Sulfur hexafluoride gases are known by more and more people. Here I will share you about 3 uses of SF6 gases.
1. During the magnesium alloy process, sulfur hexafluoride gas or mixture gases (sulfur hexafluoride and nitrogen) often are used as a protective gas, whose purpose is to prevent the metal magnesium and alloys from air oxidation.
2. In the medical industry, sulfur hexafluoride is also used for ultrasound
contrast, mainly liver tumor angiography. In the course of contrast-enhanced
ultrasound, Sulfur Hexafluoride is mainly used as a safe contrast agent, after
the intravenous injection of sulfur hexafluoride, the gas dissolved in the
blood, every 12 minutes of sulfur hexafluoride gas can be discharged by
breathing half way.
3. The chemical stability of sulfur hexafluoride, molecular weight (sulfur hexafluoride molecular weight of 146.06), its density is 5.11 times the air, into the car tires or basketball, football, will be able to maintain long-term stability of air pressure.
