Surface Blooming of CMC
Problembeschreibung
White frost-like low-molecular substances exude on the surface of CMC products, affecting appearance
Ursachenanalyse
Low-molecular components in CMC migrate to the surface and exude during storage; lubricant or plasticizer supersaturated exudation
Lösung
1)Select high-molecular-weight CMC to reduce low-molecular substances; 2)Reduce lubricant addition to a reasonable level; 3)Clean the product surface and then detect the source
Wichtigste Erkenntnis
Blooming is caused by low-molecular migration and exudation; selecting a high-molecular-weight grade is fundamental
