Can waste rubber be recycled like plastic?

First of all, answer your question: waste rubber can't be recycled like plastic.

Of course, plastic here refers to thermoplastics,

Because the molding of rubber (and thermosetting plastics) is a process of chemical reaction (molding by chemical curing reaction)

Thermoplastics are formed by physical solidification (that is, the dynamic change process from heated flow to cooled solid state)

Under nagging, there are white spots on your section and your toughness is poor.

1, white spots are most likely related to the uneven dispersion of fillers, and have little to do with reclaimed rubber.

2, toughness is not good, there are many reasons, such as uneven dispersion of filler, mixed with reclaimed rubber, unreasonable coordination, insufficient vulcanization and so on. There are many reasons.

Finally, talk about the regeneration of waste rubber.

Rubber products are cured by chemical crosslinking (vulcanization) of raw rubber, which means that this process is a chemical change process, not a physical change, so its regeneration is more complicated.

At present, the main methods are:

1, directly mechanically crushed, or mechanically crushed after freezing, so the obtained product is called rubber powder, which can be used as a filler in new materials and can also be used for toughening plastics;

2, mechanical crushing first, and then desulfurization by desulfurization tank (that is, breaking chemical bonds);

3. There are many new sulfur breakers, which can be used more in NR\BR\SBR;

Generally speaking, the performance of reclaimed rubber is not as good as that of new material, but according to the actual use requirements of the product, it can be mixed in a proper amount to reduce the cost and even improve the process convenience. ...
