[ Hot Focus on Chemical Machinery and Equipment Network ] 2022 Beijing Winter Olympics is in full swing, build a dream world of ice and snow! According to the spokesperson of the Beijing Winter Olympics Organizing Committee, the Beijing Winter Olympics is the Winter Olympics with the highest ratings so far, and the Chinese delegation has also created the best record since participating in the Winter Olympics.
Chemical machinery and equipment network hotspots focus on chemical machinery and equipmentWhen the Winter Olympics encounters Chinese culture, the world is shocked by the "water from the Yellow River", "Snow Ruyi" and "Ice Yuhuan"; when the Winter Olympics encounters low-carbon environmental protection, China's "green Olympics" practice Contributed new samples and wisdom to the world
.
"The green concept of the Beijing Winter Olympics has both Chinese and global significance
.
" That's right, the stories of these green Winter Olympics, found by Environmental Protection Online, also missed an "inconspicuous" green line-new material

" That's right, the stories of these green Winter Olympics, found by Environmental Protection Online, also missed an "inconspicuous" green line-new material
.
The display of the Green Olympics is not only placed in 100% green electricity, full sewage and waste treatment, green energy-saving buildings, new energy commuter vehicles, etc.
Visible places, the "nuances" show their intentions, and those green "Little" mind, you must know!

pure natural refrigerant
How can the ice and snow world be short of ice? It is reported that the national speed skating hall uses pure natural refrigerant - carbon dioxide, and adopts transcritical carbon dioxide direct cooling ice-making technology, which reduces the comprehensive energy consumption of the system by more than 30% and saves more than 2 million kWh of electricity, which is equivalent to about 120 Carbon emission reduction achieved by 10,000 trees
.
.
At the same time, the ice-making system refrigerant used in the snowmobile bobsleigh track is ammonia.
Based on the refrigeration system, a high-efficiency ammonia heat pump unit is also designed to recover the cooling waste heat generated by ice-making

(By the way, in terms of snowmaking, Genting Ski Park adopts an intelligent snowmaking system that meets the highest environmental protection standards and is more efficient and water-saving, which can save about 20% of water per cubic meter
.
The snow-making water source is also preferentially collected and stored.
Natural precipitation, surface runoff and other natural precipitation, built a perfect snowmelt water, rainwater recycling system

Graphene
In fact, environmentalists should not be unfamiliar with graphene, a new material.
After all, its development potential in membrane separation, energy storage, clean heating and other fields has begun to emerge
.
Graphene, known as the "King of New Materials", has also become a "flexible fabric electric heating material, modified aerogel, special fiber" and other products in this Winter Olympics

carbon fiber
Speaking of fiber, the carbon fiber used in the 2022 Beijing Winter Olympics must be focused
.
The Olympic torch that attracted absolute attention at the opening ceremony is made of carbon fiber composite materials, each bundle contains 12,000 carbon fiber filaments, which is the world's first! Its quality is only about 1/4 of steel, but its strength is 7-9 times that of steel.
Coupled with the "Feiyang" that uses hydrogen as fuel, it is no exaggeration to say that it is the epitome of the heavyweight under the concept of "green Olympics"

.
In addition, China Aerospace Science and Technology Corporation and China FAW Group have completed joint technical research and achieved a "zero" breakthrough in domestic snowmobiles
.
It is reported that the Chinese snowmobiles of the Beijing East Winter Olympics are all developed by China, and the body part adopts the domestic T800 carbon fiber composite material technology

There are also 3D printed carbon fiber speed skating shoes brought by the team of Professor Yang Jintian of Hebei University of Economics and Business for the Winter Olympic athletes, "compared with domestic high-end speed skating shoes, the weight is reduced by 4%, and the peel strength of the skates is increased by 7%", using carbon fiber high-performance composite materials, Achieved independent research and development
.
.
In addition, a high-performance ski helmet independently developed by the scientific research team of Dalian University of Technology is also a new material synthesized from three components: carbon fiber, glass fiber and elastomer
.
It is reported that the stiffness is increased by 4 times and the tensile strength is increased by 3 times

Cadmium Telluride Power Glass
Let's take a look at the confidence of all the green buildings in the Winter Olympics
.
For example, the team of Peng Shou, academician of the Chinese Academy of Engineering and chief engineer of China National Building Materials Group, independently developed cadmium telluride power generation glass.
As a new type of green building material, it has already achieved a number of application records of photovoltaic building integration demonstration projects

Recycled and degradable materials
① rPET fiber work clothes: made of rPET material (recycled beverage bottle material)
②Bio-based tableware: produced from corn, potato, crop straw, etc.
③Biodegradable plastic bags: Beijing Petroleum, a subsidiary of Sinopec, donated 100,000 Yijie brand degradable plastic bags to Zhangshanying Town, where the Yanqing competition area of the Beijing 2022 Winter Olympics is located
High performance low alloy corrosion resistant steel
Led by Professor Li Xiaogang of Beijing University of Science and Technology, and developed in cooperation with Shougang, it has overcome the serious corrosion problem, and the corrosion-resistant steel without coating anti-snow melting agent is safe and environmentally friendly
.
.
If you don't dig, you don't know, you will be shocked when you dig! The 2022 Beijing Winter Olympics really put a lot of thought into it, and the technological power behind it is even more commendable
.
A few days ago, according to the relevant person in charge of the Ministry of Science and Technology, the national key research and development plan has set up a key special project of "Science and Technology Winter Olympics", arranged and deployed 80 scientific research projects, and finally 212 technologies have been applied in the Beijing Winter Olympics
