EVA hot melt adhesive stringing
Fenómeno do problema
The adhesive strings during application, affecting construction.
Análise das causas
Low adhesive temperature and high viscosity easily cause stringing; mismatched application distance and speed also produce it.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solução
①Appropriately raise the adhesive temperature; ②optimize the application distance and speed; ③select a low-stringing adhesive type; ④adjust the nozzle.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Stringing is a matching problem between construction parameters and adhesive type; temperature and operation are adjusted in coordination.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
