Experimental Study Of New Self-insulation Of Lightweight Composite Panels

Eain factor to maintain human civilization, so both energy conservation and environnergy is themmental protection has become a worldwide subject. According to the study, building energyconsumption accounts for about28%of the energy consumption of the whole society, while the outerwall of building energy consumption is from20%to30%. Therefor, researching new thermal insulationenclosure system is one of methods to deal with the problem of building energy consumption. In thispaper, one proposes light Self-insulation compound wall board, which composes of ceramist concreteand uses polystyrene board to Insulation sandwich. To make light Self-insulation compound wall boardand polystyrene board work as a whole, both boards is connect with high polymer plastic fiber, whichensure the wallboard excellent mechanical properties as well as good thermal performance.The innovation of this paper are to select a custom insulation system as the research object andselect excellent polystyrene board and ceramist concrete which posses insulation and load-bearingproperties as the main material of concrete wall panels. Besides, basing on the combination of theoreticalanalysis and simulation experiment, the paper provides one effective method to diminish the energyconsumption resulted from Heat Bridge effect. Meanwhile, the ANSYS finite element analysis softwareis used to model and analysis, which prove the consistency of the analysis results and the value andsignificance of this new application of the insulation panels.This paper focuses on the thermal and mechanical properties of thermal insulation composite wall,whose main load-bearing material is the ceramic concrete and whose properties including light weight,high strength and thermal insulation are firstly discussed. Using two methods solve the elastic modulusof ceramist concrete in the level of certain intensity, as well as deeply analyzing the influence of fly ashon its permeability resistance. To research the thermal performance of the Lightweight insulationcomposite wall panel, one calculates the heat transfer coefficient with two theoretical methods. This heattransfer coefficient is much smaller than one compared with the self-insulation panels composed ofcellular concrete, which theoretically proves the superiority of performance of self-insulation wall.Besides, one analyzes the connection of temperature distribution and thickness of the insulation sandwich under steady-state temperature of different sides of wallboard through the thermal performance test. Atthe same time, basing on test data, one draws the temperature field simulation graphics and introducesthe concept of temperature field tangent factor, which ensure the size of the heat insulation sandwichlayer under certain wall thickness. Through the comparison of the heat transfer coefficient of theoreticalcalculation value and experimental value, one gets the reason of small deviation. In the last, the analysisrealized with finite element simulation software directs that it is fully consistent with the range ofallowable error that the output graphical chart of the temperature field is compared with the one in thecreated by the experimental data. To study the mechanical properties of lightweight self-insulationcomposite wall panel, one conducts analysis to level of stress by the axial compression ratio and axialcompression ratio, which is realized by using the way to control the loading time. One describes thefailure modes wallboard, wallboard displacement curves and load-displacement curve under the loadingprocess, and measure ultimate bearing capacity with certain the thickness dimension.Based on the above analysis results, the insulation properties of the lightweight insulation compositewall panel meet the relevant national norms which request Envelope energy of not less than65%energyefficiency standards and necessary mechanical properties. What is more, one confirms its feasibility inpractical engineering applications.
