摘要:
A microwave processing device/system can create strong temperature gradients in biodegradable polymer material. Novel physical phenomena caused by the heated particles cause local changes in viscosity and flow, leading to high mass transport and current densities in activated polymer matrix materials and to dramatically shorter reaction times and solvent-free reaction conditions. Advancements in the process speed and quality of packaging films in general can be achieved by increasing the polymeric amorphous to crystalline ratio, especially with regard to the claimed methods for manufacturing and sealing biodegradable packaging films. Micron-size particles or nanoparticles in the processed materials can interact with microwaves of different frequencies and intensities to create intentionally varied local material property changes to create an tunable flexible packaging product that is sustainable and "green." Related systems, apparatus, methods, and/or articles are also described.
摘要(中):
微波处理装置/系统可在可生物降解的聚合物材料中产生强烈的温度梯度。 由加热的颗粒引起的新的物理现象引起粘度和流动的局部变化,导致活性聚合物基体材料中的高质量传输和电流密度以及显着更短的反应时间和无溶剂的反应条件。 通常可以通过增加聚合物非晶态至结晶比来实现包装膜的加工速度和质量的进步,特别是关于制造和密封可生物降解的包装膜的要求保护的方法。 加工材料中的微米级颗粒或纳米颗粒可与不同频率和强度的微波相互作用,以产生有意改变的当地材料性质变化,从而创建可持续和“绿色”的可调谐软包装产品。 还描述了相关系统,装置,方法和/或制品。
