The hottest textile and building materials for Sha

Textile construction materials of Shanghai WorldExpo are the main beam of the Expo. "The venue building of Shanghai WorldExpo is the biggest highlight of this WorldExpo, which embodies the design concept of 'better city, better life'." Dr. tangshifang, deputy director of the technical office of the Bureau of Shanghai WorldExpo coordination, said with emotion in an interview with this newspaper

reflect the new characteristics of architecture

among the visitors to the WorldExpo, many came with the desire to see the world without going abroad. In fact, the first thing they came into contact with was the unique buildings of various countries in the Expo Park, which reflected the face of a country and city. Given that China is the largest export market of U.S. waste, many countries have introduced the most advanced building materials and technologies into the venue buildings of various countries in this WorldExpo. The industrial textile used in it has decided that its loading speed products add a lot of color to the venue buildings of the WorldExpo because of its mechanical structure and hydraulic loading principle

Tang Shifang introduced the advanced design scheme of the German Pavilion and the Japanese pavilion and the application of industrial textiles in the pavilion. He said that the main curtain wall of the German Pavilion is a special textile material, and the surface is coated with a layer of fluorescent agent, which plays a role in reflecting sunlight and reducing the energy consumption of air conditioning in the pavilion. This new textile material is light, breathable and recyclable. It can be removed after the Expo and made into handbags. In addition, this new material can beautify the venues

he went on to say that the building materials of the Japanese National Pavilion played a great role in its venue construction. For example, the external wall of the venue uses materials coated with ETFE film, which greatly reduces the self weight of the entire venue and saves a lot of steel. The membrane material has two layers, and the middle is inflated to maintain a pressure of 250 PA. Under this film, there are solar panels to provide power for 50 52 Inch televisions in the venue

what is particularly mentioned is the "circulating breathing column" design of the venue, which is known as the "breathing organism". On the one hand, it can replace the steel support and reduce the steel consumption by 40%; On the one hand, it can ventilate and exhaust the dirty air in the museum, and extract the moist underground air to reduce the temperature of the venue. At the same time, it can also refract the sunlight and save lighting power consumption. It realizes the natural regulation of light, water and wind. The external light will transmit the natural light to the lower layer through the "circulating breathing column", so that the indoor space in the central part of the building can realize natural daylighting; When it rains, it increases at a rate of 20% every year. The breathing column will collect rainwater and sprinkle the collected rainwater on the roof, which not only cleans the roof, but also cools the building as a whole. The spilled water can also be recycled through this; The chimney of "circulating breathing column" can effectively form an updraft, send the cooled air below into the museum, reduce the temperature in the museum and reduce the air conditioning load

feel its architectural design style of "harmonious city" in the German Pavilion. The German Pavilion is the largest one that has participated in the previous WorldExpo, and it is designed and constructed by schkar Architectural Design Co., Ltd. in Munich, Germany. This outer and inner building is like a three-dimensional sculpture that can enter and break the inner and outer boundaries. The whole construction area is 6000 square meters, and the exhibition area is 3600 square meters. Among them, the building covers an area of 12000 square meters and can accommodate 45000 visitors every day. Although the manager Kongdi of the reception department of the German Pavilion did not disclose what textile materials were used in the wall of the membrane building of the German Pavilion, it can be learned from the information she gave that this silver fabric is a special membrane, which can reduce ultraviolet radiation during the day and can be used as a lighting carrier at night to provide convenience for venue lighting. Moreover, this transparent film can change different scenes at different times and weather conditions

the Japan Pavilion is like a "Purple cocoon", which is convenient for disassembly after the WorldExpo. Instead of using steel to lay the foundation, it is built with lightweight building materials, recyclable materials, etc. Its facade building membrane material is called "membrane that can generate electricity and breathe". The outer wall of the whole venue is covered with membrane materials of different shapes, which has the maximum light transmittance. The expanded pillow shaped membrane is internally powered by amorphous solar cells, which remove the self weight of the spring and turn it into internal power generation, The external structure is not only "energy-saving", but also "energy creation"; the internal use of the latest technologies, such as circular breathing channels, makes the maximum use of natural resources such as light, water, air and so on.
