Q
Glass Fibre processing temperature fluctuation
A
Temperature fluctuation is caused by improper temperature control system; PID tuning and heater band replacement are key
Molding Process Glass Fibretemperature fluctuationPID tuningheater bandthermocouple
Q
Glass Fibre hardness too low
A
Low hardness is caused by material softness and excessive plasticization; adding filler is key
Molding Process Glass Fibrelow hardnessrigid fillerplasticizercrystallization control
Q
Glass Fibre impact strength large fluctuation
A
Impact fluctuation is caused by dispersed phase and crystallization instability; stable processing is key
Molding Process Glass Fibreimpact fluctuationdispersed phase particle sizenucleating agentprocessing stability
Q
Glass Fibre surface stress whitening
A
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
Molding Process Glass Fibrestress whiteningorientation stressannealing treatmentstress concentration
Q
Glass fiber sizing agent mismatched with matrix
A
Sizing agent mismatch is caused by improper type selection; selecting matrix dedicated sizing agent is key

Q
Glass Fibre internal coarse crystallization
A
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key
Molding Process Glass Fibrecoarse crystallizationspherulite refinementnucleating agentcooling rate
Q
Glass Fibre large compression set
A
Large compression set is caused by insufficient crosslinking; raising crosslinking degree is key

Q
Glass Fibre extruded film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell differences; coat-hanger die and gap fine adjustment are key
