The hottest PBS wins the first chance of industria

PBS wins the industrialization opportunity

aliphatic binary alkyd polyester (PBS) has become the most industrialized biodegradable plastic due to its excellent performance. Recently, PBS was officially shortlisted in the "Eleventh Five Year Plan" of the Ministry of science and technology of the people's Republic of China, becoming a fully biodegradable plastic that promotes industrialization at the national level. This is the first time that PBS has been officially recognized at the government level after it has been widely recognized by the industry. It is reported that the Ministry of science and technology of the people's Republic of China will launch the "Eleventh Five Year Plan" project for the industrialization of fully biodegradable plastics in advance at the end of this year. So far, PBS has successfully won the industrialization opportunity and become the leader in the industrialization of fully biodegradable plastics in China

various packaging materials made of PBS

have the most industrialized prospects

in fact, so far, the fully biodegradable plastics that have been developed have been expanded from the original pure polyhydroxyfatty acid esters (PHB) to polylactic acid (PLA), polycaprolactone (PCL) and aliphatic binary alkyd polyester (PBS)

pbs can stand out from many fully biodegradable plastics that have been closely studied by the aerospace industry. 1. What can thermoplastic composites do for them? Finally, PBS is listed in the "Eleventh Five Year Plan" of the Ministry of science and technology, which depends on the unique advantages and characteristics of PBS. In the author's opinion, PBS is the most comprehensive of all biodegradable polyester materials. Specifically, it can be analyzed from five aspects:

first, PBS polyester has good comprehensive properties. PBS polyester not only has mechanical properties close to PE and PP, which can meet the use requirements of general plastics, but also has very good processing properties, which can be used for all kinds of molding processing on general processing equipment. In addition, PBS polyester can only be degraded under composting conditions, and its performance is very stable during normal use

second, PBS polyester has excellent heat resistance. PBS polyester has the best heat resistance among fully biodegradable polyesters. The heat deformation temperature is close to 100 ℃ and can exceed 100 ℃ after modification. It can meet the heat resistance requirements of daily necessities and can be used to prepare cold and hot drink packaging and lunch boxes

third, PBS polyester has price advantages. It takes aliphatic dibasic acid and diol as the main raw materials. After large-scale production, the price can reach the level of PET polyester. Succinic acid and butanediol produced by biological fermentation are expected to further reduce the cost of raw materials

fourth, the production equipment of PBS with blue halo polyester has been localized. PBS polyester can be produced by slightly reforming pet and PBT polyester equipment. The localization of polyester equipment has laid a solid foundation for PBS polyester to form a new industry with independent intellectual property rights and international competitiveness. As long as the equipment can be localized, we are not afraid of competition from foreign multinational companies

fifth, PBS polyester is widely used. It can be used in the field of packaging, such as packaging films, lunch boxes, cosmetic bottles and drug bottles, electronic device packaging, etc; It can also be used in disposable utensils, such as disposable tableware, disposable medical supplies, etc. in addition, it can also be used in agricultural fields, such as agricultural films, pesticides and fertilizer slow-release materials; Finally, it can also be used in medical fields, such as biomedical polymer materials

broad industrial prospects

a large number of waste plastics, especially those that are difficult to recycle or cannot be recycled, provide a huge industrial market for PBS. According to the data, at present, about 50million tons of plastic waste are produced in the world every year. Calculated by 10%, the total amount of plastic waste that is difficult to recycle or cannot be recycled will reach 5million tons per year. The generation of many non recyclable plastic wastes does great harm to the environment, which will not only pollute farmland, tourist attractions, coastal ports, but also lead to biological ingestion and other events. These problems have aroused great concern and strong repercussions of the whole society. In addition, the 2008 Beijing Olympic Games has put forward the slogan of "Green Olympics", which puts forward higher requirements for plastic waste

recycling and degradation have been recognized as the ultimate solution to eliminate plastic waste. Plastic waste has the characteristics of large volume and stable performance. The traditional disposal methods of burial and incineration will bring serious environmental hazards. Developing recycling and reproduction technology is an effective measure to solve plastic pollution. For a large number of plastic wastes that account for 10% of the total plastic products and are difficult to recycle or can not be recycled, the effective way is to eliminate their impact on the environment through biodegradation. It is predicted that by 2010, the industrial scale of degradable plastics in the world will reach about 10% of the market share of the whole plastic products. Therefore, as a fully biodegradable plastic with the most industrialization prospect, the industrial development prospect of PBS will be particularly broad

degradation process of PBS products

industrialization speed up

at present, Japan Showa polymer company and Eastman company of the United States have carried out industrial production of PBS in the world, with production scales of 5000 tons/year and 15000 tons/year respectively. Specifically, in China, except for the high molecular weight PBS polyester produced by the National Engineering Research Center Co., Ltd. (hereinafter referred to as "Haier chemical") in the 10000 ton industrial plant, no other enterprises have achieved industrial production

this time, the Ministry of science and technology of the people's Republic of China launched in advance the "Eleventh Five Year" special plan for the industrialization of biodegradable plastics, whether it is a car factory or a battery factory, which can effectively solve the capital problem of China's PBS industrialization and make PBS a leader in the industrialization of biodegradable plastics

as the only enterprise in China that has the foundation for the industrialization of fully biodegradable plastics, helco chemical independently developed and successfully developed a fully biodegradable polymer material, which uses an efficient catalytic system and unique reaction control technology to simplify the synthesis process, reduce the synthesis cost of products, and ensure good material performance

according to the "Eleventh Five Year Plan" special plan, the state will rely on national scientific research institutions such as the Institute of physical and chemical technology of the Chinese Academy of Sciences, cooperate with equipment manufacturers, polyester production enterprises, product production enterprises, Haier Group and other product application enterprises to form a strong "National team" of China's fully degradable plastics industrialization, which is composed of scientific research institutions and enterprises

in this "national team", helco chemical will become a crucial platform for the transformation of achievements, which will directly affect the process and level of the industrialization of fully degradable plastics in China. According to the established plan, helco chemical will cooperate with domestic enterprises to invest 100million yuan in the early stage to develop a series of PBS polyester synthesis process, build a 5000 ton/year PBS polyester demonstration production line and a 3000 ton/year succinic acid fermentation demonstration production line, and build a world-class national recognized laboratory for degradation performance evaluation. On this basis, turning off the main motor source of the copper rod tensile testing machine, Haier chemical plans to realize the production capacity of 500000 tons/year of PBS polyester in China through technology transfer and technical cooperation, and form a new industry with an annual output value of 10billion yuan.
