摘要
随着科技的发展,塑料在社会生活中如医疗、农业和包装等领域得到广泛应用。在上个世纪,人们就为塑料行业的发展做出了巨大的努力,各种塑料的发明应用层出不穷,也备受青睐。在包装领域塑料的使用量非常大,还逐年大幅度递增。然而,大量不可降解塑料的使用,带来了愈发严重的白色污染,各种包装用塑料堆积成山,更多的采用焚烧的处理方式,但与此同时会产生大量的有害气体。随着人们环保意识的增强和大自然平衡的需要,可降解塑料诞生了,这可谓是塑料行业一重大突破。
With the development of science and technology,plastics have been widely used in social life,such as medical treatment,agriculture and packaging.In the last century,people have made great efforts for the development of the plastic industry,and the invention and application of all kinds of plastics emerge in endlessly and are also favored.In the field of packaging,the use of plastics is very large,but also greatly increased year by year.The original use is good transparency,but also very durable non-degradable plastics.However,the use of a large number of non-degradable plastics has brought more and more serious white pollution,a variety of packaging plastics piled up into mountains,more using incineration treatment,but at the same time will produce a large number of harmful gases containing chlorine elements.Body With the enhancement of people's awareness of environmental protection and the need of balance of nature,degradable plastics have been born,which can be described as a major breakthrough in the plastic industry.
