How Does Silicone React In A Vacuum Chamber


Hello guys! We went back to the lab to conduct a second experiment (silicone) and other molding.
You may remember, in an earlier video tried to pour some of these balls pokemon silicon.
The problem was that it has resulted in our air bubbles are trapped in the rubber, which in turn moved to the successful casting operations.
So in this video, we will try to re-casting of these balls, and see whether we can produce free of bubbles templates.
Thus, in the video append, we made this, it’s hollow compartments designed to pull air from the silicon before they set it up.
In this video will put it to the test, we brought compartment air intake, balls pokemon, and brought more silicon.
Let’s start work in making more rubber molds.
Now, I showed in the previous experience that you can use containers Khjrh biscuits pull air, but for this experiment will be attributed to the use of a pressure cooker.
Because it is wide enough to contain the pot popcorn, which I found in the shop all dollar, the price is about one dollar.
It Eetmoda excellently here, you can see that the lid closes completely and everything is clean.
Because paper he used once, which means easy cleaning process.
Well, the balls pokemon ready and in their positions, and I worked took a different turn this time, let me show you what I did.
First put the Pokemon balls and up vertically and thus air bubbles formed by chance to come out on top of track lines on the ball
Secondly, it took a little mud and made the base at the bottom and this helps in the formation of a reserve stock, even pulls him Mansbh that was candy or wax or aluminum molten during the even cooler filled with balls remain
We hope after these improvements we can make the perfect silicone molds
Now we can mix up a new batch of silicon and use the vacuum to pull air bubbles chamber, and then during the casting set by the sides of the mold away from the ball itself
The higher the level of the liquid is supposed to pay any air bubbles are trapped and giving us the perfect silicone pouring
Now Khaltna silicon Almkhvz together but mix full air bubbles
So now we will pass it to the pot popcorn and put it in a vacuum chamber and pull these air bubbles
In practice we want to fill one-third of my understanding because the bubbles Stjn airway, unfortunately this is more than a third
So we have to be very careful must
To go ahead and get out air bubbles
(The voice of the pump)
I can control my air to enter from here
You can see the negative pressure bubbles extracted from the depths of silicon
To Aaattiyha field to explode
Oowooh, ah
Chaos
Well lesson we learned just, when you put silicone in the vacuum chamber must make it fills only one-third because the bubbles will climb to the top and everything pollution
If there is no room for Vqat to rise and start the explosion will come into contact cover and everything will destroy and restore process
So you should leave enough room for bubbles in order to step up and give them the opportunity to escape
Oooh, this was imminent, was imminent!
This, my friends, is the magic
This is a beautiful somewhat, if I can movement out to different parts of the silicon and access to these bubbles faster
Wow, this sounds amazing
The way that moves really exciting
You can see that it reached the depth of the silicon and that pulls all these bubbles
Whenever we leave it for a longer period the more bubbles out of silicon
Ideally up to a stage where does not contain any bubbles, but I am a little worried because of the time because I want to pour it before it hardens so it will be directed by now
It seems to be ready
We have withdrawn most of the air bubbles
And now I’m excited to see what difference does this
During Sapna silicon it is important to set it up this way beside the ball pokemon
But beyond them Maicon
Anridh the ball itself
You can see that I painted a thin layer of silicon on the balls
For Throwaway minute areas, which may cause problems
Where the bubbles do not hold up there
Slow and Pacific wins race
This may be too much
Slower slower
Heck Oooowo
I make a mess
It looks beautiful
Oh my God, this sounds nice
Molds were filled up to top
Molds were filled up to top
These templates actually look better than I’ve seen before
In fact, if you look at the surface of these templates
They like a lake net
Everything wonderfully reflect
This is a very good means it does not contain air bubbles inside
Now there are some of the lessons learned during the conduct of this experiment
The first lesson that silicon does not meld a single payment
Working with a lot of silicon is very difficult
We are struggling with time because this material hardens within 30 minutes
So if you’re trying to do it yourself Vrko silicon on different batches
And each Okhtaiwha separately
The second lesson when I suggest mixing silicon Taktaiwn hand
Because you do so Tqllon errors
Instead of using this container that you use it
It actually creates many air bubbles
This means that much longer needs in the vacuum chamber
To remove those bubbles again
So if you can you Akhtaiwha your hands
This is what we have today because these templates need 24 hours to harden completely
So we will let it harden at night and take a look at the results tomorrow
Thank you for joining me in this project, Ontzerkm in another video, talk to you later ….
Oh my God made a mess
You will be forced to clean up this later
Thank you for watching and remember that I was given Jawaiza now in every new video
