[Plastic Hardware Network] The research team of the Fujian Institute of Physics, Chinese Academy of Sciences recently synthesized a new type of palladium nano-catalyst using Cu(II) ion-assisted in-situ reduction at room temperature. The catalyst has an ultra-low precious metal loading (about 0.1%) and excellent performance. , Long life, can greatly reduce the cost of catalysts and save a lot of precious metal resources. After the catalyst is successfully prepared, it is expected to form a new generation of coal-to-ethylene glycol catalyst technology. Coal-to-ethylene glycol technology can not only effectively alleviate the contradiction between the supply and demand of ethylene glycol in my country, but also improve the level of efficient and clean conversion and utilization of coal resources. The reaction of CO gas-phase oxidative coupling to dimethyl oxalate is a key step in the production of ethylene glycol from coal. The currently used catalysts have a relatively high loading of palladium, which greatly increases the cost of the catalyst. More related information:
Dalian Plastics Futures opened low and moved high on the 23rd. The main 1305 contract closed at 9880 yuan/ton, up 55 yuan. The recent performance of Liansu 1305 is relatively resilient, temporarily forming a short-term bottom at 9700. Geopolitical factors have affected the recent sharp fluctuations in crude oil. With the easing of the conflict, crude oil is still dominated by weakness in the later stage, while the fundamentals of continuous plastics are still weak, and the upstream cost factors continue to weaken.
The cable tie, as the name implies, is a strap for binding things. It is designed with a stop function and can only be tied tighter and tighter. There is also a detachable cable tie. There are also releasable cable ties for easy use. Divided into metal cable ties (usually stainless steel materials) and plastic ties (usually nylon materials), commonly used in electrical and mechanical cables, computers, electronic products, automotive wiring harnesses, etc.
