The ultraviolet aging test box simulates the ultraviolet radiation and condensation in natural sunlight to carry out accelerated weather resistance test on the material to obtain the result of the material weather resistance. By reproducing environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc., they are combined into one cycle, and it is automatically executed to complete the number of cycles. It is suitable for aging test of non-metallic materials against sunlight and artificial light sources. A fluorescent ultraviolet lamp is used as a light source to simulate and strengthen the ultraviolet spectrum that has the most significant impact on the degradation of polymer materials, and to appropriately control the temperature and humidity to periodically produce condensation on the sample. The damage caused by the YSL / ZN-P ultraviolet aging test box includes: discoloration, discoloration, reduction in brightness, chalking, cracking, blurring, embrittlement, strength reduction and oxidation. Reliable aging test data can make accurate correlation prediction on the weather resistance (aging resistance) of the product, and help the screening and optimization of materials and formulations.
Structural characteristics of YSL / ZN-P ultraviolet aging test box:
1. Box shell material: A3 steel plate sprayed with plastic;
2. Liner material: SUS stainless steel plate;
3. Box cover material: A3 steel plate sprayed;
4. Install a total of 8 UV-A ultraviolet lamps on both sides of the studio;
5. The heating method is inner tank water tank heating, which has a fast temperature rise and a uniform temperature distribution;
6. The box cover is bidirectional flip type, easy to open and close;
7. The water level of the inner tank is automatically replenished to prevent the heating tube from being burned;
8. The sample holder is made of stainless steel or aluminum alloy;
9. The bottom of the test box uses high-quality fixed PU movable wheels;
10. The drainage system uses vortex and U-shaped sedimentation devices to drain water;
11. The surface of the sample is parallel to the plane of the UV lamp;
12. If the door of the cabinet is opened when the lamp is on, the machine will automatically cut off the power supply of the lamp and automatically enter the balanced state to cool, so as not to hurt the human body;
13. Over-temperature protection in the box. When the temperature in the box is too high, the machine will automatically cut off the power and enter the equilibrium state for cooling.
Features of control instrument of YSL / ZN-P ultraviolet aging test box:
1. A 128 × 32-dot liquid crystal display (LCD) is used, which can display multiple screens (operation screen, operation parameter setting screen, initialization parameter setting screen, etc.);
2. Adopt universal input;
3. Realized an epoch-making large-scale 5-digit display;
4. There is a USB communication interface on the left side of the test chamber, which can be connected to a computer, and the relevant data can be read, recorded and printed on the computer
5. Has a wealth of arbitrary computing functions to achieve high-quality control.
6. Operation mode: program operation or constant operation;
7. Independent control time and alternating cycle control time of light and condensation can be set arbitrarily within a thousand hours
8. Light, condensation and spraying can be controlled independently or alternately
9. Adjustable light intensity
10. American LAB UV lamp and power supply (ensure that the UV lamp can be lit every time it is turned on)
11. The radiation amount is directly displayed on the instrument and the special ultraviolet irradiance meter for measurement
12. The radiometer adopts probe type
13. The independent control time of light and condensation and the time of alternating cycle control can be set arbitrarily within a thousand hours
14. The ultraviolet weather resistance test chamber should have a working time accumulation timer and a power-on self-test function;
15. During operation or setting, if an error occurs, a warning signal will be provided
Simulate the environment for quality and create value for users.
