U48 Textile Color Fastness Ultraviolet Aging Test Chamber

The carbon arc aging tester generates arc illuminating by alternating current to illuminate the carbon rod. After passing through the filter, the light source has a higher irradiation energy than the sunlight, so that when the surface of the sample is irradiated by light source, the aging of the sample can be accelerated. At the same time, because the tester is equipped with a sprinkler, in addition to simulating the sun solarization, it can also simulate the rain environment, that is, the weather resistance of the sample can be well tested by the acceleration method.

Carbon Arc Aging Tester SI80 Standards:

Features:
1. In daily use, the material may be exposed to outdoor sunlight, glass windows or indoor artificial light for long time or wet by rain, causing fading, yellowing or changes in physical properties such as strength. We call the process natural aging. The tester can evaluate the anti-aging properties of materials more quickly than natural aging tests.
2. It adopts an electric light source that emits a discharge arc and emits light when the two carbon rods are in contact with each other after being energized in the air. It is the core component of carbon arc weather-resistant equipment. It consists of 4 pairs of carbon rods. The upper carbon rod is thick and the lower carbon rod is thin. The carbon rod is surrounded by the filter lens. The carbon arc lamp source passes through the filter lens to generate light of various wavelengths similar to sunlight, and radiates to the surface of the test sample. And the distance between the upper and lower carbon rods is controlled by the carbon rod up and down moving drive device, so as to ensure that the carbon arc voltage and current are stable within the standard error range.

SI80 Carbon arc aging tester,is widely used in plastics, paint coatings, inks, packaging, automotive materials, actinic materials, pigment dyes, textiles and other fields.
