Q

Pulse effect periodic density variation appears in PTFE sintered parts

A

The essence of uneven density is inconsistent distribution or densification of the material during the '2079851475616104453; it is necessary to optimize the feeding method and pressure transmission.

Q

Post-curing cracking

A

The core of curing abnormality is that the rate and degree of the crosslinking reaction deviate from the optimal window. The adjustment idea is the "three-element method": formulation (precise metering of catalyst/curing agent), temperature (precise control of mold and material temperature), and ...

Q

Low-temperature embrittlement of the product

A

The essence of embrittlement is that the material toughness reserve drops to a level that cannot meet the use requirements. The key to control is the "three temperatures" — processing temperature (avoid excessively high degradation), drying temperature (avoid excessively low residual moisture and...

Q

Insufficient tensile strength

A

The core cause of insufficient mechanical properties is insufficient material bonding or degradation, and the sintering/curing process needs to be optimized and the raw material quality controlled.

Q

Fibers lifted when tearing off process peel ply

A

The essence of interlayer separation problems is insufficient interface bonding force, requiring systematic improvement from three aspects: impregnation quality, interlayer cleanliness, and process parameters.

Q

Improper raw material temperature (foaming power affected by temperature)

A

Temperature control is a key parameter of the foam '2079851475616104453; it is necessary to ensure that the temperature is accurate, uniform, and stable to guarantee product quality consistency.
