I am going to make a video with all types of "rocks" that are reinforced with some glue! Please let me know what material do you want to see turned into hydraulic-press-super-composite! I myself want to see at least socks! :D
Thin fabric like nylon tights could be interesting. I'm concerned that you're getting close to an actually practical application with these composite test pucks!
Ok I must not have read the title thoroughly because I saw this comment and the first reply and were like okay but that’s kinda a stretch that we r all thinking this. (After reading this comment I was like lol that makes sense)
Try shredded paper. Less work to load into the die with random orientation between the pieces. Also have you ever thought of trying to make sintered stone? Edit: It'd also be cool to see how those compressed paper disks pyrolyze, how dense the resulting charcoal ends up being, etc.
He's been doing this without a binder for years - always the same result of crumbly powder like pieces. No where near enough pressure to fuse this stuff together on its own. It's getting really boring.
I'm a printer by trade, & I use synthetic "paper" quite often to make brochures, menus, business cards...etc. Synthetic paper is *VERY* tough material to break or manipulate like regular offset paper is. So...the challenge is this: Make some pucks out of synthetic paper (glue optional) & then make them explode in the end. They *SHOULD* (hopefully) make quite a paper explosion! /By the way, synthetic CAN be quite pricey, so be aware of that.
This is a good idea. different types of paper, Bond paper, recycled paper, money paper, etc. maybe the synthetic paper company can sponsor the video. btw, did dunder miflin sell synthetic paper too
I used to be a guillotine operator and the squeak of gloss paper getting cut made me think that compressing gloss paper will make the hydraulic press explode! It's a risk, but I want to see it! 🤘😂
@@reggiep75 60 or 70# gloss text will ABSOLUTELY explode under that much pressure. The "stick-tion" between the sheets will hold it together until the very end & then ka- *BLAM!!* lil pieces of paper everywhere! /But yeah...I know that zzZZZ*ZZZzz* sound you're talking about when a fresh knife gets used!
@@ScottMeister - Right, that's signed it!! It's gloss paper (various weights) vs the Hydraulic press 😂, but I doubt the press will survive the first attempt of crushing anything gloss/gloss coated. I seriously hope he does try it tho and covers all the windows in the factory with steel plating. It's gonna be one help of an explosion
You can try sawdust, wood chips, wood shavings, etc. It would be interesting to see the difference in strengths from the various sized starting materials. Particle board vs OSB type of thing.
How expensive/dangerous is to keep the max pressure on the machine once it's there? I think a lot of these would result differently if they were allowed to set at high pressure for some time instead of just being pressured for a few seconds. Just like cutting a recently baked cake will result in it crumbling or melting, but it keeps its shape after setting in the fridge.
A typical hydraulic press is not designed to maintain the pressure for extended periods, and you will generally damage your equipment. In general, you need to press a locking mechanism into place that will maintain a fixed position(even though the pressure will not be constant), because otherwise your hydraulic pump will overheat and/or your lines will burst from the strain.
You missed a great chance to try how the Rock-Paper(c) burns! Also if you could try two different sets of paper, the other you leave under pressure for longer time, like an hour. This would allow it to compress even more and reduce the chance for the fibers to just deform and spring back when you release it. Would be fun to see if there is any difference between them.
I'd love to see a sandwich of alternating paper and aluminum foil. You already showed what happens if you fold paper more than 7 times, and in an early video you also showed that aluminum foil could be folded again and again just like kneading bread dough... but what happens if you mix them?
You need to crumple up the post it notes. Crushing them when all the papers are aligned like that gives them a slip surface, which is why it didn't take much to crush it after you pulled it out
As others have commented, it would be interesting to see how it would be to set on fire, and how it burns if it actually burns. But interesting stuff! :)
Paper is coated with a powered rock to absorb ink, and that's likely why the A4 paper comes out like rock. It would be interesting to try newspaper (non-slick) or paper towels Better yet... shop cloths
Maybe you should press cereals into cereal bars. The press other things into "breakfast bars" like popcorn, oatmeal, crispy bacon, etc. Love the channel!
I believe they explored this concept earlier. However: Pressing coffee grounds into coffee cakes to make an entire 12 litres of coffee at once would be cool.
I love how this channel gets straight to the point when the title says "I'm going to do this, and let's take a look at other variations after that" Instead of other channels saying "I'm going to do this, but I won't show it to you right away because I want money and I won't tell you when I did what I said I would do so that you could just skip to it"
First, I would love to see the stickynotes placed in horizontally rather than vertically to make an exploding puck. Also, you should make a glue puck out of matches and then catch it on fire and see if it performs like a composite log haha!
I love your ideas for content! I would like to suggest heating the pressure cylinder to around 300°f, well below the flash point of paper so to help the glue to set more quickly. I also wonder if holding the pressure, for some time, would make much difference. We're glad to know you're feeling better. Thanks for the entertainment!
I would like to see about 10 different colors of paper used. Cut some in circles and layer them. For example, 20 circles of red then on top of that 20 circles of yellow, then 20 circles of blue until you stack all 10 colors in the cylinder. Then compress them. Also for another test shred the colors and keep them separate. Load the different colors on top of each other and then compress. Lastly shred ALL the colors together and load the cylinder until it's full...compress. That could bring you some unusual patterns. Good video.
I think, judging by that reaction (or lack thereof) to the explosion, we can definitely tell by now he has done this a lot. Lauri must be an expert of paper explosions by now! And yet it never gets old.
Could try pressing some layers of carbon felt and wire wool together? See if the result is hard enough to make a tool knife or something out of, if it doesn't just fall apart!
Things to turn into hockey pucks with glue: - Cotton face pads / balls / Q-tips - Bone dust / bone meal - Bentonite clay powder - Diatomaceous earth powder - Fine/powder like saw or wood dust You should try loosely mix the ingredients with the glue before you put it into the press.
I hope you are feeling better. You could have skipped this week. We all would've understood! But, just like you always are, a hard worker, you still got it done. Great job. A thought I had: It would have been neat to see what happens if you put the rocks of paper into water. 😀
You mentioned carbon in the video. Mix the glue with food-grade (wood source) charcoal. It's the most carbony wood product around. Then smash and dry. Is it harder than paper rock?
Try with some epoxy glue. No need to wait days to let it dry. Be sure to cover all internal surfaces with some grease so that the epoxy don't weld with the tools.
When making Masonite you "explode" wood using a high pressure chamber and super heated steam. This effectively heats the lignin in the wood which makes it soft and pliable and then separates the fibers without breaking them. The pulp is then pressed into the shape intended and as it cools the lignin harden and you end up with Masonite. So there is actually no added binding material in it and it's much denser than regular wood. It would be interesting to see if you could achieve something similar using wood and the hydraulic press. Would it be enough to just rely on the heat build up that the pressure causes or would it help to preheat the the cylinder? Actually separating the fibers using superheated steam is probably not easy to achieve without pretty expensive equipment, but "cooking" the wood might be worth a try. It would also be interesting to see what the density of a pressed wood "puck" would be compared to Masonite...
I agree, it's better to have to much sheeet paper than not enough sheeet paper. I had to laugh when the first paper exploded at the 3:40 mark and you made the spitting sound with your lips.
Idk. I mean it is fall. So maybe try turning some leaves into rock with the press. That or some pumpkin. Something auttumn themed would probably make for a good festive video.
I'm not sure what the bolt is for on your machine. But it blows my mind that the bolt can withstand the pressures exerted. And you have a great channel!
Cut fabric squares, add resin, press it and let it dry. This is called micarta and it's incredibly strong. You could make a skateboard out of old t-shirts.
dry leaves, plastic shavings, metal shavings, leather strips, old jeans, socks, textiles, brick pieces, cardboard, treebark, neoprene, vacuumcleaners bag and/or it's insides, potato peels, plants just straght from the ground; like grass, rubber pieces; car tires or something, matches, old work gloves you have laying around, näkkileipää, neulasia and teddybear stuffing. Try any of those with some glue!
You could make a paper,glue,water mixture with the toilet paper with a texture of porrigde and press that together as itself left to dry already forms a quiet interesting papmache thats also quiet solid so pressing that together could realy bond the fibers together . Also a burn test would be interesting. Like does it burn self sustained? How easy is it to light up? (Compared to for example paper,wood and coal) If it burns for how long?
You should just use a lot less glue, I think. Also for other ideas how about adding a small amount of epoxy? that gets -really- hard and would make a great rock :)
That right there is a great idea for recycling used paper, compact paper into such kind of sheets with a biodegradable binder and then you have a hard material that can be used for a number of applications...
I wonder if you can use that to combine fiberglass (either in wool form or in mat form) with polymer. If you do that, however, clearances will have to be very very tight. Like seals without o-ring tight. See if it compresses into a homogeneous material. Especially if you can get so much pressure it causes 200-ish degrees of heat
When in pre / basic school, you put glue on your hands and rub your hands till it would form a big ball of dried glue. You can make and crush that one!
Glue together fish flakes (fish food). Make a fish rock. Get some Lutefisk from your Swedish neighbors and try that, too? Glue together sawdust - make particle board. Also, can you make dangerous hockey pucks from metal shavings?
Thanks for the video! If you haven't done so yet, do a search on "pressure sensitive adhesives" as there might be some that would be interesting for crushing? ;-)
If I understand correctly, the wood in paper has been stripped of lignin, the stuff that holds it together normally. Maybe try with wood chips/shavings/sawdust, to see if the lignin makes a difference
You could try "Smarties" or "PEZ" candy. They're manufactured by pressing powder into tablet/pill form; if you cut a logo into one of plates (with a slight draft angle for release) you can make a giant HPC candy.
Seen something like this before but for a different application. In the UK they processed waste paper from multiple sources where they shed the paper, soak the paper for 72 hours then pressed the paper to some value in PVC pipe. Am quite sure the PSI was far less than whatever you are using. Then they would cut it in 1-2 cm lengths and it was used to replace the use of coal in plants to generate electricity. The focus was to come up with a way to reduce what was going into the land fills and to be used as a cheaper replacement for coal. Don't know where the project ended up. With the global warming panicers it was likely killed.
There is a product from the 1970's called homasote. It is exactly what you made. 11inches of epoxy coated paper pressed into a 2.5inch thick sheet to be used as a wood sheeting alternative.
Maybe add a bit of gypsum powder to the paper load and dampen it just before pressing. Perhaps just a little school glue, glue the paper sheets together and press. That might not allow the glue to just get squeezed out and compromise the seal.
Have you heard about a material called "super wood" ? Basically cooking the wood to remove lignin and left cellulose behind, and then you compress the cellulose to get a a super strong material. The effort should be reasonable (takes about a week) and i think it would be very cool to see you make this material.
could make some crazy composite-materials from floor scrapings , bread, socks, pretty much anything that will fit in the tube (with a few drops of glue)
Fluffed out hemp or sisal rope, horse hair, pieces of rotan skewers are all fibrous materials that glue well together with wood glue and could form a real strong composite.
Differential Scanning Calorimetry (DSC), combustion calorimetry. Great undergrad lab! Probably publishable as a scholarly paper re paper and uncontained explosion versus contained ceramitization. The best Finish physical chemistry departrments in Finland: University of Helsinki (world class!) Abo Akademi University University of Jyvaskyla
Shred the paper, then add some erikeeper thinned with water (like 10-20%), let the paper mass soak the glue mixture and then press it. If you add the glue to the paper it doesnt have time to absorb the glue properly. Also you should try to mix aluminium oxide (you can get this from Motonet, its for sandblasting) with regular epoxy (mix well) and then press it into bulletproof disks. You may need to add some fiberglass to the mix to keep it together. Around 35mm disc can be enough to stop some rifle rounds.
You should see if this material is machinable. Also, try different amounts of glue, different types of paper, and different types of glue. Epoxy could cure inside the tool and make a really tough composite that would be cheap and possibly useful to someone.
Did someone suggest you add flour and water during the loading of the paper? or make a flour and water paste first then add that while loading the paper?
