Does SO2 cause corrosion? The answer is yes. Sulfur dioxide (SO2) is a common and relatively simple sulfur oxide and one of the major air pollutants. It has strong corrosivity and reacts with homogeneous materials to form salt substances to corrode the surface of the material and disintegrate the material into particles, eventually causing the material to age, fail and damage, and also affecting t...
The UV aging test chamber uses a fluorescent UV lamp as the light source to conduct accelerated weathering tests on the material by simulating ultraviolet radiation and condensation in natural sunlight, in order to obtain the results of the material’s weathering resistance. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and ...
Gloss is an essential component of how our eyes interpret the shape and form of things. The finish of a product, its texture, as well as the way a sample is lighted and seen, may all have an effect on the impression of gloss. Surfaces that have a high reflectivity are viewed as being glossy, shiny, or lustrous, while surfaces that have a lower reflectance are regarded as having a semi-gloss or mat...
A luminance meter can be used in lighting engineering to measure the brightness and color temperature of light sources, allowing for better design and adjustment of lighting schemes. Manufacturers of light sources and emitters can use photometers to verify the performance of their products, ensuring that the brightness and colors meet requirements. In film and television production, photometers ca...
The principle of UV aging test chambers: The ultraviolet weather resistance test equipment is another type of light aging test equipment that simulates sunlight, mainly simulating ultraviolet light in sunlight. At the same time, it can also reproduce the damage caused by rainwater and dew. The device conducts the experiment by exposing the material to sunlight and placing it in a controlled inter...
DC electronic load is an electronic switch device which draws DC power and transfers, stores or supplies to the grid with its terminal input characteristics conforming to Ohm’s law. It can also be used in ATE or ATS systems, including creating simulated wave shapes to test the power supply specs and characteristics, and even monitoring the battery usage or testing the power electronic compon...
Methods to test anti -aging and light stability often cause controversy. Over the past few years, all kinds of methods have been applied. Now most researchers have used natural exposure methods, Q-SUN Xenon arc lights or QUV accelerate aging test equipment. There are many advantages of natural exposure testing methods, which are practical, cheap, and easy to operate. However, most manufacturers ar...
The principle of withstand voltage test: Withstand voltage test, also is called dielectric voltage withstand test, is a testing method for measuring the conducting performance of a device and its resistance to high voltage charge damage, mainly used for detecting electrical safety. It can be used for both regular circuit products and prototype for new development, providing guarantee for further ...
Introduction Surges, also known as sudden voltage spikes, pose a significant threat to electrical systems because they have the potential to inflict damage to sensitive gear and cause production to come to a stop. Surge generators are required in order to test and assess the efficacy of different surge suppression systems that provide protection against the aforementioned voltage anomalies. In th...
