On February 20, the 2022 Beijing Winter Olympics came to a successful conclusion, and "One World, One Family" blossomed into the "City of Double Olympics"

In order to prevent the import and spread of the new crown pneumonia epidemic, the Beijing Winter Olympics Organizing Committee and the International Olympic Organizing Committee jointly formulated the "Beijing 2022 Winter Olympics and Winter Paralympic Games Epidemic Prevention Manual", requiring all overseas participants to enter China directly.
Closed-loop management system, and prepared sufficient anti-epidemic equipment and anti-epidemic materials within the closed loop
.

Air disinfection is an important link in blocking the spread of the virus
.

The novel coronavirus-killing purifier that appeared in the Beijing Winter Olympics news media venues and athlete's restaurant uses micro-mesoporous virus adsorption materials, which can efficiently adsorb and kill coronavirus, influenza A H1N1 virus,

AOP-KF solid alkali is a unique air purification material, which can release chlorine dioxide, effectively remove pathogenic microorganisms and gaseous pollutants such as formaldehyde in the air, and is non-toxic to animals, plants and humans
.

The air purifier with AOP-KF solid alkali appeared in the Capital Gymnasium, which holds two events of figure skating and short track speed skating at the same time, creating an operating room-level air environment for it

Masks are essential anti-epidemic supplies during the Winter Olympics
.

AOP-KF solid alkali is also used in the production of masks

At the closing ceremony of the Beijing Winter Olympics, the Olympic Organizing Committee also prepared customized N95 medical protective masks for the audience
.

The material used in N95 masks is melt-blown cloth made of polypropylene as the main raw material, which has good filterability, barrier properties, heat preservation and adsorption properties

In addition, the masks worn by athletes at the Beijing Winter Olympics when they received their prizes were made of nanofiber membranes
.

The nanofiber membrane adds a fine "protective net" to the mask, and the filtering effect of bacteria, viruses and various particles exceeds that of traditional meltblown non-woven fabrics, and it also has the functions of breathability, moisture conduction, anti-fog and green Environmentally friendly features

Full-time disinfection robots are also working silently in the Winter Olympics venues
.

The atomization and disinfection robots that perform all-round epidemic prevention tasks in the main media center of the Winter Olympics have attracted the attention of athletes at home and abroad

As one of the necessary materials for epidemic prevention, the hand sanitizer gel is made of special ethanol with the highest standard raw material, which is superior to the food quality grade, and can achieve the effect of removing aldehydes, avoiding and reducing the discomfort symptoms of users
.

In response to the temperature conditions of the Winter Olympics, this low-temperature disinfectant supplied by Shandong Xiaodao Disinfection Technology Co.

How to test the effectiveness of on-site epidemic prevention and killing at the Winter Olympics? Tsinghua University and other scientific research units have collaborated to develop a public space bioaerosol new coronavirus detection system
.
An aerosol collector is set up every 200 square meters in the stadium during the competition.
Using the principle of cyclone sampling, the particles in the air to be detected are collected into a sampling tube containing virus inactivation liquid.
The detection system completes automatic nucleic acid extraction and Amplification test, it only takes about 45 minutes to issue a test report, and the success rate of test samples is 100%, which ensures the safe, efficient and stable operation of the event
.

91 countries and regions, nearly 3,000 ice and snow athletes, 7 major events and 109 small events.
.
.
The Beijing Winter Olympics is the first global comprehensive sports event to be held as scheduled since the outbreak of the new crown pneumonia, creating a realization for more ice and snow athletes.
The stage of dreams
.
On this stage, veterans of the "Four Dynasties" such as Xu Mengtao, Qi Guangpu and Jia Zongyang lived up to expectations and achieved their dreams after more than ten years of hard work
.
As the main torch of the Beijing Winter Olympics is slowly extinguished, this 17-day international sports event has also drawn a successful conclusion.
In the current difficult time of global anti-epidemic, China, in the name of the Winter Olympics, is committed to the development of the Olympic movement.
Once again, China's plan is provided to inject confidence and strength into the world plagued by the epidemic
