厨房是每个家庭都不可缺少的。不知您是否留意,厨房的灯具特别容易坏,往往新装的灯具,使用不过半年,灯头就出现了锈斑,开关接触不良,甚至已经锈蚀得无法使用。原来这是由于使用煤炉时,煤炭燃烧产生的二氧化硫等酸性气体对金属制品及电器会产生极其严重的腐蚀作用。特别是晚上将炉子用湿煤灰封盖过夜,将产生更多的腐蚀性气体。天长日久,炉灰和腐蚀性气体进入灯头和开关中,降低了其内部的绝缘能力,造成漏电、跳火、短路等现象。 The kitchen is indispensable for every family. I wonder if you have noticed that the kitchen lighting is particularly prone to damage, and new lighting fixtures are often used for only six months. The lamp head has rust spots, poor contact with the switch, and even rust may not be used. It turns out that because of the use of coal stoves, sulfur dioxide and other acid gases produced by the combustion of coal have extremely severe corrosive effects on metal products and electrical appliances. Especially at night, the furnace is covered with wet coal ash overnight and more corrosive gas will be produced. As time goes on, furnace ash and corrosive gases enter the lamp caps and switches, reducing their internal insulation capabilities, resulting in leakage, flashover, short circuit and other phenomena.
