该项目是一种通过表面光聚合法制备的新型功能性塑料棚膜。其原理是通过表面聚合法在PE膜外表面嫁接聚合两层亲水层与厚膜形成永久性连接,从而赋予该膜长期的无滴性能。该产品的主要性能指标:长效无滴聚乙烯膜小样无滴期大于24个月,中试样无滴期大于12个月;

This project is a new type of functional plastic film prepared by surface photopolymerization. Its principle is through the surface polymerization method in the PE film outer surface graft polymerization two hydrophilic layer and the thick film to form a permanent connection, thereby giving the film long-term non-drip performance. The main performance indicators of the product: long-term non-drip polyethylene film sample drip-free period of more than 24 months, the sample drip-free period of more than 12 months;
