废旧地膜回收利用方法的研究

Study on Recycling Method of Waste Plastic Film

随着经济的发展和科技的进步,高分子材料给我们的生活带来了无穷的便利。聚乙烯作为使用领域最广、使用量最大的高分子材料,使用后的废旧聚乙烯塑料对环境带来的危害日益严重,故对其回收再利用的研究成为热题。而废旧地膜的材质为聚乙烯,单纯的焚烧和掩埋不能彻底解除对环境带来的危害,因此通过查阅文献,总结了6种废旧地膜回收利用的更加经济实用的方法,并结合其生产技术对今后的塑料回收提出展望。

With the development of economy and the progress of science and technology,polymer materials have brought infinite convenience to our life.As the most widely used and most widely used polymer material,the waste polyethylene plastic after use has brought more and more serious harm to the environment,so the research on its recycling has become a hot topic.However,the waste plastic film is made of polyethylene,which can't be completely removed by incineration and burying.Therefore,six more economical and practical methods for recycling waste plastic film were summarized by consulting the literature,and the prospect of plastic recycling in the future was proposed based on its production technology.
