INQUIRY

Anti yellowing aging test chamber is suitable for simulating the ultraviolet radiation and heat of sunlight. The sample is exposed to ultraviolet radiation and temperature in the machine. After a period of time, observe the yellowing resistance of the sample. The stained gray can be used as a reference. Determine the level of yellowing.

Applications:

The machine can do two tests: anti-yellowing and aging.

1.Anti-yellowing: to stimulate the environment condition, driven by the sun ultraviolet radiation. It's generally thought that the appearance change at 50'C for 9 hours, in theory as exposed to atmosphere for 6 months.

2.Aging: it can promote the increase of sulfur rubber deterioration so as to calculate the change rate of tensile and elongation before and after heat. Its generally thought that test for one day at 70C, in theory as exposed to the atmosphere for 6 months.

Test Standard:
GB/T2951.21-2008 GB/T7762-2003 GB/T2951.5 -1997

Cabinet structure:
1. Inner box material: SUS304# stainless steel plate (thickness 1.2mm)
2. Outer box material: SUS304# stainless steel plate (thickness 1.2mm)
3. Door handle: non-reaction, explosion-proof door handle is adopted, which is easy to operate, safe and reliable.
4. Moving and positioning device: The bottom of the machine is equipped with high-quality fixed PU movable wheels, which can easily move the machine to the designated position, and then fix the casters.
5. Observation window: Double-layer vacuum strengthened glass is used to observe the test process clearly.
6. Sample rack: SUS304# stainless steel punched and bent into a net shape, easy to use, and the spacing between the material racks can be adjusted.
