Tips and methods for preventing plastic barrel deformation

1. Generally, the highest heat that plastic drums can carry is 108 degrees, and the lowest heat is minus 70 degrees. Therefore, under normal circumstances, the temperature of the liquid carried in plastic drums should be more than minus 40 degrees to minus 80 degrees. If the liquid contained exceeds this value range, if the device weighs more or the liquid is at a higher temperature, protective measures should be taken for the plastic bucket to avoid deformation of the plastic bucket.

2. Plastic barrels hinder the inspection regulations clearly stipulate that plastic barrels should be sealed and airtight. If the liquid inside is a dangerous product, then the plastic barrels required for Class I dangerous goods must be able to withstand the pressure of 30Kpa / cm2, while Class II The plastic drums required for Class III dangerous goods must also be able to withstand a pressure of 20Kpa / cm2. The more sealed the plastic bucket is, the more airtight it is, the easier it is to deform. In fact, this is a conceptual error. The machines used to manufacture plastic drums in China are relatively backward, and the wall thickness control points are few, resulting in uneven barrel body. Therefore, the standards for plastic drums are also loose. Relatively symmetrical two-point wall thicknesses are allowed at 2: 1. Within range. Such plastic barrels with uneven wall thickness will often pass the anatomy analysis. In actual use, the plastic barrel will be deformed because the thickness of the barrel wall varies greatly.
