    • The invention relates to a process for reducing the residual hydrogen fluoride gases in a fluorinated plastic tank, in particular in a plastic tank for a motor vehicle, in which firstly the space within the tank is subjected to a fluorination step and then, in at least one gas flushing process, the reaction products of the fluorination step are removed from the plastic tank. In a process in which the undesired reaction product hydrogen fluoride is completely eliminated and which is suitable for efficient large-scale production, after the gas flushing process, a neutralization step is carried out to bind residual fluorination gases on the inner layers of the plastic tank.
    • 本发明涉及一种用于减少氟化塑料罐中的残余氟化氢气体的方法,特别是用于机动车辆的塑料罐中,首先将罐内的空间进行氟化步骤,然后至少在 一个气体冲洗过程,氟化步骤的反应产物从塑料罐中取出。 在不需要的反应产物氟化氢完全消除并适合于高效大规模生产的过程中,在气体冲洗过程之后,进行中和步骤以将残留的氟化气体结合在塑料罐的内层上 。
