The unified "benefit" of the Expo site

There are many bright spots and scenic spots in the Expo, but what attracts your attention and impresses you is the uniforms inside and outside the Expo venues, and the strange and magnificent buildings except the venues. Whether it is Expo officials, service personnel, volunteers, security guards or news media workers, they all wear different styles and specially customized clothes. These garments reflect the scientific and technological progress of textiles and garments in China in design and function.

36 1 degree (China) Co., Ltd. provided10.3 million sets of equipment for the urban volunteers of the Shanghai World Expo, among which the clothing fabric was specially treated, which was windproof, waterproof, warm, light and comfortable, and had strong outdoor functionality. According to the working characteristics of media reporters, Shanghai Metersbonwe Bang Wei Bang Wei Clothing Co., Ltd. specially designed a breathable and rain-proof garment with large reflective strips on it. Xtep provided 80,000 sets of special clothes for the volunteers of the Expo site, and used natural and environmentally-friendly cotton materials in fabric selection; In the production process, high-tech knitting technology is adopted to meet the dual requirements of aesthetics and comfort of clothing. Because the World Expo spans many seasons and the weather is changeable, volunteers' clothes are specially designed: the length of sleeves can be changed at will, and the length of pants can be "stretched" freely. In addition, the waterproof, windproof and cold-proof functions of the clothing have also been strengthened. The fabric of volunteer clothing also has the effect of instantaneous cooling. When the fabric touches the skin, it can produce an instant cooling 1~2℃ cold feeling. If exposed to the sun for a long time, the temperature difference of cold sensation can reach 3~5℃.

Textile science and technology display their talents

The brilliance of industrial textiles can be seen everywhere in the landmark buildings of the Expo site, where the scientific and technological achievements of industrial textiles are condensed. Around the Expo Center, the world's largest continuous cable-membrane structure, which is spliced by white membrane cloth connecting the China National Pavilion and the theme pavilion, is like handfuls of huge umbrellas to shelter tourists from the wind and rain, and also like pieces of white clouds, which constitutes a unique and beautiful landscape in the park. This kind of membrane structure material is generally based on high-strength polyester industrial fiber or glass fiber woven fabric, and both sides are compounded or coated with polymer materials such as polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF) or polytetrafluoroethylene (PTFE). It is the first choice for large-span buildings in the world today, with the advantages of light structure, large span, quick installation, low cost, fire resistance and flame retardancy, and high safety. According to the reporter's understanding, because there is still a certain gap between the membrane structure materials produced in China and those produced abroad, most of the membrane structure materials in the Expo site are imported.

The carbon fiber bicycle in the Petroleum Museum weighs only about 4 kilograms. Carbon fiber has high strength and light weight, and its specific gravity is less than a quarter of that of steel, but its tensile strength is 7-9 times that of steel. It is a new dual-purpose material in Zhong Junmin, mainly used in aviation, chemical industry, medicine and other fields.

In the Petroleum Pavilion located in Zone D of the Expo Park, the materials of the external wall, the clothing, chemical fiber products and industrial textiles in the pavilion all gather the achievements of textile science and technology. In the "Wear Oil" exhibition area, the wax figures wearing various costumes at the entrance are lifelike, and the process of oil turning into clothes is constantly played on the big screen. The exhibition hall of petroleum chemical fiber products displays the spacesuit and special police uniform independently developed by China. Those spacesuits and helmets with the characteristics of heat insulation, earthquake prevention, radiation protection, shock absorption and light weight represent the highest scientific and technological level of textiles and garments in China; Special police uniforms are made of non-toxic, flame-retardant and breathable fabrics, which have the functions of high temperature resistance, impact resistance and bulletproof. The parachute of the return cabin is made of high strength and high modulus textile materials; Chemical fiber products such as carbon fiber bicycles have gradually entered people's lives ... These objects vividly show the course of China becoming a world textile power after decades of efforts.

As the greenest and most environmentally friendly material in the world, soybean fiber has entered the World Expo. The low-carbon environmental protection materials used in Austrian National Pavilion and Sichuan Pavilion in China all come from soybean fiber materials provided by Xiu Yuan Baby Clothing Company in China.

The high-tech material "optical fiber cloth" developed by Taiwan Province Guandehong Technology Co., Ltd. is a high-tech product combining textile and photoelectric technology. It once made its mark at the Spring Festival Gala and made its debut at the World Expo this time. It is understood that this kind of fabric is made of ultra-fine optical fiber, which is woven into a plane fabric by using foreign fiber yarns through the traditional textile processing, and can emit light as a whole after being electrified. There is no difference between ordinary fabrics during the day, but it can emit colorful light at night or in the dark.

Intelligent Transportation: The simpler the line, the closer the heart is.

Presentation of dreams

Zero-emission electric vehicles have become the protagonists on the road, and automobile charging stations will be all over the streets of the city;

Disabled people, such as children, the elderly and even the blind, can drive to the places they want at any time;

The car lifting system can make the car stop directly on the surface of the building, which greatly expands the urban space;

……

This is the theme movie "2030, OK! "SAIC General Motors Exhibition Hall. The urban traffic scene in 2030 is shown in the picture. Electrification, vehicle networking and autonomous driving technology constitute the beautiful scenery of urban intelligent transportation in the future. This intelligent transportation system will make driving easy, interesting and fashionable. Autopilot completely liberates people's hands and has more time to spend in the car. With the help of wireless information system, cars can also become people's offices.

"The simpler the line, the closer the heart." Because intelligent transportation bid farewell to traffic jams, people's lives are more efficient and they can leave more time to more important people. So people's hearts are closer and society is more harmonious.

Continuation of reality

In the SAIC General Motors Exhibition Hall, two "treasures of the town hall" independently developed by SAIC were exhibited: the negative emission concept car "Leaf" and the electric networking concept car "EN-V".

As the name implies, the big leaf on the roof is a wonderful photoelectric converter, which simulates the photosynthesis of leaves in nature and converts solar energy into electric energy. Whether it is cloudy or rainy, "leaves" can absorb solar energy and maximize the use of energy. "EN-V" realizes the compatibility of manual driving and automatic driving. It can automatically choose the best driving route through the analysis of real-time traffic information, thus alleviating traffic jams. It can also perceive the surrounding environment and make quick adjustments when encountering obstacles or changing driving conditions. This information exchange with other vehicles and road infrastructure can greatly reduce the occurrence of traffic accidents.

Smart Grid: Intelligent "Power Housekeeper"

Presentation of dreams

In the State Grid Pavilion, there is a beautiful blueprint for the future smart grid-

Just press a button, you can control the switch of household appliances such as air conditioners and microwave ovens; Every household can become a "trading station" for electric energy, and it can also generate electricity while using electricity. If wind and solar power generation equipment is installed at home, it can be "uploaded" to the public power grid after use. Users can see the real-time electricity consumption through smart meters, including the electricity consumption of air conditioners, air purifiers and other electrical appliances, and make timely adjustments. ...

In short, the smart grid is like an intelligent "electricity housekeeper", managing everything related to electricity for you efficiently.

Continuation of reality

There is a smart grid demonstration area in Lefuting Community, Eshan Road, Pudong, Shanghai. At present, more than 65,438+000 households have enjoyed the convenience brought by smart grid. Only one terminal is needed to control all household appliances, and remote control is not difficult. Through smart meters, we can not only know the household electricity consumption and the electricity consumption of each electrical appliance at different times of the day at a glance, but also help users to use electricity more economically according to the different electricity prices during peak and valley periods.

According to the person in charge of State Grid, the development of smart grid in China will be divided into three stages: from 2009 to 20 10, the planning pilot stage; The period from 20 1 1 to 20 15 is a comprehensive construction stage, initially forming a smart grid operation control and interactive service system; From 20 16 to 2020, a unified and strong smart grid will be built in an all-round way.

Some experts have analyzed that the Shanghai World Expo may be the one with the highest scientific and technological content in previous world expositions, and the concepts of ecological technology, light health, solar energy and green energy conservation will be fully displayed at the World Expo. Among them, China Aerospace Science and Technology Corporation's solar photovoltaic technology and power lithium battery technology will all show their talents.

The megawatt photovoltaic power station of the Expo Center, which was jointly built by Shanghai Aerospace Automobile Electromechanical Co., Ltd., Shanghai Solar Engineering Technology Research Center and Shanghai Solar Technology Co., Ltd. affiliated to the Eighth Academy, has been completed, fully embodying the harmony and unity of solar energy, architecture and green technology. The total installed capacity of the power station is 1.004 MW, and the annual power generation after operation can reach 1 10,000 kWh, which can reduce carbon dioxide emissions by more than 900 tons and will contribute to the "low-carbon Expo".

"In the design process of megawatt photovoltaic power station, we considered the optimization of power generation efficiency of photovoltaic power station and the unity of architectural aesthetics as a whole, and adopted various ways such as monocrystalline silicon photovoltaic modules and green intervals on the plane, which reflected the meaning of green energy contained in solar energy. At the same time, double-sided glass photovoltaic sunshade module is adopted on a large scale to achieve the effect of beauty and energy saving. This is the first time in China. " The person in charge told the reporter.

The first batch of aerospace power lithium battery car prototypes developed by No.8 Institute11will be put into use during the Shanghai World Expo, mainly for VIPs and pure electric vehicles. As one of the core components of new energy vehicles, power lithium battery is a typical integrated product of military products, which "grafts" the stability, durability, reliability and durability of spacecraft power supply to new energy vehicles and uses space technology to help "Green Expo".

It is also known that Beijing Aerospace Times Optoelectronic Technology Co., Ltd., which belongs to the Ninth Academy, has also provided nine sets of all-fiber electronic current transformers for the World Expo to serve the first intelligent substation of the World Expo.
