XPS挤塑板的优点有哪些?

  挤塑板是以聚苯乙烯树脂为原料加上其他的原辅料与聚含物,通过加热混合同时注入催化剂,然后挤塑压出成型而制造的硬质泡沫塑料板。下面为大家介绍XPS保温材料的优缺点。 XPS材料的优点
The extruded board is a rigid foamed plastic sheet made of polystyrene resin as raw material, other raw materials, accessories and polymer inclusions, which is heated, mixed and injected with catalyst at the same time, then extruded and extruded. Below for you to introduce the advantages and disadvantages of XPS thermal insulation materials. Advantages of XPS Materials
1、价格与EPS系统相比较高。
1. The price is higher than that of EPS system.
2、吸胶性差,粘结后破坏面为XPS板表面,粘结强度不够。
2. The adsorbability is poor, the failure surface after bonding is XPS board surface, and the bonding strength is not enough.
3、其结构的伸缩性差,受温度及湿度的变化影响而变形、起鼓导致保温层脱落。
3. Its structure has poor flexibility and is deformed and bulged due to the change of temperature and humidity, which causes the insulation layer to fall off.
4、近3~4年才尝试性使用,国内尚无国家标准;欧美、韩国等保温技术先进国家尚无推广使用。

4. It has only been tried in the past 3-4 years, and there is no national standard in China; advanced countries of insulation technology such as Europe, America and Korea have not yet been popularized.

5、由于内层的闭孔结构。因此它具有良好的抗湿性,在潮湿的环境中,仍可保持良好的保温隔热性能;适用于冷库等对保温有特殊要求的建筑,也可用于外墙饰面材料为面砖或石材的建筑。
5. Because of the closed-hole structure of the inner layer. Therefore, it has good humidity resistance, in the humid environment, can still maintain good thermal insulation performance; suitable for cold storage and other buildings with special requirements for thermal insulation, can also be used for exterior wall decoration materials for brick or stone buildings.
6、XPS挤塑板具有致密的表层及闭孔结构内层。其导热系数大大低于同厚度的EPS,因此具有较EPS更好的保温隔热性能。对同样的建筑物外墙,其使用厚度可小于其它类型的保温材料。
6. XPS Extrusion board has dense surface and closed-cell structure. The thermal conductivity of EPS is much lower than that of EPS with the same thickness, so EPS has better thermal insulation performance. For the same building exterior wall, its thickness can be less than other types of insulation materials.
7、XPS挤塑板本身的强度较高,从而造成板材较脆,不易弯折,板上存在的应力时应力集中,容易使板材损坏、开裂。
7. XPS extruded sheet has high strength, which makes the sheet brittle and not easy to bend. The stress concentration in the sheet is easy to damage and crack.
