选择XPS挤塑板的理由
作者:admin 来源:本站 发布时间:2017-11-16 13:36:18 浏览次数:491
目前高效能的外墙外保温系统主要有:XPS外墙保温系统和EPS保温系统。
At present, the high efficiency exterior wall external thermal insulation system mainly includes: XPS external wall insulation system and EPS insulation system.
1、保温隔热性能:
1, insulation performance:

EPS以及XPS保温性能是逐渐升高的。EPS为0.045,XPS是0.028。因为外墙装饰厚度在满足保温等各项性能指标的情况,越薄越好。如果全面考虑工艺以及建筑物高度,EPS和XPS每平方米的价格相差不多。目前EPS或XPS薄抹灰系统都完全满足要求。

The insulation properties of EPS and XPS are gradually increased. EPS was 0.045, XPS was 0.028. Because the thickness of the external wall decoration meets the performance indicators such as insulation, the thinner the better. If the process and building height are fully considered, the price of EPS and XPS will vary little per square meter. At present, EPS or XPS thin plastering system can fully meet the requirements.
2、强度:
2, strength:
这里指出的强度应该是抗拉强度,聚苯板的容重和抗拉强度有绝对的关系,一般的EPS容重18Kg/m3的抗拉强度为110~120KPa,20Kg/m3容重的在140KPa左右。XPS的容重正常从26Kg~45Kg,强度从150KPa~700KPa或更高,与EPS相比,XPS板的强度要高,所以在外饰面是面砖的时候还是XPS系统比较稳定,而且其承重能力也比EPS系统要高。
The strength that should be pointed out here is tensile strength. The bulk density and tensile strength of the polystyrene board are absolutely related. The tensile strength of the general EPS bulk density 18Kg/m3 is 110 ~ 120KPa, and the 20Kg/m3 bulk density is about 140KPa. The bulk density of XPS is normal from 26Kg to 45Kg, and the strength is from 150KPa to 700KPa or higher. Compared with EPS, the strength of XPS board is higher, so the XPS system is stable when the outside facing is tile, and its bearing capacity is higher than that of EPS system.
3、耐候性:
3, weather resistance:
耐候性是指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。耐候性是保温系统的一个非常重要的指标。目前成熟的外墙外保温系统每一层都考虑到防水性,因为吸水后保温性能耐候性会大大下降。
Weather resistance refers to the adaptability of the heat preservation system to the external weather changes. It refers to the series of problems concerning the overall stability of the system and the change of the heat preservation effect under different climatic conditions. Weather resistance is a very important index of thermal insulation system. At present, each layer of mature exterior insulation system takes into account the waterproof property, because the moisture insulation property will be greatly reduced after water absorption.
