近几年,铝制的锅碗盆匙等等日常生活用品越来越多。铝也被大家习惯的叫做“钢精”或“钢种”。铝和钢铁、搪瓷有下同的特性,所以,我们使用它时,就不能和铁的、搪瓷的制品一样对待。铝在空气中会生成一层薄薄的氧化铝膜,因而使铝的表面变暗;这层膜很坚实,可以保护里面的铝不再破氧化侵蚀。有些人不满意钢精锅子暗淡无光的外表,而用炉灰使劲刮擦,企图把它打磨得重现光辉。这实在是好心做蠢事,希望今后不要再这样擦。
In recent years, there have been more and more daily use items such as aluminum pots, bowls and spoons. Aluminum is also known as “steel fines” or “steel types”. Aluminum and steel, enamel have the same characteristics, so when we use it, we cannot treat it like iron and porcelain ware. Aluminum produces a thin layer of aluminum oxide in the air, which darkens the surface of the aluminum. This layer of film is very solid and can protect the inside of the aluminum from oxidative attack. Some people are dissatisfied with the dull appearance of the steel pot, and use the dust to scrape it hard in an attempt to reproduce it with glory. This is really a foolish thing to do. I hope that we will not do it in the future.
