It should be emphasized that the present authors studied samples with greater variation in density (0.4, 0.5, and 0.6 g/cm) compared to the work in question, besides the nature of the inputs to allow a reduction of porosity, such as the use of the cement bag. 696-713.DOI: 10.1002/9780470209707. Director -Yatao Li. The more highly porous panels were more acoustically efficient, with a sound absorption coefficient close to 0.8 at 3.2 kHz, and they had a better thermal conductivity performance.The potential of these panels for application where sound absorption and thermal insulation are prioritized is thus observed. The panels were consolidated by hot pressing for 10 min at 100 C. The Fireside Lounge, located in the SAU / Campus Center, is a multi-purpose lounge and event space. In insulation materials, heat transfer occurs in the material and voids filled with air.

Even though they presented different densities (590 kg/m and 550 kg/m) and levels ofporosity (55.7% and 53.6%), these property variations were not substantial enough to affect the thermal performance of the panels. Oliveira, P. D. P. S. (2009). If you have any questions or inquiries about Tech Crew services, contact us at (585) 475-2257 or tecccl@rit.edu. This scenario was reflected in the increase in the consumption of wood panels, with the country having the first importation in a large amount of product (Roque and Valena 1998). Retail. The heating rate was 1 C/min. Table 2 shows that the variations in the pressing pressure of the panels affected the property of thickness swelling, at 2h and 24h, as demonstrated by an increase in the swelling associated with the increase in the porosity of the panels. (2018) analyzed the sound absorption performance of natural kenaf fibers in a reverberant chamber.

(2016) investigated the adaptability of paper sludge with wood fiber in cement-based insulation mortar by means of thermal conductivity. The development of materials that offer environmental comfort inside buildings, through adequate thermal and acoustic behavior, has been as relevant as the search for raw materials of renewable origin. 3. (2012), the thermal conductivity is directly related to the density of the insulation panels: higher density leads to higher thermal conductivity. Software that considers the registered temperatures and the sample size was used to obtain the thermal conductivity. (2013), the following was used for the production of the panels: adhesive contents of 12% (relative to wood particles weight), considering a ratio of polyol to prepolymer of 1: 1. The panel porosity was investigated by scanning electron microscopy (SEM) and mercury intrusion porosimetry techniques. Sound requirements and advanced lighting needs in this space are supplemented by our professional equipment which is brought in to meet the needs of your event.

According to Berardi and Naldi (2017), the temperature and the moisture content are influential relative to the conductivity. In this method, the sample is placed in a cavity insulated by a refractory material, whose bottom is heated using a temperature-controlled oven. Compared with previously reported products of the same nature (Table 4), the panels of this work obtained close values of thermal conductivity. Samples with a higher pressing pressure (4 MPa) during the manufacturing presented lower thickness swelling and higher mechanical properties in static bending. Privacy Statement. LandAcknowledgment. It should be noted that mechanical strength is not one of the main requirements in thermoacoustic products.

The Symposium is organized by Dr. Elena Sommers (Department of English). Thermal insulation materials can prevent heat loss and provide thermal comfort. In view of the properties analyzed, the panels produced with a lower press pressure of 2.5 MPa have better characteristics for use in thermoacoustic products. The panels of 2.5 MPa, i.e., of higher porosity, were more acoustically efficient, with asound absorption coefficient close to 0.8 at 3.2 kHz. To evaluate the influence of panel porosity on their thermal and acoustic properties, this study produced and characterized panels made withPinussp.
