HZ‑2008A tower‑type UV accelerated aging testing chamber is accelerated weathering test equipment developed for medical polymer materials. It uses UV fluorescent lamps to simulate solar ultraviolet radiation, together with condensation and water‑spray system to reproduce dew and rain environment. It reproduces long‑term light‑aging effect of medical products within short‑time cycle. Suitable for medical catheters, silicone components, medical plastic housings, sterile packaging and polymer implant accessories. It evaluates aging failure including yellowing, discoloration, chalking, cracking, embrittlement and strength loss. It provides reliable test data for medical material selection, formula optimization, product shelf‑life verification and medical‑device registration. Widely applied in medical‑device R&D labs, incoming‑material inspection and third‑party testing institutes.
The chamber shell is numerically processed by 1.2mm thickness 304 stainless‑steel plate. Single‑cycle air duct with imported axial‑flow fan ensures uniform temperature & humidity inside cabin. Optional UVA‑340 / UVB‑313 UV lamps: 8 main lamps plus 4 spare lamps, lamp service life up to 1600h. Dual humidity simulation modes: condensation humidification and 12‑nozzle water‑spray system for dew condensation and rain thermal‑shock simulation. Touch‑screen programmable controller supports multi‑segment cycle of UV irradiation, condensation and water‑spray. Irradiance adjustable from 0.1‑1.0 W/m², black‑panel temperature controllable RT+10 ~ 80 ℃. Auto water‑filling tank with dry‑burn‑out protection. Stainless‑steel / aluminum‑alloy sample rack holds up to 50 pcs specimens (75×150 mm). Equipped with PU moving casters and U‑shaped drainage system. Designed for accelerated UV‑humidity aging test of medical polymer materials, compliant with ASTM G153, ISO4892‑2, GB/T14522 standards.
