MDF: what is it? How to choose the building material

When selecting construction materials should always be informed about the quality, scope, reliability and durability for the desired scope of use. One of the most popular products of wood fiberboard is, the scope of which is quite extensive. MDF: what it is and how to choose the right stuff to get a reliable product with a long lifetime, is described in detail in this article.

MDF: what it is

hardboard - a building material, which is made of wood fibers with the addition of additives and the binder adhesive hydrophobizing chemicals components ( "wet method"), or without the application ( "dry method"), a method of pressing and drying of pulp, which is formed in the form of rectangular carpet.

The starting material manufacturers use sawmill waste, wood, plant combustion. The coarse raw materials by steaming and grinding defibrator processed into the necessary fibers. As the binder component of the synthetic resin used in an amount of 4-7% of the ratio of the fibers of hardwood and softwood.

To improve the water resistance in the wallboard material mass introduced paraffin, ceresin or rosin.

Fiberboard production is one of the most promising methods of use of wood waste. This material is widely used in a modern house-building to achieve thermal and acoustic insulation of walls and floors premises, the manufacture of intermediate floors, finishing the internal components of premises, furniture manufacturing and packaging containers.

The history of occurrence of fiberboards

In 1858, the first scientist Limon patented his discovery. Later, the scientist Myunhon perfected the technology of manufacturing fiberboard. He proposed to use the equipment for hot pressing. At this stage in the manufacture of binder material is not used ingredients.

And already in 1924, the American scientist Mason offered a modern method for fabricating fiberboard using a "wet process" in which the final material possessed high density.
Technology of production of hardboard

MDF is made on the basis of the flow chart, the structure of which remains unchanged for more than fifty years. This process consists of several stages:

1. pulp washing. From it mechanically in absorbent installations removed sand and other debris.
2. Removal of metals from the mixture by electromagnets on special separator units.
3. Chopping wood chips. Here you can set the degree of grinding, from coarse to finer.
4. In defibrillyatornoy installation in the total weight is mixed polymers, resins, and paraffin.

Further manufacturing fiberboard is produced by "dry" or "wet" method. The "wet method" is more ecological, because there is involved a small dose of the binding mixture, which is toxic. Density Fiberboard and technical indicators are directly dependent on the manufacturing process.

Varieties fiberboard: Photo examples

Depending on the material properties, method of manufacture and a method of further applying modern industry produces the following types of wood-fiber plates: soft, medium-density, semi-solid, solid, superhard. you can buy fiberboard in any hardware store. Price per page is determined by the size and appearance of the product.

soft fiberboard

Soft fiberboard is characterized by low strength, high porosity and low thermal conductivity. The thickness of the slabs varies between 8-25 mm. density index is between 150 and 350 kg / m³. Based on the density of the material, there are marks plates: M-1, M-2 and M-3.

This type of fiberboard is not used as the primary building material. It can be used for heat and sound insulation of building structures, such as walls, floors, ceilings, etc. This is analogous to the drywall, but more lightweight, elastic and easy for installation. Buy soft fiberboard can be substantially cheaper than corresponding plasterboard sheet size.

Plates may also be used as an underlying layer for parquet, linoleum or laminate. Fiberboard is also used for alignment defects base when laying floors.
Useful advice! In the manufacture of soft fiberboard not use synthetic binding element. It speaks about the environmental safety of this material, which can be used for finishing the kids' rooms and allergy sufferers.

Fiberboard semisolid

In comparison to soft type, this type of fiberboard has a high strength and density indicators. The average density fiberboard panels is 850 kg / m³. The thickness of the sheet can be kept within the range 6-12 mm.

This type of fiberboard is used as the rear walls of furniture, shelves, drawer cabinets and tables. It is also frequently used as substrates for mounting floors. He gained popularity as an application as a packaging material.

solid fiberboard

Indicator solid density fiberboard is in the range 800-1000 kg / m³. Product thickness - 2.5-6 mm. These plates are used in the manufacture of furniture as the rear wall, drawers and for the production of panel doors.

Useful advice! The front surface of ennobled fiberboard solid melamine and synthetic films. With a glossy, opaque, pigmented and mimic the texture of wood, plates can be used for covering inner walls of premises.

In turn, this type of plates depending on the strength, density and type of the front side is divided into several grades:

• T - plate with a refined face;
• T C - the front surface is made of a mixture of fine wood;
• T-B - Plate with neoblagorozhennoy face, and an increased rate of water resistance;
• T SW - a plate from the front surface of the fine weight and a higher degree of water resistance;
• T P - tinted front plate side;
• T-PO - facing layer made from fine mass tinted;
• HT - plate with low density.

Very popular white fiberboard. Such a universal color of the material can be used to create bedrooms, kitchens and children's rooms. Such a coating may be decorated with special paint, followed by application of the clearcoat. Buy white fiberboard can be at a lower price than the same list in any other color.

Fibreboard refined face

Humanized fiberboard have high resistance to moisture and mechanical abrasion. Due to the unique manufacturing techniques, they have an attractive appearance. During manufacture of this type of plates used technology of applying a multilayer coating to the front surface. Plate is processed and then applied to the surface thereof a primer layer which is a background basis for future picture. The pattern may be different. But each species in its own way is an imitation of the wood structure.

Such plates are used for the manufacture of door panels for walls and ceilings, internal furniture elements. Modern industry produces made of fiberboard doors in standard sizes.

superhard fiberboard

These plates have a high density index, which is 950 kg / m³. This high-quality material, which is convenient and easy to install. The high strength of the plate is achieved by impregnating pectolite. These superhard fiberboard used to make walls, arches and doors. Also widely used in the manufacture of floor coverings. A high rate allows the use of insulation plates for the manufacture of panels and flaps.

MDF

MDF or MDF plate is a kind of a semi-solid. This is a relatively new building material, which took pride of place at furniture makers and builders. This is because a density of 700-800 kg / m³, strength equal magnitude as in hard fiberboard, which is almost twice higher as compared with particleboard.

Due to the ease of processing, MDF is widely used in the modern construction industry. Of the plates are made architraves, skirting boards, fillets, facades of furniture, window sills, roof battens, T-bars. Their use in the production of interior door panels. A ceiling and wall panels Fiberboard this category will be elegant solution for indoor decoration. MDF also manufactured laminate.

Given an important question, how much is fiberboard, it is important to define the area for its further application. Here it is necessary to take into account all the characteristics of each type and choose the best, based on the price and quality.

Laminated MDF: a complete solution for finishing

Most popular today is the use of laminated chipboard. Material is deposited on a special mixture which consists of certain synthetic resins. Thanks to such technology, these plates have an increased moisture resistance and durability.

In DIY stores you can buy laminated fiberboard following varieties:

1. Tiled type. This brand fiberboard has a wide range of sizes from 30x30 cm and ending with 100x100 cm. Such plates are attached via tongue and groove connections with special klyaymerov or staples. Using plates allows forming interesting patterns and ornaments. Every year the industry produces fiberboard with a new color scheme and textured patterns.
2. Fiberboard under the bunk. This is a new and more modern format material. By its method of connecting it is similar to a wooden paneling. This sheet material has standard dimensions. Compound of sheets is the same as fiberboard tile type. Such a fiberboard is used for blouses surface walls and flooring. The material has a high degree of moisture resistance.
3. Leaf type. It is a versatile type of laminated chipboard. It has a lot of options of textures, colors, sizes and ways of fixing material on the ceiling, the floor, the walls.

Applications laminated fiberboard

The laminated fiberboard has certain properties, which are considered when selecting it for further use. Due to the high index of sound insulation, such plates are used for the premises where necessary to achieve maximum isolation. This applies to broadcasting cameras, sound recording studios.
