What is the storage method of plastic barrels?

- Oct 23, 2020-

The chemical reaction of plastic barrels exposed to the sun is caused by multiple factors. First of all, ultraviolet light, the dominant factor in photochemical reactions, can directly cause molecular chain breaks. Among all the light, the shorter the wavelength and the greater the energy, the more it can accelerate the aging of the plastic barrel, because rubber and plastic materials will produce free radicals when absorbing light energy, which will initiate and accelerate some unfavorable chain reactions. . In addition, when the plastic barrel is exposed to light, there will usually be a temperature change, which can be regarded as heating, and the increase in temperature will accelerate the diffusion of oxygen, thereby increasing its oxidation rate, and triggering thermal glue and cracking, and it will Oxygen or even ozone contact, excessive glue connection or molecular chain rupture can accelerate aging, and there are other factors such as water, high-energy radiation, and the medium in which it is located. Therefore, when using plastic buckets daily, try not to expose them to the sun.https://www.fhpails.com/
