Types of fibreboard

Wood-fiber plates are more commonly calledAbbreviation of fiberboard. They are a pressed mass of cellulosic and synthetic fibers, water and various additives that impart special properties to fiberboard.

Such boards are one of the most common construction and finishing materials.

Wood-fiber plates are made ofWaste wood and paper industry, but at the same time they have a number of positive characteristics that make them in demand in the furniture industry, construction, finishing and insulation work, automotive, production of joinery and various containers.

Fibreboard is wear-resistant, flexible, durable, lightweight and at the same time cheap material.

Classification of fibreboard according to the method of production

Fibreboard can be produced by wet and dry method. A wet method involves pre-soaking the material in water. Such plates are formed under the influence of a low temperature, and then dried. Surfaces of fiberboard wet mode of production are different: one mesh, the other is smooth.

With a dry method of production, a mixture of materials andAdditives are fed to the press in a dry form, and in order for the plate to form, heat is applied. Fibreboard of dry method of production immediately has smooth surfaces and a more loose structure.

Classification of fiberboard by destination

Allocate plates of general and special purpose. Special purpose fiberboard is used when the material requires some special operational properties. Among the special-purpose slabs, there are:

- cement-containing and bituminous slabs, they have high strength and are used for the construction of wall-cement fiberboard often used for laying floors-

- biologically resistant fiberboard, they are impregnated with special solutions that protect the material from bacteria, mold, insect-

- Hard burnable fiberboard, which are used for finishing fire-hazardous premises.

Organites - a special kind of fiberboard with a lined surface.

Classification of hardboard by hardness

An important parameter of fiberboard is hardness. Soft plates are distinguished, their density does not exceed 350 kg / m3, and solid fiberboard with a density of 800 kg / m3.

Soft fiberboard is manufactured at lowTemperatures, their strength is very small, but they have a porous structure that gives them good heat and sound insulation properties. Therefore, such wood-fiber boards are used for insulation work in buildings. The most common use is the insulation of roofs. Soft fiberboard can have a thickness of 9 mm to 25 mm.

There are a lot of hardwood fiber species. They differ in the form of the outer layer - ungraded, tinted, with a layer of wood pulp, - and also in density and hardness. A classification system has been developed for their classification. The main operational property of this type of fiberboard is hardness, therefore they are used mainly in the furniture industry and construction.
