Research & Application Of Function Energy-efficient Decorative Plate

At present, the building energy conservation is thought to be the most direct effective way in energy conservation, the most effective actions to alleviate the energy tensity, to solve the contradictory between the socio-economic development and energy insufficient supply. Relative to other construction energy conservation technology, the superiority of EIFS is obvious: it can avoid producing the building hot bridge, avoid the wall surface winter condensation, benefit to protect main structure body, reduce the destructive effect temperature stress to the structure greatly, and increase the structure life. On the base of the EIFS technology, the heat preservation decoration integration system union the merit of prefabrication class plate, adopts the product prefabrication form in the factory, is make for controlling product quality; Has the characteristic of construction assembly and work efficiency higher.FP means a prefabrication plat has the functions such as decorative,anti-crack,heat-preservation which are demanded in EIFS. The thesis proposes the elementary design theory of the FP structural and the method how to realize them, carries on the FP function energy-conservation level material design and the rationale application research according to 3 energy conservation ideas, prepares the function protector material; establishes the FP process line, and set down the FP system construction craft initially.The structural design and the fundamental research of the FP according to function gradient compound principle: As a new kind of heat preservation-insulation plate, FP is also requested to satisfy following characteristic: 1) Heat preservation-insulation ability is better than traditional heat preservation-insulation material; 2) The security is higher than the traditional EIFS; 3) Waterproof resistance is higher than the traditional EIFS; 4) Construction, maintenance cost reduction; 5) Has safely, independent high-geared operation method. The result indicate: When the outside heat preservation on the same exposed wall has been carried out, on the basis of not increasing general thickness of exposed wall, the Km of FP system diminished above 8% compared to the EPS exposed wall heat preservation system, its heat preservation performance superiority to the EPS exposed wall heat preservation system.FP function energy-conservation layer material design and research: According to 3 layer energy-conservation ideas, using the heat-reflection facing material to reduce the outside heat load on the one hand; on the other hand, carrying on the modification to the heat preservation thermal insulation material, then the thermal conductivity reduces 15-25% , the heat preservation heat insulation performance enhances greatly, and the mechanical properties enhance a density rank, increases the security; finally using PCM has a big calorific capacity to deposit the quantity of heat, thus achieves the overall energy consumption minimizing. Using the wate-released material and polymer as the major function component to prepared FP board protector material, in order to solve the dehiscence and work related question. The research indicated: 1) The emulsion powder mixes the quantity controlled at 1.5% to be possible to improve the mortar crack resistance function; 2) KHG-1 mixes the quantity controlled at 2% to be possible to enhance the cement mortar thixotropy and increase the mortar stability; 3) Carry the performance test on the mortar with different type MC, the results show that mixes the quantity control to be best at 0.1%HPMC to the mortar operating performance adjustment.FP unique technique of production and FP system construction craft introduction: Unifying the technological design during the material preparation process and the performance optimization design during the project application, in order to formulate the unique technological parameter and the technical schedule. Confecting FP special-purpose caking mortar,pointing medicinal preparation material and so on. Proposing a special stick and anchor form of FP which benefit to guarantee system's security.
