First of all, the durability of home appliance plastic parts mainly depends on the material selection. High-quality plastic materials, such as polypropylene (PP) and polycarbonate (PC), have good physical properties and chemical stability, and can effectively resist the erosion of the external environment, thereby extending the service life of home appliances.
Secondly, aging is an inevitable problem of home appliance plastic parts during use. Plastic aging is mainly manifested in discoloration, loss of gloss, cracking, and powdering, which is due to chemical changes in the molecular structure of plastics under the influence of external factors such as light, heat, and oxygen.
In order to improve the durability of home appliance plastic parts and delay the aging process, a variety of measures can be taken. For example, anti-aging agents such as antioxidants and ultraviolet absorbers are added to plastics. These additives can effectively capture free radicals and absorb ultraviolet energy, thereby inhibiting the aging reaction of plastics.
In addition, the optimization of the injection molding process also has an important influence on the durability of home appliance plastic parts. By precisely controlling parameters such as injection molding temperature, injection pressure, holding time, and cooling process, the uniformity and density of plastic parts can be ensured, thereby improving their anti-aging ability.
During the product design phase, it is also necessary to consider how to improve the durability of home appliance plastic parts. For example, avoid sharp corners and sudden changes in wall thickness to reduce stress concentration; for parts used outdoors, appropriately increase the wall thickness or strengthen the structural strength to improve its ability to resist ultraviolet rays and temperature changes.
At the same time, home appliance plastic parts also need to be maintained and cared for during use. Avoid prolonged exposure to sunlight or high temperature environments, and regularly clean and check the surface of the parts for signs of damage or aging.
Finally, for home appliance plastic parts that have aged, they need to be replaced in a timely manner to avoid safety hazards. At the same time, home appliance manufacturers should also continuously improve materials and processes to improve the overall durability and safety of their products.
