Applications of water and gas hose in agriculture and construction
During the use of rubber hoses, the properties of rubber will change due to the combined influence of various factors, causing the performance of rubber and its products to gradually decrease over time until they are damaged and lose their use value. This process is called rubber aging. Rubber hose aging will cause economic losses, and to reduce these losses, slowing down aging to extend the life of the hose is one of the methods. To slow down aging, we must first understand the factors that cause hose aging.
Oxidation reaction is one of the important reasons for rubber hose aging. Oxygen will react with certain substances in the rubber hose, causing changes in rubber properties.
Increasing the temperature will accelerate the aging of rubber. On the other hand, when the temperature reaches the corresponding level, the rubber itself will undergo thermal cracking and other reactions, thereby affecting the performance of the rubber.
The role of ultraviolet rays
Light also has energy, and the shorter the light wave, the greater the energy. Among them, ultraviolet rays are a type of light with higher energy, which can damage rubber. Rubber generates free radicals due to the absorption of light energy, which triggers and accelerates the oxidation chain reaction. On the other hand, light also plays a heating role.
When exposed to humid air or soaked in water, water-soluble substances in rubber will be extracted and dissolved by water. Especially when immersed in water and exposed to the atmosphere, the destruction of rubber will be accelerated.
