Fiberboard: what is it, and how is this material used?

In the repair and construction of houses, many materials are used, but there are some among them that have covered themselves with unfading fame. Take, for example, fiberboard. What it is?

The name stands for "fibreboard." This sheet material, which is produced by pressing wood chips with the addition of various types of binding components.

As a rule, synthetic polymer resins are used in the last incarnation. In addition, they include various substances that impart hydrophobicity properties to the finished material.

The most expensive (and therefore more often used) ceresin and paraffin. Often the composition is added antiseptic additives. Because of them, mold does not practically grow on fiberboard. What it is? Most often in the role of such an antiseptic additive are phenols, which successfully hinder the development of fungi and destroy their spores.

Wood-fiber plates are produced in two ways: dry and wet. However, recently there were intermediate methods: wet-dry and semi-dry.

The cheapest method is dry, when the fiberboard (what it is, we have already said) is formed from wood chips in ordinary conditions and without wetting it with water. Pressing of the board is carried out at high temperature and pressure.

The resulting material is characterized by low cost, considerable porosity and lightness. Its moisture content is only 6-8%.

The wet method is in the same stages, but the wood chips are sent to the pressing, being moistened with water. After leaving the press chamber, the material is cut into separate sheets and sent to the dryer. Such panels of fiberboard have humidity already within 70%. Because they are more powerful, but more durable.

The semi-dry method is similar to the first method, which is described above. The only difference is that before feeding to the compact, the chips are watered, so that the moisture content of the resulting material is 16-18%.

The wet-dry method differs from all of the above in that, first, a plate is formed from the water impregnated with water, then it is fed to the drying plant and only then sent to the hot pressing procedure. The result is a fiberboard plywood with a relative humidity of 0%.

Note that we do not act correctly when talking about "shavings". The fact is that this shaving, with the help of special machines, is first triturated into fibers, from which the fabric of finished panels is already formed.

In recent years, a refined fiberboard has been used much more often. When manufacturing such panels, a multi-layer coating is applied to their surface. At the first stage, the plate is covered with a special primer layer, which creates a reliable base. It prints a picture simulating the usual surface of a tree.

Such a plate is practically not afraid of moisture, and also abrasion. To harden the surface in this case, a special lacquer is used.

So we told you about the DVP. What is it, you now know. Because of the cheapness and strength properties of this material, it is often used not only in the furniture industry, but also in the construction industry.
