Q

CPE Pellets Bridging in the Hopper and Not Feeding

A

Feeding management affects production stability

Production & Quality CPE bridging

Q

TPU Temperature Resistance Upper Limit

A

The temperature resistance upper limit of TPU is clear; 80-90°C is the long-term red line, and short-term 110-120°C does not mean long-term usability; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Production & Quality TPU; temperature resistance; 80-90°C; 110-120°C; long-term

Q

PVDF Pipeline Welding Process Defects

A

The three elements of PVDF welding are temperature control, time control, and pressure control; cleanliness and alignment are equally indispensable; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVDF and PFA Selection Confusion

A

PVDF and PFA are selected by the boundary of temperature and purity, and 150℃ is the key watershed; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVDF Failure in Strong Alkali and Ketone Media

A

PVDF chemical resistance has clear boundaries; strong alkali and ketone media require material change or verification; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVC Transparent Sheet Gel Particles

A

PVC transparent sheet gel particles = 'resin fish-eyes + plasticization': many fish-eyes in the resin itself and insufficient plasticization are the two sources; transparent sheet must be controlled from both resin selection and plasticization process.

Production & Quality PVC; transparent sheet; gel particle; fish-eye; resin

Q

PVC Pipe Rough Inner Wall

A

For PVC rough inner wall, check 'die head convergence and plasticization': confluence marks and poor plasticization are the two major roots; inner wall quality is the mirror of die head design and plasticization uniformity — grasp from both die head and formula.

Production & Quality PVC; pipe; rough inner wall; die head; plasticization

Q

PVB Cooling and Surface

A

PVB cooling management balances surface and dimensions; embossing is a functional treatment; detection verifies optical quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PTFE Cooling Crystallization Control

A

PTFE cooling manages the dual goals of crystallinity and stress; 50℃/h is the balanced rate; curve records support quality traceability.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Production & Quality PTFE;cooling;crystallinity;strain;cracking;50℃

Q

PTFE Holding Pressure Time Matching

A

The matching relationship between PTFE holding pressure time and pressure must be followed; section verification of internal quality; quantified records solidify experience.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
