Defects in PES film casting
문제 현상
Pores and uneven thickness appear when PES solution is cast into film
원인 분석
Solution concentration and viscosity too high or too low; solvent volatilization rate not properly controlled; hot air uneven during drying
해결 방법
Optimize the casting solution concentration and viscosity (adjust if necessary); control gradient drying conditions; optimize the air field uniformity of the casting machine
핵심 요약
PES film formation has strict requirements on every step of the process
