挤塑板跟一般保温板有什么区别
作者:admin 来源:本站 发布时间:2017-10-12 15:24:11 浏览次数:329
挤塑板是一种专业的外墙保温板,但挤塑板跟一般保温板的性能是有所区别的,下面山东挤塑板厂家就来说说挤塑板与普通保温板的性能对比。

Extrusion board is a kind of professional exterior wall insulation board, but the performance of the extruded board is different from that of the ordinary insulation board. The following Shandong Extrusion board manufacturers come to talk about the performance comparison between the Extrusion board and the ordinary heat preservation board.

在耐候性方面,耐候性具体指的是保温系统对外界天气变化的适应能力,指在不同的气候条件下,系统的整体稳定性、保温效果是否有变化等有关质量的系列问题,耐候性是保温系统较为重要的一个指标。由于EPS板和XPS相比有较高的吸水性,所以其耐候性比不上XPS系统。当前成熟的外墙保温系统每层都会考虑到防水性,因为吸水之后板材的保温性能和耐候性都会大大降低。
In the weather resistance, weather resistance refers to changes of external thermal insulation system's ability to adapt to the weather, in different climatic conditions, a series of problems whether the effect of changes relating to the quality of the overall system stability and thermal insulation, weather resistance is an important index of insulation system. Because the EPS board has higher water absorption than XPS, its weatherability is not comparable to that of XPS system. At present, the mature exterior wall insulation system will take into account the waterproof property, because after absorbing water, the insulation property and weather resistance of the plate will be greatly reduced.
由于EPS吸水性较强,吸水后会降低保温性能,使板材变软,再加上本身强度也比较低,对施工时候的天气要求高,若是在施工中吸了水又没有彻底晒干的话,其弱点就显现无疑。 耐风压性能也是耐候性中的非常重要的一项,因此重点就是要看整个保温体系跟基层的粘结面积大小,还有就是要看耐风压试验的风的级别和南方的台风相比起来会产生何种结果。
EPS due to strong water absorption, water will reduce the insulation performance, the material becomes soft, coupled with its strength is relatively low, when the weather on the construction requirements, if in the construction of absorbed water and not completely dried, its weakness becomes apparent. Wind resistant performance is weathering in a very important, so the key is to look at the whole insulation system with the bonding area, there is to see the south wind level and pressure resistance test of the typhoon compared to what is expected as a result of.
