Thermal breakThermal conductivityMechanical propertiesSustainable development of building industry implies increasing usage of green materials. With this aim and for the intended application as a structural thermal break material, rigid high-density polyurethane foams have been manufactured using polyols ...
Methods and systems for forming members from strips of thermally conductive material which have a generally central longitudinal slot are described. The slot is bridged by a material, e.g., a polymer, with low thermal conductivity. This provides a thermal break which inhibits the flow of heat ...
Researchers reported that silk fibre has been used most extensively as sutures for centuries and recognized increasingly as a prospective material for biomedical textiles, because of the availability of large quantities of material from the textile industry, the ease of processing, controllable degradabilit...
thermal break. The enclosed raceway is monolithically constructed with the receiver for the outer raceway element, with a thermal break disposed therebetween. In the depicted embodiment, the thermal break comprises a full separation between the metallic elements. That is, the thermal break material is...
The supernatant with the soluble material was placed in a beaker to dry at 100 °C for 4 h; the tube containing the gelled insoluble material was immediately weighed. The calculations were carried out based on the following equations: WAI (g/g)=Weight of the gel (g)Sample (g)WAI (g/...
of the material are due to the intrinsic organization of its constituents with dielectric relax- ation, which affects the dipole moments present in the material [53]. It can reveal useful Tafel pinofolramraitzioantaiobonutstthue cdhiaerasctweriestricemcoalercruileardaroraungtetmoenotbs.sFeorrv...
Samples from sheets of the polymeric material Bayfol have been exposed to electron beam in the dose range 10-100 kGy. The resultant effect of electron beam irradiation on the thermal properties of Bayfol has been investigated using thermogravimetric analysis. The onset temperature of decomposition T ...
Thus, at lower frequencies the charge carriers may not move and further they will be confined to certain microscopic region of the material. At this moment, the overcrowded nature of charge carriers usually takes place. This implied a fact that all the charge carriers were not able to break ...
Only one clear difference occurs for the strain to break value which decreases by about 30% for wheat-flour based materials. 展开 关键词: Cereal flours Biodegradable material Thermoplastics Extrusion SEM Thermogravimetry DSC X-ray diffraction
