Application：
Bench-top UV Light Accelerated Aging Test Chamber is suitable for accelerated aging test through ultraviolet light, temperature and water exposure, used to predict the relative durability of non-metallic materials such as coating film, plastic, rubber, etc., especially suitable for observing the physics of particularly durable materials The degree of performance damage, such as reduced gloss, haze, reduced strength, chalking, cracking, blistering, embrittlement, and color fading.
Paint Industry: For testing various coatings, including:
Hull paint
Marine waterline paint
Deck paint
Solvent-based polyurethane wood paint for interior decoration
Water-based wood paint for interior decoration
UV-curing wood paint
Pre-coated coil coatings for home appliances
Indoor water-based wood coatings
Coil coatings
Architectural water-based fluorine coatings
Other Industries:
Automotive Industry: For evaluating paint and coatings.
Plastic Products: To assess UV degradation and durability.
Wood Products: Testing finishes and coatings for weather resistance.
Glue: To determine the effects of UV exposure on adhesive performance.
Like all artificial weather accelerated aging test equipment, the test results obtained by the desktop UV fluorescent ultraviolet aging test chamber cannot replace natural exposure to determine the actual durability of the material, but this instrument can provide a reliable relative test result, which is very useful for quick evaluation. Anti-aging properties of materials, screening or improving new and old formulas, and monitoring product quality are more practical.
Main Performance：
The Bench-top UV Light Accelerated Aging Test Chamber uses three 20W fluorescent ultraviolet lamps with a wavelength of 313nm as the experimental light source. During the test, basic parameters such as total light time, temperature in the box, and spray time can be set to simulate the nature of the outside world. The damage caused by the environment is used to evaluate the weather resistance of the model.
The all-stainless steel sandwich liner design will never rust and leak water, while effectively preventing water vapor in the working room from penetrating into the electrical part and damaging the electronic components.
Built-in water level switch, the machine will alarm and stop automatically when the water level is low.
Use the ultraviolet lamp tube produced by a professional company, the irradiation energy is high: the new lamp tube can reach 0.9W/m2.
The touch screen man-machine interface directly sets various parameters required for the test, and it is convenient to check the parameter running status during the test at any time.
