大量的金属制品是用木箱包装运输储存的。有时产品出厂后一直未开过箱便直接入库储存,箱中的金属也未与木箱直接接触,结果产生了严重的腐蚀,甚至比在箱外的腐蚀更为严重。至于与木材接触的金属就更不用说会产生接触腐蚀。 A large number of metal products are packed in wooden boxes for transport and storage. Sometimes the product has not been opened before leaving the box directly storage, the box metal is not in direct contact with the wooden case, resulting in serious corrosion, corrosion even worse than outside the box. As for the metal in contact with the wood, let alone produce contact corrosion.
