慢镜头下的火柴点燃过程

How Do Matches Work?

当你点燃火柴时会发生什么?
TEXT ONSCREEN: What Happens When You Light a Match
火柴头的燃料是三硫化锑
The head of the match uses antimony trisulfide for fuel.
氯酸钾对燃料有助燃作用 这就是火柴点燃的关键
Potassium chlorate helps that fuel burn and is basically the key to ignition.
而磷酸铵防止火柴在熄灭的时候
While ammonium phosphate prevents match from smoking too much,
产生太多烟
when it’s extinguished.
石蜡有助于使火焰沿着木棒燃烧
Parrafin wax helps the flame travels down the wooden stick,
胶水将各部分固定在一起
and glue holds all the stuff together.
至于颜料 好吧 只是让它看起来好看
The Dye… well, that just makes it look pretty.
在火柴头表面上
On the striking surface,
有用于摩擦的玻璃粉和用于点火的红磷
there’s powdered glass for friction and Red phosphorous to ignite the flame.
现在有趣的来了
Now the fun stuff.
火柴头和火柴盒上的玻璃粉产生摩擦
Striking a match against the powdered glass on the matchbox creates friction.
摩擦产生的热量将红磷转变为白磷
Heat from this friction converts the red phosphorus into white phosphorus.
白磷极其活泼 能和空气中的氧气反应
White phosphorous is extremly volatile and reacts with oxygen
从而开始燃烧
in the air, causing it to ignite.
所有热量点燃氯酸钾 产生你所看到的火焰
All this heat ignites the potassium chlorate, creating the flame you see here.
氧化剂 比如氯酸钾 通过产生更多氧气促进燃料燃烧
Oxidizers,like potassium chlorate, help fuels burn by giving them more oxygen.
氧气和三硫化锑燃料结合
This oxygen combines with sulfur Antimony trisulfide, the fuel,
产生更持久的火焰
to produce a longer-lasting flame, so
所以大家有足够的时间点燃蜡烛
you have enough time to light a candle.
整根火柴都涂有石蜡
The entire match is coated with paraffin wax,
它们使火焰沿着火柴棒燃烧
which helps the flame travel down the match.
小心别把房子烧了
Just don’t burn the house down.
作为复合氧化物 硫氧化物
As antinomy oxides,sulfur oxides form
能产生那种烧焦的火柴味
creating a burning smell.
大家看到的烟 其实是未燃烧的细小颗粒
The smoke you’re seeing is actually tiny unburned particles,
是不完全燃烧产生的
result from an incomplete combustion.
单个颗粒很小无法被看见 但聚集起来就形成烟
Individually they’re too small to see but grouped together they form smoke.
烟里还有部分水蒸气
There’s also some water vapor there.
对了 所有这些过程
By the way, all this stuff that
解释起来花费了90秒
we’re explaining in 90 seconds… it
其实都发生在十分之一秒内
all happens within tenths of a second.
所以说化学反应很快
So chemistry is fast.
