Glass Fibre surface blooming exudation
Problembeschreibung
Glass Fibre product surface exudes white frost-like low-molecular substance, affecting appearance
Ursachenanalyse
Low-molecular components in Glass Fibre migrate to surface and exude during storage; lubricant or plasticizer supersaturated exudation
Lösung
1) Select high molecular weight Glass Fibre to reduce low-molecular substances; 2) reduce lubricant addition to reasonable level; 3) clean product surface then detect source
Wichtigste Erkenntnis
Blooming is caused by low-molecular migration exudation; selecting high molecular weight grade is fundamental
