What material is the Olympic torch made of?

2008 Olympic Torch'auspicious clouds'It is made of thin, high-quality aluminum alloy material and hollow plastic parts, which is very lightweight. The lower half is sprayed with high-touch plastic paint, which is comfortable to the touch and not easy to slip off. The flare uses propane as fuel, which is a very inexpensive and commonly used fuel.

Its main components are carbon and hydrogen, and after combustion, there is only carbon dioxide and water, and there are no other substances, which will not cause pollution to the environment.

It is designed with thin, high-quality aluminum alloy materials and hollow plastic parts.

The fuel is propane with a purity of more than 99%. Historically, Olympic torches have used more mixed fuels. Propane fuel is used in order to meet the ambient temperature requirements within the flare relay route.

Secondly, color is also a consideration, the flame is orange after propane combustion, which has good visibility.

The fuel for the Olympic torch has changed with the times.

The 1936 Olympics were fueled by magnesium.

In 1960, it began to use natural resin fuel.

In 1976, it was converted to olive oil as fuel.

In recent Olympic Games, propane and other gas mixtures have been used as fuel.

The torches of the Beijing and London 2008 Olympic Games used propane.

The steps for making the Olympic torch are as follows:Material preparation: corrugated paper, red paper, old newspapers, silver tin foil, scissors, auspicious clouds and Olympic torch patterns, etc.

Operation steps: 1. First of all, roll it into a barrel with corrugated paper or cardboard, form a cone, a little wider at the top, a little narrower at the bottom, and stuff old newspapers inside for support.

2. Use red colored paper or adhesive paper to paste on the outside of the paper tube made in the previous step.

3. Draw or print the pattern of auspicious clouds and cut it out.

4. Draw the words "Beijing 2008" and cut it out.

5. Carefully paste the auspicious clouds and Olympic torch patterns on the paper tube.

6. Done. <>

This is because the Olympic torch is fueled by gases such as propane, which burn stably in extreme weather. Propane gas has the characteristics of large combustion heat, low boiling point and low temperature, bright flame without fear of strong light, liquefaction difficulty and strong pressure, etc., so as to adapt to various bad weather. The pressure stabilizing device and heat recovery device further ensure the stable combustion of the fuel.

The pressure stabilizing device can stabilize the pressure required for gas combustion and maintain the intensity of the gas flame in different weather. The return device maintains the temperature of the fuel chamber and thus the fuel combustion pressure.

The Olympic flame symbolizes peace, light, unity and friendship, and is also a tribute to Prometheus, the god of fire who stole the flame for mankind, and has a history of more than 2,700 years. According to legend, Mount Olympia in ancient Greece was the habitat of the gods, and the local people worshiped the gods every four years in order to pray for good weather and abundant crops.

The "Torch Relay" event was held at the Games and began with the 11th Olympic Games held in Berlin, Germany. At that time, German long-distance runners went to Olympia, Greece, to light the torch, and one by one carried the torch to the Berlin sports grounds. In 1959, at the first National Games, China held the "torch relay" activity for the first time.

The 1936 Olympic Games used magnesium as fuel, in 1960 began to use natural resin fuel, in 1976 it became olive oil as fuel, in recent Olympic Games have used propane and other mixed gases as fuel, and the 2008 Beijing Olympic Games and London Olympic Games torches used propane fuel. After the combustion of propane, it mainly produces water vapor and carbon dioxide, which is in line with the environmental protection concept of the Green Olympics. More importantly, propane can adapt to a wide range of temperatures, and can still produce more than 1 saturated vapor pressure at minus 40, which is higher than the outside atmospheric pressure.

Flare combustion mainly uses propane, this fuel is inexpensive, the main components are carbon and hydrogen in the shelter, only carbon dioxide and water after combustion, which will not cause pollution to the environment.

After the combustion of propane, it mainly produces water vapor and carbon dioxide, which will not cause pollution to the environment. More importantly, propane can adapt to a relatively wide temperature range, and can still produce more than 1 saturated vapor pressure at minus 40 degrees Celsius, which is higher than the outside atmospheric pressure, forming combustion. In addition, the flame of propane burned was bright yellow, and when the torchbearer ran, the dynamically fluttering flame was more eye-catching in different back orange scenes.

The Olympic torch uses trembling propane as fuel, and the fuel used is propane, which is the most inexpensive common fuel.

The Olympic torch uses propane, the main components of which are carbon and hydrogen, and only carbon dioxide and water are present after combustion, and there are no other substances, which will not cause pollution to the environment.

The fuel for the Olympic torch uses a mixture of propane and butane. The fuel uses a mixture of propane and butane, which is easy to fully burn and has less waste. It burns even in water.
