Sunlight simulation chamber for vehicle parts in customer testing lab:
Taking something about material aging:
The aging of plastics is mainly due to the weakness of the structure or components, such as unsaturated double bonds, branched chains, carbonyl groups, hydroxyl groups at the end, and so on.
External or environmental factors are mainly sunlight, oxygen, ozone, heat, water, mechanical stress, high energy radiation, electricity, industrial gases (such as carbon dioxide, hydrogen sulfide, etc.), sea water, salt fog, mold, bacteria, insects, etc.
The usual aging tests mainly include light aging, humid heat aging, hot air aging, high and low temperature test, salt spray corrosion, ozone aging, thermal oxygen aging test, buried soil corrosion test, liquid medium aging test, User specific condition aging test, etc. Illumination aging is also divided into many kinds, there are indoor aging and outdoor aging. The indoor aging has xenon lamp aging, fluorescence ultraviolet aging, carbon arc aging and so on.
Outdoor aging means exposure to test sites, including Florida and Arizona abroad, and Hainan,
Dunhuang, Mohe, Lhasa and so on in China. These test sites are basically distinguished by dry heat and humid heat.
These method are commonly used in laboratory tests to accelerate the aging time of samples.But one common problem with these aging tests is that they can only simulate one of the full spectrum light waves, such as 300-400nm.It has to be mentioned here that metal halogen lamp aging, that is, full spectrum sunlight simulation aging test.This is the closest aging method to sun light, with a radiation band range of 280-3000nmm.
It can usually be used to make materials, parts or the aging of the full car testing.
