矽膠在真空室裡會發生什麼反應？ | TKOR的真空室矽膠實驗：英語精讀講義

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

大家好，我們又回到實驗室進行另一次矽膠倒模實驗了。

You might remember in a previous video,

大家可能還記得在之前的影片裡，

I tried casting some of these Poké Balls with silicone,

我嘗試用矽膠倒模製作了一些寶貝球，

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

結果遇到的問題是氣泡被困在了橡膠裡，

which transferred to all the successive castings.

這導致後續的所有倒模都出現了這個問題。

So, in this video,

所以，在這期影片中，

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

我們打算嘗試重新給這些寶貝球倒模，看看能不能做出完全沒有氣泡的橡膠模具。

So, in a follow-up video,

於是，在後續的影片裡，

we made this thing.

我們製作了這個東西。

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

這是一個真空艙，專門用來在倒入矽膠前將其內部的空氣抽出來。

So, in this video,

那麼，在這期影片中，

we're going to put it all to the test. 慣用語

我們要對它進行全面測試。

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

我們有真空艙，有寶貝球，還準備了更多的矽膠。

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

那麼，讓我們開始製作更多的橡膠模具吧。

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

在之前的實驗裡我給你們展示過，可以用玻璃餅乾罐當作真空艙，

but for this experiment,

但在這個實驗裡，

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. 文法

我打算重新使用我的壓力鍋，因為它足夠寬，能裝下我在一元店找到的這個爆米花碗。

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

這只要一美元左右，而且完美地貼合在這個容器裡面，

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

你可以看到蓋子也能蓋上，所有東西都很平整。

And because it's paper,

而且因為它是紙做的，

it's disposable,

是一次性的，

which means very easy cleanup.

意味著清理起來非常容易。

All right, update.

好了，更新一下進度。

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

夥伴們，我們的寶貝球已經放置並定位好了，

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

這次我採取了稍微不同的方法。

Let me show you what I did.

讓我給你們看看我是怎麼做的。

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

首先，我把寶貝球直立放置，讓按鈕朝向天花板。

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

這樣，如果裡面意外困住了氣泡，

they should be able to follow the lines and escape.

它們就能順著紋路跑出來。

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個大底座，

and this is to help form a reservoir, 用詞

這是為了幫助形成一個儲液區，

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

這樣當我們倒入熔化的凝膠蠟或熔鋁時，

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

在冷卻時就會有備用液體進行補充，以保持寶貝球是充滿的狀態。

Hopefully, with those improvements,

希望透過這些改進，

we can make ourselves some perfect silicone molds.

我們可以做出完美的矽膠模具。

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

所以，現在我們可以混合新的一批矽膠，並用真空艙抽出氣泡，

and then as we pour it,

然後在倒的時候，

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

我們要讓它形成細長水流狀，倒在離寶貝球本身較遠的地方。

As the liquid level rises,

隨著液面上升，

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

它可以把任何困住的空氣擠出來，從而得到一個完美的矽膠倒模。

Oh, it's so satisfying.

噢，太療癒了。

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

我們已經把矽膠和催化劑混合好了，

but it's full of air bubbles.

但裡面全是氣泡。

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

所以，現在我們要把它轉移到這個爆米花容器裡，

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

把它放進我們的真空艙，抽出那些氣泡。

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

據我所知，實際上我們只應該倒大約三分之一的量，

because the air bubbles are going to go crazy,

因為氣泡會瘋狂膨脹，

and unfortunately,

而不幸的是，

that's more than a third of the way.

現在的量已經超過了三分之一。

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

所以，我們必須非常小心。

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

我們這就開始抽取這些氣泡吧。

Now, I can actually regulate the airflow here.

現在，我其實可以在這裡調節氣流。

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

你可以看到它現在正在深入矽膠內部，把所有氣泡都抽出來。

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

根本不給它們破裂的機會。

Whoops.

哎喲。

Oh,

噢，

shoot.

糟了。

Made a mess.

弄得一團糟。

Okay, so lesson that we just learned,

好了，我們剛吸取了一個教訓，

when you're putting silicone in the vacuum chamber,

當你把矽膠放進真空艙時，

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

你只能裝大約1/3的液體，因為氣泡會升上來並污染周圍的一切。

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

如果沒有足夠的空間讓氣泡升上來並開始破裂，

they're going to hit the lid,

它們就會碰到蓋子，

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

而且每次你放氣時，只會重複這個過程。

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

所以，你需要留下足夠的空隙，讓氣泡能升上來並有機會排出去。

Ooh, that was close.

噢，好險。

That was close.

真的好險。

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

朋友們，這就是見證奇蹟的時刻。

Well, that's kind of cool.

哇，這還挺酷的。

If I move it around,

如果我到處移動它，

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

我居然能觸及矽膠的不同部位，讓它冒泡得更快。

Oh, wow.

噢，哇。

That looks amazing.

看起來太神奇了。

It's very cool the way that that churns.

它翻騰的樣子非常酷。

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

你可以看到它現在正在深入矽膠內部，把所有氣泡都抽出來。

The longer we let this sit, 文法

我們放得越久，

the more air is going to come out,

就會有越多的空氣排出來，

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

理想情況下，它會達到完全沒有氣泡的狀態。

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

但我對時間有點緊張，因為我想趕在矽膠凝固前把它倒出來。

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

所以，我們可能現在就得拿出來倒了。

There we go.

好了。

It looks like it's ready.

看起來準備好了。

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

我們現在已經抽出了很多氣泡。

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

我很期待看到這會帶來什麼不同。

Now, as we pour this,

現在，當我們倒進去時，

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

關鍵是在寶貝球旁邊倒出細長的一條，

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

且要盡量離它遠一點。

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

我們其實不想讓它直接澆在寶貝球上。

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, 文法

你們可以看到，我已經在一些容易出問題的區域塗了一層薄薄的矽膠，這樣氣泡升起時，

they don't get trapped up there.

它們就不會被困在上面。

Slow and steady wins the race. 慣用語

穩紮穩打才能贏。

That might even be too much.

那可能有點太多了。

Slow down, Grant.

慢點，Grant。

Oh, dang.

噢，糟了。

I'm messy.

我弄得好亂。

That's looking beautiful.

看起來真漂亮。

Oh, my gosh.

噢，我的天哪。

That is looking beautiful.

看起來非常漂亮。

So, cool, guys.

太酷了，夥伴們。

Our molds are filled up to the top,

我們的模具已經填滿了，

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

而且這看起來比我見過的任何一次都要好。

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

事實上，如果你看看這些模具的表面，

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

它幾乎就像一個清澈見底的湖泊完美地倒映著一切，

which is a really good sign.

這是一個非常好的兆頭。

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

意味著裡面可能沒有任何氣泡。

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

今天做這個實驗我學到了幾個教訓。

Number one,

第一，

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

我不應該一次性混合整批矽膠。

Working with so much silicone is very difficult,

處理這麼多矽膠非常困難，

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

我們是在和時間賽跑，因為這東西大約30分鐘就會凝固。

So, if you try this yourself,

所以，如果你自己嘗試，

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

把矽膠分成幾批，一次混合一批。

Number two,

第二，

when you're mixing this,

混合的時候，

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

建議用手攪拌，因為這樣引入的空氣會更少。

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

像我一樣使用這種攪拌器，

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

實際上往裡面打了大量的空氣，

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

這意味著在真空艙裡抽出所有這些氣泡需要花更多的時間。

So, if you have the option,

所以，如果有選擇的話，

don't use a mixing beater.

不要使用攪拌器。

Mix your silicone by hand.

用手攪拌矽膠。

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

今天就到這裡了，因為這些東西需要大約24小時來固化。

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

所以，我們要讓它們靜置過夜，

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

明天再看看最終結果。

晚點得打掃了。
