The anti-yellowing aging test chamber is suitable for simulating ultraviolet radiation and heat of sunlight. The equipment meets two kinds of test conditions: aging and yellowing resistance. Aging refers to promoting the deterioration of vulcanized rubber to calculate the rate of change of tension and elongation before and after heating. It is generally believed that testing at 70 °C for one day is theoretically equivalent to exposure to the atmosphere for six months. Yellowing resistance refers to the experiment of simulating various light effects according to the principle of light yellow and white materials or products easily yellowing in the simulated atmospheric environment. The appearance change is generally considered to be tested at 50 ° C for 9 hours, theoretically equivalent to exposure. 6 months in the atmosphere. The test piece slewing device ensures that the test piece is heated and irradiated evenly and comprehen-sively, and the test accuracy is improved.
