After absorbing UV light, active free radicals or ion radicals are generated, thereby initiating polymerization, cross-linking and grafting reactions, and converting the material from liquid to solid within seconds. In the process of UV lamp emitting UV light, the substances in the UV lamp will generate heat in the high-energy excited state, which will affect the UV lamp's lifespan. Therefore, the UV lamp needs to be cooled.
