用三层滤纸折成漏斗状,底部剪一小孔,把它放在铁架台的铁圈上润湿,下面放一盛砂用的瓦片,承受分离出来的铁水。把铝热剂倒入纸漏斗里,上面堆放一层新的引火剂,不需要镁条,在半分钟左右,反应就迅速发生,发出耀眼的强光,放出大量的热,生成的铁呈液态往纸漏斗底部的小孔里流出,滴到盛砂的瓦片上。 可以采用以下二种新的引火剂: 1.将氯酸钾、过氧化钠、硫磺粉以1:1:1的比例混和,堆放在铝热剂上,只要撒上少许铝粉,就能使反应自动进行。
Three-layer filter paper is folded into a funnel, a small hole is cut at the bottom, and it is placed on the iron ring of the iron platform to moisten, and a tile for sand is placed under it to withstand the separated molten iron. The aluminum heat agent is poured into a paper funnel and a new layer of ignition agent is stacked on top of it. No magnesium strips are needed. In about half a minute, the reaction takes place quickly, emitting dazzling light, releasing a lot of heat, and generating iron in liquid form. Flow out into the small hole at the bottom of the paper funnel and drop it onto the sanded tiles. The following two kinds of new priming agents can be used: 1. Potassium chlorate, sodium peroxide and sulfur powder are mixed in a ratio of 1:1:1 and stacked on aluminothermic agent. As long as a little aluminum powder is sprinkled, the reaction can be automated. get on.
