　　3、 Vacuum system

　　Vacuum degree: 0~-101KPa (≤ 133pa)

　　Vacuum pressure leakage rate: approximately 0.8KPa per hour

　　Using high sealing silicone sealing strips to ensure the sealing of the entire machine;

　　Using a digital display vacuum gauge to directly display the vacuum degree inside the box, allowing you to instantly understand the vacuum status inside the box. The vacuum degree reaches 0-0.1Mpa (i.e. 100pa vacuum degree)

　　1Double layer vacuum ovenWorking Principle:

　　1.1 The boiling point decreases with the decrease of air pressure. The boiling point of water significantly decreases under negative pressure, and when the pressure drops to -0.089Mpa, the theoretical boiling point can drop to 45 ℃. In a negative pressure environment, water is more easily vaporized.

　　1.2 After heating the lithium-ion oven at atmospheric pressure for a period of time, the moisture in the battery or electrode piece is converted into water vapor; After the evaporation of water, vacuuming can extract the water vapor; Fill nitrogen to break the vacuum and maintain a dry environment. In the actual baking process, the order of the above three steps varies according to different processes, and generally requires multiple cycles.
