UV-master
In response to the climate resistance testing requirements for outdoor textiles, this equipment can simulate outdoor climate conditions and accelerate testing. Textiles may undergo yellowing, decline, and structural changes under the stimulation of outdoor ultraviolet radiation.
UV testing is conducted by exposing materials to high temperature control conditions and alternating cycles of ultraviolet light exposure and humidity UV uses fluorescent ultraviolet lamps to simulate sunlight, and simulates dew and rainwater through condensation or water spraying. The aging types of textiles include discoloration, loss of luster, powdering, cracking, foaming, brittleness,decline, oxidation, etc
Standards:
ASTM G151 ASTM D4329 D4329 ASTM-D4587.ASTM-G154
Technical parameters:
1. Blackboard temperature setting range:BPT 40-110 ℃; BST 40-120 ℃, but the actual temperature limit of the temperature protection device inside the machine is93 ℃± 10%.
Blackboard temperature control accuracy:± 2 ℃.Blackboard temperature sensors are consumables that require frequent wiping. The surface paint may peel off after a certain period of time, affecting the control accuracy. Therefore, if there is a significant change in color, it needs to be replaced. The specific time depends on the usage situation, usually around two years.
2. Sample size: 48 standard samples of75 * 150mmcan be placed;
3. Sample thickness: The sample thickness shall not exceed 10mm
4. UV wavelength:UVA-340
5. Simulated condensation: The condensation system time can be adjusted
6. Test time: adjustable from0 to 9999
7. Irradiance: adjustable from0 to 1.6w/m2
8. Test time: It can continuously accumulate test time without resetting due to power outages or other factors
9. Irradiance calibration: The irradiance can be calibrated at any point within the set range without changing the program being executed
10. Calibration process: The calibration process achieves automatic input correction to avoid errors caused by manual input
11. UV state, no water, operable
12. Sample space: Large sample space, can be equipped with 3D sample racks
13. Experimental status data can be transmitted through Ethernet cables
14. Lamp lifespan: UV lamp lifespan can reach over 5000 hours
15. Compliant with standards:ASTM G151 ASTM D4329 D4329 ASTM-D4587.ASTM-G154
