Some skills and methods to avoid plastic barrel deformation

1. Generally, the highest heat that a plastic barrel can carry is less than 108 degrees, and the lowest 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. More appropriate. If it exceeds this value range, when the device weighs heavier or has a higher temperature liquid, protective measures should be taken for the plastic bucket to avoid deformation of the plastic bucket.

2. The plastic barrel obstruction inspection regulations clearly stipulate that it must be sealed and airtight. If the liquid contained in it is dangerous, the plastic barrel for dangerous goods in category I must be able to withstand a pressure of 30Kpa/cm2, while in category II and III The plastic barrels required for dangerous goods must also be able to withstand a pressure of 20Kpa/cm². The more sealed and airtight the plastic bucket, the easier it is to deform. In fact, this is a conceptual error. The machines used in the manufacture of plastic barrels in my country are relatively backward and have fewer wall thickness control points, resulting in unevenness in the barrel body. Therefore, the standard for plastic barrels is also relatively loose. The two symmetrical wall thicknesses are allowed to be 2:1. Within range. In this way, a plastic bucket with uneven wall thickness will often be judged qualified when it is subjected to anatomical analysis. In actual use, the plastic barrel will be deformed due to the large difference between the thickness of the barrel wall.
