PAN solvent residue affecting carbonization
Sorun Belirtisi
Residual solvent in PAN precursor volatilizes during carbonization, causing pores
Neden Analizi
Insufficient water washing after coagulation; incomplete solvent volatilization during drying
Çözüm
Increase the number of water washing stages and temperature (stepwise heating water washing); extend drying time and increase temperature; test residual liquid content <0.1%
Temel Çıkarım
Solvent residue is an important source of carbon fiber defects
