Biodegradable polyesters mainly include aliphatic groups derived from bio-based materials,
And bio-based, fossil based aliphatic, aliphatic – aromatic copolyesters
(PBST, PBAT), etc.In the past 10 years, the development speed of its technology research and industrialization is obviously faster than that of traditional polyester (PET and PBT).Especially in China, the continuous growth of individual production capacity has greatly reduced costs, promoted the progress of synthetic technology and attracted the attention of investors.
In addition, with the improvement of people’s economic living standard and the continuous improvement of relevant national regulations, biodegradable polyester in fiber (nonwoven), “use and discard” packaging, domestic garbage bags, agricultural film, disposable medical devices,
Fields such as high value-added human body affinity medical materials are playing an increasingly important role. It is precisely because of the continuous expansion of these application fields that biodegradable products are also promoted
Development of degradation polyester technology and industrialization.There are three key evaluation indexes for the synthesis of biodegradable polyester monomer raw materials: first, the process of obtaining monomer raw materials should not have a negative impact on the environment;Second, the monomer itself should have safety (low toxicity);The third is to have relatively low economic cost as far as possible, so that the synthetic product has a reasonable commercial push
Extensive value.Some aliphatic biodegradable polyesters are prepared by polycondensation of ring-opening ester monomer, and tin catalysts are mostly used in industrial production. Such catalysts have a high cost, and the residue of tin catalysts in polymers will be in polyester organisms
The negative effects of degradation on humans (cytotoxicity) and the environment have limited the wide application of these polymers to some extent.With the growth of biodegradable polyester application demand, relatively efficient, low cost,
Research and development of catalysts with low contamination and high safety after degradation residues
Progress is also being made.There are also relevant academic and industrial research progress on plasticizers used for biodegradable polymers at home and abroad. Citric acid ester plasticizers can effectively reduce the glass transition temperature of PLA, improve its processing performance, reduce brittle fracture, and improve product toughness.The addition of polyethylene glycol ether can increase the flexibility of PLA.Epoxy vegetable oil (epoxy-soybean oil, soybean oil, rice bran oil, etc.) is itself a biodegradable environmental protection additive, which can replace biotoxicity
Phthalic plasticizer, improve the processing properties of materials;Phosphate ester can not only improve the processing performance of polymer by transesterification, but also can be used as flame retardant to give polymer more functions.Isosorbitol on PLA
The effect of plasticizing modification was obvious, and the crystallization property of PLA was also improved.Biodegradation environment must have four basic conditions: 1
Different kinds of microorganisms;② With the right amount of oxygen, water and minerals
Mass;(3) There is an appropriate temperature (20-60 ℃);(4) it has an appropriate pH value
(5 ~ 8).The biodegradability of plastics was evaluated in the early stage by the method of resistance to microbial growth, which was then measured as the final product of microbial metabolism
(CO2 or CH4).Annual output of 30,000 tons of biodegradable polyester and its products project energy saving report outline (according to the national requirements outline preparation) specific search free consultation.First chapter annual output of 30000 tons of biodegradable polyester and its products rebuilding manual section 1 annual output of 30000 tons of biodegradable polyester and its products renovation evaluation purpose and meaning in the second quarter of 30000 tons of biodegradable polyester and its products the redevelopment of the assessment on the basis of the third quarter, annual output of 30000 tons of biodegradable polyester reconstruction evaluation range and content of the fourth quarter and its productsWork Procedure for reconstruction evaluation of biodegradable polyester and its products with an annual output of 30,000 tons Chapter 2 Project Overview With an annual output of 30,000 tons Biodegradable polyester and its products Section 1 Project Overview Section 2 Natural Conditions of the Project Section 3 Project Construction Scheme with an annual output of 30,000 tons Biodegradable polyester and its products Section 4Annual output of 30000 tons of biodegradable polyester and its products project can use Section 5 Annual output of 30000 tons of biodegradable polyester and its products rebuilding major energy-using equipment selection in the third chapter annual output of 30000 tons of biodegradable polyester and its products the redevelopment of the energy supply situation analysis evaluation of social development, where the project is located in the first quarter and resource conditions in the second quarterSection 3 Influence of energy consumption in the locality of the Project on local energy consumption.Chapter IV Energy conservation Assessment of Project Construction Scheme with annual output of 30,000 tons of biodegradable polyester and its Products Section 1 Energy conservation Assessment of Project site selection and general layout Section 2 Energy conservation assessment of Project Process and Technical Scheme Section 3 Energy conservation assessment of Main Energy-using processes and Processes Section 4 Energy Conservation Assessment of Main Energy-consuming Equipment Section 5Energy Conservation Assessment of Auxiliary production and Ancillary Production Facilities Section 6 Project Assessment of 30,000 tons of Biodegradable Polyester and its Products Section 5 Energy Consumption and energy efficiency Assessment of 30,000 tons of Biodegradable Polyester and its Products Section 1 Energy Consumption Type, Source and Consumption Assessment section 2Evaluation of energy processing, conversion and utilization of projects with an annual output of 30,000 tons of biodegradable polyester and its products Section 3 Analysis and evaluation of energy efficiency Level of projects with an annual output of 30,000 tons of biodegradable polyester and its products Section 4 Evaluation of projects with an annual output of 30,000 tons of biodegradable polyester and its products Section 6Annual output of 30000 tons of biodegradable polyesters and evaluating products rebuilding energy-saving measures in the first quarter yearly produces 30000 tons of biodegradable polyesters and evaluating products project energy saving measures in the second quarter of 30000 tons of biodegradable polyester and its products project energy saving management evaluation of the third quarter, annual output of 30000 tons of biodegradable polyester and its products project evaluation section in chapter 7Conclusion of the project with an annual output of 30,000 tons Biodegradable polyester and its products Chapter 8 Problems and Suggestions of the project with an annual output of 30,000 tons biodegradable polyester and its products Can be consulted free of charge in the early stage of the specific project.Feasibility study report of annual output of 30,000 tons biodegradable polyester and its products project
