Abstract:In this paper , multivariable predictive the thermal conductivity of insulation materials, density, water absorption, permeability coefficient, fire resistance and other performance indicators, often used on rigid polyurethane foam, polyethylene foam, polystyrene foam, centrifugal glass sponge , rubber and foam, and rock some new insulation materials such as cotton were analyzed, and evaluated its application are described.
Pipe insulation technology for a detailed overview of investigation and analysis of performance under the thermal insulation materials, application, selected on the basis, the choice of insulation material thickness of the method of cold air distribution systems and heat pipe insulation material selection methods do a description of that cold air systems and heat pipe insulation to the calculation of rigorous optimization of the thickness of a rational economic choice, to ensure that the system energy. Some insulation materials used by contrast, the selection of insulation materials derived principle.
With the specific engineering, focusing on the rubber insulation materials research and analysis, through comparison with other insulation materials that rubber insulation materials at low temperatures because of its excellent performance is widely used in pipeline projects.
Finally, the external wall insulation and thermal insulation materials, technology, and new plastic heat insulation materials in building energy efficiency on the application and prospects are described.
