misunderstandings and even some people equate it with cardboard. Here, let’s learn about laminated mdf boardmore clearly.
First of all, laminated mdf boardis a kind of artificial plate made from small diameter log, which will experience the following processes: cutting, processing residue and plant fiber after slicing, cooking, fiber separation, drying with resin or other suitable adhesive, and then hot pressing. The laminated mdf boardis divided into three categories by its density. Those with a density of less than 450 kg / m3 are called low densitylaminated mdf board. The density is between 500 kg / m3 and the thickness is 2 × 30 mm is called medium density laminated mdf board. Those with a density of more than 800 kg / m3 are called rigid laminated mdf board. Laminated mdf boardis mainly used in the production of finished furniture, but also used to strengthen wood floor, door board, partition wall and so on.
Second of all, the fiber structure of laminated mdf boardis uniform and the bonding strength between fibers is high, so its static bending strength, plane tensile strength, elastic modulus and other properties are better than those of particle board. Because the surface of laminated mdf boardis smooth, it is convenient for adhesive veneer materials such as thin wood and thin page paper, and it is convenient for finishing and saving paint. laminated mdf boardcan be produced into plates from several millimeters to tens of millimeters thick, so it can replace arbitrary thickness of wood, square wood. At the same time, it also has good machining properties, such as sawing, drilling, slotting, tenon, sanding and engraving. The edge of the plate can be machined according to any shape, and the surface is smooth after machining. Its heat insulation and heat preservation performance are good and will not get aged. Its adhesion is strong, and the hard density plate can also be made into sound insulation and sound absorption board after blanking and drilling, which can be used in the decoration engineering of buildings. Due to the above excellent characteristics, it is used in high-grade furniture manufacturing, interior decoration, audio shell, musical instruments, car and ship decoration, construction and other industries.
The last but not the least, because the laminated mdf boardis made of fiber and its structure is very uniform, it has strong compressive ability and is not easy to crack, deform and bend. However, the moisture resistance of laminated mdf boardis poor, and the expansion coefficient is larger after absorbing moisture. Because the strength of laminated mdf boardis not high, the height of furniture should not be too high. The inner part of the laminated mdf boardis powdered, so its nail grip is poor.
