The deformation of the plastic bucket will directly affect the service life and delay our application. Plastic bucket mould manufacturers will tell you how to extend its service life and how to prevent deformation?
There are two possibilities for the deformation of the plastic bucket: the quality is not good, and the related problems are not paid attention to when using it;
Due to the quality problems of plastic drums, the problem of deformation is still relatively small, and current plastic drum manufacturers should conduct careful inspections before supplying them to the outside world. Therefore, its deformation problem is more related to the items they contain and the location and angle of the items.
When we use plastic drums to pack bulk goods, sometimes the drums are more likely to deform. There is an interesting statement by his deformation because the plastic bucket has good sealing performance, so when the plastic bucket is filled with liquid objects, the plastic bucket is airtight after the lid is tightened.
Generally, the high heat that plastic barrels can carry is less than 108 degrees, and the low heat is minus 70 degrees. Therefore, under normal circumstances, the temperature of liquid carried by plastic barrels should be minus 40 degrees to minus 60 degrees. . If it exceeds this value range when the device weighs heavier or has a higher temperature liquid, protective measures should be taken to prevent the plastic barrel from deforming. The plastic barrel obstruction inspection regulations stipulate that it must be sealed and airtight. If the liquid contained in it is dangerous, the plastic barrel required for category I dangerous goods must be able to withstand a pressure of 30Kpa/cm2, and for category II and III dangerous goods, The plastic barrels to be contained should also be able to withstand a pressure of 20Kpa/cm². The more sealed and airtight the plastic bucket, the easier it is to deform. This is a conceptual error.
Therefore, when the internal liquid is cooled, the pressure in the barrel becomes smaller and the external pressure becomes larger, resulting in a pressure difference between the inside and the outside of the barrel, resulting in deformation of the plastic barrel. This is a conceptual error. In the production formula, the pressure that the plastic barrel can withstand should be determined according to the dangerous degree of the liquid in it, and it will not be deformed by pressure.
It is often believed that the plastic barrel is deformed because of its good sealing. After the plastic barrel is filled with liquid goods and the lid is tightly screwed, it is airtight, so when the liquid inside is cooled, the pressure in the barrel becomes smaller. The large external pressure causes the pressure difference between the inside and outside of the barrel, which causes the plastic barrel to deform. The more sealed and airtight the plastic bucket, the easier it is to deform. This is a conceptual error. The plastic barrel obstruction inspection regulations stipulate that it must be sealed and airtight. If the liquid contained in it is dangerous, the plastic barrel required for category I dangerous goods must be able to withstand a pressure of 30Kpa/cm2, and for category II and III dangerous goods, The plastic barrels to be contained should also be able to withstand a pressure of 20Kpa/cm².
