New technology for production of poly lactic acid is a kind of new material of bio based biodegradable with completely independent intellectual property rights, the floor production in Henan Dancheng Jindan Technology Co. ltd.. This is a disruptive technology, the perfect solution to the production of lactic acid by lactic acid from corn, synthesis of polylactic acid, poly lactic acid production by fully biodegradable products industry chain construction, can completely solve the troubled world of "white pollution" problem of environmental protection and society plays an important role in promoting development. At the same time, radiation can promote the rapid development of agriculture and industry, food, medicine, new materials and other industries, will likely rise triggered a series of independent industry. Over the years, plastics, fiber and medical materials used by people are all oil derivatives. They are not degradable and consume a lot. At present, China consumes 6 or 70 million tons per year, and only 7 million tons for bags and plastic bags. The mass listing of plastics has brought great convenience to people, but its non degradation also brought serious environmental pollution. At present, the two pollution caused by plastic waste encircling City, plastic incineration, and soil damage caused by agricultural plastic film have become a global problem. At the same time, the non renewable oil also makes the search for alternative petroleum based plastics is imperative. R & D team, China academician of the Academy of Engineering School of environment Nanjing University professor Zhang Quanxing and professor of Nanjing University, doctoral tutor Li Hong said: Bio based material polylactic acid with non-toxic, non irritating, high heat resistance, plasticity and characteristics of good processing performance, is the most promising new materials to replace petroleum based plastics. Dancheng is located in the Henan Polytron Technologies Inc with the Nanjing University, Nanjing University of Technology, one of the "production, learning and research," powerful alliances, the establishment of innovation strategic alliance. Nanjing University national organic poison pollution control and resource engineering and Technology Research Center for research and development of "green biomass organic guanidine catalytic synthesis process of lactide, polylactic acid new technology" to solve the current polylactic acid material and the traditional plastic material of high production cost, poor processing performance; the use of environmentally friendly organic guanidine catalyst, completely at present, poly lactic acid production using stannous solution catalyst (stannous octoate and stannous chloride) two pollution problems caused by the product, is the world's first, to fill the gaps in the world, with the international advanced level, known as a new green revolution in the field of materials, has received great attention in the international trade and competition chase.
