Glass Fibre vacuum section material overflow
Sorun Belirtisi
Glass Fibre extrusion vacuum section material overflow, vent hole clogged
Neden Analizi
Glass Fibre melt viscosity low, overflows at vacuum section; vacuum section temperature too high, viscosity lower, aggravates overflow; vent hole design improper
Çözüm
1) Reduce vacuum section temperature 5-10°C to raise viscosity; 2) add baffle above vent hole to prevent overflow; 3) raise screw speed to accelerate conveying and reduce residence
Temel Çıkarım
Material overflow is caused by low melt viscosity; cooling and adding baffle are key
