Semi-hard fiberboard: Also known as medium-density fiberboard, the bulk density is 500~700 kg/m3, which is mainly used for construction and furniture. The decorative Material is commonly used in the middle layer of the composite floor, the core plate of the cabinet door, and the like.
First, what is the fiberboard
The fiberboard is made of wood or vegetable fiber as the main raw material, mechanically separated into monomer fibers, added with additives to make slabs, and combined into a wood-based panel by hot pressing or adhesive. The thickness is mainly 3, 4, 5 mm. Due to the waterproof treatment, the fiberboard is less hygroscopic than wood, and has good shape stability and antibacterial properties.
Second, the classification of fiberboard
1. Classified by raw materials. Fiberboard is divided into wood fiberboard and non-wood fiberboard. Wood fiberboard is made from wood processing waste. The non-wood fiber pattern is made from herbs such as reeds, straw, straw, and bamboo.
2. Classified by processing method.
(1) Extra hard fiberboard. The fiberboard treated with the reinforcing agent or the oil-impregnated fiber has good strength and water resistance and can be used indoors and outdoors.
(2) Ordinary hardboard, without specially treated fiberboard.
3. Classified by volume.
(1) Hard fiberboard: Also known as high density fiberboard. The capacity is greater than 800 kg / cubic meter.
(2) Semi-hard fiberboard: Also known as medium-density fiberboard, the bulk density is 500~700 kg/m3, which is mainly used for construction and furniture. The decorative material is commonly used in the middle layer of the composite floor, the core plate of the cabinet door, and the like.
(3) Soft fiberboard: Also known as low-density fiberboard, the bulk density is less than 400 metric tons/m3.
Generally, the strength of the fiberboard increases as the bulk density increases, and the gas permeability decreases accordingly.
Third, the selection of fiberboard
1. The thickness is even, the surface is smooth and smooth, and there are no stains, water stains or sticking. The surrounding panels are fine, strong and have no burrs.
2. Low moisture content and low hygroscopicity.
3. The surface of the board can be tapped by hand, the sound is crisp and pleasant, and the uniform fiberboard quality is good. If the sound is boring, there may be a problem with the glue.
