Rubber samples (natural and manmade) are aged at accelerated rates, by exposing them to elevated ozone levels, temperature, and humidity.
Natural rubber is easily attacked by many oils, and solvents. In the open, ozone also attacks the intermolecular bonds.
The natural dynamic equilibrium of stratospheric ozone involves the continuous creation and destruction of ozone molecules. Ozone is formed when oxygen molecules are broken apart by solar radiation, and it is destroyed by various chemical reactions involving other compounds in the atmosphere. This balance helps maintain a relatively stable ozone concentration in the stratosphere.
Rubber can be ruined through exposure to extreme temperatures, both high and low, which can cause it to become brittle or lose elasticity. Additionally, prolonged exposure to UV light, ozone, or certain chemicals, such as oils and solvents, can lead to degradation and cracking. Physical damage, such as cuts or abrasions, can also compromise its integrity. Regular maintenance and proper storage are essential to prolonging rubber's lifespan.
The ozone is a natural cycle. It is because various factors that cause ozone depletion also replenish it.
Exposure to ozone can worsen asthma symptoms by causing inflammation and irritation in the airways, leading to difficulty breathing and increased asthma attacks.
Natural methods of ozone depletion are many. Lightening and thunder are some of them.
Ozone can spread. Ozone replenishment is a natural process.
The two main types of ozone depletion are natural ozone depletion and human-induced ozone depletion. Natural ozone depletion is caused by processes such as volcanic eruptions, while human-induced ozone depletion is primarily the result of the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere.
Ozone present in the troposphere is also called as bad ozone. It is also a green house gas. It is the major constituent of the urban smog.
There exists a natural equilibrium. It maintains the creation and depletion of ozone.
Certain types of bacteria and fungi are known to degrade rubber over time. For example, specific microbial species, such as those from the genus Nocardia, can consume rubber as a carbon source. Additionally, exposure to ozone and UV light can lead to the degradation of rubber materials, causing them to break down slowly. Environmental factors like heat and moisture can also accelerate this process.
The depletion of ozone is both natural and man made. The natural is by UV rays and man made by CFC's.
