苯板和挤塑板的区别主要体现在哪?

  苯板是一个大快,然后使用钨丝,宽度,长度,厚度可以根据需求,减少挤压板的宽度是一定的,如果客户没有特殊要求制造商不会改变规格,但长度可以根据需求设置,减少由切割完成工作表后。
Benzene plate is a big fast, then use tungsten wire, width, length, thickness according to demand, reduce the width of the extrusion plate is certain, if the customer does not have special requirements manufacturers will not change specifications, but the length can be set according to demand, reduce by cutting completed worksheet.
挤压板与苯板的区别:
The difference between extrusion plate and benzene plate:
1. 隔热性能:
1. Insulation performance:
相同厚度的EPS和XPS绝缘性能逐渐提高。EPS为0.041,XPS为0.030。因此,在相同保温效果下,XPS板的厚度比EPS板薄,但纯板的价格要高于XPS板。如果将工艺和建筑高度考虑在内,每平方米XPS的价格实际上要比EPS贵。
The insulation performance of EPS and XPS with the same thickness is gradually improved. EPS was 0.041 and XPS was 0.030. Therefore, under the same thermal insulation effect, the thickness of XPS plate is thinner than that of EPS plate, but the price of pure plate is higher than that of XPS plate. If process and building height are taken into account, the price of XPS per square meter is actually higher than that of EPS.
保温方面,主要是热惯性指标D, D值与蓄热系数成正比。但就整个系统而言,200mm混凝土的蓄热量足够大,外保温层完全可以满足节能要求。这也是国家规范要求墙体综合导热系数和蓄热系数同时满足要求的原因。目前EPS或XPS薄抹灰系统完全满足要求。
In terms of heat preservation, the main thermal inertia index D is proportional to the thermal storage coefficient. However, as far as the whole system is concerned, the heat storage capacity of 200 mm concrete is large enough, and the external insulation layer can fully meet the requirements of energy saving. This is also the reason why the comprehensive thermal conductivity and thermal storage coefficient of the wall are required to meet the requirements in the national code. At present, EPS or XPS thin plastering system fully meets the requirements.
2. 强度:
2. strength:
这里显示的强度应该是抗拉强度。聚苯乙烯板的容重与拉伸强度有绝对关系。容重为18Kg/m3的EPS抗拉强度为110 ~ 120KPa,而容重为20Kg/m3的EPS抗拉强度约为140KPa。XPS的容重一般在25Kg到45Kg之间,强度在150KPa到700KPa或更高。(前提是满足导热系数约为0.03)。
The strength shown here should be tensile strength. There is an absolute relationship between the bulk density and the tensile strength of polystyrene sheets. The tensile strength of EPS with bulk density of 18 Kg/m3 is 110 ~ 120 KPa, while that of EPS with bulk density of 20 Kg/m3 is about 140 KPa. The bulk density of XPS is generally between 25kg and 45kg, and the strength is between 150KPa and 700KPa or higher. (The premise is that the thermal conductivity is about 0.03).

电流强度的XPS板200 kpa 250 kpa,国内许多XPS板的强度,EPS板材100 kpa,在日益丰富的立面装饰和沿海地区台风,强度是非常重要的,特别是对于一些外墙瓷砖或高级两个板都需要加强或者使用固定辅助固定。瓷砖画要大于400 kpa,甚至XPS不能承担,解决方案是通过膨胀螺栓固定钢丝网的基本水平来解决,这可以分发给三维空间拉伸应力,所以只要安克雷奇是合适的,把损害必须复合钢网的抗裂砂浆层,并不是一个大问题。

Current intensity of XPS board 200 kPa 250 kpa, many domestic XPS board strength, EPS board 100 kpa, in the increasingly abundant facade decoration and coastal typhoon, strength is very important, especially for some external wall tiles or advanced two boards need to be strengthened or fixed auxiliary. Ceramic tile painting should be more than 400 kpa, or even XPS can not bear. The solution is to fix the basic level of wire mesh by expansion bolts, which can be distributed to three-dimensional space tensile stress. So as long as Anchorage is appropriate, the crack-resistant mortar layer of composite steel mesh is not a big problem.
与EPS相比,XPS板的强度较高,但与EPS相比,由于XPS板的性质(脆性),当粘结面积较大时,外墙单板层开裂的可能性较大,尤其是涂层面层。柔性是材料的问题,以饰面为例,通常感知到的饰面是应用于聚苯乙烯板材上的,然后看看聚苯乙烯板材弯曲表面有多远不会出现裂纹,弹性好,弯曲几圈也不会出现裂纹。类似于防水材料的延性指数。但在材料本身上,柔性EPS优于XPS。
Compared with EPS, the strength of XPS board is higher, but compared with EPS, because of the nature of XPS board (brittleness), when the bonding area is larger, the possibility of cracking of external wall veneer layer is greater, especially the coating layer. Flexibility is a matter of materials. For example, decoration is usually perceived to be applied to polystyrene sheets. Then we can see how far the bending surface of polystyrene sheets is without cracks, good elasticity and no cracks in several bending circles. Ductility index similar to waterproof material. But in material itself, flexible EPS is better than XPS.
3.耐气候性:
3. Climate tolerance:
耐候性是指保温系统对外界天气变化的适应性,是指系统整体稳定性、保温效果在不同气候条件下是否发生变化等一系列质量问题。耐候性是保温系统的一项重要指标。
Weatherability refers to the adaptability of thermal insulation system to the changes of external weather. It refers to a series of quality problems such as the overall stability of the system and whether the thermal insulation effect changes under different climatic conditions. Weatherability is an important index of thermal insulation system.
由于EPS板与XPS相比吸水率较高,其耐候性不如XPS系统。但EPS板的延性优于XPS板,克服了某些缺陷。但就体系而言,薄抹灰体系本身的涂层具有一定的防水能力。除了施工期间,这两种系统都是防水的。雨水在外墙与墙面的接触是垂直的,只要表面砂浆不开裂,防水就没有问题。
Because EPS board has higher water absorption than XPS, its weatherability is not as good as XPS system. But the ductility of EPS board is better than that of XPS board, which overcomes some defects. But as far as the system is concerned, the coating of the thin plastering system itself has certain waterproof ability. Except during construction, both systems are waterproof. Rainwater contact with the wall is vertical, as long as the surface mortar does not crack, waterproofing is no problem.
此外,风压阻力也是影响耐候性的一个重要因素,因为系统空腔风压阻力越大,风压阻力越差。所以关键是要看整个保温系统和底座粘结面积的大小。这个XPS系统和EPS系统都没问题。
In addition, wind pressure resistance is also an important factor affecting weather resistance, because the greater the air pressure resistance in the system cavity, the worse the wind pressure resistance. So the key is to see the size of the whole insulation system and the bonding area of the base. This XPS system and EPS system are all right.
