The Tokyo Olympics is in full swing, and for every Olympics, there will be many sparkling sports talents, and there will also be many new material applications to help them continue to break through the limits of the human body.
What new chemical materials have been used in the Tokyo Olympics in Japan? Let's take a look together.
At the 19th Olympic Games held in Mexico in 1968, the polyurethane plastic track was officially adopted.
Since then, the International Olympic Committee has officially designated the plastic track as one of the prerequisites for international competitions.
The plastic track is clean and beautiful, easy to maintain, and not affected by the weather. Moreover, the elasticity of the plastic can increase the rebounding force of the athlete when kicking the ground, ensuring the elevated position of the knee, thereby increasing the stride.
The Olympic Organizing Committee has collected nearly 400,000 bottles of washing powder in large retailers and schools across Japan. These household plastics are recycled into filaments and 3D printing is used to make 98 Olympic podiums.
It is said that this is the first time in the history of the Olympic and Paralympic Games that the public has participated in the collection of waste plastics to make a podium.
The Tokyo Olympic venues use polyether polyols (used to produce low-density to high-density foams as sealants) to fill the gaps between building materials, reduce the risk of deformation caused by concrete expansion at high temperatures, and keep the stadiums safe and stable.
The high-durability acrylic emulsion adhesive used for interior wall coatings in the Tokyo Olympic venues has excellent long-term durability and substrate adhesion.
Elastomer wall coatings can provide solutions for the exterior, with excellent dirt resistance and a balance of mechanical properties. In water-based coating systems, glycol ethers can meet the requirements of low volatile organic compounds (VOC) while optimizing the stability and performance of the coating.
The torch platform uses clean energy hydrogen as fuel. Inspired by Mount Fuji, the concept is "Under the sun, all beings are equal, and everyone has energy".
Designed as a sphere that can bloom and unfold, just like a plant sprouts and a flower blooms, it symbolizes energy and vitality.
The main stadium of the Tokyo Olympics-the New National Stadium. After careful design, the gymnasium is composed of an open view from above the milky white sheet of the roof and the all-steel structure of the stands.
From the point of view of materials, the unique and feather-like undulating roof and the pillars distributed at equal intervals around the gymnasium adopt an all-steel structure, and part of the stadium awning is made of solar panels.
The material of the sunshade roof is made of PC sun panels, the purpose is to provide a venue with shelter function for the people watching the ceremony in the stands.
At the same time, the gymnasium has the following advantages when choosing materials such as PC sunshine board :
(1) Connection PC sun panels can be close by, are unlikely to cause leakage, can fully meet the project requirements of the basic functions of the roof, solar panels, and easy processing and construction, will help shorten the construction period and reduce the cost ;
(2) The cold bending characteristics of the solar panels are very helpful in shaping the roof curve ;
(3) The sunshine board can be recycled and reused and is an excellent environmentally friendly material.
On the whole, the application of sunlight panels meets the high-performance requirements of the gymnasium for thermal insulation and sealing of the enclosure structure, shields the huge indoor steel structure components, and achieves the perfect unity of specific use requirements and economy.
While watching the Olympics, we can always experience the power of craftsmen. This not only refers to the perseverance of the athletes but also the buildings and materials that silently support the entire Olympics.
Through the introduction of this issue, I believe that everyone has an understanding of the building materials used in the Tokyo Olympics, and many of them are environmentally friendly.
Nowadays, people are paying more and more attention to the topic of environmental protection, and the corresponding environmental protection office appliances are also used in the office. Next, I will introduce some high-tech environmental protection appliances in the office!

You can pay attention to the trend of new chemical materials while paying attention to the Olympic Games. These materials are not only "new", they also have epoch-making significance. The game is still going on, Chinese athletes come on! We are proud of you!
