The properties of electroplated parts or the base material of electroplated parts will change with time in a certain environment. This is the aging process. The main factors that have been determined to affect the environmental aging of materials or product coatings are the following:
① Solar radiation is mainly ultraviolet rays, which is the biggest cause of aging of most materials:
②Hot ambient temperature:
③Damp dew, rain, moisture:
④Pollutants suspended particles, acid rain, ozone, etc.
Because these factors vary greatly on the earth's surface, the environmental aging of materials or products does not follow a certain fixed scientific theory, and their performance will also change with changes in climatic conditions and chemical properties of materials. In fact, the environmental test is done using static and accelerated methods, because the climatic factors that affect the environmental adaptability of materials or products are very changeable, usually several different test methods are used to test the comprehensive chemical properties of materials or products. characteristic.
