Biodegradable plastic granulator

&The main countries that produce degradable plastics include the United States, Italy, Germany, Canada, Japan, China, etc. Cargill Dow Polymers
The company built a 10,000-ton/year polylactic acid biodegradable plastic production facility in Ballar, the United States. The device uses corn and other grains as raw materials, obtains lactic acid through fermentation, and then polymerizes it to produce biodegradable plastic polylactic acid. By the end of this year, the company plans to increase the production capacity of polylactic acid in the United States to 10,000 tons/year, and transfer the technology (_) with a view to building factories in Asia, Europe and South America. The production capacity is expected to reach 10,000 tons/year after this year. . By improving technology to reduce production costs, it is expected that by the end of the year, the production cost and sales price of polylactic acid will reach a level competitive with general thermoplastics. Cargill Dow Company cooperates with Italian companies and Taiwan's Wittmann Industries to promote the polymer rr polylactic acid produced by Cargil Dow Company and use it in packaging materials. rr
Resin packaging
The performance is equivalent to or even better than traditional petroleum-based polymer packaging materials. It has the advantages of high transparency, high gloss, etc., and has a long-lasting and pleasant fragrance, which can withstand extreme weather conditions. The fats and oils in some foods, and the heat sealing starting temperature is low (°C) and the strength is high. The material can be processed into films, rigid bottles and various containers, and can also be stretched and oriented, thermoformed, coated and printed using existing equipment. Invista Fisher also plans to industrialize its biodegradable polymerization process based on polylactic acid. The company has cooperated with the German B Institute of Agricultural Technology and Polymer Research ( In cooperation with the Academy of Sciences and with the support of the German Ministry of Agriculture, a starch-based technology production was developed. The company will invest 10,000 US dollars to build a ton/year inspection device in eastern Germany and plans to expand it to 1,000 tons/year. This process allows cereals, rye or wheat to be converted into lactic acid through continuous fermentation, and then polymerized and synthesized. The purification process adopts a membrane process. The company will produce fiber grades using the process within two years. This technology can be applied to devices up to 10,000 tons/year, with a production cost of approximately €/kg, while the production cost of a ton/year device is €/kg. Compared with other
engineering plastics, it also has better economic competitiveness. Japanese company C has developed a flame-retardant biodegradable plastic used in electronic industrial products. This material uses polylactic acid as the base resin and does not contain toxic additives. It is an environmentally friendly material. This product has passed two flame retardant tests in the United States. The added flame retardant is a safe and non-toxic inorganic material, which has opened up the application of biodegradable plastics in electronic products. This fuel material has a certain degree of heat resistance and can be formed using an injection molding machine. Its strength is equivalent to that of glass fiber reinforced polycarbonate. Company C has also developed biodegradable plastics with specifications for electronic applications. The material contains polylactic acid and a natural fiber called Zema. This material is used in electronic product packaging, which encapsulates silicon chips. It is said that no biodegradable plastic has previously achieved the heat resistance and rigidity required for electronic packaging, and the thermal deformation temperature of this fuel material is ℃, which is almost twice as high as that of the non-reinforced one (℃), and the flexural modulus. , which is also higher than that without enhancement. The fuel material will replace B and glass fiber reinforced B. A Japanese company has developed a method to produce lactic acid from glucose from food processing waste. This development project aims to convert the waste into monomers for biodegradable polylactic acid polymers. This process allows food processing waste or food waste to be saccharified using enzymes at about ℃ ~ ℃ to recover glucose. The glucose is then fermented to generate lactic acid under anaerobic conditions by adding cyanobacteria and ammonia. Within the year, the company will build a production facility with processing capacity of /r
. (_) Its industry has formed an industrial chain from heavy traffic road asphalt to oxidized asphalt to
waterproofing membranes from aromatic hydrocarbons
polyester polyols to
thermal insulation materials. > The industrial chain from epoxy resin to wind power resin to wind power materials, from dimethyl ether to new energy industry chain, from to non-fiber polyester industry chain. The complete industrial chain has laid a solid foundation for Pang?&r Qianyi'an New Materials (Petrochemical) Industrial Cluster&r. In the next step, Lingang New City New Materials Industrial Park will further develop the Yangtze River style, expand the carrier of industrial agglomeration, actively strive to start the construction of cofferdam projects, expand Strong production.. The biological/light dual-degradable masterbatch production line with an annual output of 10,000 tons was put into operation in Shandong Chunchao Color Masterbatch Co., Ltd. After years of research by Chunchao Color Masterbatch Co., Ltd., Chengfu has developed a high-performance biological/photodegradable masterbatch. When added to plastic films and disposable lunch boxes, the relative molecular mass will drop to below in about days. The masterbatch (_) is added with high-quality photodegradants, additives, and inorganic substances that have no impact on the environment, and is extruded by a twin-screw extruder. Due to its good dispersion and high whiteness, it does not affect the physical strength of plastic products. After testing by the National Environmental Protection Products Quality Supervision and Inspection Center, the degradation performance indicators comply with the /(degradable polyethylene film for packaging) standard, with longitudinal elongation of % and transverse elongation of .%. The price of plastic products processed with this masterbatch is %~% lower than that of ordinary plastics, and the physical and mechanical properties reach the standards of ordinary plastics. After degradation, they integrate with the soil and are non-toxic and harmless to the soil. At the end of the year, Asia's largest "photo-oxygen biodegradation technology" degradable plastic project with a total investment of RMB 100 million was settled in Jiyan, Jiangsu. The project is invested and constructed by Macau Jianhui Group. When the project is completed in 2019, it will have an annual production capacity of 10,000 tons of environmentally degradable plastic masterbatch, 10,000 tons of environmentally degradable plastic film, and 100 million environmentally degradable lunch boxes. "Photooxygen biodegradation technology" is the scientific research achievement of (_) Peking University for several years, and has been approved and recognized by the State Environmental Protection Administration. Biodegradable plastic products produced through special formulas can naturally degrade after being discarded and will not cause any pollution to the environment.
