| 挤塑保温板发展现状 Development status of extruded thermal insulation board 保温行业 Thermal insulation industry 近几年来，挤塑成型的聚苯乙烯板在世界范围内得到广泛应用，这种新材料内部为闭孔结构，具有优异和持久不变的保温性能、极强的憎水阻止水蒸汽渗透的能力、相当高的抗压强度、加工容易、便于安装等特点，是目前世界上公认的适用于倒置屋面的理想保温材料。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。试验还表明，该材料浸水之后仅在最初阶段能吸入少量水份，随后就不再吸水，这一性质使它具有极佳的保温性能且持久不变，这一特点对于倒置保温屋面至关重要。此外，挤塑聚苯乙烯的水蒸汽渗透性能要比发泡聚苯乙烯小2~4倍，因此，这种保温材料既能阻止雨水的浸入又能防止湿气渗透，从而避免了在材料内部因冷凝而积水，这是绝大多数保温材料望尘莫及的。 In recent years, extruded polystyrene boards have been widely used in the world. This new material is a closed structure with excellent and persistent insulation properties, strong water repellent ability to prevent water vapor infiltration, high compressive strength, easy processing, easy installation and so on. It is the present world. It is generally accepted as ideal thermal insulation material for inverted roofing. The water absorption of extruded polystyrene is about 10 times smaller than that of expanded polystyrene and lower than that of foam glass. The test also shows that the material can inhale only a small amount of water in the initial stage and then no longer absorb water. This property makes it excellent in thermal insulation performance and persists, which is very important for the inverted thermal insulation roof. In addition, the water vapor permeability of the extruded polystyrene is 2~4 times smaller than that of the foamed polystyrene. Therefore, this thermal insulation material can prevent the immersion of the rainwater and prevent the infiltration of moisture, thus avoiding the accumulation of water inside the material because of condensation. This is the overwhelming majority of thermal insulation. 建筑行业 construction industry 我国政府的能源方针是"开发和节约并重"，把节约放在首位。节约能源依然是中国能源工业的战略要点。1986年建设部颁布了《民用建筑节能设计标准》，其后又将标准的指标进一步提高。在实施建筑节能标准以前，我国历年建造住宅面积累积近80亿平方米。从2000年起，对采暖区热环境差或能耗大的原有建筑的节能改造工作已经开始。2005年重点城镇开始成片进行建筑热环境及节能改造。而XPS由于具有低导热系数、质轻、高强、防水、防渗、便于施工等优异性能，所以在节能住宅中极具吸引力。 Our government's energy policy is "developing and economizing equally" and giving priority to saving. Energy conservation is still the strategic point of China's energy industry. In 1986, the Ministry of Construction promulgated the "standard for energy efficiency design of civil buildings". Before the implementation of building energy efficiency standards, China's construction area accumulated nearly 8 billion square meters over the years. Since 2000, the energy saving reconstruction of the old buildings in the heating area with poor thermal environment or large energy consumption has begun. In 2005, the key cities and towns began to build up thermal environment and energy saving transformation. Because of its excellent performance such as low thermal conductivity, light weight, high strength, waterproof, impervious, and convenient for construction, XPS has great attraction in energy-saving residential buildings. “十五”期间，我们的住宅建设还会有一个巨大的发展。现在城市建筑的保有量大概是70多亿平米，其中住宅有40多亿平米，在未来十年城乡还要建57亿平米的住宅，其中城市27亿平米，农村30亿平米。在这个情况下，保温材料的发展要产业化。以前我们只搞了1.8亿平米的节能住宅，远远达不到节能的要求。新建住宅将从规划、设计、相关材料及设备的应用等方面采取节能措施，提高住宅质量，提倡使用新材料、新技术、新工艺、带动建筑材料工业的升级换代。所以要有更高水平的绝热材料及绝热技术，XPS挤塑保温板迎合这一发展趋势，所面对的将是一个潜力巨大的市场 。 During the "fifteen" period, our housing construction will have a great development. There are about about 7000000000 square meters of urban construction, of which there are about 4000000000 square meters of housing. In the next ten years, there are 5 billion 700 million square meters of residential buildings in urban and rural areas, including 2 billion 700 million square meters in cities and 3 billion square meters in rural areas. In this case, the development of thermal insulation materials should be industrialized. In the past, we only had 180 million square meters of energy-efficient housing, far from meeting the requirements of energy conservation. The new housing will take energy saving measures from the aspects of planning, design, the application of related materials and equipment, so as to improve the quality of the house, promote the use of new materials, new technology, new technology, and promote the upgrading of the building material industry. So to have a higher level of insulation materials and insulation technology, XPS extrusion plate to cater for this trend, the face will be a huge potential market. |
