What is chlorofluorocarbon?

chlorofluorocarbon (CFC) is a gas compound of several basic elements, including fluorine, chlorine, carbon and hydrogen. Chlorofluorocarbons developed in the 1930s, due to their relative stability and safety became very popular in cooling and aerosol technologies. Scientific discoveries from the end of the 20th century revealed that CFC play an important role in the exhaustion of the ozone layer; Since this discovery of the International Environmental Treaty, the use of CFC has significantly reduced the use of CFC.

The creation of chlorofluorocarbon compounds dates back to the 19th century, but commercial production of compounds was not improved until the 1930s. In search of a safe, non -toxic alternative to poisonous and explosive materials used in cooling and cooling, such as ammonia, sulfur dioxide and even propane, Thomas Midgely, American inventor, began experimenting with the addition of fluorine to hydrocarbons. The result of his test was the Comlibra that provided the properties of the coolant without high rIzika flammability; Midgely was considered a genius and the cooling landscape quickly and indelibly changed.

In addition to their use as cooling substances, chlorofluorocarbon compounds soon became popular in other consumer products. It has been found that new variations of chlorofluorocarbon work very well as propellers, which make them ideal for sprays and liquid suspension. Shaving cream, asthma inhalers, hair spray and all kinds of spray or foam products commonly used CFC to create an even and non -toxic dispensing system.

As scientists soon found out, the amazing properties of chlorofluorocarbons had hidden danger, mainly because of chlorine in their make -up. As CFC rises by the atmosphere, they are covered with ultraviolet rays that cause chemical disintegration and release chlorine. Chlorine that is naturally unusual in the atmosphere is able to consume and destroyOzone molecules. With the huge commercial popularity of chlorofluorocarbon during the 20th century, people suddenly began to release a huge amount of CFC into the air, leading to a gradual but severe exhaustion of the protective ozone layer of the atmosphere.

In 1985, many scientists confirmed a rapidly growing hole in the ozone layer and held a compound of chlorofluorocarbon during its existence. In an effort to reduce damage and give ozone a chance to repair, many countries began to sign protocols that banned or seriously reduced the use of compounds in almost all products. Although the use of CFC has decreased significantly since the end of the 20th century, CFC compounds can only remain in the atmosphere for a century, which means that the full range of damage and recovery capacity remains unknown.
