A Comparative Study of the Performance of Wood-Plastic Composites and Typical Substrates as Heating Floor

Abstract

The thermal properties of wood-plastic composites (WPCs) and typical heating floor substrates heated by an electrothermal film were studied. Their effects on human feelings and the human autonomic nerve system were also investigated. The temperature changes of the specimens during heating and cooling were analyzed with an infrared thermal imager. People's subjective feelings of touching different materials were analyzed with a semantic differential (SD) technique, and their electrocardiography was recorded with a multi-channel physiological signal acquisition system. The thermal conductivity, temperature variation, tactile impression, and heart rate variability of WPCs and other heating floor substrates were investigated. The WPCs presented a markedly lower thermal conductivity and superior tactile impression compared with ceramic tile, which has a similar density to WPCs. There was a negative correlation between the scores of the warm-cool feeling and the density of the heating floor substrates under room temperature (19 °C ± 1 °C), and a positive correlation when heated (33 °C ± 1 °C). The thermal conductivity and heat storage capacity of WPC were higher than those of solid wood. Electric heating composite floors with a high comfort level and good thermal properties could be manufactured by combining WPCs and solid wood.

Promoting and Demoting Factors of Ecodesign Methodologies for The Application of Recycled Construction Waste: A Case Study of a Composite Product

“…The CTE was estimated from the respective plastic matrix to be inversely proportionate to the filler amount [36]. Thermal conductivity of recipes 1-3 and recipe 6 was estimated as 0.35-0.36 W/(mK) and for recipes 4-5 0.40 W/(mK) [37][38][39]. Density for recipes 1, 2, 3, and 6 was estimated from their composition; the extruded WPC density is commonly 1.05-1.20 g/cm 3 .…”

“…These natural fiber-containing composites with excellent properties can be used in varied applications. Wood-plastic composites offer especially promising properties (Yi et al 2017;Dun et al 2019). Compared with plastics and wood products, wood-plastic composites have improved thermal properties, physical mechanics, creep performance, and enhanced durability.…”

Stability of Soluble Dialdehyde Cellulose and the Formation of Hollow Microspheres: Optimization and Characterization

“…As a kind of natural polymeric material, cellulose has many advantages, such as its low cost and wide availability, renewability, biodegradability, and biocompatibility, which have garnered sharply increased interest in its potential for the replacement of fossil resource-based materials. − However, the fibrils from various biomass materials (bamboo pulp, wood pulp, cotton linters, tunicates, etc.) exist in the form of aggregation structures and their applications are strictly limited due to the large number of hydroxyl groups in the crystalline regions, which form a large hydrogen bond network and restrict solubility in water or common solvents. , The modification of cellulose, as a major direction for further materials preparation, emerged quickly. − …”
