挤塑聚苯板的存在优势和不足?

  挤塑聚苯板是现在建筑施工过程中经常使用的一种保温材料,俗话说人无完人挤塑板保温材料也是如此,挤塑板厂家提醒您挤塑板在具有很多挤塑聚苯板优点的同时也存在一些不足之处。

  Extruded polystyrene board is a kind of thermal insulation material often used in the process of construction now. As the saying goes, no one is perfect. So is the insulation material of extruded polystyrene board. The manufacturer of extruded polystyrene board reminds you that the extruded polystyrene board has many advantages and disadvantages.

  挤塑板的缺点在于本身的强度很高,导致板材比较脆,不易弯折,板材上出现集中用力的时候,容易出现损坏,开裂的情况;挤塑板的透气性比较差,如果板材两侧的温差较大就会出现凝结现象;伸缩性也较差,在温度变化较大的环境中容易出现起鼓、变形甚至脱落的现象,而且由于出现时间不长国内并没有出台国家标准,价格也比EPS系统要高。

  The disadvantage of extruded board is that its strength is very high, which makes the plate brittle and not easy to bend. When concentrated force occurs on the plate, it is easy to damage and crack; the air permeability of extruded plate is relatively poor, if the temperature difference between the two sides of the plate is large, condensation will occur; and the expansion is also poor, and it is easy to bulge, deform and even fall off in the environment with large temperature change The price is higher than that of EPS system because it has not been issued national standard for a short time.

  当然挤塑板还有很多的优点比如具有致密的表层和内部的闭孔结构,相对于EPS来说导热系数大大降低,这样的结构也使得挤塑板具有良好的抗湿性,即使在潮湿的环境中也可以实现优良的保温性能,在建筑保温方面有着广泛的应用。

  Of course, there are many advantages of extruded panel, such as dense surface and internal closed cell structure. Compared with EPS, the thermal conductivity is greatly reduced. This structure also makes the extruded panel have good moisture resistance. Even in humid environment, it can also achieve excellent thermal insulation performance, which has a wide range of applications in building thermal insulation.
