Carbon dioxide is a natural, colorless gas with a sour smell. This gas, when dissolved in water, turns into carbonic acid. It is this substance that acidifies the liquid.
Carbon dioxide is not an explosive gas. In industry, it is placed in cylinders, which have found wide application in various spheres of human activity, mechanical engineering, construction and the food industry. Thanks to carbon dioxide, it is possible to store food for a long time. Carbon dioxide has the ability to completely evaporate and has a high level of refrigeration capacity. Also, this gas is actively used in the production of carbonated drinks.
Carbon dioxide is often required for the production of fire extinguishers, which are used to extinguish fires and as a shielding gas during welding. Carbon dioxide cylinders are sold wholesale and retail. All gas cylinders are filled with carbon dioxide, which is in a liquid state in accordance with GOST. Carbon dioxide cylinders come in different sizes, volumes and weights. The weight of the cylinder is indicated without taking into account the weight of the caps, rings, valves and shoes. Storage and transportation of carbon dioxide is carried out in steel cylinders in accordance with safety standards. If you handle carbon dioxide carelessly, frostbite may occur.
Carbon dioxide cylinders are always black and are marked with a yellow inscription "Carbon dioxide". They contain gaseous and liquid carbon dioxide under high pressure.
In addition to carbon dioxide, technical gases such as argon, oxygen, propane, acetylene, hydrogen, which are also offered in cylinders, are widely used. With the regular use of technical gases, the gas cylinder can be refilled repeatedly as the gas is consumed, as it is cheaper than buying a new cylinder.
