Wood-fiber boards frequently to denoteabbreviation fiberboard. They represent a compressed mass of cellulose and synthetic fibers, water and various additives conferring special properties of chipboard.
Such plates - one of the most common building and finishing materials.
Wood-fiber plates are made ofWaste wood and paper industry, but at the same time have a number of positive characteristics, which make them popular in the furniture industry, construction, finishing and insulation works, automotive, joinery and different packaging.
Fiberboard - wear-resistant, flexible, durable, lightweight and at the same cheap stuff.
Classification of fiberboard according to the method of production
Fiberboard can be produced by wet or dry method. The wet method involves pre-soaking the material in water. These boards are formed under the influence of small temperature, and then dried. Surfaces MDF wet method of production are different: one mesh, the other smooth.
In the dry blend manufacturing process and materialsadditives fed to the press in a dry form, and in order that the plate has formed, the heat is applied. Hardboard dry process once a smooth surface and a loose structure.
Classification of fiberboard to destination
There are general and special purpose boards. Fiberboard used for special purposes when the material requires any special performance characteristics. Among the plates isolated special purpose:
- Cement-bitumen plate and they have high strength and are used for the construction of walls cement fiberboard is often used when laying polov-
- Bioresistant fiberboard, impregnated with special solutions that protect the material from bacteria, mold, insects
- Nonflammable MDF, which are used for finishing fire risk areas.
Hardboard - a special kind of chipboard with veneered surface.
Classification of fiberboard hardness
An important parameter Fiberboard - hardness. Allocate soft plates, their density is not more than 350 kg / m3 and a density fiberboard solid from 800 kg / m3.
Soft fibreboard manufactured at lowtemperatures, their strength is very small, but they have a porous structure, which gives them a good heat and sound insulation properties. Therefore, these fibreboard used for insulation work in buildings. The most frequent use of them - insulation of roofs. Soft fiberboard may have a thickness of from 9 mm to 25 mm.
Varieties of hard fiberboard very much. They differ in the type of the outer layer - neoblagorozhennye, tinted, with a layer of wood pulp, - as well as the density and hardness. For their classification developed notation. The main performance properties of this type of hardboard - hardness, so they are used mainly in the furniture industry and construction.
