Hydrolytic Aging of CMC
ظاهرة المشكلة
Mechanical properties of CMC products decrease by >25% in hot and humid environment
تحليل الأسباب
CMC contains polar groups that hydrolyze and break chains under hot and humid conditions; ester bonds/amide bonds etc. are sensitive to water
الحل
1)Select low-polarity content grade to reduce hydrolysis tendency; 2)Add anti-hydrolysis stabilizer; 3)Coat the product surface with a waterproof layer
الخلاصة الأساسية
Hydrolytic aging is caused by polar groups being sensitive to water; selecting a low-polarity grade is the key
