Existing status and development trend of extruded insulation boardExisting status and development trend of extruded insulation board
Extruded insulation board is widely used, suitable for building roof insulation, steel structure roof, building wall insulation, building floor moisturizing, square floor, ground frost heave control, central air conditioning ventilation duct, airport runway insulation, high-speed railway Roadbed etc.
Plastic insulation boards are particularly prominent in the insulation industry and the construction industry:
In recent years, the extruded polystyrene board has been widely used in the world. This new material has a closed-cell structure inside, which has excellent and long-lasting insulation performance, and strong water repellency to prevent water vapor penetration. Capability, fairly high compressive strength, easy processing, and easy installation are the world's recognized ideal insulation materials for inverted roofs. The water absorption rate 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 only absorb a small amount of water in the initial stage after being immersed in water, and then no longer absorbs water. This property makes it have excellent insulation performance and last forever. This feature is important for inverted insulation roofs. . In addition, the water vapor permeability of extruded polystyrene is 2 to 4 times lower than that of expanded polystyrene. Therefore, this insulation material can not only prevent the penetration of rainwater but also prevent the penetration of moisture, thereby avoiding the inside of the material The accumulation of water due to condensation is beyond the reach of most insulation materials.
The energy policy of the Chinese government is to "emphasize development and conservation" and put conservation first. Saving energy is still a strategic point of China's energy industry. In 1986, the Ministry of Construction promulgated the "Civil Building Energy-Saving Design Standards", and then further improved the standard indicators. Before the implementation of building energy efficiency standards, the cumulative area of residential construction in my country over the past year was nearly 8 billion square meters. Since 2000, the energy-saving renovation work of the original buildings with poor thermal environment or large energy consumption in the heating area has begun. In 2005, key cities and towns began to carry out building thermal environment and energy-saving renovation. XPS is very attractive in energy-saving houses due to its excellent performances such as low thermal conductivity, light weight, high strength, waterproof, impermeable, and easy construction.
During the Tenth Five-Year Plan period, there will be a huge development in our residential construction. At present, the amount of urban buildings is about 7 billion square meters, of which more than 4 billion square meters are residential. In the next ten years, 5.7 billion square meters of houses will be built in urban and rural areas, including 2.7 billion 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 built 180 million square meters of energy-saving houses, which was far from meeting the energy-saving requirements. New housing will adopt energy-saving measures from planning, design, application of related materials and equipment, improve the quality of housing, and advocate the use of new materials, new technologies, new processes, and promote the upgrading of the building materials industry. Therefore, to have a higher level of thermal insulation materials and thermal insulation technology, XPS extruded insulation board meets this development trend, facing a huge potential market.If you want to know more about it please do not hesitate to contact me.
