干电池、白炽电灯和日光灯是最普通的用电器。在家庭里、在实验室里,到处可以找到这些废旧料。这些东西还能有用吗?在学校深入开展“第二课堂”活动中,这些废旧料找到了出路,现就我们的一些做法,简单介绍如下。一、制作方法(废料加工后备用) (1)废灯泡的加工处理①用较大功率(75W以上)的电烙铁,将灯泡(卡口的)尾部的锡和密封物质搞掉。②小心将灯泡中间的玻璃柱芯取出,去掉上面的钨丝,留下玻璃柱芯及两根金属丝,如图1所示。③将玻璃泡洗干净,然后
Dry batteries, incandescent lamps and fluorescent lamps are the most common appliances. In the home, in the laboratory, these wastes can be found everywhere. Can these things still be useful? In the school’s in-depth “second class” activities, these waste materials have found a way out. Now we briefly introduce some of our practices. First, the production method (stand-by after waste processing) (1) waste lamp processing 1 use a large power (75W or more) of the electric iron, the bulb (collar) tail tin and sealing material out. 2 Carefully remove the glass core from the middle of the bulb, remove the tungsten wire, leaving the glass core and two wires, as shown in Figure 1. 3Wash the glass bubble, then
