We know that the quantification of color and light is in an abstract sense, so the differences in color and other physical differences are distinct. For example, when we use a measuring stick to measure the length of an object, people often arbitrarily divide it into uniform small segments. Even small lengths that cannot be distinguished by the human eye can be judged by measuring tools. But when ...
Electrical Safety Withstand Voltage Test Standards： Electrical Safety Withstand Voltage Test is an important indicator for measuring the insulation performance of electrical equipment, and its effective measuring standards are: For general test equipment, leakage current values between the spark wire and the shell can be measured, the basic standard requires two times the working voltage plus 10...
What is Hot Wire Test? Hot wire test is a common experiment methodology that is used to study the combustibility and thermal stability of materials. By placing the material above the hot wire and heating the hot wire, it is possible to evaluate the fire hazard and fire protection performance of the material by observing whether the material is ignited and the burning behavior after ignition. Prin...
The ozone aging test chamber is mainly used to study the action law of rubber, simulate and strengthen the ozone conditions in the atmosphere, and achieve rapid identification and evaluation of rubber’s ozone aging resistance performance and the protective effect of ozone agents; Furthermore, effective anti-aging measures are taken to improve the service life of rubber products. Usage of ozo...
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...
