The following introduces how to repair cracks in chemical barrels.

　　Plastic chemical barrels are essential items in daily life and are also very important liquid containers in industrial production. However, since plastic chemical barrels are made of plastic, they may occasionally develop cracks due to bumps. Here are some suggestions for repairing cracks in plastic barrels. First, before repairing, you need to know the size of the crack. If it is a large hole, use a clean piece of plastic slightly larger than the hole to cover it, and then use a welding gun to weld around the plastic. If it is a crack, you need to use a clean piece of plastic that is slightly longer and wider than the crack to bond it, and then press it down with a wet cloth for a stronger bond.

　　Chemical barrel plastics can be divided into thermosetting and thermoplastic. The former cannot be reshaped and reused, while the latter can be repeatedly produced. The polymer structure of plastics basically has two types: one is linear structure, and the polymer compounds with this structure are called linear polymer compounds.

　　The other is the body structure, and the polymer compounds with this structure are called body polymer compounds. Some polymers have branched chains, known as branched polymers, which belong to linear structures. Some polymers, although there are cross-links between molecules, have fewer cross-links and are called network structures, belonging to body structures.

　　How to prevent chemical barrels from deforming?

　　General chemical barrels can carry high heat of 108 degrees and low heat of minus 70 degrees, so the temperature of the liquid in the barrel should be between minus 40 degrees and plus 60 degrees. If it exceeds this range, when containing heavy or high-temperature liquids, protective measures should be taken to avoid deformation of the barrel.

　　Regardless of quality, latex paint barrels have a relatively large temperature resistance range. Once this application range is exceeded, the barrels are prone to deformation, aging, and other issues. Therefore, when using barrels to hold liquids, we should pay attention to whether the temperature of the liquid is controlled within the allowable range of the barrels.

　　How to prevent chemical barrels from being lost?

　　Preventive measures: Ensure that chemical barrels have suitable lids and are sealed. Regularly check the barrels for corrosion, swelling, defects, dents, and leaks. Place defective latex paint barrels in separate secondary packaging barrels or leak emergency barrels. Ensure that the latex paint barrels are compatible with their contents, such as not putting acid in ordinary iron barrels and not putting solvents in plastic barrels. Accurately identify waste latex paint barrels.

　　Secondary safety shell: The principle is to use secondary packaging for oil barrels that may leak to control possible leaks.

　　It must be ensured that the leakage capacity of the secondary container is at least 110% of the volume of the large container and 10% of the total volume of all oil barrels. All steel barrels, iron barrels, plastic barrels, ton barrels, kiloliter barrels, or other containers may be damaged during long-term transportation and use, leading to leaks.

　　That's all for today. I hope everyone has a further understanding of chemical barrels. If you need to purchase or customize chemical barrels, remember to consult our manufacturer.
