The stainless steel thermos cup is a beverage container we often use, and its excellent thermal insulation performance often comes from the vacuuming process. The following is the standard operating procedure for vacuuming stainless steel thermos cups and related precautions.
1. Preparation: Clean the stainless steel thermos cup and ensure that the sealing ring and various parts are intact.
2. Heating treatment: Place the stainless steel thermos cup into the preheating chamber for heating treatment. It is generally recommended to heat it to about 60°C.
3. Vacuuming: Place the heated stainless steel thermos cup into the vacuum machine, and connect the vacuum pump and cup body through pipelines. Open the exhaust valve and start vacuuming until the required vacuum level is reached.
4. Inflation: After completing the vacuuming operation, the inflation operation needs to be carried out quickly. This step can be carried out by directly introducing gas or by injecting inert gas first and then introducing air.
5. Check the quality: Conduct a visual inspection of the vacuumed stainless steel thermos cup to ensure that the sealing and vacuum degree meet the requirements.
It should be noted that during the process of vacuuming the stainless steel thermos cup, you need to pay attention to the following points:
1. During the air extraction process, it is necessary to ensure that the environment is clean and dry to avoid the impact of pollution and moisture on the vacuum degree.
2. The heating process needs to control the temperature to avoid damage or deformation of the stainless steel thermos cup itself.
3. It needs to be tested after inflation to ensure that the vacuum degree and sealing performance meet the requirements before it can be used with confidence.
4. Pay attention to safety issues. For example, if the vacuum pump cannot operate continuously for a long time, it is necessary to regularly check whether the equipment is operating normally, etc.
To sum up, the stainless steel thermos cup vacuuming process is an important production process, which requires strict compliance with standard operating procedures and attention to relevant operating specifications and safety matters. Only in this way can we ensure that the stainless steel thermos cup has excellent thermal insulation effect and reliable use quality.
