Respostas práticas para os desafios comuns dos materiais plásticos

11636 perguntas
Q
EEA Insufficient Flatness
A
Insufficient flatness is caused by shrinkage differences and stress; uniform cooling and annealing are key
Molds & Tooling EEA flatness shrinkage difference uniform mold temperature annealing treatment
Q
EEA Internal Unmelted Particles
A
Unmelted particles are caused by insufficient plasticization; increasing temperature and reducing feeding are key
Processing Machinery EEA unmelted particles plasticizing capacity processing temperature screw mixing
Q
EEA Insufficient Low-Temperature Performance
A
EEA low-temperature performance is determined by EA content; selecting a high EA grade is fundamental
Molding Process EEA low temperature EA content low-temperature toughness annealing grade selection
Q
EEA Insufficient Toughness, Brittle Fracture
A
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is key
Material Analysis EEA insufficient toughness molecular weight crosslinking control crystallization refinement
Q
EEA Large Impact Strength Fluctuation
A
Impact fluctuation is caused by unstable dispersed phase and crystallization; stable processing is key
Molding Process EEA impact fluctuation dispersed phase particle size nucleating agent processing stability
Q
EEA Poor Chemical Resistance
A
Poor chemical resistance is caused by EEA chemical affinity; selecting chemical-resistant grades and coating are key
Material Analysis EEA chemical resistance chemical attack slight crosslinking surface coating
Q
EEA Strong Processing Odor
A
Strong odor is caused by EEA decomposition and volatilization; temperature control and ventilation are key
Material Analysis EEA processing odor volatiles ventilation and exhaust temperature control
Q
EEA Internal Shrinkage Voids
A
Shrinkage voids are caused by thick-wall shrinkage and insufficient holding; extending holding is key
Molds & Tooling EEA shrinkage void thick wall holding time gate freezing
Q
EEA Large Creep Deformation
A
Large creep is caused by the elastomer nature; slight crosslinking and rigid fillers are key
Material Analysis EEA creep slight crosslinking high molecular weight rigid filler
Q
EEA Poor Antistatic Effect
A
Poor antistatic effect is caused by insufficient addition; increasing antistatic agent is key
Molding Process EEA antistatic antistatic agent surface resistance migration rate
