Polyvinyl chloride is also known as polyvinyl chloride. Polyvinyl chloride is a solid plastic made of vinyl chloride. PVC is the third most widely produced synthetic plastic polymer in the world, second only to polyethylene and polypropylene. PVC has a variety of applications such as building construction, healthcare, electronics, automotive and other industries. Because PVC products can range from pipes and sidings, blood bags and pipes, wire and cable insulation, windshield system components, etc. In general, PVC products are everywhere in our daily lives. Due to its wide range of applications, the recycling of PVC has become more important. PVC crusher is an indispensable equipment in the entire PVC recycling process.

LED is a type of light source that is currently favored on the market. It has better performance than traditional incandescent bulbs and has a longer service life. However, the phosphor of the white LED light source uses a rare earth element, and the main function is to emit a longer light wave from the LED chip, so that the bulb emits visible light of a full spectrum. The mining and processing of rare earths is quite dangerous. At present, China is the only country in the world to provide a considerable number of rare earths. The research team led by Prof. JingLi from Rutgers University in New Jersey is the LED light source. Successfully found an alternative solution. The research team has extracted a new alloy from a very cheap and abundant copper iodide that can replace the rare earth as a source of LED light. The most important thing is that this extraction method is relatively simple and cost-effective. In addition, by adjusting the color and intensity, it can adjust the white light that is warmer than the existing LED.
