EPS和XPS系统的性能比较
作者:admin 来源:本站 发布时间:2017-10-14 11:34:03 浏览次数:343
目前的保温板材外墙外保温系统主要有:EPS板外墙保温系统、XPS板外墙保温系统
At present, the external thermal insulation system of thermal insulation board mainly includes: EPS board external wall insulation system, XPS board external wall insulation system
1、保温隔热性能:
1, insulation performance:

相同厚度的EPS以及XPS保温性能是逐渐升高的。EPS为0.041,XPS是0.030。因此达到相同的保温效果的情况下,XPS板材比EPS板材厚度要薄,但纯板材的价格XPS板贵于EPS板。如果全面考虑工艺以及建筑物高度,每平方米的价格XPS反而比EPS要贵一些。

 地暖挤塑板

The insulation properties of EPS and XPS with the same thickness are gradually increased. EPS was 0.041, XPS was 0.030. Therefore, to achieve the same insulation effect, XPS sheet is thinner than EPS plate, but the price of pure board is higher than that of EPS board on XPS board. If you take full account of the craft and building height, the price per square meter XPS is more expensive than EPS.
对于隔热来讲,主要是看热惰性指标D,而D值与蓄热系数成正比。但是就整个系统而言,200mm的混凝土的蓄热已经够大,再加外保温层,完全满足节能要求。这也是国家规范要求墙体综合导热系数和蓄热系数要同时满足要求的原因。目前的EPS或XPS薄抹灰系统都完全满足要求。
For heat insulation, the thermal inertia index D is mainly observed, while the D value is directly proportional to the heat storage coefficient. However, as far as the whole system is concerned, the heat storage of 200mm concrete is large enough, and the external insulation layer can fully meet the energy conservation requirements. This is also the reason that the comprehensive thermal conductivity and heat storage coefficient of the wall should be satisfied at the same time. The current EPS or XPS thin plastering system is 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25Kg~45Kg,强度从150KPa~700KPa或更高。
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 25Kg to 45Kg, and the strength is from 150KPa to 700KPa or higher.
与EPS相比,XPS板的强度要高,不过与XPS相比由于EPS板材的性质,在粘贴面积较大时,外墙饰面层开裂的可能性高,尤其是涂料面层。 柔韧性是材性的问题,拿抹面来说,感性认识通常将抹面批抹在聚苯板上,然后看聚苯板弯曲到什么程度抹面还不出现裂缝,柔韧性好的话弯几个圈都不会裂的。
Compared with EPS, the strength of XPS board is higher, but compared with XPS, because of the property of EPS board, the possibility of cracking of exterior wall facing layer is higher when the paste area is larger, especially the coating surface layer. Flexibility is the material problems with precausions, perceptual knowledge will usually be put in plaster group of polystyrene board, polystyrene board and see to what extent is not precausions bending cracks, flexibility and good words will not crack bending circle.
