In the production process, extruders sometimes have poor plasticization, what is the reason?

plasticizing bad

1, plasticizing adverse phenomenon

(1) plastic layer surface phenomenon has toad skin type.

(2) The temperature control is low, the instrument pointer reflects the temperature is low, and the actual measurement temperature is also low.

(3) The plastic surface is black, and there are tiny cracks or small particles that are not plasticized well.

(4) The glue of the plastic is not well stitched, and there is an obvious trace.

2, the cause of poor plasticization

(1) The temperature control is too low or the control is not appropriate.

(2) There are resin particles that are difficult to plasticize in plastics.

(3) The operation method is improper, the screw and traction speed are too fast, and the plastic is not completely plasticized.

(4) When the plastic is mixed unevenly or the plastic itself has quality problems.
