硅胶在真空室里会发生什么反应？ | TKOR的真空室硅胶实验：英语精读讲义

Hey guys, we are back in the lab again for another silicone casting experiment.

大家好，我们又回到实验室进行另一次硅胶倒模实验了。

You might remember in a previous video,

大家可能还记得在之前的视频里，

I tried casting some of these Poké Balls with silicone,

我尝试用硅胶倒模制作了一些精灵球，

and the problem we ended up having was bubbles that got trapped in the rubber, 短語動詞

结果遇到的问题是气泡被困在了橡胶里，

which transferred to all the successive castings.

这导致后续的所有倒模都出现了这个问题。

So, in this video,

所以，在这期视频中，

we're going to try recasting these Poké Balls and seeing if we can get rubber molds that are completely bubble free. 用詞

我们打算尝试重新给这些精灵球倒模，看看能不能做出完全没有气泡的橡胶模具。

So, in a follow-up video,

于是，在后续的视频里，

we made this thing.

我们制作了这个东西。

This is a vacuum chamber that's designed to suck the air out of the silicone before we pour it. 講解

这是一个真空舱，专门用来在倒入硅胶前将其内部的空气抽出来。

So, in this video,

那么，在这期视频中，

we're going to put it all to the test. 習語

我们要对它进行全面测试。

We've got our vacuum chamber, we've got our Poké Balls and we've got some more silicone.

我们有真空舱，有精灵球，还准备了更多的硅胶。

So, let's get busy making some more rubber molds. 短語搭配

那么，让我们开始制作更多的橡胶模具吧。

Now, I showed you in a previous experiment that you could use glass cookie jars as your vacuum chamber,

在之前的实验里我给你们展示过，可以用玻璃饼干罐当作真空舱，

but for this experiment,

但在这个实验里，

I'm going back to my pressure pot because it's wide enough to accept this popcorn dish that I found at the dollar store. 語法

我打算重新使用我的压力罐，因为它足够宽，能装下我在一元店找到的这个爆米花碗。

This is only about a buck and it fits perfectly inside the container here, 用詞

这只要一美元左右，而且完美地贴合在这个容器里面，

and you can see the lid fits on and everything's flush. 用詞

你可以看到盖子也能盖上，所有东西都很平整。

And because it's paper,

而且因为它是纸做的，

it's disposable,

是一次性的，

which means very easy cleanup.

意味着清理起来非常容易。

All right, update.

好了，更新一下进度。

Hey guys, we got our Poké Balls set and positioned,

伙计们，我们的精灵球已经放置并定位好了，

and I took a little bit of a different approach this time. 短語搭配

这次我采取了稍微不同的方法。

Let me show you what I did.

让我给你们看看我是怎么做的。

First of all, I took the Poké Balls and set them upright so the button is facing toward the ceiling. 短語搭配

首先，我把精灵球直立放置，让按钮朝向天花板。

This way, if there are any accidental air bubbles trapped inside,

这样，如果里面意外困住了气泡，

they should be able to follow the lines and escape.

它们就能顺着纹路跑出来。

Second of all, I took some clay and made a big base around the bottoms,

其次，我用了一些黏土在底部做了一个大底座，

and this is to help form a reservoir, 用詞

这是为了帮助形成一个储液区，

so when we're pouring molten gummy wax or molten aluminum,

这样当我们倒入熔化的凝胶蜡或熔铝时，

it'll have a reservoir to draw from as it cools and keep the Poké Balls full. 短語動詞

在冷却时就会有备用液体进行补充，以保持精灵球是充满的状态。

Hopefully, with those improvements,

希望通过这些改进，

we can make ourselves some perfect silicone molds.

我们可以做出完美的硅胶模具。

So, now we can mix up a new batch of silicone and use our vacuum chamber to suck the air bubbles out,

所以，现在我们可以混合新的一批硅胶，并用真空舱抽出气泡，

and then as we pour it,

然后在倒的时候，

we want to pour it in a long thin stream far away from the Poké Ball itself.

我们要让它形成细长水流状，倒在离精灵球本身较远的地方。

As the liquid level rises,

随着液面上升，

it should push any trapped air out and give us a perfect silicone casting.

它可以把任何困住的空气挤出来，从而得到一个完美的硅胶倒模。

Oh, it's so satisfying.

噢，太解压了。

We've got our silicone and our catalyst blended, 用詞

我们已经把硅胶和催化剂混合好了，

but it's full of air bubbles.

但里面全是气泡。

So, now we're going to transfer it to this popcorn container,

所以，现在我们要把它转移到这个爆米花容器里，

stick it inside our vacuum chamber and suck those air bubbles out.

把它放进我们的真空舱，抽出那些气泡。

Now, we actually only want to fill this up about a third of the way from what I understand, 語氣意圖

据我所知，实际上我们只应该倒大约三分之一的量，

because the air bubbles are going to go crazy,

因为气泡会疯狂膨胀，

and unfortunately,

而不幸的是，

that's more than a third of the way.

现在的量已经超过了三分之一。

So, we're going to have to be very careful.

所以，我们必须非常小心。

Let's go ahead and extract these bubbles. 語氣意圖

我们这就开始抽取这些气泡吧。

Now, I can actually regulate the airflow here.

现在，我其实可以在这里调节气流。

You can see it's digging deep down in the silicone now and pulling out all those bubbles.

你可以看到它现在正在深入硅胶内部，把所有气泡都抽出来。

It's not giving them a chance to pop. 短語搭配

根本不给它们破裂的机会。

Whoops.

哎哟。

Oh,

噢，

shoot.

糟了。

Made a mess.

弄得一团糟。

Okay, so lesson that we just learned,

好了，我们刚吸取了一个教训，

when you're putting silicone in the vacuum chamber,

当你把硅胶放进真空舱时，

you only want to use about 1/3 of the liquid because the bubbles will rise up and contaminate everything.

你只能装大约1/3的液体，因为气泡会升上来并污染周围的一切。

If there's not enough space for the bubbles to come up and start popping, 語法

如果没有足够的空间让气泡升上来并开始破裂，

they're going to hit the lid,

它们就会碰到盖子，

and every time you deflate it, it's just going to repeat the process. 語法

而且每次你放气时，只会重复这个过程。

So, you need to leave enough of a gap so the bubbles come up and have a chance to escape. 短語搭配

所以，你需要留下足够的空隙，让气泡能升上来并有机会排出去。

Ooh, that was close.

噢，好险。

That was close.

真的好险。

And that right there, my friends, is the magic. 表達脈絡

朋友们，这就是见证奇迹的时刻。

Well, that's kind of cool.

哇，这还挺酷的。

If I move it around,

如果我到处移动它，

I can actually like access different parts of the silicone and get that bubbling faster.

我居然能触及硅胶的不同部位，让它冒泡得更快。

Oh, wow.

噢，哇。

That looks amazing.

看起来太神奇了。

It's very cool the way that that churns.

它翻腾的样子非常酷。

You can see it's digging deep down in the silicone now and pulling out all those bubbles.

你可以看到它现在正在深入硅胶内部，把所有气泡都抽出来。

The longer we let this sit, 語法

我们放得越久，

the more air is going to come out,

就会有越多的空气排出来，

and ideally, it would get to the point where there are no more bubbles whatsoever. 講解

理想情况下，它会达到完全没有气泡的状态。

But I'm a little bit nervous on timing because I want to get this silicone poured before it actually sets up.

但我对时间有点紧张，因为我想赶在硅胶凝固前把它倒出来。

So, we might just take it out now and pour it.

所以，我们可能现在就得拿出来倒了。

There we go.

好了。

It looks like it's ready.

看起来准备好了。

We've sucked out quite a few of the air bubbles here now. 短語搭配

我们现在已经抽出了很多气泡。

I'm excited to see what difference this makes. 語法

我很期待看到这会带来什么不同。

Now, as we pour this,

现在，当我们倒进去时，

the key is to pour a long thin strand next to the Poké Ball, 語法

关键是在精灵球旁边倒出细长的一条，

but as far away from it as we can get. 語法

且要尽量离它远一点。

We don't actually want it going on the Poké Ball itself.

我们其实不想让它直接浇在精灵球上。

And you can see that I've painted a thin layer of silicone into some of the problem areas so that as the bubbles rise, 語法

你们可以看到，我已经在一些容易出问题的区域涂了一层薄薄的硅胶，这样气泡升起时，

they don't get trapped up there.

它们就不会被困在上面。

Slow and steady wins the race. 習語

稳扎稳打才能赢。

That might even be too much.

那可能有点太多了。

Slow down, Grant.

慢点，Grant。

Oh, dang.

噢，糟了。

I'm messy.

我弄得好乱。

That's looking beautiful.

看起来真漂亮。

Oh, my gosh.

噢，我的天哪。

That is looking beautiful.

看起来非常漂亮。

So, cool, guys.

太酷了，伙计们。

Our molds are filled up to the top,

我们的模具已经填满了，

and these are actually looking better than I've ever seen before. 語法

而且这看起来比我见过的任何一次都要好。

In fact, if you look at the surface of these molds, 表達脈絡

事实上，如果你看看这些模具的表面，

it almost looks like a crystal clear lake reflecting everything perfectly, 習語

它几乎就像一个清澈见底的湖泊完美地倒映着一切，

which is a really good sign.

这是一个非常好的兆头。

It means we probably don't have any bubbles in there.

意味着里面可能没有任何气泡。

Now, there are a couple lessons I learned while doing this experiment today.

今天做这个实验我学到了几个教训。

Number one,

第一，

I wouldn't have mixed up the whole batch of silicone at once. 語法

我不应该一次性混合整批硅胶。

Working with so much silicone is very difficult,

处理这么多硅胶非常困难，

and we're fighting the clock because this stuff sets up in about 30 minutes. 講解

我们是在和时间赛跑，因为这东西大约30分钟就会凝固。

So, if you try this yourself,

所以，如果你自己尝试，

divide your silicone into different batches and mix one at a time. 短語搭配

把硅胶分成几批，一次混合一批。

Number two,

第二，

when you're mixing this,

混合的时候，

it's been suggested to mix it by hand because you'll introduce less air by doing that. 語法

建议用手搅拌，因为这样引入的空气会更少。

By using something like these mixing beaters that I was using,

像我一样使用这种搅拌器，

it's actually pumping a ton of air into there, 用詞

实际上往里面打了大量的空气，

which means it takes a lot longer in the vacuum chamber to extract all those bubbles back out. 語法

这意味着在真空舱里抽出所有这些气泡需要花更多的时间。

So, if you have the option,

所以，如果有选择的话，

don't use a mixing beater.

不要使用搅拌器。

Mix your silicone by hand.

用手搅拌硅胶。

So, that's it for today because these things are going to need about 24 hours to cure. 講解

今天就到这里了，因为这些东西需要大约24小时来固化。

So, we're going to let them sit overnight,

所以，我们要让它们静置过夜，

and we'll take a look at the final result tomorrow.

明天再看看最终结果。

Thanks for joining me for this project.

感谢大家陪我完成这个项目。

I'll be looking for you in the next video.

到时聊。

Shoot.

糟了。

Made a mess.

弄得一团糟。

Have to cleanup later.

晚点得打扫了。
