Why is vacuum pumping necessary in the production of stainless steel water bottles?

I. What is vacuum pumping?

Vacuum pumping is a key step in the production process of stainless steel water bottles. It is a process that is completed by placing the stainless steel double-layer water bottle in a vacuum furnace and using a vacuum pump to remove the air between the layers. The complete process includes exhaust and sealing, where the vacuum effect is achieved between the double layers after exhausting, and then sealed to maintain a long-term vacuum state.

The role of “vacuum pumping” is to block the temperature conduction, so that the water cup can have a higher heat preservation effect. It is the most important process for whether the water cup can keep warm and for how long. The better the effect of vacuum, then the double-layer stainless steel bottle of thermal insulation performance is also the better. By controlling the vacuum pumping time, temperature, and pressure, the heat preservation effect and duration of the water bottle can be controlled. Increase the length of the water bottle heat preservation and some other auxiliary processes, but “vacuum pumping” is the premise, in the absence of vacuum process, any auxiliary processes can not be very good stainless steel water bottles have a good heat preservation effect. In the process of making stainless steel water bottle, vacuum pumping can effectively remove the oxygen and other impurities inside the bottle, so that the bottle is in a vacuum state, so as to ensure the purity and sealing of the bottle inside.

II. What are the steps of vacuum pumping?

The steps of vacuum pumping usually include the following:

1. Placement of the object. Place the object to be vacuumed in the vacuum chamber, usually paying attention to the position and direction of the object to fully utilize the space of the vacuum chamber.

2. Pumping. Use mechanical pumps or molecular pumps and other equipment to pump out the gas in the vacuum chamber until the required vacuum level is reached. During the pumping process, the pumping speed and vacuum degree need to be controlled to avoid damage to the object.

3. Maintain the vacuum state. Once the required vacuum level is reached, it needs to be maintained for a period of time so that the gases and impurities inside the object are completely removed. During the maintenance of the vacuum, the temperature and pressure of the vacuum chamber need to be controlled to avoid damage to the object.

4. Restore air pressure. After the vacuum treatment is completed, the air pressure inside the vacuum chamber needs to be restored gradually, so that the pressure inside the object is gradually restored to the normal level. In the process of restoring air pressure, it is necessary to control the speed and pressure to avoid damage to the object.

III. What is the purpose of vacuum pumping?

The benefits of vacuum pumping mainly include the following aspects:

1. Removal of gases and impurities. Oxygen and other impurities inside the stainless steel water bottle will have an impact on the quality and use of the bottle. Vacuum pumping can effectively remove the gas and impurities inside the object, thus ensuring its purity and quality.

2. Improve the sealing. Vacuum pumping can make the inside of the object in a vacuum state, which improves its sealing and avoids the dissipation of heat and gas.

3. Improve corrosion resistance. The material of stainless steel water bottle has corrosion resistance, but it may be affected by oxidization during the production process, resulting in a decrease in its corrosion resistance. Vacuum pumping can effectively remove oxides and improve the corrosion resistance of stainless steel water bottles.

4. Improve the appearance quality. Vacuum pumping can make the appearance of stainless steel water bottles smoother and flatter, avoiding bubbles and unevenness, improving the appearance of stainless steel water bottles.

In short, vacuum pumping is a very important step in the production process of stainless steel bottles. Vacuum pumping can remove oxygen and impurities, improve sealing and corrosion resistance, but also improve the appearance of stainless steel water bottle quality. Therefore, when buying stainless steel water bottles, consumers can pay attention to whether the bottles have been vacuumed to ensure their quality and use.
