化学实验中常用的热源为酒精灯,火焰温度一般在500℃左右,达不到一些实验所需高温,而酒精喷灯使用又比较复杂,如何解决这个问题呢?笔者使用市面上常见的气体烙铁,可以顺利完成一系列高温实验。气体烙铁是从打火机的便携和煤气灶的持续燃烧特点出发,在打火机的基础上增加空气入口和防回火装置,在顶端加内嵌式燃烧盘(见图1)。利用丁烷燃烧可达1300℃高温——化学实验中不可多得的高温热源。 Commonly used in chemical experiments for the alcohol heat lamp, the flame temperature is generally about 500 ℃, less than some experiments required high temperature, and the use of alcohol torches and more complicated, how to solve this problem? I use the market commonly used gas iron, Can successfully complete a series of high temperature experiments. The gas soldering iron is based on the portable lighter and the continuous burning of the gas stove. The air inlet and anti-tempering device are added on the basis of the lighter, and the embedded combustion disk is added on the top (see Fig. 1). Using butane combustion up to 1300 ℃ high temperature - chemical experiments rare high temperature heat source.
