Currently, the method of understanding the aging resistance of waterproof boards is by various means.Waterproof SheetAging tests were conducted to evaluate the material's resistance to aging, including standard tests such as heat resistance, climate resistance, humidity-heat tests, salt spray tests, and cold resistance. The data obtained from these tests can accurately and objectively assess the aging properties of the waterproof board as well as its resistance to acids, alkalis, and salts.

One of the commonly used thermal resistance tests - the hot air aging chamber
Heat is one of the primary factors that promote aging reactions in waterproofing board materials and high polymers. It can cause the molecular breakage of high polymers, leading to the formation of free radicals, which then trigger a chain reaction, resulting in polymer degradation and cross-linking, and ultimately, a deterioration of properties. The red idea aging test is a commonly used method for heat resistance testing. It involves placing the sample inside a selected condition thermal oven, periodically checking and testing for changes in the appearance and properties of the sample to evaluate its heat resistance. This method is frequently applied to plastics and rubbers, and it is also used for heat resistance tests of information recording materials.
