ZN-P Tower UV Aging Test Chamber

The tower type ultraviolet aging test chamber can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climate. By reproducing these conditions, they can be merged into a cycle and automatically executed to complete the cycle.

The ultraviolet aging test chamber (also known as the ultraviolet accelerated aging test machine) is mainly used to simulate environments such as ultraviolet radiation, high temperature, high humidity, condensation, and rainwater in sunlight, to accelerate the aging process of materials in the laboratory and quickly evaluate their weather resistance and service life.

Core testing function

　　simulated environmentSimulate the destructive ultraviolet band in sunlight through fluorescent ultraviolet lamps (UVA/UVB), combined with condensation (simulating dew) and spraying (simulating rainwater) functions, to reproduce the complex outdoor climate.

　　accelerated agingBy utilizing high-intensity and controllable ultraviolet radiation, combined with high-temperature and high humidity cycles, the outdoor aging process of months or even years can be compressed into a few days or weeks.

　　Evaluate performanceObserve and quantify the performance changes of materials before and after aging, such as:

Appearance: Fading, discoloration, loss of luster, powdering, cracking, foaming, brittleness, blurriness, oxidation, etc.

Performance: tensile strength, impact strength, adhesion, glossiness, etc.

Main application areas

　　Coatings and inksEvaluate the weather resistance of building exterior paint, automotive original paint, industrial anti-corrosion coatings, wood paint, and various inks for formula optimization and warranty life prediction.

　　Plastic and rubberTest the aging behavior of plastic products (such as household appliance shells, car bumpers), rubber parts (such as sealing rings, tires), and cable sheaths under light and humid heat, and guide material selection and formula improvement.

　　automotive industryConduct tests on car paint, interior and exterior decorations (plastic, leather), lamp covers, sealing strips, etc. to ensure their appearance and performance stability under long-term sunlight and humid environments.

　　Architecture and Building MaterialsVerify the weather resistance of exterior wall coatings, plastic door and window profiles, waterproofing membranes, roof materials, and sealants to provide data support for engineering design.

　　Electronics and ElectricalEvaluate the reliability of polymer materials such as phone/drone casings, wire and cable sheaths, connectors, etc. in light and humid environments to prevent cracking, discoloration, or strength degradation caused by aging.

　　Textile and Printing and DyeingTest the light fastness and strength retention of outdoor textiles, sunshades, advertising fabrics, clothing fabrics, etc., to ensure the durability of the products in outdoor use.

　　packaging materialsAssess the UV aging resistance of materials such as beverage bottles, food packaging films, and cosmetic packaging to prevent discoloration, brittleness, or mechanical performance degradation due to light exposure during the shelf life.

　　New energy (photovoltaic)Specially test the UV stability of photovoltaic module packaging materials (such as EVA, POE) and backplates, evaluate their risks of yellowing, cracking, delamination, etc. under long-term light exposure, and provide data basis for the 25 year warranty of the modules.

　　Research and Quality InspectionUsed for the research of material weather resistance evaluation methods and as a standard testing equipment for third-party laboratories or enterprise quality inspection departments to perform various weather resistance tests.
