Propriedades físico­mecânicas de Pinus taeda e Corymbia citriodora para utilização em pisos

Abstract

The Pinus wood characterization, have a big importance in the recommendation of how better use it. However, to this wood became a good option in the wooden floors commerce, is indispensable the realization of tests who show real conditions for their use inservice. These tests evidence the day­to­day suffering of the wooden floors, concerning trampling by high­heeled shoes, the drag and also the fall of objects, the resistance of the surface to friction caused when the conduction of objects and people who use it. Exist a big difficulty to choose new woods to floors confection, because of the low knowledge of their values. The present work aimed to evaluate the wood of Pinus taeda. with applications rolling load, of friction, indentation caused by loads applied in small areas, to look if these wood can be employed to the floor fabrications, according with the results that will be obtained and by the comparison made between wood from Eucalyptus citriodora. that is already well used.Parts off wooden floors with the same origin and manufacture were used in Dois Vizinhos – Pr. The results showed that fot the tests that simulate the use of floors in service there was a significant difference between the species,in almost all testes Eucalyptus citriodora stands out whres only in the friction teste the species of Pinus taedais still outstanding in comparison,but it was emphasized that tge wood analyzed can ba used when it comes to wooden floors that it isconcluded according to the physical mechanical results acquired and through comparisons discovered in the literature.
