External wall insulation technology and energysaving materials Zhangchuanzhou Dartmouth College Abstract: This paper used on the exterior of our current technology and energysaving insulation material to be addressed. Vigorously promoting external insulation technology, new energysaving materials to strengthen the development and use of energysaving construction so that really to be implemented. Key words: energysaving building； materials The implementation of building energy conservation and environmental protection and energy conservation policy and the main contents of the national economy and implementing sustainable development is an important ponent part. In such a series of energy conservation policies, regulations, standards and mandatory provisions under the guidance of China39。s energysaving housing construction work has been constantly deepened, energy conservation standards continuously, and the introduction of development, many new energysaving technologies and materials, and in residential buildings to promote use. However, China39。s current level of building energy conservation, but also much lower than the developed countries, China39。s energy consumption per unit area construction climate is similar to the developed countries, three times to five times. Cold in the north building heating energy consumption accounts for the local society more than 20% of energy consumption, and the vast majority are used in thermal power generation and coalfired boilers, at the same time to cause serious environmental pollution. Therefore, the construction of this century, China39。s energysaving construction is an important topic. In the construction of the external structure for the heat loss larger, external retaining structure in the wall and make up a large share. Therefore, the reform and building wall wall is the development of energysaving technologies building energysaving technology one of the most important part of the external wall insulation technology and the development of energysaving construction materials is the main energysaving mode. external wall insulation technology 濟南大學(xué)畢業(yè)設(shè)計 外文資料 翻譯 1 Energysaving insulation wall construction techniques can be divided into external walls, insulation and Exterior Insulation two categories. insulation technology and its features External wall insulation in construction, in the internal and external structure to the insulation layer. Construction of insulation fast, convenient operation flexible and can ensure the construction progress. Application of thermal insulation within a longer time, mature technology, construction techniques and testing standards are relatively sound. In 2020 the external wall insulation in construction, about 90 percent of the engineering applications, insulation technology. Been in the area to promote the insulation technology: Enhanced gypsum posite polystyrene insulation board, polymer mortar posite polystyrene insulation board, reinforced cement posite polystyrene insulation board, the Interior paste polystyrene board clean wall plaster and polystyrene particles floor insulation Mortar and cracking slurry pressure Network Haile practice. However, the use of thermal insulation will be more occupied area, thermal bridge is no easy solution, making it easy to crack, but will also affect the construction speed, the second decoration of the affected residents, and the hoisting of the interior walls and fixed objects can easily damage the insulation structure. Insulation within the technical unreasonable, i
