Paint can is a common form of packaging, this type of packaging not only preserves the paint well, but also promotes the sales of the product through the pattern and text on the bucket. In addition, the paint bucket can be reused and can be loaded with other materials after cleaning the used paint can. Therefore, the application of paint cans in the market is very wide and very popular. However, there are still some problems to be aware of when using the paint can. What issues should be paid attention to? The following will be a brief explanation of this problem.

1. Inspect each component before use and clean the paint bucket according to the situation to ensure that the paint bucket is in good condition.

2. The feeding amount should not exceed 2/3 (26L) of the volume of the paint bucket. Otherwise, the valve rubber of the pressure reducing valve may be damaged and the paint may be reversed; the coating may be contacted from the rotating shaft and the lid of the barrel.

3. No coating is allowed on the top 1/3 of the paint bucket, the paint bucket cover and the sealant pad. If it is, it will be cleaned immediately to ensure the sealing effect.

4, The working pressure of the paint bucket can be as high as 0.09Mpa (that is, 0.9Kgf/cm2), otherwise it is prone to danger.

5. Generally, the paint pressurization pressure is adjusted to 0.05Mpa (ie 0.5Kgf/cm2) for test spraying, and then the spray air pressure is changed little by little. If the paint can is long, the paint pressurization pressure can be slightly increased.
