| Popis: | The moisture content and the variation of he himself are one of the factors that more influence has on the mechanical properties of the wood; thus it is necessary to know the incidence these fluctuations. The hardness, defined as the resistance that presents a wood to the penetration, the dents and to the wearing down; is strongly employee of the moisture content obtained in the drying process; which can be seen affected by the phenomena of sortion and desorption. With the present investigation one evaluated the effect of the equilibrium moisture content was evaluated on the hardness for the species Eucalyptus pellita, Eucalyptus tereticornis, Pinus caribaea and Tectona grandis; taking like indicator the test of hardness, according to COPANT 465. The moistre contents adjusted 12% and by means of correlations the influence of the anatomical constitution settled down on this property. The analysis of the information became through ANAVA of double via. The obtained results showed a superior hardness in desorption withrespect sortion; had to the conditions that affected the wood in the drying partly process which affected a weakening of the anatomical structures and therefore the denaturation of the wood. |
