5 gallon paint bucket precautions

- Apr 28, 2019-

A 5 gallon paint bucket is used to fill the liquid, based on the specific gravity of the product, but must be left at 10% of the space required for the product to expand, to prevent the 5 gallon paint bucket from falling during handling. Deformation cracking. If it is used to fill low-boiling products, it is necessary to fully consider the vapor pressure of such products at a certain temperature, and the liquid vapor pressure increases with increasing temperature.

 

Also consider the product filling temperature and the 5 gallon paint bucket after filling may encounter the highest temperature during storage and transportation, as usual, 55 ° C should be considered, in some areas to consider the temperature difference between 60 ° C, causing products The expansion causes the internal pressure to be generated in the 5 gallon paint bucket. The sum of the two pressures cannot be greater than the allowable internal pressure in the paint bucket, otherwise the barrel will burst and strain.

 

If a 5 gallon paint bucket is used to fill the product at a higher temperature, consider the lowest temperature for storage and transportation. The temperature difference causes the paint bucket to generate a negative pressure, which may cause the 5 gallon paint bucket to suck, or the bucket to collapse. If possible, the product should be cooled to room temperature and refilled before being installed. If the product cannot be cooled and needs to be filled, the filled 5 gallon paint bucket cannot be tightened immediately. When the temperature of the cargo in the bucket drops to normal temperature, The lid is tightened.
