Recently, the "2011 China Guizhou housing and Urban Rural Construction Technology Expo" (hereinafter referred to as the "science and Technology Expo") hosted by the Department of housing and urban rural development of Guizhou Province was held in Guiyang. More than 200 enterprises from all over the country, including building energy-saving products and technology enterprises, new building materials, decorative materials and home decoration enterprises, collectively displayed new technologies, new equipment There are more than 1000 kinds of new products and processes

during the exhibition, the Department of housing and urban rural development of Guizhou Province also held a meeting on energy conservation and science and technology in the construction field of Guizhou Province, summarizing the energy conservation and science and technology work in the construction field of Guizhou Province during the "Eleventh Five Year Plan", and deploying the energy conservation and science and technology work in the construction field in the "Twelfth Five Year Plan" and "201". The outline of the 12th Five year plan puts forward that the building materials industry "focuses on the development of new materials such as photovoltaic glass, ultra-thin substrate glass, special glass fiber, special ceramics, and supports the construction of production lines for the collaborative disposal of urban domestic waste and sludge in cement kilns and demonstration lines for the comprehensive utilization of construction waste". New building materials have undoubtedly become a new highlight of the development of the building materials industry

at the science and Technology Expo, it can be seen that the knife made of special ceramics is second only to diamond in hardness and does not leave stains when cutting, but its weight is only 1/3 of that of metal knife, and its wear resistance is 60 times that of metal knife; The compressed natural gas (CNG) cylinder made of special glass fiber is 57% lighter than the traditional cylinder of the same specification, which greatly improves the load capacity of new energy vehicles; There are also some new building materials, such as recyclable steel strip reinforced polyethylene spiral bellows, which have attracted much attention

In this regard, Qiao Longde, President of China Building Materials Federation, pointed out that the country is accelerating the transformation of development mode, and the building materials industry is also using its brains to seek new changes. Only by developing and manufacturing new products can there be a market and profits in the context of structural adjustment; Only by creating new ways of production management can we survive and develop in the context of energy conservation and emission reduction

"new" building materials industry in the 12th Five Year Plan, where does the "new" come from

develop new raw materials, improve new processes, and improve the resource utilization rate of "old products". For example, the project of collaborative disposal of municipal solid waste, sludge production lines and construction waste in cement kilns can save energy resources and improve the urban environment while normal production, which can be described as killing many birds with one stone

add new products and extend the market space of "old industrial chain". For example, cement is a traditional building material, a raw material product with large production capacity and small profit space. However, by extending the industrial chain of cement and developing commercial concrete and cement products, the production cost is almost unchanged, but the profit can be doubled

develop new materials to meet the development needs of emerging industries. Photovoltaic glass, ultra-thin substrate glass, special glass fiber and special ceramics mentioned in the outline of the 12th Five Year Plan are all new materials. Different from traditional building materials serving infrastructure construction, new materials are widely used in transportation, military and national defense, electronic information, new energy and other fields. For example, computer LCD screens and screens use ultra-thin substrate glass, and the raw materials of high-power wind blades are special glass fibers. These new application fields are in a period of rapid growth, which are the investment highlights and consumption hotspots supported or actively guided by the state, and the building materials industry has great prospects

compared with traditional building materials, "new" building materials apply new technologies, extend the industrial chain, and cross industry boundaries. Therefore, the market demand is wider, the profit is higher, the energy consumption is lower, and the market anti risk ability is stronger. At present, enterprises develop "new" building materials not only because they feel external pressure, but also because their motivation has been improved

the market demand for "new" building materials is more prosperous. In recent years, the development speed of new products and materials has far exceeded that of traditional building materials. In 2010, the growth rate of added value of China's cement manufacturing industry was 13.1%, while that of cement products was 34.8%; The growth rate of added value of flat glass industry was 16%, while that of technical glass was 31.7%, and that of glass fiber and products was 46.3%

the industry contribution of "new" building materials is higher. In 2006, the added value of technical glass manufacturing industry just exceeded that of flat glass. By 2008, the added value of technical glass manufacturing industry has been twice that of flat glass. At present, the contribution of new products and materials to the growth of building materials industry has been equal to that of traditional building materials

"new" building materials are more competitive. In 2010, due to the increase in the export proportion of new products and new materials, the export volume of China's glass industry fell. "Nagori aftershock" is the tableware made of new materials with plastic formability and ceramic texture. 60% of the inorganic flame-retardant materials in the United States, Japan and other countries consumed more than 60%, but the export volume increased by 30%

the unit energy consumption of "new" building materials is lower. In 2010, the added value of the new products and materials industry accounted for 43.1% of the whole industry, and its energy consumption accounted for only 6.5% of the whole industry, which greatly diluted the unit energy consumption of the building materials industry, making a great contribution to the 52.6% reduction in the unit energy consumption of the building materials industry at the end of the eleventh five year plan compared with the end of the tenth five year plan
