挤塑板的优良与劣质在使用方面较大区别

文章来源:https://www.sdjnxps.com/作者:震辉保温材料 发布时间: 2021-07-30
不同质量的挤塑板自然也会存在着某些区别,那到底有着怎样的差距呢?且看山东挤塑板小编为您总结的不同的挤塑板之间的区别,希望对您的日后使用有所帮助。
Naturally, there are some differences between extruded boards of different quality. What is the difference? Take a look at the differences between different Extruded Boards summarized by Shandong extruded board editor, hoping to be helpful for your future use.
挤塑板起保温隔热作用,应用于建筑物屋面保温、钢结构屋面、建筑物墙体保温、建筑物地面保湿、广场地面、地面冻胀控制、中央空调通风管道、机场跑道隔热层、高速铁路路基等。
Extruded board plays the role of thermal insulation and is applied to building roof insulation, steel structure roof, building wall insulation, building ground moisture preservation, square ground, ground frost heave control, central air conditioning ventilation duct, airport runway thermal insulation layer, high-speed railway subgrade, etc.
挤塑板具有高热阻、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。
The extruded board has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure reaches 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 with the 80% closed cell rate of foamed polyurethane, its advantage is self-evident.

先来说说优良的挤塑板具有很高的容重,使墙体温度和室内温度非常接近,也就是说在室内温度上升和下降的同时,挤塑板可以通过调节吸热和放热的不同保持室内温度是在一个稳定的范围内。在冬天可以阻隔室内热能向外传出,较少消耗;在夏天则可以阻挡室外的热量向内传输,也就是我们常说的通暖夏凉。
First of all, excellent Extruded Boards have high bulk density, which makes the wall temperature very close to the indoor temperature. That is to say, when the indoor temperature rises and falls, extruded boards can keep the indoor temperature in a stable range by adjusting the difference between heat absorption and heat release. In winter, it can block the indoor heat energy from going out and consume less; In summer, it can block the inward transmission of outdoor heat, that is, we often say that it is warm and cool in summer.
而关于劣质的挤塑板在原料的选择上就已经落后了,大都会使用回收的塑料泡沫,如饭盒等加工而成,除了容重方面存在很大的差别,抗压性能也很差,在使用后很容易造成变形开裂的现象发生。由于这种挤塑板含有大量的杂质,一旦发生火灾,不但不能防火还会成为助燃剂,对人体的生命安全构成巨大的威胁。
The selection of raw materials for low-quality extruded boards has fallen behind. Most of them are processed with recycled plastic foam, such as lunch boxes. In addition to the great difference in bulk weight, the compressive performance is also very poor, which is easy to cause deformation and cracking after use. Because this kind of extruded board contains a lot of impurities, in case of fire, it will not only fail to prevent fire, but also become a combustion promoter, which poses a great threat to human life safety.
此外您在选购该产品时要知道不同品牌,产品质量不同,整体特性表现也不一样。大家在选择上,一定要有所筛选,高中低档,真的一分钱一分货。
In addition, when choosing this product, you should know that different brands, different product quality, and different overall characteristics. In terms of choices, we must select some. High, middle and low grades, you really get what you pay for.
挤压板是建筑结构中常用的一种,具有良好的保温和防火效果。挤塑板的质量影响着保温效果,所以选购质量好的挤塑板就十分重要。具体的问题您可以来关注我们网站https://www.sdjnxps.com得到解答。
Extruded plate is a kind of commonly used building structure, which has good thermal insulation and fire prevention effect. The quality of extruded board affects the insulation effect, so it is very important to choose high-quality extruded board.
