无需进行任何人工处理便能自行降解或粉化的无公害地膜,已由上海有机化学研究所研究成功,最近通过鉴定。无公害降解地膜采用聚乙烯为基质,再添加由光氧化降解剂、氧化降解促进剂、生物降解剂和降解控制剂等降解助剂组成,采用独特的制备工艺制备,成本低廉,适合大规模生产。科研人员将研制的10余吨地膜在上海郊区4000余亩蔬菜、瓜果和花卉田地试用,经过地膜覆盖所有田地的作物实现了与普通地膜一样的保温、高产的效果。在3至6个月后,留在地里的地膜在阳光照射下能自行降解崩裂或完全粉
Pollution-free plastic film that can be degraded or pulverized without any manual treatment has been successfully researched by Shanghai Institute of Organic Chemistry and recently passed the appraisal. Pollution-free plastic film using polyethylene as matrix, and then added by the photooxidative degradation agent, oxidative degradation accelerators, biodegradable agents and degradation control agent and other additives, the preparation of a unique preparation process, low cost, suitable for large-scale production . Researchers will develop more than 10 tons of plastic film in the suburbs of Shanghai more than 4,000 acres of vegetables, fruits and flowers field trial, after mulching all fields of crops to achieve the same as the ordinary film insulation, high yield effect. After 3 to 6 months, the mulch left in the ground can self-degrade the cracked or completely powdered
