是由聚苯乙烯树脂及其它添加剂经挤压过程制造出的拥有连续均匀表层及闭孔式蜂窝结构的板材。 Extruded board is a board with continuous and uniform surface layer and closed-cell honeycomb structure manufactured by polystyrene resin and other additives through the extrusion process. 导热系数 和优良保温和抗压性能，挤塑板 质量的优劣 怎么辨别呢，下面一起了解一下 。 These thick plates of honeycomb structure will not have gaps. The heat insulation material of this closed-cell structure can have different pressures, and at the same time have the same low thermal conductivity and excellent heat preservation and compression performance. The quality of the extruded plate How to distinguish it, let's find out below .
Discriminating the quality of the extruded board mainly depends on these aspects:
1. Excellent thermal insulation
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，领先优势不言而喻。 It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closed cell ratio of more than 99% , forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the durability and stability of its thermal insulation performance, compared to 80% of foamed polyurethane . The closed-cell ratio and leading edge are self-evident. 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。 Practice has proved that the thermal insulation effect of 20mm thick XPS extruded insulation board is equivalent to 50mm thick expanded polystyrene and 120mm thick cement perlite. Therefore, this material is the best choice for building insulation.
2.Excellent high strength compression resistance
XPS 板的特殊结构，其抗压强度极高、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。 Due to the special structure of the XPS board, its compressive strength is extremely high and its impact resistance is very strong. According to the different models and thicknesses of the XPS , its compressive strength can reach more than 150-500Kpa . Highways, airport runways, square grounds, large cold storages, and interior decoration and insulation.
3.High-quality water-repellent and moisture-proof properties
保温材料 的一个重要参数。 Water absorption is an important parameter for measuring insulation materials . The thermal insulation performance of the thermal insulation material decreases after it absorbs water. Under low temperature conditions, the absorbed water is likely to freeze, which damages the structure of the thermal insulation material, thereby reducing the compression and thermal insulation performance of the board. Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the sheet is stable and has no gaps, which solves the problems of water leakage, penetration, frosting, and condensation of other materials.
4 , light texture and easy to use
XPS board's completely closed-cell foaming chemical structure and its honeycomb-like physical structure make it lightweight, high-strength, easy to cut and transport, not easy to break, and easy to install.
5.Good stability and corrosion resistance
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。 During long-term use, it does not age, decompose, and produce no harmful substances. Its chemical properties are extremely stable, and it will not be degraded due to water absorption and corrosion, which will reduce its performance and maintain its superior performance in high temperature environments. According to the introduction of related materials, even if XPS extruded insulation board is used for 30 to 40 years, it can still maintain excellent performance without decomposition or mildew, and there is no volatilization of toxic substances.
6 , product environmental performance
The XPS board has been tested by relevant national departments for stable chemical properties, non-volatile harmful substances, and harmless to human body. The production raw materials are made of environmentally friendly materials without any industrial pollution. This product is an environmentally friendly building material.
挤塑板 常常会造成灾难。 Poor quality extruded boards often cause disaster. ……一幢幢美丽的大楼变成了黑色的焦炭，无数生命刹那间被火魔吞噬。 The fire in the teacher's apartment in Shanghai, the Wanxin building in the Shenyang dynasty ... all beautiful buildings became black coke, and countless lives were swallowed up by the fire demon. 挤塑板失去阻燃性能导致火势大肆蔓延。 One of the reasons for the fire was that the XPS extruded board lost flame retardancy and caused the fire to spread. Therefore, it is important to choose a good quality extruded board.
