挤塑板具备的性能特点
Performance characteristics of extruded panels
1、优良的保温隔热性
1. Excellent insulation.
具有高热阻、低线性、膨胀比低的特点,其结构的闭孔率达到了99%以上,形成真空层,避免空气流动散热,确保其保温性能的持久和稳定,相对于发泡聚氨酯80%的闭孔率,优势不言而喻。实践证明20mm厚的XPS挤塑保温板,其保温效果相当于50mm厚发泡聚苯乙烯,120mm厚水泥珍珠岩。
With high thermal resistance, low linearity and low expansion ratio, the closed-cell rate of the structure has reached over 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the durability and stability of its insulation performance. Compared with the 80% closed-cell rate of foamed polyurethane, the advantages are self-evident. Practice has proved that 20 mm thick XPS Extrusion insulation board, its insulation effect is equivalent to 50 mm thick foamed polystyrene, 120 mm thick cement perlite.
2、产品环保性能
2, product environmental performance
XPS板经国家有关部门检测起化学性能稳定,不挥发有害物质,对人体无害,生产原料采用环保型材料,不产生任何工业污染。该产品属环保型建材。
The XPS board has been tested by the relevant departments of the state with stable chemical performance, no volatile harmful substances, harmless to the human body, environmental-friendly raw materials for production, no industrial pollution. The product is environmentally-friendly building materials.
3、较好的憎水、防潮性
3. Better hydrophobicity and moisture resistance.
吸水率是衡量保温材料的一个重要参数。保温材料吸水后保温性能随之下降,在低温情况下,吸入的水极易结冰,破坏了保温材料的结构,从而使板材的抗压及保温性能下降。由于聚苯乙烯分子结构本身不吸水,板材分子结构稳定,无间隙,解决了其它材料漏水、渗透、结霜、冷凝等问题。
Water absorption is an important parameter for measuring thermal insulation materials. After absorbing water, the insulation performance of the insulation material decreases. At low temperature, the water sucked in is easy to freeze, destroying the structure of the insulation material, thus reducing the compressive and thermal insulation performance of the board. Because the polystyrene molecular structure itself does not absorb water, the plate molecular structure is stable, no gap, to solve other materials leakage, penetration, frosting, condensation and other problems.
4、质地轻、使用方便
4. Light weight and easy to use.
XPS板的完全闭孔式发泡化学结构与其蜂窝状物理结构,使其具有轻质、高强度的特性,便于切割、运输,且不易破损、安装方便。
The chemical structure of XPS board and its honeycomb-like physical structure make it light weight and high strength, easy to cut, transport, easy to break and install.
5、稳定性、防腐性好
5. Good stability and corrosion resistance.
长时间的使用中,不老化、不分解、不产生有害物质,其化学性能相对稳定,不会因吸水和腐蚀等导致降解,使其性能下降,在高温环境下仍能保持其优越的性能,根据有关资料介绍,XPS挤塑保温板即使使用30~40年,仍能保持优异的性能,且不会发生分解或霉变,没有有毒物质的挥发。
The chemical properties of XPS extruded heat preservation board are relatively stable and will not degrade due to water absorption and corrosion. It can still maintain its superior performance in high temperature environment. According to relevant information, XPS extruded heat preservation board can be maintained even after 30-40 years of use. Excellent performance, no decomposition or mildew, no volatilization of toxic substances.
6、高强度抗压性
6. High strength compressive strength
由于XPS板的特殊结构,其抗压强度较高、抗冲击性极强,根据XPS的不同型号及厚度其抗压强度达到150~500Kpa以上,能承受各系统地面荷载,广泛应用于地热工程、高速公路、机场跑道、广场地面、大型冷库及车内装饰保温等领域。因此本材料是目前建筑保温的较好之选。
Because of the special structure of XPS board, its compressive strength is high and its impact resistance is very strong. According to the different types and thickness of XPS, its compressive strength reaches 150-500 Kpa and can withstand the ground load of various systems. It is widely used in geothermal engineering, expressway, Airport runway, square ground, large-scale cold storage and interior decorative insulation collar. Domain. Therefore, this material is a good choice for building insulation at present.
