My datasets - Sugarcane bagasse particleboards
Description
The feasibility of use sugarcane bagasse (residue) as an alternative source to wood for the manufacture of particleboard. The data set shows the behavior of the panels against the physical, mechanical and density profile tests required to evaluate the performance of bonded sheets. Three experimental panels were produced for each treatment. From each panel samples were taken which were tested and the mean values obtained in each assay were subjected to statistical analysis. Apparent density: Measurements were made with a digital caliper. This property was calculated from the relation between mass and volume of samples. Moisture content: obtained by the relation between the mass obtained after the climatization of the panels and the dry mass, obtained in an oven. A precision scale was used to weigh the samples. Water absorption and thickness swelling: Initially the samples were weighed in an analytical balance and immersed in water at a temperature of 20 °C for 2 hours, after which were weighed again and after that phase the same procedure was repeated for 22 hours of immersion, totaling 24 hours. The calculation was based on initial mass and fine mass at times and the data were multiplied by 100. The same samples were used for the swelling test in thickness. However, the values obtained were based on initial thickness and final thickness after both periods of immersion in water. Non-recoverable thickness swelling: The same specimens from the swelling tests were used and the calculation was performed based on the initial thickness of the specimens and thickness after air conditioning of the samples multiplied by 100. A micrometer was used for measurement. Surface resistance to screw pulling (SSP), top resistance to screw pulling (TSP): Screws were used for this test that were inserted into the face and top of the panels. A drill was used for insertion of the screw into the samples. The samples were assayed in a universal machine. Internal bonding: "Hot Melt" type adhesive was distributed on the surface of each sample intended for the internal bonding test. The calculation of the internal bond strength was obtained by the ratio of the breaking load (kgf) applied by the universal machine to the surface area of the specimen in cm2. Static bending: The samples were fitted on the test equipment supported on two supports in the universal testing machine. The data acquired in the tests are interpreted based on the values stipulated by the Brazilian standard. Density profile: For the analysis of the density profile graph, 02 specific mass parameters were established: outer layer and central layer.
