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. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

What are the types of painkillers?

The types of painkillers used for radiation therapy were as follows: 1. For mild pain, non-steroid anti-inflammatory drugs, such as Aspirin, paraments, and ibuprofen, can be used. However, when taking them, you should follow the doctor's advice to avoid excessive use, because they may damage the stomach wall, causing indigestion, stomach bleeding, and other problems. 2. For moderate pain, you can choose weak-acting opioids (such as codeine, dextropropyramine, tramadol) or low-dose strong opioids, and can be combined with non-steroid anti-inflammatory drugs and auxiliary analgesics (sedatives, anticonvulsants, antidepressors, etc.). These drugs require a doctor's prescription and have side effects such as drowsiness, constipation, and dry mouth. 3. For severe pain, strong opioids were preferred (such as morphines, tributyl, docodone, bupranorphine, methadone, etc.), and non-steroid anti-inflammatory drugs and auxiliary analgesics (sedatives, hypnotics, anticonvulsants, antidepressors, etc.) could be used in combination. Morphosis could be administered by mouth or vein. The treatment dose usually did not cause addiction, but sudden withdrawal would cause adverse reactions. These drugs had side effects such as drowsiness, constipation, nausea, and dry mouth. 4. If it was pain caused by brain edema after radiation therapy, he could use hormone drugs such as dexamethyst or mannitol to reduce swelling and blood pressure. 5. When the radiation caused damage to the skin and caused pain, it was necessary to disinfect it well, and then use skin protectants and antibiotics such as trolamine cream, clindamylin ester gel, and mupirocin cream. 6. When abdominal pain is caused by damage to the digestive tract, it needs to be treated with protective drugs for the digestive tract (such as colloid pectin-based Bi, aluminum trioxide-based tablets). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
