The global environmental protection situation is becoming more and more serious, and global warming is becoming more and more serious. Each of us has probably already tasted the consequences of global warming, and countries around the world are currently developing and implementing their own carbon dioxide emissions reduction plans in an attempt to "cool" the planet. Today, Weavers Xiaobian brings you an article by Mr. Lin Mengru, a scholar from Taiwan, on global carbon dioxide concentration and

How does sulfur hexafluoride cause its harm? It is important to know that there are many industries that need to use SF6 gas, and there are many manufacturers that produce SF6 gas, which are possible emission sources of SF6 gas, and the harm of sulfur hexafluoride is also accompanied by these emission sources. For example, if the manufacturer of SF6 gas is poorly managed in the production process and the technology is immature, it is very likely to lead to the discharge of SF6 gas in the product

Sulfur hexafluoride was a colorless, odorless, non-toxic, and non-flammable stable gas. Its molecular weight was 146.07. Its density was 6.1kg/m3 at 20℃ and 0.1 MPa, which was about 5 times the density of air. Sulfur hexafluoride is a gas at normal temperature and pressure, and its critical temperature is 45.6℃, the triple point temperature is -50.8℃, and the sublimation point temperature is -63.8℃ under normal pressure. Sulfur hexafluoride has octahedral configuration, small bonding distance an

From the basic physical characteristics of SF6 gas, it can be seen that it is relatively easy to liquefy gas compared with air. The state of SF6 gas depends on parameters such as its pressure and temperature. The critical temperature is the highest temperature at which a gas can be liquefied. The lower the critical temperature, the less likely the gas is to be liquefied. The critical temperature of SF6 gas is 45.6 ° C, indicating that the temperature is higher than 45.6 ° C in order to mainta
