Q

PTFE Compression Molding Bubbles

A

Pre-pressing degassing for PTFE bubbles is the primary process; 0.03% moisture content is the raw material red line; uniform loading prevents air entrainment.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PTFE Static Electricity Problem

A

PTFE's excellent insulation is accompanied by static electricity troubles; antistatic modification is the premise of application expansion; occasion assessment determines material selection.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent rec...

Q

PTFE Poor Dimensional Stability

A

PTFE dimensional management must follow material characteristics rather than metal habits; the 10-fold thermal expansion difference is a communication point; measurement at use temperature is a pragmatic method.; After confirming effectiveness, fix the parameters and practices into the work instr...

Q

PTFE Lining Deformation and Delamination

A

PTFE lining's thermal expansion mismatch is a structural contradiction; molding quality determines bonding reliability; negative pressure conditions are a severe test.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PTFE Bonding Difficulty

A

The only way out for PTFE bonding is surface activation treatment; sodium naphthalene treatment is the industry standard method; treatment validity management affects success rate.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process PTFE;bonding;surface energy;sodium naphthalene treatment;activation;composite

Q

PTFE Poor Wear Resistance

A

PTFE's low friction does not equal high wear resistance; filled modification is the premise of wear-resistant applications; PV value management is a design specification.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process PTFE;wear resistance;friction;filler;PV value;modification

Q

PTFE Cold Flow Creep

A

PTFE cold flow is an inherent weakness of the pure resin; filled modification is the standard countermeasure; seal design must reserve creep compensation.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process PTFE;cold flow;creep;seal;filling;deformation

Q

PTFE Overheating Degradation

A

PTFE's 380℃ is a double red line of performance and safety; local hot spots are more dangerous than average temperature; toxic gas protection is an occupational health requirement.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PTFE Filler Segregation

A

PTFE filler segregation affects the uniformity of wear resistance, thermal conductivity, and strength; mixing process is the foundation; handling management is the detail defense line.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PTFE;filler;segregation;mixing;glass fiber;uniformity

Q

PTFE Laminate Delamination

A

Cleanliness and pressure uniformity of PTFE laminates determine interlayer quality; grade compatibility is easily overlooked; non-destructive testing is quality assurance.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PTFE;lamination;delamination;bonding;contamination;grade
