Why didn't the liquid expand while it was in the drum? 🤔

Polyol + isocyinate. Mix for 1 minute. Pour out. Reaction going since they began mixing. Takes a few minutes for reaction to complete. Literally how all foams are made.

so that's how it is yeah 👍

Because it was in the drum for all of 5 minutes after the two parts were mixed and that was a time lapse of several hours.

How many people have been cut by that band saw?

Those kinds of foams are usually A/B types that you need to mix two different chemicals, or more, together and then you have to dump them into the mold, and has a slight delay in reaction.

You have around 30 seconds to mix it before expansion, 2 component foam, they put it into the barrel mix it then pour it.

It is polyurethane, made of 2 components that were previously mixed. The expanding reaction takes place after 8 to 30 seconds of being mixed, depending on the formulation.

Buat kasur empuk pake cairan

Iya bikin kasur

Maybe the reaction happened with the contact of ground not in the container most probably

maybe so

Nothing to worry about, just someone casually putting his arm and body in front of a saw.

Itu cairan aoa sih ko bisa mengembang gitu

Kurang tau juga ya

Ever heard of the word ‘heat’ ?

Kok bisa ngembang ya

It has a time reaction so if they mix certain types of chemicals they have a time window that determinates ho much thy can take it on the drum. An other thing is the surface area that starts to loose faster the diluents gasses in wider surface and probably start the reaction.

Polyol in blue drum + isocyanate in big vessel = Reaction starts post pouring

Bikin spon atau apa ini kak?

Busa kek kasur

so......tell me why my Tempurpedic costs $5000 ?

Maybe the force of it being dumped mixed the chemicals? Or mayhaps it was expanding in the bucket, but very slowly because there wasn't enough surface area. Or there's a small window between the chemicals being mixed and the reaction starting like with apoxy

What do you mean didn’t? BITCH THE LIQUID DID EXPAND TF?! ENGLISH DO YOU SPEAK IT?

jdi tau cara pembuatannya deh

Sama aku juga jadi tau

Itu memuai pas di panaskan ya?

@yosefikr Iya bener banget

India labor cheaper than China or what?

Agak gimana ya ini mah

@alanazahiraa01 Gimana tuh kak

The principle of foam expansion relies on either a chemical reaction that produces gas or the controlled expansion of a liquid due to a blowing agent.

Menarik banget sih ini

@bangkribolagi Sangat menarik

jadi mengembang yaaa

Iya kan jadi busa

Bikin sponn ya ini

It wasn't activated. They hadn't catalysed (activated) it and aeration helps the process go faster...

Km nanya kah nder?😭 ya mana saya paham

Sangat menarik banget

Jadi mengambng yaa

Menarik pisan yaa

@grok explain

I

Heat

Sangat satisfying ya
