Application of Peek Backup Ring Resistant to Electromagnetic Radiation in High Temperature Microwave Oven
1. Advantages of high temperature resistance:
-The high-temperature microwave environment is hot, and the PEEK backup ring can withstand 260 ℃ for a long time and 300 ℃ for a short time. It can stably backup components and ensure equipment operation near high temperature areas such as heating elements.
2. * * Electromagnetic radiation resistance characteristics * *:
-Microwave ovens emit strong electromagnetic radiation, and PEEK backup rings can shield interference without affecting themselves. Next to the magnetron, they provide stable backup for transmission and backuping components, ensuring heating and stability.
3. * * Mechanical Performance Guarantee * *:
-PEEK backup ring has high strength, with a tensile strength of about 90-100MPa. It can withstand pressure and load, and can reliably backup key components during high-temperature microwave operation and heating, preventing displacement and damage.
4. * * Dimensional stability * *:
-The PEEK backup ring maintains stable dimensions at high temperatures, with a thermal expansion coefficient of approximately 4.7 × 10 ⁻⁵/℃. It undergoes heating and cooling cycles in a microwave oven, resulting in minimal dimensional changes. At the door shaft, it ensures smooth door opening and sealing.
5. * * Chemical stability * *:
-There is a small amount of water vapor and acidic/alkaline substances in the microwave oven. The PEEK backup ring is chemically stable and resistant to these substances. Near the steam discharge channel, it is corrosion-resistant, deteriorated, and has a long service life and performance.
