山东挤塑板xps系统与eps系统强度比较

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
It is pointed out that the strength should be tensile strength, the bulk density and tensile strength of polystyrene board has an absolute relationship, the general EPS bulk density 18Kg/m3 resistance
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~
The tensile strength is 110 ~ 120KPa, and the bulk density of 20Kg/m3 is about 140KPa. The bulk density of XPS is normal from 25Kg to 45Kg, and the strength is from 150KPa to

700KPa或更高。(前提是满足导热系数0.03左右)。

700KPa or higher. (the premise is to meet the thermal conductivity of about 0.03).
目前XPS板强度在200KPa-250KPa,这种强度国内很多XPS板材做不到,EPS板材在100KPa以下,在越来越
The XPS board strength in 200KPa250KPa, the strength of domestic a lot of XPS plate can not do, EPS panel below the 100KPA, in more and more
丰富的外立面装饰以及沿海地区经常有台风出现的情况下,强度显得很重要,特别是对于一些外墙贴砖
Rich Wailimian decoration and coastal areas often have typhoon strength is very important, especially for some exterior wall tile
或者高层而言,两种板材均需加固或者说采用固定件辅助固定。瓷砖的拉拔要大于400KPa,即使是XPS也
Or high, the two plates are needed to reinforce or use a fixed part of the auxiliary fixed. The drawing of ceramic tile should be more than 400KPa, even if it is XPS
不能承受,解决的方法是通过胀栓锚固钢丝网到基层解决,这样可以向三维空间分散拉应力,所以只要
Can not afford to solve the method is through the expansion bolt and anchor wire mesh to the base to solve, so that the three-dimensional space can be scattered to pull the stress, so as long as the
锚固得当,拉拔破坏处肯定在复合钢丝网的抗裂砂浆层,不是大问题。
When the anchorage is properly, the breaking point of the drawing is sure to be the anti crack mortar layer in the composite steel wire mesh, not a big problem.
与EPS相比,XPS板的强度要高,不过与EPS相比由于XPS板材的性质(脆性),在粘贴面积较大时,外墙
Compared with XPS, the strength of the EPS board is higher, but compared with the EPS because of the nature of the XPS plate (brittle), in the larger area, the outer wall
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
The possibility of cracking of the facing layer is high, especially the coating surface layer. Flexibility is the material problems with precausions, perceptual knowledge will usually precausions group
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。
Wipe the polyphenyl plate, and then look at the polyphenyl plate bending to what extent plaster is not crack, good flexibility of the bend a few laps will not crack.
类似于防水材料中的延展性指标。但是就材料本身而言,柔韧性EPS要优于XPS。
Similar to the ductility index of waterproof materials. But in terms of the material itself, the flexibility of EPS is better than XPS.
