The yellowing resistance tester and the xenon lamp weatherproof test box, together with the ultraviolet light weatherproof test box, are called three pieces of light aging. The products are widely used to simulate the ultraviolet radiation and heat of sunlight. The sample is exposed to ultraviolet rays in the machine. After irradiation and temperature, after a period of time, observe the degree of yellowing resistance of the sample. The gray level of the stain can be used as a reference to determine the grade of yellowing. The test time depends on the manufacturer's agreement. The machine has complete accessories, which can be used as a basic anti-yellowing test. It can also be used as an aging test machine and an oven to present a multi-purpose function. The yellowing resistance testing machine complies with international standards such as ASTM D1148.
The yellowing resistance test strip is designed and manufactured according to ASTM D1148. Its function is to simulate the ultraviolet radiation and heat of sunlight. The sample is irradiated with ultraviolet light and temperature in the machine. After a period of time, the sample is observed to be resistant to yellowing. The gray color is used as a reference to determine the grade of yellowing. The product is exposed to sunlight during transportation or during transportation. The color change caused by the environment of the container causes the product to be damaged. This machine uses a 300W UV bulb to make The experiment can be completed in a short time. This machine can be used as a basic anti-yellowing test, and can also be used as an aging test machine and an oven to present a multi-purpose function.
