LDPE Agricultural Film
Fenómeno do problema
Agricultural film powders and breaks after one season of use; uncolored film without a weather-resistant system has a short life
Análise das causas
LDPE has poor UV resistance, and agricultural film must have a UV stabilization system added; greenhouse film also needs anti-fog drop and heat preservation functions; thickness and stabilizer content determine the service life; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
① Select grades containing UV stabilizers for agricultural film; ② add anti-fog drop and heat preservation functions to greenhouse film as needed; ③ select thickness and stabilization system according to service life; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
The life of agricultural film is built up by stabilizers; UV system plus functional additives, with the formulation set according to service life; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
