Poor Chemical Resistance of CMC
Fenómeno del problema
After immersion in acid, alkali and solvent, mechanical properties of CMC products decrease by >30%
Análisis de la causa
CMC has high affinity for specific chemicals and is eroded and swollen; CMC molecular chains are attacked by chemicals and broken
Solución
1)Select chemical-resistant grade; 2)Micro-crosslinking to reduce swelling; 3)Surface coating protection for products; 4)Add chemical stabilizer
Conclusión clave
Poor chemical resistance is caused by CMC chemical affinity; selecting chemical-resistant grade and coating are the key
