XPS挤塑板的一些小常识!

XPS挤塑板具有很好的保温隔热功能,可以保证整个产品的温度,可是劣质挤塑板的保温功能十分差,还没用多长时间,就会发现整个产品的结构都在变化。关于XPS挤塑板的一些小常识你知道吗?
XPS Extrusion board has good thermal insulation function, which can ensure the temperature of the whole product. However, the thermal insulation function of inferior Extrusion board is very poor. It will not take long to find that the structure of the whole product is changing. Do you know some common sense about XPS extrusion board?
XPS挤塑板是以聚苯乙烯树脂为原料加上其他的原辅料与聚合物,经过加热混合一起注入催化剂,然后挤塑压出成型而制作的硬质泡沫塑料板.它的学名为绝热用挤塑聚苯乙烯泡沫塑料(简称XPS),XPS具有很好的闭孔蜂窝结构,这种结构让XPS板有极低的吸水性(简直不吸水)、低热导系数、高抗压性、抗老化性(正常运用简直无老化分化现象)。具有高热阻、低线性、胀大比低的特色,其结构的闭孔率高,形成真空层,避免空气流动散热,保证其保温功能的耐久和安稳,相关于发泡聚氨酯的闭孔率,优势不言而喻。因而本资料是现在修建保温的很好的选择。XPS板用作保温资料,其保温功能和抗压强度等功能优于EPS板。
XPS Extrusion board is a rigid foam plastic board made of polystyrene resin as raw material and other raw and auxiliary materials and polymer, which is injected with catalyst through heating and mixing, then extruded and extruded. Its scientific name is extruded polystyrene foam for adiabatic use (XPS for short), XPS has a good closed-cell honeycomb structure, which makes XPS board have very low water absorption (almost no water absorption). Low thermal conductivity, high compressive resistance and aging resistance (no aging differentiation phenomenon in normal operation). It has the characteristics of high thermal resistance, low linearity and low expansion ratio. Its structure has high closure rate, forms a vacuum layer, avoids air flow and heat dissipation, and ensures the durability and stability of its heat preservation function. It is self-evident that its advantages are related to the closure rate of foamed polyurethane. Therefore, this inion is a good choice for building thermal insulation at present. XPS board is used as heat preservation material. Its functions of heat preservation and compressive strength are better than EPS board.

XPS挤塑板在保温行业的开展状况近几年来,挤塑成型的聚苯乙烯板在世界范围内得到广泛使用,这种新资料内部为闭孔结构,具有优异和耐久不变的保温功能、很强的憎水阻挠水蒸汽浸透的能力、适当高的抗压强度、加工容易、便于装置等特色,是现在世界上公认的适用于倒置屋面的抱负保温资料。挤塑聚苯乙烯的吸水率要比发泡聚苯乙烯要小10倍左右,且比泡沫玻璃还要低。实验还标明,该资料浸水之后仅在初阶段能吸入少数水份,随后就不再吸水,这一性质使它具有很好的保温功能且耐久不变,这一特色关于倒置保温屋面至关重要。此外,挤塑聚苯乙烯的水蒸汽浸透功能要比发泡聚苯乙烯小2~4倍,因而,这种保温资料既能阻挠雨水的浸入又能避免湿气浸透,然后避免了在资料内部因冷凝而积水,这是绝大多数保温资料望尘莫及的。

In recent years, XPS Extrusion board has been widely used in thermal insulation industry worldwide. This new material has closed-cell structure, excellent and durable thermal insulation function, strong hydrophobic resistance to water vapor immersion, appropriate high compressive strength, easy processing, easy installation and other characteristics. It is now recognized in the world. The ideal heat preservation data suitable for inverted roofs. The water absorption of extruded polystyrene is about 10 times smaller than that of expanded polystyrene and lower than that of foam glass. Experiments also show that the data can inhale a small amount of water only in the initial stage after immersion, and then no longer absorb water. This property makes it have good thermal insulation function and durability. This feature is very important for inverted thermal insulation roof. In addition, the water vapor permeation function of extruded polystyrene is 2-4 times smaller than that of foamed polystyrene. Therefore, this kind of heat preservation material can not only prevent rainwater immersion, but also avoid moisture immersion, and then avoid water accumulation due to condensation within the data, which is beyond the expectation of most heat preservation data.
XPS挤塑板在修建节能领域里的现状我国政府的能源方针是"开发和节省并重",把节省放在首位。节省能源依然是我国能源工业的战略要点。1986年建设部颁布了《民用修建节能规划规范》,其后又将规范的指标进一步进步。在施行修建节能规范以前,我国历年缔造住所面积累积近80亿平方米。从2000年起,对采暖区热环境差或能耗大的原有修建的节能改造作业现已开端。2005年重点城镇开端成片进行修建热环境及节能改造。而XPS挤塑板由于具有低导热系数、质轻、高强、防水、防渗、便于施工等优异功能,所以在节能住所中极具吸引力。新建住所将从规划、规划、相关资料及设备的使用等方面采取节能办法,进步住所质量,提倡运用新资料、新技术、新工艺、带动修建挤塑板燃烧等级资料工业的升级换代。所以要有更高水平的绝热资料及绝热技术,XPS挤塑板迎合这一开展趋势,所面对的将是一个潜力巨大的商场。
The current situation of XPS Extrusion board in the field of building energy-saving Our government's energy policy is to lay equal stress on development and saving, and put saving first. Energy conservation is still the strategic point of China's energy industry. In 1986, the Ministry of Construction promulgated the Code for Energy Conservation Planning of Civil Construction, and then made further progress in the normative indicators. Prior to the implementation of the building energy conservation code, China has built nearly 8 billion square meters of residential area over the years. Since 2000, the energy-saving renovation of the original buildings with poor thermal environment or high energy consumption in heating areas has begun. In 2005, key cities and towns began to build thermal environment and transform energy-saving. XPS Extrusion board is very attractive in energy-saving residence because of its excellent functions such as low thermal conductivity, light weight, high strength, waterproof, impermeability, easy construction and so on. New dwellings will adopt energy-saving measures in planning, planning, use of relevant inion and equipment, improve the quality of dwellings, advocate the use of new inion, new technology, new technology, and promote the upgrading of the inion industry for building Extrusion board combustion grade. Therefore, XPS Extrusion board will face a market with huge potential if we want to have higher level of insulation inion and technology to meet this development trend.
