Fenómeno do problema

COF changes with storage time.

Análise das causas

Slip agent continuously blooms and migrates; high temperature speeds migration.

Solução

①Control addition amount; ②store at constant temperature; ③re-test COF after aging; ④select a migration-stable system.

Conclusão principal
