Analysis of the causes of natural rubber sheet aging and protection methods
Natural rubber sheets are made of polymer materials and are widely used in laboratories, power plants, substations and other places. Although the natural rubber sheet has excellent characteristics, it also has a disadvantage, that is, the limitation of the service life, in other words, aging will occur to varying degrees. So what exactly causes them to age? What should we do to prevent it from aging? Below, I will explain to you the causes of aging and protection methods of natural rubber sheets.
During the processing, storage, and use of natural rubber boards, due to the combined effects of internal and external factors, the performance gradually decreases, and eventually the use value is lost. This phenomenon is called aging. And the phenomenon of aging of natural rubber sheet is various, such as: it will harden, become brittle or sticky when stored for a long time; it will change color, become brittle and even crack after being exposed to sunlight and rain; Cracking and even affecting insulation; fracture due to hydrolysis; damage caused by mold; etc. These are the causes of natural rubber sheet aging and the changes that occur due to aging.
The aging process is an irreversible chemical reaction, which will be accompanied by changes in appearance, structure and performance. Although we cannot prevent the aging of natural rubber sheets, we can use methods to maintain them and make them age slowly. For example: paraffin, rubber-plastic blending, plating, coating, etc. can be added to rubber, or chemical antioxidants can be added.
The above is the introduction of the causes and protection methods of natural rubber sheet aging. I hope to help everyone better understand the causes of natural rubber sheet aging and learn to use methods to slow the natural rubber sheet aging phenomenon.
