Praktische Antworten auf häufige Herausforderungen mit Kunststoffmaterialien

1343 Fragen
Q
Glass Fibre processing large odor
A
Large odor is caused by Glass Fibre decomposition and volatilization; temperature control and ventilation are key
Material Analysis Glass Fibreprocessing odorvolatilesventilation and exhausttemperature control
Q
Glass Fibre insufficient tensile strength
A
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grade is key
Material Analysis Glass Fibretensile strengthmolecular weightcoupling agentorientation control
Q
Glass Fibre low elongation at break
A
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
Material Analysis Glass Fibreelongation at breakmolecular weightorientation controlcrosslinking degree
Q
Glass Fibre fast UV aging
A
Fast UV aging is caused by photo-oxidation; UV absorber and HALS are key
Material Analysis Glass FibreUV agingUV absorberHALSradical scavenging
Q
Glass Fibre shrinkage rate unstable
A
Unstable shrinkage rate is caused by batch difference and temperature fluctuation; raw material and temperature control are key
Material Analysis Glass Fibreshrinkage ratebatch differencetemperature control stabilitycrystallization consistency
Q
Glass Fibre poor weather resistance
A
Poor weather resistance is caused by photo-oxidation; UV+HALS+antioxidant triple protection is key
Material Analysis Glass Fibreweather resistanceUV absorberHALSphoto-oxidation
Q
Glass Fibre product dimensional change during long-term storage
A
Dimensional change is caused by physical aging; annealing treatment and slight crosslinking are measures to stabilize dimensions
Material Analysis Glass Fibre dimensional stabilityphysical agingannealingsecondary crystallizationslight crosslinking
Q
Poor interfacial bonding between Glass Fibre and filler
A
The elastomer/filler interface needs the dual action of coupling agent and compatibilizer, otherwise the filler plays a negative effect
Material Analysis Glass Fibre fillerinterfacial bondingcoupling agentcompatibilizerfiller dispersion
Q
DSTDP low flexural modulus
A
Low flexural modulus is caused by material softness and insufficient filler; adding rigid filler is key
Material Analysis DSTDPflexural modulusrigid fillernucleating agentcrystallinity
Q
DSTDP large processing smoke
A
Large smoke is caused by volatiles evaporation; temperature reduction and exhaust are key
Material Analysis DSTDPprocessing smokevolatilesexhaust systemtemperature reduction
