木质包装集装箱溴甲烷检疫熏蒸技术研究

Methyl bromide fumigation of wood packing material for the quarantine treatment in the container.

对集装箱装运的出口货物木质包装进行了溴甲烷熏蒸试验 ,结果说明 ,当环境温度为 2～ 1 6℃时 ,采用溴甲烷投药剂量 80 g/m3 ,熏蒸 2 4h能够全部杀死黄斑星天牛幼虫 ,其CT值为 1 1 2 5 8～ 3345 3g h/m3 ;环境温度为 5～ 2 0℃时 ,采用 6 4g/m3 投药剂量 ,同样熏蒸 2 4h ,CT值为 1 2 1 0 8～ 1 51 0 8g h/m3 ,黄斑星天牛幼虫同样全部死亡。溴甲烷汽化后直接从集装箱门上部投药能够使药剂分布均匀。熏蒸结束后通风散气 2 4h ,集装箱到达美国后其内部溴甲烷残留气体浓度低于 5× 1 0 -6。

Wood packing material was fumigated with methyl bromide (MB) in the container, Anoplophora nobilis in the popular was all dead when fumigated with MB at the dosage of 80g/ m 3 at the temperatures of 2～16℃, or at the dosage of 64g/ m 3 at the temperatures of 5～20℃. The CT products in the containers were 1125 8～3345 3g h/ m 3 and 1210 8～1510 8g h/ m 3 respectively. The gas of MB can be distributed evenly when the fumigant was dosed from the top of the Container after evaporation. The container was aerated for 24 hours, and the residue of MB concentration was lower than 5×10 -6 g/ m 3 when the container arrived the port of Long beech from Tianjin.
