Q

PVC Black Specks and Burnt Particles

A

PVC black specks = 'carbonized retained material falling off': dead corner treatment is the core, purging is more effective than parameter adjustment; intermittent, stubborn black specks are the typical fingerprint of equipment dead corners — without finding the root cause on the equipment, black...

Q

PVC Processing Yellowing (Early Thermal Degradation)

A

PVC yellowing is a 'degradation alarm' rather than ordinary color difference: conjugated polyene coloring indicates de-HCl has already occurred, and it will autocatalytically worsen; temperature must be lowered immediately, the stabilizer system checked, dead corners cleaned — delaying one minute...
