Equipment Overview
It is used for simulating sunlight, rain, and dew environment, to
inspect the damages to samples (including but not limited as
coating, ink, paint, resin, plastic, rubber, printing and
packaging, aluminum profiles, adhesives, automobile and motorcycle
components, cosmetics, metal, electronics, electroplating,
medicine, etc.) caused by sunlight, rain, and dew.
Test principle: Fluorescent UV lamps can reproduce the influence of
sunlight, condensation and water sprinkler systems reproduce the
effects of dew and rain, the material is tested in a cyclical
program of alternating light and moisture at a certain temperature.
UV can reproduce the hazards of outdoor months to years in a matter
of days or weeks. Types of hazards include: color fading,
discoloration, loss of light, chalking, cracking, turbidity, air
bubbles, embrittlement, strength decay, and oxidation.
