Praktische Antworten auf häufige Herausforderungen mit Kunststoffmaterialien

11636 Fragen
Q
CEF plasticization poor
A
Poor plasticization is caused by improper screw design; optimizing the screw and increasing the temperature are the key
Processing Machinery CEFpoor plasticizationscrew compression ratioshear rateprocessing temperature
Q
CEF internal inclusions
A
Inclusions are caused by raw material and environmental pollution; filtration and environmental control are the key
Production & Quality CEFinclusionraw material filtrationenvironmental cleanlinessrecycling sorting
Q
CEF hardness too low
A
Low hardness is caused by the softness of the material and excessive plasticization; adding fillers is the key
Molding Process CEFhardness too lowrigid fillerplasticizercrystallization control
Q
CEF flatness insufficient
A
Insufficient flatness is caused by shrinkage differences and stress; uniform cooling and annealing are the key
Molds & Tooling CEFflatnessshrinkage differenceuniform mold temperatureannealing treatment
Q
CEF internal unmelted particles
A
Unmelted particles are caused by insufficient plasticization; increasing the temperature and reducing the feeding are the key
Processing Machinery CEFunmelted particleplasticizing capacityprocessing temperaturescrew mixing
Q
CEF toughness insufficient brittle fracture
A
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is the key
Material Analysis CEFinsufficient toughnessmolecular weightcrosslinking controlcrystallization refinement
Q
CEF impact strength fluctuation large
A
Impact fluctuation is caused by unstable dispersed phase and crystallization; stabilizing the processing is the key
Molding Process CEFimpact fluctuationdispersed phase particle sizenucleating agentprocessing stability
Q
CEF chemical resistance poor
Q
CEF processing odor large
A
Large odor is caused by CEF decomposition and volatilization; temperature control and ventilation are the key
Material Analysis CEFprocessing odorvolatilesventilation and exhausttemperature control
Q
