The difference between yellowing resistance and UV aging test box?

There are often customers who are curious and confused about the aging test chamber of the environmental test chamber. Aging test chamber why is not a kind? Why are there so many types of aging test chambers? What is the difference between various aging test chambers?


QINSUN instrument production and sales of aging test chamber types are: xenon aging, yellow aging, UV aging, ozone aging, high and low temperature aging, temperature and humidity aging, salt spray aging, steam aging, sand and dust aging, rain type aging, etc..


Here to explain the difference between yellow aging test box and UV aging test box?

Yellow aging test chamber and UV aging test chamber and xenon lamp aging test chamber is the most confusing equipment, today only the difference between yellow aging test chamber and UV aging test chamber.


Anti-yellowing aging test box:

Two kinds of tests can be done: aging and yellowing resistance. It has two functions: one is high temperature aging (without bulb), the other is a separate UV300W bulb for yellow resistance test.

Also called UV aging chamber, UV using Perspex ultraviolet (UV) lamps to simulate the effect of sunlight exposure, using cold proposed moisture rain and dew. UV aging is able to match three kinds of lamps UV-A340, UV-B313,UV-A315, wavelength, irradiation intensity are different can be controlled, simulating the natural weather caused by the sun, rain and dew on the material.

Can do two kinds of testing: aging and yellowing resistance. It has two functions: one is high-temperature aging (no bulb), a separate UV300W bulb for yellowing resistance test.


Summary: yellow aging test chamber it simulates is a kind of indoor light, and no outdoor condensation and other effects, while the UV aging test chamber really simulates to the sun, rain and dew on the material caused by natural weather and other hazards. Although the two are similar. But the UV aging is a little more powerful. Users can choose according to their actual needs.
