World Webbing formula

White Widow you've done it again, you filled in all of the gaps in my formula with your website, thanks.

 

[White_widow]

No problem! I hope to experiment with this formula in my plastic/adhesive class. Do you have any ideas for modifications? There might be some problems for us when it comes to even distribution.

 

[White_widow]

So guys, I just looked at an article with the tensile strength of Graphene modified PVA. With only a .5 % weight addition of graphene, the tensile strength increased 212%. The tensile strength of steel is twice of the modification. I'm hoping that with the addition of 5% or so would actually increase it to past that of steel. Again, I'm still hypothesizing it, but there are variables that I don't know how to predict with my limited chemistry knowledge.

 

[spidey44]

for even distribution a section before the nozzle could be a funnel shape, to create a vortex, which would hopefully mix the contents.

 

[White_widow]

I'm liking that. Honestly never thought of that one before. ^^

 

[White_widow]

Wow, there is so much info I neglected first time around on this project. So I was looking at some old information, and the term plasticizer came up for both nylon and PVA. I was curious. I just checked that out. A plasticizer is a material that allows a solid plastic to become more workable. It still allows it to stay solid, but it becomes more like a paste. When the platicizer evaporates, the material becomes more rigid. It's very fascinating. Water acts like a plasticizer and a solvent to PVA and. Perhaps we shouldn't be searching for solvents as we should these chemical compounds.

So how this applies to our project is taking into consideration the shear thinning properties. While our current fluid doesn't have them, parkers did. If he had a plasticizer, the solid would remain sheer thinning until it left the cartridge and the plasticizer evaporated. Actually, that would help explain why the fluid would retain it's shape and eventually turn into powder. Eventually, the thing would just get too brittle.

I Knew that they made the material weaker but i didn't know that they turned it into a paste, Nail polish remover does something similar to that on gorilla glue, it forms little particles of the glue but when the nail polish remover evaporates it leaves a thin layr of dried glue on the bottom.

 

[White_widow]

I'm guessing it's in how much you use and the material you're using. A solvent will only soften a material if there's not enough.

 

[spidey44]

I'll keep that in mind the next time I experiment with it, it was hard trying to make it mix with the soap so it would foam up.

 

[White_widow]

That's true. Foaming is a three part process. You need lots of propellant, a spaghetti drainer-type mesh, and the surfactant. the thing is, the way soap works is by attatchment to non polar substances and water. with polyurethane, the substance doesn't act as a polar or non-polar. It absorbs water and I think the soap interferes.

 

[spidey44]

I might have to switch to super glue I guess.

 

[White_widow]

Super glue also reacts with water and it doesn't expand naturally. Expansion isn't neccessary for the protoype. Expansion is what we work on after we create a material that is strong enough after being fired. It is then that we work on getting the most out of our fluid.

 

[spidey44]

I don't think I will need water now that I think about it because silly string foams but doesn't have water in it.

 

[White_widow]

Alright. That's what causes expansion in polyurthane though.

 

[Symbiote-Man]

I feel like an old man, I can't remember. But.. The formula I use, (flubber, with a few mods) can't even support it's own weight when it's a long strand. Sooooooooooo... at the risk of sounding like a broken record, White Widow, got any ideas for a strengthener?

 

[White_widow]

Polymers tend to take the properties of the bases. The difference belongs in the crosslinking agents and the physical structure if there is a chemical change. Your bases are glue and powder. When dry both are brittle and the glue is always weak. If you're going to do that, I would try it with a different base.

 

[Symbiote-Man]

Ok, thanks!

 

[spidey44]

would fiber filaments help is form strands that can hold their own weight, and make it stronger.

 

[Symbiote-Man]

Maybe, but I can't do that because of my shooter.

 

[White_widow]

Fiber filaments do help. In certain glues, the fibers can mean the difference between a good bond, and a permanent bond. The strongest glue contains rubber particles and glass fibers.

 

[Symbiote-Man]

Now although I like the flubber, I have thought of a plan that will allow a way of making a PROP that will allow me to wear it under my costume. Is has to do with my original idea, but now I know more than last time I tried to do it. The strand is small, and all it could pull over would be a paper cup, but it's SMALL, and it could work.

 

[Symbiote-Man]

Original idea meaning hot glue.

 

[White_widow]

Really? What's the idea? I'd love to hear about it. ^^

 

[Symbiote-Man]

Actually, I tested expiremented and tested more, and I disguarded that idea. But I thought about a fishing wire and spike projectile.

 

[White_widow]

This is a prop right?
