Analysis and Solution of Crystal Form Transition II→I of PB in pipe extrusion of pressure pipes
Fenómeno do problema
When producing pressure pipes by pipe extrusion, PB shows abnormal performance related to crystal form transition II→I.
Análise das causas
The main reason is that parameter fluctuation is too large in the aspect of crystal form transition II→I, leading to unstable processing.
Solução
Comprehensively solve the crystal form transition II→I problem from the perspective of formulation optimization.
Conclusão principal
The control of crystal form transition II→I of PB is the key link to ensure processing quality.
