建筑白色污染防治方案及环保塑料膜的研究
|
摘要
建筑行业的快速发展为国内的城市化与现代化进程做出了巨大贡献,但是,建筑固体废弃物给自然环境带来的负面影响却无法忽视。在诸多种类的建筑固体废弃物中,由建筑型材、玻璃幕墙和装饰板等建材表面的软质塑料保护膜在废弃后带来的白色污染对环境的影响最大,也是这几年国家逐渐加大力度治理的环境问题之一。在简述了建筑白色污染的来源的基础上,分析了建筑白色污染对环境的危害,阐述了国内处理废弃的软质塑料保护膜主要方法,研究了以光降解型塑料、生物破坏性塑料和全生物降解塑料为代表的可降解材料,分析了三种材料取代传统建材塑料保护膜材料的可能性,提出了建筑白色污染的防治和环保塑料膜的推广方案。
The rapid development of the construction industry made great contributions to the process of urbanization and modernization in China,but the negative impact of solid waste on the natural environment cannot be ignored. Among the types of solid waste in construction,the white plastic pollution caused by the soft protective plastic film on the surface of building materials such as building profiles,glass curtain walls and decorative panels had the greatest impact on the environment,and the country increased gradually in recent years. Based on introduction of the origin of white pollution in the building briefly,the harm of the white pollution on the environment was analyzed,and the main methods of treating the waste soft plastic protective film were expounded in China. The photodegradable plastics, biodegradable plastics and biodegradable plastics as the representative of the biodegradable materials were studied, the possibility of replacing three kinds of materials with plastic protective film materials of traditional building materials were analyzed,the prevention and control scheme of building white pollution and the promotion scheme of environmental protection plastic film were put forward.
