Surface testing of non-metallic materials by ultraviolet aging test box

When ultraviolet rays are irradiated to the surface of non-metallic materials, free electrons inside the non-metallic materials will escape the surface, and the photoelectron emission of such ultraviolet rays forms part of the photoelectric effect of ultraviolet rays. The photoelectric effect of ultraviolet rays is a way of converting light energy into electrical energy. The photoelectric effect is divided into external photoelectric effect, internal photoelectric effect and photovoltaic effect. In addition to metals and semiconductors, materials that can produce a photoelectric effect by ultraviolet irradiation also have certain gases and some chemical substances. People and animals and plants can also produce photoelectric effects after being irradiated. At present, we can conduct tests through the ultraviolet light weather resistance test box, which can accurately test the performance and pass rate of non-metallic materials. The ultraviolet light weather resistance test box uses fluorescent ultraviolet lamps as the light source, by simulating ultraviolet radiation and condensation in natural sunlight , Accelerate the weather resistance test on the material to obtain the result of the material weather resistance. It can simulate the environmental conditions of ultraviolet, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in the natural climate. By reproducing these conditions, they are combined into a cycle and let it automatically complete the number of cycles.

SIZE MATTERS - BE THE ENVY OF YOUR BUDDYS - Don`t be judged by the length of your handle, there's no need to get too close to that roaring fire as you turn and handle your cuts of meat and veg like a pro! 
NO MORE BURNT ARM HAIR -  The quality design allows for easy handling at safe distances from the flame. The varying size gives your tong set the versatility all great grill masters look for in their tools!
SAVE YOUR MONEY AND YOUR MEAT - Buy 2 lengths of tong you`re gonna use, rather than 1 you`re not. It's easy to purchase the first thing that looks ok, but, he or she who buys cheap buys twice! The quality is apparent and the ease of use a BBQ geeks dream!

LOOK THE PART AND KEEP THE TONGS - It's important to know what your doing come meal time and the first rule of barbecue is to not cross contaminate by turning your chicken and then your steak for example - Protect your reputation when cooking up a storm and throwing awesome backyard parties. You're the King now!
