Yellowing resistance aging test chamber can provide the simulative heat of the sun and ultraviolet radiation environment of space. It is used for observing the anti-yellowing degree of the sample after a period of time effected by the ultraviolet ray and the temperature. Grey stain can be used for reference standard, to judge it is yellowing degree. Products will change their color when radiated by the sun or influenced by the environment of the container. Use the UV lamp 300W, so that the experiment can be finished in a short time. The machine can also be used as an aging tester or an oven, presenting a multi-function machine.
can do two kinds of testing: aging and anti-yellowing
1. Aging: the machine can promote the increase of sulfur rubber deterioration, to calculate the change rate of tensile and elongation before and after heat. It is generally thought that test for one day at 70 degree, in theory as exposed to the atmosphere for 6 months.
2. Anti-yellowing: the machine stimulate the atmosphere environment, driven by the sun ultraviolet radiation. It is generally thought that the appearance change at 50 degree for 9 hours, in theory as exposed to atmosphere for 6 months.
