Green energy saving building materials, plastic pipe market or the development of spring
In January 2013, the state council general office issued the "green action plan for energy saving building materials, to develop green building energy saving, environmental protection, low carbon," twelfth five-year "period to complete the new green building 1 billion square meters; By the end of 2015, 20 percent of new buildings in urban areas meet the requirements of green building standards. In 2020, the proportion of green buildings in China's cities will increase to 50%. This marks the development of green buildings in our country to the national strategic height.
Building energy saving must use building thermal insulation material, heat insulation paint, sealant adhesive; The materials need to be used for the steel products of the plastic materials. Environmental protection should use water - based paint, photovoltaic material and so on. According to the goal of the green building action plan, people in the industry estimate that the green building can drive the market demand of 2 trillion yuan of green building materials in the near future. Among them, chemical building materials will achieve breakthrough in technical and policy matching, market cake is huge.
With the acceleration of the green building promotion process, plastic materials, including plastic doors and Windows and plastic pipes, will enter a stable and high growth period.
According to the plastic door and window development expert feng's introduction, the biggest advantage of PVC profile is energy saving. In terms of the energy consumption of materials, the production of PVC doors and Windows of 1 square meter is only 1/8 of the steel and 1/16 of aluminum. And PVC materials can be recycled and reused, without re-smelting, ingots and very little energy consumption. This is very beneficial to promote in green building.
Feng said plastic doors and Windows have a performance advantage. PVC doors and Windows are better than traditional wood doors and Windows. It is cheaper than aluminum alloy doors and Windows, which is conducive to building energy saving. As the state attaches importance to building energy conservation, plastic doors and Windows as the green building materials will face development opportunities. He stressed that at present our country plastic building materials market competition is intense, many enterprises to reduce costs, ignore the product quality and performance, he suggested that enterprises should take full advantage of green building to promote this opportunity, improve the technology content, strict technical standards, the development of qualified products.
Plastic piping also has a distinct advantage in saving energy. It is understood that the production energy consumption of plastic pipe is only a quarter of the traditional metal pipes such as steel pipe and cast iron pipe, and the energy consumption of the pipe network is much smaller than that of traditional metal pipes. In addition, plastic pipes rarely produce waste during production. Wang zhanjie, secretary general of the plastic piping professional committee of the China plastics processing industry association, believes that the rapid development of green building in the future will bring another boom to the plastic piping industry.
The energy consumption of buildings accounts for about 30% of the total energy consumption of the whole society. In high-energy buildings, the heat loss of walls and external Windows accounts for 85% of the total heat loss of buildings. To realize building energy conservation, it is necessary to improve the insulation performance of external walls. The external insulation material of polyurethane exterior wall is very good for construction and has a wide market in green building.
"Polyurethane has a light weight, low thermal conductivity, good heat resistance, aging resistance, burn easily with other substrate bonding, don't produce the excellent performance, such as drop especially good heat insulation and flame retardancy, is in the European and American countries are widely used in building thermal insulation materials, but the proportion is less than 10%, is applied in our country has great application in green building promotion space." Li jianbo, deputy secretary-general of the China polyurethane industry association, told China chemical news.
Wei hua, general manager of nanjing hongbao lixin material co., LTD., also believes that green building is a rare development opportunity for polyurethane wall insulation materials. On the one hand, building energy efficiency is the hard index to evaluate whether buildings belong to green buildings. This requires the building to be used in the heat preservation material, to ensure the performance of the material, the polyurethane material with the lowest thermal conductivity has the advantage of the unique advantage. Green buildings, on the other hand, require a life-cycle concept. Polyurethane insulation material can be used for a long time to ensure the thermal insulation effect.
China polyurethane industry association secretary-general chang-chun zhu said that the government under the impetus of the existing building energy-saving renovation project, pu heat preservation material demand increased significantly in recent years, the market share increased substantially. "Much starker choices-and graver consequences-in" period, our country the comprehensive promotion of green building, reduce the energy consumption of the standard requirement will be higher, the proportion of polyurethane application in the field of construction is expected to increase sharply, especially the price advantages, good flame retardant properties of new pu heat preservation material.
The production of building coatings in China accounts for about 45.6% of total coating production. The high standard and high standard of green building, whether the quantity of paint, or quality, will be improved greatly, so as to promote the development of green building coatings industry.
Miit raw materials department deputy director Pan Aihua pointed out that the connotation of green architectural coatings, including water, low VOC, low heavy metal content, environmental protection concept, also related to building energy efficiency, green concept such as life cycle.
In the aspect of building energy conservation, the exterior wall paint and glass coating with heat and heat reflection can help buildings block some heat during the hot season. According to liu guojie, an expert of China paint industry association, the outer layer of the exterior wall of the building has the characteristics of thermal insulation in the building insulation. For the renovation of existing buildings, the construction link can be reduced if the insulation coating system is adopted, and the cost is greatly reduced. In addition, the new type of exterior wall paint can replace the city's large amount of light screen glass wall, reducing light pollution.
The green building area has doubled in size, providing a new world for the chemical products with energy saving and heat preservation function. With the concept of green building, the application of plastic building materials for the use of Windows and doors for several decades will enter a stable and high growth period. In China, there are less than 10 percent of the polyurethane building insulation materials that are widely used in Europe and the United States. New green paint with thermal insulation function will also welcome spring.
Domestic economic growth is slowing year by year, and some traditional downstream markets have insufficient demand, but green construction is different. In the past five years, the total area of green building in China has been developing at a rate of double every year for the past five years. By the end of 2014, the total area of green building in China has been nearly 163 million square meters. China's building energy consumption accounts for a third of the total energy consumption of society, promoting green buildings, and its core content is to realize the comprehensive energy conservation and emission reduction of buildings. As the area of the green building to further expand, plastic materials, pu heat preservation material as well as the new green energy-saving building materials, such as energy saving effect obvious chemical products will usher in new opportunities, a green revolution has come from the bottom up.
