摘　　要：研究的网状铝合金材料主要用于汽车加油(气)站、轻质燃油和液化石油气汽车罐车用储罐阻隔防爆。甲醇汽油对铝、铅、铸铁合金等金属材料都有腐蚀作用,应用于储存甲醇汽油的储罐时必须考虑甲醇汽油对材料的腐蚀性。参考GB/T 378和GB/T5096,测定了不同型号的甲醇汽油对网状多孔铝合金材料的腐蚀情况,得到了材料的腐蚀率及单位面积的腐蚀质量,结果表明甲醇汽油对材料的腐蚀率都在1%以下;甲醇汽油中加入防腐剂后,腐蚀率和单位面积的腐蚀质量大大降低,甚至不腐蚀,为材料的使用提供参考。The mesh aluminum alloy material is mainly used for blocking explosion-proof in filling station,light fuel and liquefied petroleum gas tanker.Methanol gasoline can corrode aluminum,lead,cast iron alloys metal materials and so on,the corrosion must be taken into account when material used in storage methanol gasoline.In this paper the corrosion of different methanol gasoline to mesh aluminum alloy material was determined and get the corrosion rate and corrosion quality in unit area were obtained by referencing GB/T 378 and GB/T5096.The results showed that the corrosion rate of methanol gasoline to material was below 1%;corrosion rate and corrosion quality in unit area greatly reduced or even not corrosion after adding methanol gasoline preservatives,besides it provides reference for the use of material.
