Glass Fibre extruded pipe rough inner wall
Problembeschreibung
Glass Fibre extruded pipe inner wall roughness Ra>10μm, affecting fluid transport efficiency
Ursachenanalyse
Mandrel surface rough or worn; insufficient internal cooling causes inner wall melt not fully set; Glass Fibre melt elasticity causes uneven extrusion swell of inner wall
Lösung
1) Polish mandrel to Ra<0.4μm; 2) optimize internal cooling system, cooling water through mandrel; 3) reduce extrusion rate to reduce elastic recovery influence; 4) add small amount of low-elasticity resin to improve inner wall smoothness
Wichtigste Erkenntnis
Pipe inner wall roughness is caused by mandrel condition and insufficient cooling; polishing mandrel and internal cooling are key
