일반적인 플라스틱 재료 문제에 대한 실질적인 답변

2025 질문
Q
Poor EAA plasticization
A
Poor plasticization is caused by improper screw design; optimizing the screw and raising temperature is key
Processing Machinery EAApoor plasticizationscrew compression ratioshear rateprocessing temperature
Q
EAA internal unmelted particles
A
Unmelted particles are caused by insufficient plasticization; increasing temperature and reducing feeding is key
Processing Machinery EAAunmelted particlesplasticizing capacityprocessing temperaturescrew mixing
Q
Insufficient EAA mixing
A
Insufficient mixing is caused by improper screw design; increasing the mixing section is key
Processing Machinery EAAinsufficient mixingscrew mixing sectionkneading blocksside feeding
Q
Difficult machine purging of EAA
A
Difficult purging is caused by the strong adhesion of EAA; PE flushing and temperature reduction are the key
Processing Machinery EAA difficult purging adhesion PE flushing dedicated purging material
Q
Residual material after EAA material changeover
