此次偏差的可能原因是车间取样人员因连续使用压盖器进行压盖出现间歇性乏力

The possible reason for this deviation is that the sampling personnel in the workshop have intermittent fatigue due to the continuous use of the capping device, resulting in insufficient force during the capping process and insufficient capping. (40 ± 2 ℃), methanol is heated and volatilized, forming a certain pressure, the rubber plug is pushed up, and methanol gas slowly volatilizes from the gap of the rubber plug. It is an accident.

此次偏差的可能原因是车间取样人员因连续使用压盖器进行压盖出现间歇性乏力，导致在压盖过程中用力不足、压盖不够充分，导致铝盖未压紧，在稳定性温度条件(40±2℃)下，甲醇受热挥发，形成一定的压力，胶塞被顶起，甲醇气体从胶塞缝隙处缓慢挥发。属于偶然事件。

The possible cause of this deviation is that the sampling personnel in the workshop are lack of force due to the continuous use of the capper to gland, resulting in insufficient force and gland during the gland process, resulting in the aluminum cover not being pressed tightly. Under the stable temperature condition (40 ± 2 ℃), methanol is volatilized by heating, forming a certain pressure, the rubber plug is jacked up, and the methanol gas slowly volatilizes from the gap of the rubber plug. It's an accident.<br>
