That’s what I get when google chemistry.
Can it pass in gas phase without burning?

I’d like to re-refine it so I can get transparent polymer at some level.
@marcelozp, I’m Brazilian and I can help you out with the translation. Give me a shout when you get the Portuguese version done.
Kind regards,
Lincoln
@marcelozp sound interesting! If you are, try to make it as simple and easy as possible so everyone (even with basic english) can understand.
Perhaps you can help out in this area but I see you already found that topic

I can help translate from portuguese to English
I can write a little guide about polymers, but I will need help translating it. If you help send me an email marcelozp@gmail.com
Perfect! –Thanks a lot
I’ll try to post in both languages ok?
PT: Você pode sim, mas terá que aquecer reprocessar todo o material causando assim novas rupturas de ligação química primária.
EN: Yes, but you’ll need to heat and reprocess all the material breaking chemical bond
Hi Guys, I know this is easier for you. But could you do it in english? In this way others (like me) can learn from it as well. And i’m quite curious!
Assim,
que quer dizer que uma vez que a cristalização foi feito não pode ser desfeito?
Sim.
Quando se fala de plásticos o processo de alteração de cor se dá pela mistura de um pigmento antes do processamento do material em um extrusora ou injetora, na maioria dos casos. Portanto o material adquiri a cor e essa moléculas se ligam quimicamente as moléculas do plástico, fazendo com que elas não possam ser separadas.
Agora quando se trata de material virgem ele tende a ser translúcido como as garrafas dágua. Porém ao ser injetada ela deve ser bruscamente resfriada até a temperatura ambiente para evitar a cristalização. Cristalização é um processo de ordenamento molecular que faz com que o material se torne opaco.
Você teve a idéia de diminuir o tamanho da molécula. Isso, além de indesejado devido a queda das propriedades mecânicas, impossibilitaria o processamento.
When it comes to color plastics changing process occurs by mixing a pigment before processing the material in a extruder or injection in most cases. Therefore the material acquires color and chemical linkage occurs between molecules and plastic pigment, so that they can not be separated.
when it comes to virgin material it tends to be translucent as water bottles. But to be injected, it should be abruptly cooled to room temperature to prevent crystallization. Crystallization is a molecular ordering process which makes the material to become opaque.
You had the idea to decrease the size of the molecule. This, besides the decrease of mechanical properties, make it impossible processing.
Hello Marcelo, can you please explain briefly in portuguese?
Is little hard to explain in english to me.
Plastics aren’t painted as metals part. There is a product mixed with original polymer that changes it color and you can’t extract then.
Thanks,
ok,
so transparent = virgin material.
But the effect will be the oposite. Sorry for my english.
If you want transparent you will need virgin material and fast cooling process
Thanks Mareclozp, I thought so but was not sure how, UV fine for me, relatively easy to test.
Yes you can do it by depolymerization. The best way, in my opnion, is using UV light. Sorry for my english.
