How to reduce air contact and extend the life of paint by improving the design of paint buckets?
Publish Time: 2025-05-19
During the storage process, paint will gradually solidify or deteriorate when it comes into contact with oxygen in the air, which not only affects the use effect of the paint, but may also lead to waste. Therefore, improving the design of paint buckets to reduce air contact has become one of the key measures to improve the shelf life and quality of paint.
1. Application of vacuum sealing technology
Vacuum sealing is a very effective way to prevent paint oxidation. By integrating a small manual pump or other form of air extraction device in the paint bucket cover, users can extract the air in the bucket after each use to form a near-vacuum state. This method greatly reduces the chance of paint contact with air, thereby effectively delaying the aging process of the paint.
2. Automatic exhaust valve design
Some advanced paint bucket designs incorporate automatic exhaust valves. This valve allows the pressure in the bucket to be released when the paint is taken out, and prevents outside air from re-entering the bucket when it is closed. This method can ensure easy access, minimize air residue, and protect the paint from contamination.
3. Liner bag system
Introducing liner bags is also an innovative solution that has become popular in recent years. Liner bags are usually made of materials with good barrier properties, such as aluminum foil composite films. When paint is placed in such liner bags and then placed in paint buckets, it can effectively isolate the direct contact between the paint and the external environment. After each use, simply squeeze out the excess air to achieve a good sealing effect.
4. Partitioned storage design
For paint buckets with larger capacity, partitioned storage is also a feasible strategy. That is, the paint is stored in several small areas, and only the required part is opened each time. The advantage of this is that even if a part of the paint is exposed to the air and begins to cure, it will not affect the quality of the remaining unopened parts.
5. Improve the opening size and sealing method
It is also important to optimize the opening size of the paint bucket and use higher-grade sealing materials. For example, reducing the opening diameter can reduce the exposed area of the paint surface; using high-performance rubber rings or other elastomers as seals can enhance airtightness and prevent air infiltration.
Through the above-mentioned various design improvements, we can significantly reduce the possibility of paint coming into contact with air during storage, thereby extending its service life and keeping it in optimal condition. Whether it is using high-tech means or simple structural improvements, the goal is to provide users with a better and more durable product experience.
