Q

Curing agent ratio error

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), time...

Q

Embrittlement

A

The essence of embrittlement is that the material's toughness reserve declines to the point of being unable to meet use requirements. The control key is the 'three temperatures'——processing temperature (avoid excessive degradation), drying temperature (avoid too low leaving residual moisture and ...

Post-Curing Deformation

A

The core of curing abnormality is that the rate and degree of the crosslinking reaction deviate from the optimal window.
