可降解塑料的开展趋势

Development Trend of Degradable Plastics
运用淀粉的塑料:把脂肪族聚酯和淀粉混合在了一起,出产可降解塑料的技能也已经研讨成功。淀粉作为出产可降解塑料直接或直接的质料是非常重要的,除了玉米和红薯以外,木薯、西谷椰子、芋头等淀粉也可以被运用。
Plastics using starch: Aliphatic polyesters and starch are mixed together, and the skills for producing biodegradable plastics have been successfully explored. Starch as a direct or direct material for producing degradable plastics is very important. In addition to corn and sweet potatoes, cassava, coconut, taro and other starches can also be used.
在欧美,糊化淀粉和脂肪族聚酯的混合体被广泛用来出产垃圾袋等产品,淀粉只需有水,加热后就会糊化,具有可塑性,不过它的缺点是没有耐水功能,通过控制糊化淀粉和PCL结构,可以得到耐水性和机械物性优良的混合体。
In European and American countries, the mixture of gelatinized starch and aliphatic polyester is widely used to produce garbage bags and other products. Starch can be gelatinized and plasticized when heated only with water, but it has no water resistance function. By controlling the structure of gelatinized starch and PCL, a mixture with excellent water resistance and mechanical properties can be obtained.
依据不同的用途及环境条件,进一步深化研讨,并通过分子设计研讨改进配方、开发准时可控性环境降解塑料已成为许多的要点攻关课题。经归纳各种文献资料进行归纳,大体上可预测降解塑料往后的研讨与开发趋向:
According to different uses and environmental conditions, further research and improvement of formulation and development of timely controllable environmental degradable plastics through molecular design has become a key research topic in many countries. By summarizing various literature, the future research and development trend of degradable plastics can be predicted on the whole.
活跃研讨开发高效价廉光敏剂等,进一步进步可控性、快速降解性和彻底降解性。
Active research and development of high-efficiency and low-cost photosensitizers to further improve
controllability, rapid degradation and thorough degradation.
有利于一次性塑料废弃物的处理,一起保证取得丰厚的质料来源,以天然高分子、微生物组成高分子和具有生物降解性的组成高分子为质料,开发彻底生物降解塑料愈来愈受到重视。
It is conducive to disposal of disposable plastic wastes, and guarantees a rich source of material. With natural macromolecule, microbial macromolecule and biodegradable macromolecule as materials, the development of thorough biodegradable plastics has attracted more and more attention.
为加快降解塑料的开展,各国正致力于加快研讨和树立一致的降解塑料的界说、降解机理、评价办法和规范。
In order to speed up the development of degradable plastics, countries are working to speed up the study and establish a consistent definition, degradation mechanism, evaluation methods and standards of degradable plastics.
探究及培养能降解一般塑料的菌株,使现在广泛运用的一般塑料用后具有易降解性,以习惯环保要求;一起十分重视培养可出产聚酯的生物性植物等,以降低生物降解塑料的成本,有利于推广应用。
Explore and cultivate strains that can degrade general plastics, so that now widely used general plastics can be easily degraded to meet the requirements of environmental protection. Together, we attach great importance to the cultivation of polyester-producing biological plants, so as to reduce the cost of biodegradable plastics, which is conducive to the promotion and application of biodegradable plastics.
