Is there ice in the skating rink?
Under normal circumstances, there was ice in the skating rink. The ice skating rink in an international competition like the Winter Olympics was made of real ice. It was an artificially cooled ice rink. The temperature of the ice surface was controlled at-3 - 5 degrees Celsius and the thickness was 4 - 6 centimeters. The ice rink for the official competition would be carefully maintained and the quality of the ice would be good. A certain amount of milk would be added to the ice rink for international competitions to increase the toughness of the ice. In addition, there were also some non-real ice skating rinks, but most of the official skating rinks had real ice.

What kind of ice is the ice in the skating rink?
The ice in the skating rink mainly had the following conditions: 1. ** Early situation **: In the early days, ice was made from pure water, but there were problems with the use of pure water ice, such as scratches caused by blade friction, damage to the firmness of the ice surface, and so on. Later, there were ice-skating rinks that added milk to the water. The milk was oily and softer than ice after freezing. It increased the elasticity and crack resistance of the ice surface, reducing scratches and post-maintenance. As the ice-skating rink moved from outdoor to indoor, in order to solve the problems of aesthetics and meet the requirements of the competition, it would also use methods such as removing air bubbles in the ice layer, laying white ice paint, and adding milk to form a white, beautiful, safe and durable indoor ice-skating rink. However, some professional ice-skating rinks no longer used this "milk technology." 2. ** Current situation ** - ** indoor ice skating rink (real ice)**: Generally made of tap water. First, build an ice-skating rink of the required size, install a cooling pipe under the field and connect it to a large refrigerator outside. After injecting tap water, turn on the cooling equipment, and let the tap water cool down to below 0 degrees Celsius to condense into ice cubes, finally forming an ice surface. If the ice surface was used too many times and uneven scratches appeared, there would be specialized personnel to maintain it and add water to form a smooth ice surface. This method of making ice required a high capital cost, and the tickets were relatively expensive. - ** Ice-skating Rink **: The material is high-molecular-weight graphene, which is formed by the condensation of ethene and butadien under the effect of a catalyst. The average molecular weight is greater than 2 million. This material had good comprehensive properties and could work at-269 to +80 ° C for a long time. Its surface was smooth and the ground was flat. It was almost the same as the real ice experience and the cost was low, so most ice rinks would use it. 3. ** Ice rinks in large-scale events (such as the Winter Olympics)**: Advanced technology was used. For example, the 2022 Beijing Winter Olympics used carbon dioxide transcritical direct cooling technology. The ice maker first made a base ice 8 - 10 mm thick, then mixed the white paint with pure water, slowly and evenly sprayed it onto the ice surface, freezing the white paint to form a "milk" ice surface.(This is not really adding milk, but it has a similar effect.) The principle of this technology was similar to that of a refrigerator, but it could accurately control the temperature difference on the ice surface to not exceed 0.5 ° C. With pure water sprayed layer by layer on the ice surface, the ice surface would become stronger. The excess heat during the cooling process could also be used elsewhere, taking into account safety and environmental protection. 4. ** Ice surface treatment during ice filling **: In events such as figure skating, warm water of 40 ° C to 50 ° C is usually poured into the ice arena and frozen. This can melt the surface of the ice and then slowly cool it down to ensure that the ice layer is complete and smooth. Because using ice water would easily affect the fragility of the ice, which was not conducive to the game. Curling, on the other hand, would spray water onto the ice during the game, deliberately creating small particles to increase friction.

Ice skating rink painting
As for the ice skating rink painting, on the one hand, the children would use the ice surface as a drawing board to carry out creative painting. For example, the children of Zuncheng Public School in Xiaodian District of Taiyuan City would draw stick figures of ice skating, the Olympic rings, mascots, etc. on the ice skating rink. The different postures and serious appearances showed the children's rich imagination and creativity. On the other hand, there were many ice-skating rink-related paintings that existed in the form of simple strokes, such as ice skating rinks, people skating in the open-air ice skating rink in winter, ice skating rinks in color, ice skating rinks, pairs of ice skating, etc., covering the ice skating rink scene, people in the ice skating rink activities and many other images.

indoor ice skating rink
The indoor ice-skating rink was a place that provided ice sports. Some well-known indoor ice-skating rinks include: - The real ice skating rink in Guangzhou Guangming Square is located on the 7th floor of Guangming Square, No. 63 Xihu Road, Yuexiu District, Guangzhou City. The building area of the skating rink is about 5300 square meters, the practical area of the ice surface is 1800 square meters, and the height is 15 meters. It meets the international Olympic standards. It is the world's best ice quality and a multi-functional skating rink managed by a computer intelligent system. It can provide a variety of ice sports performances and competition functions. There are also public rest areas, storage areas, Ice sports school and many other supporting facilities. - The National Speed Skating Hall of the Beijing Winter Olympics, also known as the Ice Ribbon1, was located at No. 2, Lincui Road, Chaoyang District, Beijing City, near the Olympic Park. It was the only new ice competition venue for the 2022 Beijing Winter Olympics. Athletes from all over the world had broken Olympic records and world records many times here. It was the first speed skating venue in the history of the Winter Olympics to use carbon dioxide as a cooling agent. The temperature difference on the ice surface was uniform, so it was called the "fastest ice". The ice surface of the first phase of the track speed skating was about 6000 square meters. In addition to the ice surface of the track speed skating, there were two standard ice skating fields, which could be used for figure skating, short track speed skating, curling and ice skating training. There were service areas such as skating rental area, preparation area and rest area. - The International Trade Rink in Beijing was located in the central area of Beijing's central business district. It opened in 1999 and was the first real ice rink in Beijing to be built in a shopping mall. It covered an area of 1450 square meters and the ice surface area was 800 square meters. It could accommodate about 150 people at the same time. The temperature above the knee of the ice was 17 degrees Celsius. There were colorful activities, such as ice carnivals and Beijing opera ice parties. - Beijing's National Aquatics Center (Water Cube/Ice Cube) was completed in January 2008. During the 2022 Beijing Winter Olympics, the "Water Cube" was transformed into the "Ice Cube", becoming the only double Olympic venue in the world that could operate both water and ice events at the same time. After the Winter Olympics, it became the first Winter Olympics competition venue that was open to the public and opened the "water and ice dual drive" mode. The ice sports center was located 11 meters underground in the south square. It had a standard ice rink of 1830 square meters and a curling field with four standard curling tracks of 45 meters by 5 meters. The overall operating area was 8000 square meters. - Beijing's Huaxi LIVE Ice Center was located on the southeast side of the Cadillac Center. It was also known as "Ice Flower" and had a building area of 38900 square meters. It included two standard ice rinks in the north and south. It was officially opened to the public in June 2022. The North Ice Rink was used as a public skating and figure skating training venue, and the South Ice Rink was used as an ice skating training venue. In addition, there are real ice skating rinks and Ice Bear Ice Sports Center in the plaza.(Building D1 - 2, No. 888, Southwest Road, Shahekou District, covers an area of about 3500 square meters, and the ice surface area is about 1800 square meters. It can be used for figure skating, short track speed skating, ice skating, etc.), Champion Ice Arena (Located in the Outlets, the first professional indoor ice rink in the city, with an overall area of more than 2000 square meters and a real ice surface of more than 1000 square meters), Chen Lu International Ice Center (Shahekou District, Xi'an Road, No. 107, Central Avenue, 4th floor, tourism and cultural shopping center, with 3000 square meters of indoor real ice rink, 1456 square meters of real ice surface), blue ice skating rink (Xigang District, No. 569, 5th floor, Central District, 66 Wusi Road, the total area of the whole stadium is 1400 square meters) and other indoor ice skating rinks. Although the indoor ice skating rink was made of artificial ice, the indoor temperature was generally controlled at-5 to 10 ° C. The air humidity was low, and the wall of the ventilation pipe was prone to condensation. If it fell on the ice surface, it would form ice lumps. In order to ensure safe and long-term operation, it was necessary to use electric heat tracing to prevent condensation of the ventilation pipe. For example, two self-limiting electric heat tracing belts were attached to the inner wall of the aluminum square pipe in parallel. The electric heat tracing belt and the side wall of the aluminum square pipe were maintained at 2 - 3cm and covered with aluminum foil tape.

Is the ice-skating rink cold?
The temperature of the ice-skating rink varied. The indoor ice skating rink's room temperature was generally maintained below 15 ° C, and the ice surface temperature was adjusted to-5 - 6 ° C. In order to provide the fastest skating experience, some ice skating rinks would maintain the ice surface temperature at-7 ° C, and some ice skating rinks would have an ice surface temperature close to-273 ° C. The temperature of the outdoor ice skating rink was affected by the external environment. For example, the average temperature of the ice skating rink was below-5 ° C all year round, and there were also ice skating rinks with temperatures of 7 - 8 ° C above zero. Therefore, compared to the indoor temperature (usually around 20 ° C), the ice skating rink was relatively cold.

Is it cold on the ice skating rink?
There were different standards for the temperature of the skating rink, which would affect whether the skater felt cold or not. The indoor ice rink's room temperature was generally maintained below 15 ° C, the ice surface temperature was adjusted to-5 - 6 ° C, and some ice rinks maintained the ice surface temperature at-7 ° C (because the ice was the most slippery at-7 ° C). In such a temperature environment, the skater might not feel particularly cold when wearing a skating suit suitable for low temperatures, because the body would generate heat during the exercise. However, if the ice surface was cold and the room temperature was also low, one might feel cold if they stood still for a long time. In addition, different people had different degrees of tolerance to the cold. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
What is the ice skating rink made of?
The materials used to make the ice rink were as follows: 1. ** Fillers **: Generally a mixture of water and ice. This mixture can solidify into ice at temperatures below 0 ° C. 2. ** Ice protection material **: - [Ice Mask: A transparent plastic film that covers the surface of the ice to prevent it from being affected by sunlight, wind, and rain.] - [Ice surface fiber material: Can form a protective layer on the ice surface to prevent the ice surface from being worn and scratched.] 3. ** Ice Rink Edge Material **: - ** Steel plate **: Strong, can prevent the ice surface from being damaged by external impact. - ** plastic board **: Light weight, easy to install and disassemble, suitable for temporary ice rinks. In addition, there was also a simulated ice rink, which was made of high-molecular materials. It was designed and made with complicated craftsmanship. The various plates could fit perfectly. The ice surface had excellent sports performance, and the sliding experience was as high as 96% similar to real ice.

What happened to the ice in the skating rink?
The common ways to make ice in an indoor skating rink were as follows: 1. ** Foundation layer preparation **: First lay the cooling pipe, which is buried in the cement layer. Below the cement layer, there are isolation layers, heating cement layers, sand layers, and other foundation layers. After these foundations are laid, the ice can be made. 2. ** Freezing to form ice **: - One was to use a liquid nitrogen cooling system. First, water was poured into the pool, and then liquid nitrogen was injected into the laid pipeline to quickly cool the water to form an ice surface about 1 - 2 inches (2.5 - 5cm) thick. Then, special machines were used to clean the ice surface. In addition, nitrogen and other chemicals would be added to the water to increase the freezing point of the water so that it would not melt when it was slightly higher than the freezing point of ordinary water (0 degrees Celsius). This would not only prevent people from being too cold, but also reduce the energy consumed by the cooling system. However, the hardness of the ice would be reduced, and the temperature of the ice would be about-2 to-5 degrees. - In the ice making process that was carried out according to the Beijing Winter Olympics model and standards, the ground temperature was first lowered to below zero, and then the cement ground was covered with mist spray. Then, white base paint was sprayed, and the paint was sealed with water mist for about 20 times without interruption. The runway line and the starting and finishing lines were also drawn. Then, the water was added to thicken the surface manually. Finally, the ice maker was trimmed. The standard thickness of the surface layer was 3 mm, with an error of no more than 0.4 mm. 3. ** Ice surface follow-up treatment **: Different ice sports have different requirements for the ice surface. For example, the thickness of the ice surface in the curling arena should be 5 - 6 cm, and a layer of tiny ice particles should be sprinkled on the ice surface to change the friction of the track through brushing the ice. The humidity of the curling competition venue should be below 50%, and the temperature of the ice surface should be around-6 ° C. The temperature of the ice arena area should be 15 + 2 ° C, and the best temperature in the stadium should be lower than 24 ° C. The ice temperature of the ice curling competition venue should be maintained at-6 ° C. In addition, the water used to make ice should be pure water, which could not contain impurities, because impurities would cause gaps between the ice crystals, making the ice not strong and hard enough. The purer the water, the denser and harder the ice formed. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
The temperature of the indoor ice skating rink
Generally speaking, the indoor real ice skating rink's room temperature should be maintained below 15 ° C, and the ice surface temperature should be adjusted to minus 5 - 6 ° C. During the ice skating competition, the ice surface temperature was required to be maintained at-6 ° C, and the audience's temperature was set at 20 ° C. Some indoor ice rinks could maintain the temperature at-10 ° C throughout the year. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
