怎样能让火箭绒面耐火

How To Make Fire-Resistant Rocket Wadding (For Pennies)

在这期节目中 我将向你展示如何在家里自制耐火火箭填料
For this project I’m going to show you how to make your own fire resistant rocket wadding at home.
这种特别处理的材料可以防止降落伞在发射过程中融化
This specially treated material prevents your parachutes from melting during the ejection charge,
如果想让火箭完整地回到地面 这项工作必不可少
which is a must-have, if you actually plan on getting your rocket back, in one piece.
然而与其花费一大笔钱购买现成的火箭回收填料
But rather than dropping fistfuls of money on commercial recovery wadding,
不如省下这笔钱 自己来做 而这只需要一小搓家用发酵粉
save your cash and make your own, with a pinch of household baking soda.
在这个项目中 我们将用到一卷卫生纸 一盒纯发酵粉和一点点水
For this project we’re going to need a roll of paper towels, a box of pure baking soda, and a little bit of water.
你家里有可能就有这种发酵粉 观察盒子侧面
Chances are you already have a box somewhere around the house, and if you look on the side,
你会发现所有的发酵粉其实都是碳酸氢钠
you’ll see that all baking soda is, is Sodium Bicarbonate.
当碳酸氢钠被加热时 它会放出二氧化碳气体
When Sodium Bicarbonate is heated up, it releases CO2 gas.
也许你记得二氧化碳可以灭火 而这正是我们想要的
And you may remember that Carbon Dioxide puts out fires, which is exactly what we want.
开始制作阻燃液 首先把一茶匙发酵粉加到四分之一杯水中
Let’s get busy making our fire-retarding solution by adding 1 Teaspoon of baking soda, to 1/4 cup of water.
充分搅拌10到20秒 静置一会儿 直到液体完全静止
Give it a good stir for around 10-20 seconds, then just let it sit for a bit, until everything settles down.
等液体再次澄清时 就成为了饱和溶液
When the water turns clear again it’ll be a super-saturated solution, and you might
可能会在杯子底部有一些白色粉末
see a little white powder at the bottom of the glass.
我们不需要这些粉末 所以需要慢慢的把澄清的液体小心倒到另一只碗里
We don’t need that, so carefully pour the clear liquid into another bowl slowly enough,
这样可以分离出那些没有溶解的粉末
that it leaves the undissolved powder behind.
接下来需要做的是找到一张纸巾 把它浸在碗里大约30秒
Now all you need to do is find a single sheet of paper-towel and toss it into the bowl for about 30 seconds.
然后翻过来检查是不是完全浸湿了
Flip it over and double-check the liquid’s soaked all the way through, and if it has,
如果已浸透 就找一个地方 把纸巾悬挂起来 晾晒几个小时
then find a place where you can hang the wet paper towel for a few hours to drip-dry. Preferably
这期间最好保持室温 或者更暖和
at room temperature, or warmer.
这个量的溶液 足够处理两张纸巾
This amount of solution should be enough to treat two full-size paper towels, and will
大概花费4到24小时完全晾干
take somewhere between 4 – 24 hours to dry out completely.
现在检查一下纸巾 如果是这种双层的
Now check this out. If your paper towel is 2-ply like mine, you can grab one of the corners,
可以抓住纸巾的一个角 把两层分开
and pull the two layers apart.
这样 不需要多花功夫 就可以得到双倍的填料
Just like that, you’ve got twice as much wadding, with hardly any extra effort.
最后一步 将这些纸片叠在一起 把他们切成正方形
To finish up, simply layer the sheets together, and cut them into squares roughly the same
尺寸与厕纸差不多大 就是这么大
size, as a square of toilet paper. And that’s it.
这个过程可制作36块防火可回收填料
You just made 36 squares of fire-resistant recovery wadding, for a few minutes of effort,
而这花费了几分钟的精力和一点点发酵粉
and a pinch of baking soda.
最好的部分就是 可以把填料制作成任意大小 而这只花费几便士
The best part is, you can make your batches as big as you want, and it’ll only cost
这比在特定商店花费的要少得多
you a few pennies. Which is way better than the price you’ll pay at the hobby stores.
仅仅出于好奇 我去买了一些商用填料
Now just for fun, I went ahead and bought some commercial wadding as well, so we could
对比看看它们有什么不同
open the packs up and see how they compare.
这种商用填料看起来像扁平的卫生纸 很有趣的是
Commercial wadding kinds of look like flattened rolls of toilet paper, and funny enough, it’s
上面甚至有方便手撕的小孔
even perforated to tear into little squares as well.
包装上写到 这种材料能保护可回收系统免受热喷射气体破坏
The packaging says this material protects recovery systems from hot ejection gases.
让我们看看用火烧 会发生什么
So let’s see what they do, when we touch them with a flame.
让人惊讶的是 这种纸立马燃烧了 只用了几秒钟就化为灰烬
Surprisingly, the sheet actually catches fire and burns up in just a few seconds.
让我们再看看用苏打自制的填料会怎样呢
Let’s compare that to the make-shift wadding we just made, with baking soda.
不出所料 可以看到纤维被烧焦成黑色
You can see it scorches the fabric and turns it black as expected.
但纸巾并没有着火 火焰很快熄灭
But the tissue doesn’t actually catch fire, and won’t sustain a flame.
与商用材料不同的是 它只是慢慢阴燃 直到填料燃尽
Instead, it just smolders slowly until all the wadding is spent,
或者等二氧化碳掐灭余火
or until the Carbon Dioxide chokes out the embers.
现在不只是家用苏打可以做填料
Now baking soda isn’t the only option for rocket wadding.
事实上 我们身边有很多耐火材料适合做填料
In-fact, all kinds of other fire-resistant materials all around you, perfect for the job.
我从阁楼的隔层里取出一小撮纤维材料
I just pulled a couple handfuls of cellulose insulation out of the attic of my house.
用这个材料做火焰测试 奇怪的它根本无法燃烧
Flame-testing this material, you can see it doesn’t catch fire at all.
只能慢慢阴燃
In surprisingly only in smolder.
阁楼隔层也可以用做耐火填料 这种材料同样便宜且易获取
Attic insulation is another cheap and easily accessible option,
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
and is the same stuff I used for capping the ejection charges of my “Screw-Lock” Sugar Motors
在前一个项目中 我用这个材料填充“螺丝锁-糖”马达的喷射器
and is the same stuff I used for capping the ejection charges of my “Screw-Lock Sugar” motors in a previous project.
详细制作步骤请观看另外一个视频
Look for how to make those from scratch in another project video.
纯粹为了好玩 我从便利店买来四卷纸
Now just for fun, I got a 4 pack of toilet paper rolls from the dollar store,
分别放入四个有苏打水的容器中
and placed each one in a container, filled with the baking soda solution.
苏打水最佳配比为
A good rule of thumb for mixing your solution is
1/4杯水加1茶匙苏打
that for every 1/4 cup of water add 1 teaspoon of baking soda.
把卫生纸浸泡一分钟 它会膨胀开
And if you let your toilet paper roll soak for a minute, it’ll expand enough
这时 不用费劲就可以把纸管取出
that you can reach in and pull out the cardboard tube with hardly any effort at all.
现在 需要充分浸泡 盖上盖子
Now to make sure the paper soaks up the solution evenly, try putting a lid on your container
将容器倒置一分钟
and flipping the whole thing upside down for about a minute.
多余的液体可回收 用于下次使用
Save the excess liquid so you can re-use it with your other rolls, then go ahead
将浸湿的卷纸放在盘子上 风干两周
and lay the sopping wet roll on a plate, where it can air-dry for a couple of weeks.
为了加速风干速度 可以将纸卷放在低温的烤箱中
You could speed the process by putting it in the oven on low heat.
但是这会增加成本
But that’ll increase your energy costs,
并有可能将其转化为碳酸钠 从而降低耐火填料的效果
might convert it into Sodium Carbonate, which will make the wadding a little less effective.
耐心等待4周 纸卷可以完全风干
After about 4 weeks of patiently waiting, you can see my roll has dried out completely.
仔细观察 你会发现外层凝结一层苏打晶体
And if you look closely, you might be able to see how the outer layer has crusted over
这可不是什么好事 看这个
with baking soda crystals, which isn’t really a good thing, but watch this.
如果把外层剥去 就会发现内层柔软而光滑
If we simply peel off the crusty outer layer, we’re instantly left with a soft and smooth interior.
令人印象深刻的是 这款自制材料外观和手感都像极了特殊商品店里的名牌产品
Impressively, this homemade material looks and feels a lot like the name brand stuff
它甚至可以像店里的产品那样方便地撕成小片
from the hobby store, and even tears into smalls sheets the exact same way.
不同的是 我们这种材料更耐火 且不易燃烧
The difference is, our homemade version seems to be a lot more resistant to open flames,
而价格只是商店里的一丢丢
and is only a fraction, of a fraction, of a fraction of the price.
如果你打算用这种自制可回收填料填充“随机化”火箭
Now if you’re planning to use homemade recovery wadding for the “Randomizer” Rocket, made
这种火箭在另外一个视频有介绍 我建议用6张纸来填充一个火箭
in another video, I recommend using 6 sheets of wadding per launch.
首先塞进4张纸进火箭 每次只放一张 放四次
Push the first 4 sheets into the rocket body, one at a time.
然后用两张纸包住降落伞包的底部
Then wrap 2 more sheets around the bottom of the parachute bundle.
再轻轻安放到其它部分的顶部
And nestle it gently on top of the others.
将其它松散的弹力绑绳塞进头锥 然后固定头锥到火箭顶部
Tuck any of the loose elastic cording into the nose-cone, then push it into position on top of the rocket.
可回收系统得到很好的保护 可在发射后回收 准备下次使用
Your recovery system is now protected and ready to spring into action, so it can safely
现在可以发射了
bring your rocket back, for another flight.
顺便说一下 如果想环保
And by the way, if you want to go green and help minimize your impact on the environment,
可以尝试用生菜代替做填料
try using a head of lettuce for parachute wadding instead.
生菜叶子的水分可以起到超级有效的替代作用
The moisture in lettuce leaves make them a surprisingly effective alternative, and the
并且它们可自然分解
best part is, they’re bio-degradable.
现在你了解了如何使用家用苏打来做防火可回收填料
Well now you know how to use ordinary household baking soda, to make a bundle of flame-proof
而自制材料的价格只是商店里的三百分之一
recovery wadding that’s 300 times cheaper to make yourself.
