Nitrogen-filled oven is a kind of heat treatment equipment using nitrogen filling technology. It is mainly used for drying, curing, heat treatment, sterilization and other operations of materials. Its nitrogen filling technology can effectively protect materials and equipment from oxidation and corrosion.
When choosing a nitrogen-filled oven, the following points and precautions need to be considered:
main points
Temperature control accuracy: The nitrogen-filled oven needs to be able to accurately control the temperature, and generally requires a control accuracy higher than ±1°C.
Temperature range: The temperature range of the nitrogen-filled oven should meet the experimental requirements, and the corresponding temperature range should be selected according to the experimental needs.
Oven volume: The oven volume needs to be selected according to the size and quantity of experimental samples to ensure that all experimental samples can be accommodated.
Nitrogen filling method: The nitrogen filling methods of the nitrogen-filled oven include unidirectional flow, circulating flow and alternating flow, etc. It is necessary to select the appropriate nitrogen filling method according to the experimental requirements.
Control method: There are two control methods: manual and digital. The digital control method can control the temperature and time more accurately. It is recommended to choose the digital control method.
Safety: The use of nitrogen-filled ovens needs to pay attention to safety, and it is necessary to choose equipment with safety protection measures, such as over-temperature protection, leakage protection, etc.
Precautions
Regular maintenance: The nitrogen-filled oven needs regular maintenance and maintenance, including cleaning and refueling, so as to ensure the normal operation and life of the equipment.
Safe operation: When operating a nitrogen-filled oven, you need to pay attention to safe operation to avoid accidents such as nitrogen leakage and burns.
Cleanliness and hygiene: The nitrogen-filled oven needs to be kept clean and hygienic to avoid problems such as sample contamination and equipment failure.
Sample preparation: When using a nitrogen-filled oven, it is important to pay attention to sample preparation and loading to ensure that the sample meets the requirements of the oven and is safely loaded inside the oven.
Monitoring the experimental process: During the experimental process, the temperature and time of the oven need to be monitored to ensure the accuracy and repeatability of the experiment.
Nitrogen pressure monitoring: When using a nitrogen-filled oven, you need to pay attention to the monitoring of nitrogen pressure
