Usually does not seem to be a very good understanding of some of the gas, in fact, he played a big role in life, although in life we are not scientists, nor researchers, are positive contact with these gases, but he developed things are applied to all aspects of our lives, can play an indirect contact process.
1. The formation of xenon
Xenon is a rare gas, one of the elements in the 18th group of the periodic table, colourless, odourless, tasteless, chemically inactive, exists in the air, every 100 ml of air contains xenon 0.0087 ml. Also exists in the hot springs of gas, from the liquid air with krypton was separated to get xenon in July 1898, by Ramage and Travis at University College London found that before that in the air After extracting neon, argon and krypton from the air and wondering if it contained other gases, industrialists gave them a new liquid air machine with which they extracted more rare gases krypton, and after many distillations they finally isolated a heavier gas that emitted a beautiful blue light in a vacuum tube. They realised that, because of its chemical inertness, it was another member of the inert group of gaseous elements and chose the name xenon.
2. The advantages of xenon in life
Hernia is widely used in electronics, light power industry, also used in gas lasers and plasma flow, with xenon gas-filled bulbs and the same power argon bulbs, compared with a high luminous flux, small size, long life, power-saving advantages, such as hernia lamps have a very high luminous intensity, a 60,000-watt monolamp brightness, equivalent to nine hundred one hundred watts of ordinary light bulbs, due to the xenon has a virtually continuous spectrum, So it can be used in the high-voltage arc discharge under the action of producing similar daylight and bright white light, this long arc xenon lamp, commonly known as the artificial small sun, due to the ability to penetrate the fog is particularly strong, can be used as a fog navigation lights, Xenon flash lamps with good colours, used to shoot colour films, line lamps can release ultraviolet light, in the medical treatment is also applied, xenon isotopes are used to measure cerebral blood flow and study lung function, calculate the amount of insulin secretion, and so on. Concave surface after the concentration of light, can generate 2500 degrees high temperature, can be used for welding or cutting refractory metals such as titanium and molybdenum, but also a deep anaesthetic without side effects, it can be dissolved in the cell fat to cause cell expansion and anaesthesia, Thus, the role of nerve endings to temporarily stop, but also absorb X-rays, initially also used as a shielding of X-rays, in addition to xenon in the nuclear reactor and high-energy physics are also has a wide range of applications.
3. Xenon gas precautions
Xenon is a colourless, odourless, non-toxic, non-flammable, high-pressure gas stored in cylinders. As its content increases, resulting in an oxygen content of **19.5%, it can cause asphyxiation. Xenon gas is a high-pressure filled gas, the use of pressure should be reduced to lower the pressure before use, packaged cylinders have a life expectancy, where the expiry of the cylinder must be sent to the relevant departments for safety inspection before continuing to use. Each bottle of gas in the use of tail gas, should be kept in the bottle residual pressure in 00.5MPA, smaller does not ** 0.25MPA residual pressure, the bottle valve should be closed to ensure that the quality of gas safety and use. Bottled xenon gas in the transport storage and use, should be classified and stacked, it is strictly prohibited combustible gases and combustion gases stacked together can not be close to open flames and heat sources, it should be done away from the near fire, do not stain the oil and wax, no exposure to the sun, no heavy throw, no impact, it is strictly prohibited to arc and arc on the body of the gas cylinders, and prohibit the barbaric loading and unloading.
