1. The outer cover of the chemical plastic barrel equipment needs to be tightened by external force (can be tightened by the torque wrench). After the sealing ring equipment, it is necessary to closely contact the surface of the barrel mouth to prevent the sealing ring from misunderstanding the equipment.
2, assuming that the temperature of the filling product is higher than 40 °C, it is necessary to cool the outer cover and the stacking code at the product temperature to cool to normal temperature; the stacking should pay attention to the stacking of the code, the contact area of the bottom layer of the stacking code is the largest, the upper layer Correction, repelling misplaced stacking; this can avoid deformation of chemical plastic barrels.
3, assuming that the filling product is prone to volatile gases, especially in the 7th, 8th and 9th months when the temperature difference effect is significant, the filling should be selected at the lowest temperature of the day to avoid the deformation of the concave.
