The density of wood, the characteristics of this material and its features

The ratio to the volume of wood mass - this is how the density of the tree is calculated , no matter what kind of breed it is. Kg / m3 - this is how this characteristic is expressed and denoted. In each individual breed, the density depends on the substances that determine the cell. In addition, a mass of wood substance in a unit of volume becomes an important parameter. This property is largely determined by the fact that each breed has its own density.

What else do you need to know about density?

When the density is calculated for a particular breed, it is said about the mean or conditional characteristic. In the case of a conditional one, one speaks of the relation to the volume of the mass, but the volume of the cellular cavities is not taken into account. And the wood itself is estimated in absolutely dry condition.

For all types of wood, the main substance consists of approximately the same components. Counting the density of the tree , this must be constantly remembered. That is why in all breeds this conditional characteristic has about the same value. This figure is 1.56 g / m ² . At a humidity of 12 percent, all the parameters of the physical and mechanical properties are determined. The density of the tree is related to strength. This characteristic can also strongly depend on humidity. There are special tables in order to study the characteristics of a particular breed.

What about the average density?

The porosity of wood and moisture are the main indicators that determine this parameter. Usually the value is indicated in relation to humidity of 15 percent.

Why is it important to know this characteristic?

In practice, the density of the tree is really important. For example, harder and harder will be wood, which has more. This means that the material will be more difficult to handle. Antiseptic wood with higher density is also treated worse than other options.

This parameter serves as the basis for the classification, according to which existing rocks can be divided into three groups. For example, trees with low density. From coniferous species to this group include all species of fir and spruce, pine, all kinds of cedar, ordinary juniper. If we talk about hardwoods, then mention is velvet Amur, Manchurian, gray and white walnut, sowing chestnut, black and white alder, aspen, all kinds of willow, lime and poplar.

What other types of trees exist?

The average indicator in this direction are figures from 560 to 750. Among coniferous species, yew and larch belong to this species. But there are much more representatives of deciduous species. For example, Manchu and common ash, apple, persimmon, mountain ash, platanus, walnut, hazel, maple, karagach, elm, Mongolian, marsh, eastern and summer oak, pear, elm, European and oriental beech, black and yellow, Warty birch. These are rocks that have almost the same density of wood. The table will help to understand the features of this parameter, it is enough to find the right material.

Figures from 750 and above are not so common, but you can still find such trees. For example, pistachio and boxwood. Or hornbeam. The density of tree species in this group is really surprising, but most of these plants practically do not occur in our country.
