Determination of the Thermal Resistance of Pipe Insulation Material from Thermal Conductivity of Flat Insulation Products
New European product standards now include a mandatory requirement for manufacturers to declare the temperature-dependent thermal conductivity for each insulation used in building equipments and industrial installations. For pipe insulation systems, the measurement is usually performed by a standard pipe test method, in which the value on a large temperature range is integrated to reduce temper...
متن کاملBiomass Derived Nitrogen-Doped Highly Porous Carbon Material with a Hierarchical Porous Structure for High-Performance Lithium/Sulfur Batteries
A novel nitrogen doped mesoporous carbon (NMPC) with a hierarchical porous structure is prepared by simple carbonizing the green algae, which is applied as a host material to encapsulate sulfur for lithium/sulfur (Li/S) battery. The NMPC exhibits high pore volume as well as large specific surface area, and thus sulfur content in the S/NMPC composite reaches up to 63 wt %. When tested in a Li/S ...
متن کاملMaterial Concepts and Processing Methods for Electrical Insulation
Epoxy composites are broadly used as an electrical insulation for the high voltage applications since only such materials can fulfill particular mechanical, thermal, and dielectric requirements. However, properties of the final product are strongly dependent on proper manufacturing process with minimized material failures, as too large shrinkage, voids and cracks. Therefore, application of prop...
متن کاملHighly porous S-doped carbons
Porous sulphur-doped carbons have been prepared by using polythiophene (PTh) as carbon precursor and KOH as activating agent. The activation process was carried out under several operating conditions, i. e. a KOH/PTh weight ratio of 2 or 4, and reaction temperatures in the 600-850 oC range. The porous carbons thus obtained exhibit very large apparent surface areas and high pore volumes of up to...
متن کاملHighly porous tracks in fluorapatite
In volatile-rich fluorapatite, which represents 70 % of all fission track age-determinations, tracks produced along the trajectories of fission fragments have been considered to be cylinders of radiation-damaged amorphous material, similar to tracks in other minerals, such as zircon [1]. The atomic-scale structure of unetched fission tracks controls temperature-induced “fading” and finally lead...
