PA hydrolysis and performance decline in hot water environment
Problembeschreibung
PA hydrolysis and performance decline in hot water environment
Ursachenanalyse
Cellulose acetate butyrate hydrolysis reaction accelerates in hot water, molecular chain breakage
Large mechanical property decline after hot water immersion
PA66 hydrolyzes faster than PA6
Long-term hot water use requires hydrolysis-resistant modification
The higher the hot water temperature, the faster the decay rate
Lösung
Select hydrolysis-resistant PA grades or modified grades
Hot water applications require long-term immersion verification
PA12 has good hot water resistance, preferred
Lower the use water temperature to slow decay
Add anti-hydrolysis agents
Wichtigste Erkenntnis
PA hot water resistance requires selecting suitable grades and verification
