Some of the ice in the ice-skating rink was real ice. For example, Jingdezhen's newly opened ice skating rink, the ice skating rink at the Wanda Plaza, and the ice skating rink at the Arctic Ice Pavilion were all real ice skating rinks.

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.

The English words for " skating rink " were " skating rink " or " ice rink." While watching the Olympics, you can also read the wonderful novels related to the Olympics!

Different events had different requirements for the ice surface. In terms of thickness, the ice thickness of short track speed skating was required to be 3 cm to 5 cm, speed skating was required to be 2.5 cm to 3 cm, and figure skating was required to be 6 cm to 7 cm. In terms of temperature, the ice temperature of short track speed skating was-7 ° C to-6 ° C, speed skating was-9 ° C to-5 ° C, and figure skating was-4 ° C to-3 ° C. In addition to these, other ice projects not only had strict requirements on thickness and temperature, but also required the ice surface to be extremely flat, with an error of no more than 0.5 millimeters. For special events such as curling, which had extremely high requirements on the ice surface, each square meter of ice surface had to be able to withstand a weight of 150 kilograms, and the degree of distortion of the ice surface did not exceed 1 mm.

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.

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!

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.

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.

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.
