World Web shooter shop class - Part 4

Liquidated?

 

[White_widow13]

Yeah, my email address was for a domain belonging to my dad. Because it was a custom domain, and because he liquidated the domain, everything attached was removed including my email.

 

[Seafood]

Aight. Sounds legit.

 

[BUTTONSPAM4DAYZ]

It would be cool to make a small wrist paintball gun and it would shoot paint balls with web fluid in them.

It would be like this.

 

[BUTTONSPAM4DAYZ]

Ok I got some ideas... Lol just trying to start conversation :P

 

[White_widow13]

I feel the same way. Conversation has halted. What are some of your ideas?

 

[BUTTONSPAM4DAYZ]

PVOH has its pros and cons here are the cons

-Not soluble in acetone. Because we are using water to dissolve it it would not solidify fast enough
-I want to use cyanoacrylate but you said PVOH IS THE ONLY FLUID.
-I also want to use PVP for the elastomer and tackifier but you said the chemical bond would be loose.

Pros
-Very strong
-Water soluble
-Non-toxic,ETC.

 

[White_widow13]

Ok, I suppose that I should explain myself on these points.

-It is correct that it is unlikely that a quick runthrough of a fluid through a heated spinneret would create the evaporation neccessary to solidify the fluid quickly. I am currently investigating 3 methods of evaporating the solvent faster.
A.) Ice evaporation:http://www.youtube.com/watch?v=L2Nu9bZveyE (a strange phenomenon where a boiling liquid vaporizes the second it hits frigid air.

B.) Lengthening the spinneret by coiling it into a bracelet so that it can move through 2 FEET of spinneret vs 3 INCHES. That way it would have much more time to heat up. Though hopefully not too much time.

C.) adding some highly soluble, flammable solution to the water that dissolves the PVOH to drastically reduce boiling point.

- PVOH IS THE ONLY FLUID. That is only partially correct out of context. In proper context, you'll notice that it is the only fluid that matches the properties of webbing in tensile strength, appearance, method of spinning, flexibility, and other such properties. Of course we will need other additives. Cyanoacrylate is the ONLY adhesive that will bond quickly and strongly enough (unless we can turn PVOH into a "pressure sensitive adhesive"http://en.wikipedia.org/wiki/Pressure-sensitive_adhesive)

So that being said, the only three fluids in the "formula" would be PVOH, water, and perhaps something to lower water's boiling point. Cyanoacrylate would actually come later, but I'll explain that in a later post.

-PVP may or may not work. It may. I haven't researched its properties. PVOH is actually an elastomeric compound when it contains excess water (but not enough water to dissolve it.)

I hope that makes sense. Please ask a question if it didn't.


When it comes to web fluid, I just want everyone to see that we need to start with the simple things and work up. Polyvinyl alcohol is the only fluid that we could make at home for cheap consistantly. It's also going to yield better results than styrofoam, which is a failed idea that I came up with in the beginning. IN SHORT, I'M TRYING TO GET RID OF SOME OLD MISTAKES THAT I MADE WHEN I FIRST STARTED. BY FOCUSING ON PROVEN AND TRIED METHODS RATHER THAN UNSUPPORTED THEORY.

 

[White_widow13]

I'm tired of doing everything through flikr. I'm making a bare bones blog so that you all can see my research.

[BUTTONSPAM4DAYZ]

WW I am afraid there is a bug on your website. When reading it just goes white and I will have to highlight the words so I can see them.

 

[BUTTONSPAM4DAYZ]

And yeah styro foam will not work. I did an experiment with it and it does not mix with glues.

 

[Wadaltmon]

I'm focusing on a spirit gum basis right now.

 

[BUTTONSPAM4DAYZ]

Hi wadaltmon, may I ask what your formula is? Please

 

[White_widow13]

man, everything has completely stopped. What is the hardest part of this project?

1.) The fluid
2.) shooting the fluid
3.)evaporating/spinning the fluid

For me individually, my biggest issue is trying to combine all of those pieces. Currently, I have the fluid and the shooter, and the spinneret, but giving the fluid enough time to evaporate is an issue.

How about for you all?

 

[pllagunos]

What about using the current ideas? A longer and hotter spinneret insulated by silicone tubing, a propeller connected to a motor and mixing water and ethanol for the solvent so it literally burns (and evaporates) more quick.

 

[BUTTONSPAM4DAYZ]

I really don't like the burning ethanol idea. Like dude, ethanol is used in fire places so I don't think the flame will be "Cool'', also ethanol fires are harder to put out than gasoline fires.

 

[White_widow13]

true, but it's combination with water, and it's low amount, it would burn out immediately and be smothered by the polymer. Out of curiosity, how do you propose us vaporize the solvent in the solution?

 

[BUTTONSPAM4DAYZ]

Sorry if I sounded like a real butthole but I think I will posiibly go with melt spinning.

 

[BUTTONSPAM4DAYZ]

If enough pressure behind the fluid won't it "self-stick"? Like a spitball, it has no adhesive but once it hits a wall it adheres.

 

[BUTTONSPAM4DAYZ]

? What are some good surfactants?

 

[Shade Widow]

What if we make a miniature motor similar to the ones in electric weed eaters and have tubes in it so when the fluid is extruded from the pressurized cartridge via solenoid valve it will be spun into a strand like in the movies and when the solenoid on the end opens there will be a custom designed valve with a small point in the center to make it shoot in a cone. The chamber with the spinneret in it will be wrapped in copper wire as a heating mechanism.

 

[BUTTONSPAM4DAYZ]

won't the tubing that the web is coming from get tangled up

 

[BUTTONSPAM4DAYZ]

And welcome, shade widow

 

[Shade Widow]

We could coat it in teflon
