In the first part of this article we will elucidate what exactly MDF is and what we have to know about its great structure, beside application and great features of this composite material in today’s life!
MDF as we must to know!
MDF as known widely by its abbreviation, is a type of processed wood derived from the term Medium Density Fiberboard. If we want to give a brief explanation of each and every word of this phrase, we must first interpret that it is in the group of fiberboards in terms of wood division. Because the processed board is made of wood fibers, it is called fiberboard. The next two words are actually defined in one sense and talk about the density of wood or the specific gravity of a fiberboard. Since fiberboard is generally divided into three groups in terms of wood density, LDF, MDF and HDF, which have low, medium and high density, respectively. MDF or medium density fiberboard is located in the middle level of this category.
MDF amazing shape structure in details
The MDF production process is in a way that the fibers obtained from soft and hard chips of wood are heated and pressed heavily into a single board. But because wood chips need to be glued together to maintain the integrity of the wood chips, resin and wax have been used to homogenize the wood chips! Since wood fibers are the raw material for the formation of fiberboard, part of different types of wood can be used to produce MDF to achieve different properties.
If we want to know more about the texture that is evident from the cross-section of an MDF, we can imagine something like a chipboard, but with the wood chips that make up a single homogeneous texture and each separately which are not visible to the human eye. Of course, a low-density wood chipboard is weaker than MDF due to its incoherent texture. Substrate boards with a higher density than chipboard are called the general category of fiberboard, as described earlier, and MDF is one of them.
MDF is produced in various thicknesses in thin, medium and thick types and in different board sizes for different applications. Each of these thicknesses has its own standard. Standards have also been set for cutting large pieces in different dimensions of fiberboard boards. In addition, raw and processed varieties of this product are available. The raw type is provided without a simple cover and board, and the processed type is provided with a variety of functional and purely coated coatings. Coatings on MDF are also coated with adhesive, which is finally glued to the raw board under the pressure of the press machine.
MDF application in design and much more!
It is unknown whether the MDF originally built to replace chipboard indeed or not, or whether the original it was made for high-volume paper pulp waste. But the first MDF manufacturer in the 1960s produced so many successful products that MDF production soon began all over the world, eventually turning MDF into an alternative product to other wooden material and it converted nearly all kinds of natural wood and other products.
MDF has almost unlimited uses. The home use of MDF is to provide a variety of furniture, beds, cabinets, doors, tables, parquet and flooring, shelves and cupboards, as well as wall decoration (underlayment) and wall coverings (finishes). In the construction industry, It is also used as a construction material in the size of large boards.
Positive features of MDF or medium density fiberboard
Natural wood has always been available to both builders and the public, and has been very popular, original, and high-quality, but with the advent of environmental issues and the deteriorating health of the planet, more attention has been paid to alternatives. Even if product alternatives had been invented before that time. In contrast, MDF is an environmentally friendly green product because it is made from recycled materials. Of course, the recyclability of raw materials does not mean that the quality of work has decreased. MDF was made from the same materials and wood waste from the very beginning of production and became very popular from the very beginning of production.
Due to the materials used, there is naturally no knot on the MDF surface. This makes it easier to cut, machining, drilling and sanding. Also, by paying the MDF procedure, a smooth level is created. These two issues make the MDF color and coating look good. One of the great advantages of MDF is its variety.
A variety of industrial materials are also used to cover MDF for special purposes such as antifungal, anti-moisture, waterproof, scratch-resistant, fire-retardant and the like. For example, This alone can swell and swell if it comes in contact with water, but it can be prevented by a waterproof coating.
In part 2 of this article we will go over other great advantages and application of MDF beside catching up the disadvantages!
