Sorun Belirtisi
Arrow-shaped and V-shaped crosslinked gel spots appear on the film surface.
Neden Analizi
The material is retained and crosslinked in the barrel/head (oxidative gel); formed by heat preservation during shutdown or retention in dead corners.
Çözüm
①Shorten residence time and standardize shutdown; ②clean dead corners; ③fully purge at startup; ④add antioxidant for evaluation if necessary.
Temel Çıkarım
Crosslinked gel particles = retention oxidation; manage shutdown and dead corners well.
