Nitrogen introduction [ 2020-09-02 ]
The chemical formula is N2, which is usually a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen accounts for 78.08% (volume fraction) of the total atmosphere and is the main component of air. Under standard atmospheric pressure, when cooled to -195.8°C, it becomes a colorless liquid, and when cooled to -209.8°C, liquid nitrogen becomes a snow-like solid. Nitrogen is chemically inactive and difficult to react with other substances at room temperature, so it is often used to make preservatives. However, it can undergo chemical changes with certain substances under high temperature and high energy conditions to produce new substances useful to humans.
PTFE Introduction [ 2020-09-02 ]
Tetrafluoro is a polymer of tetrafluoroethylene. The English abbreviation is PTFE. The basic structure of polytetrafluoroethylene is.-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2 -. Polytetrafluoroethylene is widely used in various applications that require resistance to acids, alkalis and organic solvents. It is not toxic to humans, but perfluorooctanoate (PFOA), one of the raw materials used in the production process, is considered to have carcinogenic effects.
