Not again about boosting please

[lodro]

Hello everyone,

Devil will find works for idle hands. Boosting rubbers, heavy masturbation, and more unworthy amusements to kill time.
Yes, l can offer much better occupations for your hands. E. g. how to get the ball wobbling on travel just by manual compulsion. The trick worthy to try anyway.

Ha !!!! It is for men like you I have got this couch in my office.
Anybody who claims that heavy masturbation is an unworthy amusement to kill time has had a doubtful, probably heavy christian upbringing.
I reckon about 35 sessions on my couch would fix this . You would feel liberated and might even take up a bit of boosting,
😂😂😂

( mind you, at my rates these days you also would be broke 😎 )

I sure hope you clean that couch of yours thoroughly after every session with your clients. 😁

Lodro, you are not helping. Neither is Upside Down Carl.
Shame on the both of you for promoting this garbage.
Liquids, oils, water etc, do not compress much. Gas compress and will expand back.
Water doesn't compress much at all.
There is a value called bulk modulus for different fluids. The bulk modulus is an indicator of how compressible a fluid is
https://en.wikipedia.org/wiki/Bulk_modulus
I know that most of you will not understand this. What is worse is that most of you will not even try and remain ignorant.

The simple answer is that you don't fill your tires with liquids. You fill them with air.

Lodro did not test whether the "boosted" rubbers are really faster and spinnier. Isn't that is what is important? Do you really care about the doming effect?

My point about the water is that, if water makes the sponge dome, and does not have any useful boost effect, then, doming is simply not an indication of boost effect.

Of course you are correct with what you are saying. I am just pointing out that something that expands the sponge may or may not create a beneficial effect on the performance of the sponge/rubber.

I have used the 4th corner of this rubber to make the ""water test""" and , as we knew , it shows absolutely no doming or indeed
any other reaction. It simply gets wet - and then dry again.

But of course, like the photos show , the other 3 "treatments " do show reactions but I want to make it clear that
we are only talking about the reactions that IS SHOWN !!!!
What influences , if any, these treatments have on bounce, speed, spin etc etc is a completely different animal.

I was wondering if booster is a plasticizer and has little to do with being a liquid or gas in it's operation. Does anyone know the actual chemical composition of the popular boosters like Falco Tempo Long or Haifu Seamoon?

I do suspect that this is might be of the equation. I also think that booster also give the desirable mechanical effect of stretching the topsheet (due to expanded sponge), besides whatever structural effect it has on the sponge (just a guess, I might be wrong).

I do wish to know the chemical composition of boosters as well...

if you start a new thread,"""""" I do wish to know the chemical composition of boosters """""", you will get better exposure and more answers.
The basic formula is well known

Like what? Only the normal and horizontal coefficients of restitution matter. No one bothers to test that.

USDC, you are definitely not helping. You should be asking for proof that "doming" is beneficial. TT forums have too much opinion and not enough fact.

From where I sit, it looks like the moderators on TT forums allow the BS to pass because if the posters had to have facts, there would be few people posting except those posting videos or commenting on them.

Someone on Bilibili found a patent application for a booster product. The primarily ingredients were olive oil, sodium bicarb, and Vit E. The oil is just the solvent that carries the active ingredient, which is the bicarb. The oil soaks into the sponge, carrying with it the solute bicarb. Bicarb then becomes H2O + CO2 gas, which gets trapped within the sponge and is slowly released. It's the trapped gas increasing the pressure within the bubbles in the sponge that gives the extra kick to boosted rubbers. The Vit E is used to prevent sedimentation.What this suggests is that the booster effect will reduce both with time and use, which we already know. What we also know is that oils don't evaporate, so eventually a rubber will be so soaked with oil that it'll fill the gas bubbles, then the sponge will permanently go dead.I also surmise that the dense Chinese sponge prevents gas leak better, which is why they react better to boosting.

Interesting theory.
My burning question though is : "How can the oil get IN, but the gas can not get OUT" ????

Not fair !!!
All I posted were facts.
Namely 3 pieces of rubber off -cuts with 3 different treatments. Nothing more and nothing less.

Furthermore, when joining this forum no qualifications were demanded of me or anybody else.
No IQ test was needed and no trick questions needed to be solved.
This means even complete half senile old gits like myself can post here. 😂😂😂
Life is hard 🤣

Oil can soak through, the same reason your skin can absorb oil but you can't blow air into it. Note that bicarb is not a gas, it only becomes one after acquiring an H+ ion and then breaks down into H2O and CO2 gas.

I usually cut and glue a rubber to a blade to test it out.

Afterward I apply booster right on top of the rubber cement on the rubber. The rubber cement and booster mixes to form a thicker, stickier glue substance.

Im just wondering, is most of the booster making it down to the sponge? Or is it being trapped by the rubber cement?

Hello to everyone, I am new aboard.👋
Cement can stick very easily to rubber, it is one of the reliefs with which cement works best.

Rubber cement is basically speed glue, I probably wouldn't use it in combination with booster.

Wy not? Seems to work fine. But im just not sure how much booster is making it down

RUBBER MATERIALS IS A WONDERFUL ENDOWMENT OF NATURE TO MAKE ALL THE PONGERS HAPPY FOREVER, I believe strongly.

INTRODUCTION: The sciencific background of the "oil absorbtion" effect.

Volatile oxygen molecules can't get into the rubber molecular grid because of a very short contact time.
On the other hand, liquid oily substancies, being applied on rubber sheet surface, will eventually get into the rubber material by force of the molecular diffusion.

Be happy.

How does that help?

It depends on how much rubber cement you apply to the sponge and if the sponge will absorb a liquid at all.
I think you are wasting your time.

Now you will have to do exactly what I did. You have to repeat the experiment on the 2 patches, the one on the left and the middle one.
The patch on the left has the glue applied before being treated with the oil and YES, the glue is inhibiting the action.
The reason however why i suggest you do your own experiment is because you are using speedglue which may show completely different
results

If the baby oil or other boosters are absorbed by the rubber via molecular diffusion , which I can accept, there will be no residual pockets
of fluid in the sponge that lead to an over saturation of fluids in the sponge after multiple applications. as postulated in # 29.
I guess the sponge would simply not take on any more of the fluid once saturated
