What is Carbon tetrafluoride CF4?
Carbon tetrafluoride CF4 is a colorless, odorless, non-toxic gas with the chemical formula CF4, which belongs to the halogenated alkane compound. Due to its low reactivity and excellent insulation properties, it is widely used as an insulating medium in power equipment, as an excitation gas in gas discharge tubes, and as a gas in electrode manufacturing in semiconductor production.
What is the filling factor?
The filling factor refers to the proportion of gas in the actual filling liquid at a certain temperature and pressure. The filling factor can reflect the density and liquefaction capacity of the gas. For carbon tetrafluoride, its filling factor is 0.99 at 20°C.
What are the factors that affect the filling factor of Carbon tetrafluoride CF4?
1. Temperature: The increase in temperature will expand the volume of the gas, resulting in a decrease in the filling factor.
2. Pressure: The increase in pressure can increase the density of the gas, thereby increasing the filling factor.
3. Container size and shape: The size and shape of the container will also affect the filling factor. Generally speaking, the smaller the container, the higher the filling factor.
4. Gas purity: The higher the gas purity, the higher the filling factor.
What issues should be paid attention to in the actual filling of Carbon tetrafluoride CF4?
1. Due to the pollution of carbon tetrafluoride to the environment and the harm to human health, its filling must be carried out under the protection of corresponding safety processes and safety facilities.
2. During actual filling, the filling factor needs to be adjusted according to the specific situation to ensure safety and filling efficiency.
3. During the filling process, it is also necessary to pay attention to parameters such as filling time, filling pressure and temperature to ensure the quality and safety of filling.
