Several steps of identifying waste plastics in granulator

Several steps of identifying waste plastics in granulator

The steps for the granulator to identify waste plastics are as follows:

1. Hand feel (weight, sensitivity and smoothness);

2. Look at the color;

3. Look at the brightness (transparent material can be removed in this step);

6. Wire drawing (the wire drawing with more CaC03 is certainly not good, and the reinforced wire cannot be pulled out).

5. Ignition (observe whether the flame color is smoking, whether it contains off fire combustion or no combustion at all);

6. Smell the smell (the smell of various plastics is different, including flame retardant, etc.);
