GPES保温板体系的热应力作用

来源:http://www.sdyingxu.com/news/19.html 发布时间:2017-03-07

耐候性试验与实际工程有着密切的相关性,能很好地反映高性能保温板外墙防火保温体系实际25年以上的耐候性能外墙外保温体系在实际使用中会受到相当大的热应力作用。
Weathering test and engineering practice are closely related, can well reflect the high performance insulation board exterior wall insulation system for more than 25 years of weathering performance of exterior insulation system has considerable effect of thermal stress in practical use.
这种热应力主要表现在饰面层及抹面层上饰面层及抹面层温度在夏季阳光直射下可高达60~ 70 ℃,突降暴雨所引起的表面温度变化可达50℃之多二这就要求它能够经受住周期性热湿和热冷气候条件的长期作用。
The thermal stress is mainly manifested in the surface layer and the surface layer on the surface layer and the surface layer temperature can be as high as 60 to 70 degrees in the summer sun, the long-term effect of surface temperature changes caused by heavy rain up to 50 degrees more than this requires that it can withstand periodic heat wet and hot and cold climate conditions.
耐候性试验正是人工模拟这种严酷的高温降雨、冷热循环的加密组合:耐候性试验条件的组合是十分严厉的,通过该试验,不仅可检验外保温体系的长期耐候性能,而且还可对设计、施工和材料性能进行综合检验。

The weather resistance test is simulated in this high rainfall, severe cold cycle encryption combine weathering test condition is very serious, through the experiment, the long-term weathering performance can not only test the external insulation system, but also may carry on the comprehensive inspection of design, construction and material properties.
如果材料质量不符合要求,设计不合理或施工质量不好,都不可能经受住这样的考验。耐候性试验后应测试抹面层与保温层之间的拉伸粘结强度。
If the material quality does not meet the requirements, unreasonable design or construction quality is not good, it is impossible to withstand such a test. Should the tensile bond strength between surface layer and the insulating layer of the test after the weathering test.
耐冻融性能与体系吸水量有关饰面层有一定吸水量时,试样应包含饰面层。饰面层不吸水时,应对含饰面层和不含饰面层的两种试样分别进行试验。
If the resistance to freezing and thawing is related to the amount of water absorbed by the facing layer of the system, the sample should include the facing layer. When the facing layer does not absorb water, the two kinds of samples with decorative layer and non decorative layer should be tested separately.
