网友“香氛天堂”问:我们最近正在学电学．我从网上看到,装汽油的罐子一般都是由金属做的,汽油站也规定不能用塑料桶装汽油．这是为什么呢? “渔舟唱晚”答:主要原因是汽油易燃,只要有一点火花就可能引起剧烈燃烧．在运输过程中塑料桶会与汽油、空气相摩擦,从而产生静电 Netizen “Aroma Paradise” Q: We are learning electricity recently. I saw from the Internet that gasoline canisters are generally made of metal. Gasoline stations also stipulate that gasoline cannot be used in plastic drums. Why is this? “Fishing Boat Singing Night” A: The main reason is that gasoline is flammable. As long as there is a little spark, it may cause fierce combustion. During the transportation process, the plastic bucket rubs against gasoline and air to generate static electricity.
