Control of the biodegradation rate of PLA products
Fenómeno do problema
PLA products degrade too fast or too slowly in compost or soil.
Análise das causas
The degradation rate of PLA is affected by the environmental temperature and humidity, microbial activity, and the characteristics of PLA itself (crystallinity, molecular weight, additives).
Solução
Adjust the degradation rate by blending and adding degradation accelerators or inhibitors; control the crystallinity of the product.
Conclusão principal
The regulation of the PLA degradation rate is the key to achieving a balance between functionality and environmental protection.
