Aging/performance decay of polystyrene products
Sorun Belirtisi
Product performance gradually declines during long-term use or in outdoor environments, with discoloration, embrittlement and other phenomena appearing.
Neden Analizi
(1) Ultraviolet irradiation causes photo-aging of the material and molecular chain breakage
(2) Thermal-oxidative aging; the material oxidatively degrades in high-temperature environments
(3) Contact with chemical media causes chemical aging
(4) Long-term stress on the product produces fatigue aging
(5) The material itself has insufficient weather resistance
Çözüm
(1) Add antioxidants and ultraviolet absorbers
(2) Coat the product surface with a protective coating
(3) Avoid long-term exposure to ultraviolet and high-temperature environments
(4) Select material grades with good weather resistance
(5) Regularly check product condition
Temel Çıkarım
Product aging is caused by environmental factors; adding stabilizers and surface protection is key.
