  • Detail

The Ministry of housing and urban rural development and the Ministry of science and technology vigorously promote new energy-saving building materials

in order to promote the transformation of scientific and technological achievements and promote building energy conservation, the Ministry of housing and urban rural development and the Ministry of science and technology jointly issued the catalogue of promotion of energy-saving transformation technologies for existing buildings, including a number of building materials such as solar energy technology, heating technology, door and window materials, wall materials, chemical building materials, etc. It can be seen that the development of new energy-saving building materials will provide strong support for building energy conservation and lay a foundation for the successful completion of China's energy conservation and emission reduction goals

Qiu Baoxing, Vice Minister of the Ministry of housing and urban rural development, said at the press conference held by the State Council office that China's energy consumption per unit building area is times that of developed countries, causing a heavy energy burden and serious environmental pollution to the society. China should take the path of sustainable development, and it is urgent to develop energy-saving and green buildings. He also pointed out that China's building energy-saving potential. For example, the film produced by the PP film blowing machine is suitable for various supermarket shopping bags, mushroom bags and other bags with high hardness and low requirements for stretch and brightness. Building energy-saving has become a key factor affecting China's strategic decision-making for sustainable energy development

in this regard, xuyongmo, vice president of China Building Materials Federation, pointed out that the development of the construction industry, especially the development of building energy conservation, needs the support of the building materials industry. He said that the development of green energy-saving buildings (low-carbon buildings), the promotion of housing industrialization, the improvement of building service life, and the improvement of the aesthetic level and cultural characteristics of architectural design are closely related to the development of the building materials industry. The development and progress of the building materials industry provide the possibility for the above work. Therefore, in the context of energy conservation and emission reduction, the construction industry has great demand for the development of the building materials industry, including new wall materials that meet the requirements of building energy conservation, green fire-proof durable composite insulation wall structure system, residential industrialization material component and function integration technology, evaluation of green building materials in green building applications, harmless disposal and resource utilization of urban waste, etc

The building materials industry has a long way to go in terms of energy conservation and emission reduction. Xu Yongmo said that in recent years, the development of China's building materials industry has made remarkable achievements and major progress. Many advanced technologies and equipment in the industry have approached or reached the international advanced level. Major progress has been made in the adjustment of the industry's main technical structure, such as the proportion of new dry cement process is more than 70%, and the proportion of float glass is more than 80%

under the guidance of energy conservation and emission reduction policies, the building materials industry has made significant progress towards "two oriented" and environmental protection industries in the demand of the building energy conservation market. According to statistics, at present, more than 700million tons of solid wastes are used in the building materials industry (cement, concrete, wall materials and other industries); Low temperature waste heat power generation has been promoted (cement and glass industries); The technology of disposing urban sludge, industrial hazardous waste and domestic waste has been gradually popularized (cement industry). Moreover, the building materials industry has become a pillar industry of the national economy, especially the basic raw materials industry, the main materials of energy-saving buildings (main structure, enclosure structure, functional materials), the new energy industry, the supporting materials of the new material industry (wind power blades and also promote innovation and innovation films, solar glass), etc., which occupy a pivotal position in the national economy. However, serious overcapacity, backward material and product technology, poor enterprise technological innovation ability, backward industrial structure, low production concentration of standard product industry and backward development mode are still the bottlenecks that perplex the future development of the building materials industry

building energy conservation gives birth to new building materials

now, low-carbon life has become a social consensus, and new building materials have a broad future. In this regard, experts said that the promotion of energy-efficient building materials has just started. Only when more new building materials manufacturing enterprises become the main force in the development of housing industrialization, the goal of 65% energy saving in new buildings in China can be achieved as soon as possible

building energy conservation mainly improves the thermal resistance and airtightness of the enclosure structure from the three aspects of external walls, roofs, doors and windows, so as to achieve the purpose of saving the energy consumption of the blow molded film of the building, which can also be used as a variety of utilization technologies such as food preservation. Industry experts believe that at present, we should focus on the development of various energy-saving walls, roofs, doors and windows applicable to different climatic conditions, especially the external wall insulation technology and high-efficiency energy-saving doors and windows technology, and develop various new high-efficiency energy-saving wall materials, thermal insulation materials and high-performance building glass. Based on the promotion of these aspects, there will be a broad market demand for four categories of building materials in the future, including new wall materials, thermal insulation materials, low E glass and photoelectric glass

at present, new energy-saving building materials mainly include new wall materials, chemical building materials, new thermal insulation materials, building decoration materials, etc. Although there is market demand, the development of new energy-saving building materials in China is still difficult due to cost, market constraints and technical barriers

at this stage, the competition of most new building materials enterprises in China is mainly concentrated in the middle and low-end products. There are few products with high technical content, and the competition in the high-end field is not fierce. Among them, the most obvious is the plastic pipe and door and window industry. At present, the medium and low-end products in China have experienced overcapacity and the market can achieve sustainable development and slow down growth. Domestic plastic water pipes and pipe fittings are mostly general-purpose products, and the production of pipes and pipe fittings with high use requirements and high value-added content is less, which greatly limits their market application, while the application of plastic pipes in high-end fields is only in its infancy. The main reason is that the industry lacks scientific and technological investment and technological innovation in energy and resources conservation, which has affected the improvement of the overall level of the industry

at present, in the production and sales of plastic building materials such as wall internal and external insulation boards and roof waterproof materials with high profit margin, the production enterprises have short-sighted behavior of being eager for quick success and instant benefit, which has buried hidden dangers for the development of the industry. In addition, building energy-saving materials such as cement hollow bricks, which replace clay solid bricks and clay hollow bricks, have been widely promoted. However, such products also have problems affecting project quality, such as insufficient strength and large construction differences

in addition, the imperfect supporting policies, the problems of low threshold, low concentration and disordered market competition in the development of the building materials industry, and the pressure of enterprises to transfer to high-tech and high-end markets are all important reasons why new energy-saving building materials are difficult to develop rapidly in a short time

at the world climate conference held in 2009, China made a solemn commitment to the world: by 2020, China's sulfur dioxide emissions per unit of GDP will be 40% 45% lower than that in 2005. At present, China's building energy consumption accounts for about 40% of the total energy consumption of the whole society. In order to fulfill China's commitment to the world, as a major energy consumer, building energy conservation is imminent, which also brings opportunities to the development of new building materials. It can be predicted that the development potential of green energy-saving building materials with energy-saving effect will be unlimited. At the same time, through the use of new building materials, building energy conservation will also achieve remarkable results
