可降解塑料有多种新型塑料:光降解型塑料、生物降解型塑料、光、氧化\生物全面降解性塑料、二氧化碳基生物降解塑料、热塑性淀粉树脂降解塑料。

There are many new types of Degradable Plastics: photodegradable plastics, biodegradable plastics, light, oxidation \ biological comprehensive degradable plastics, carbon dioxide based biodegradable plastics, and thermoplastic starch resin degradable plastics.
聚合物的可降解塑料是指因化学和物理因素引起的聚合的大分子链断裂的过程。聚合物曝露于氧、水、射线、化学品、污染物质、机械力、昆虫等动物以及微生物等环境条件下的大分子链断裂的降解过程被称为环境降解。降解使聚合物分子量下降,聚合物材料物性降低,直到聚合物材料丧失可使用性,这种现象也被称为聚合物材料的老化降解。
Polymer degradable plastics refer to the process of polymer macromolecule chain breaking caused by chemical and physical factors. The degradation process of macromolecular chain breaks of polymers exposed to oxygen, water, radiation, chemicals, pollutants, mechanical forces, insects and other animals, microorganisms and other environmental conditions is called environmental degradation. Degradation makes the molecular weight of polymer decrease and the physical properties of polymer materials decrease until the polymer materials lose their serviceability. This phenomenon is also called aging degradation of polymer materials.
聚合物的老化可降解塑料和聚合物的稳定性有直接关系。聚合物的老化降解缩短塑料的使用寿命。为此,自塑料问世以来,科学家就致力于对这类材料的防老化,即稳定化的研究,以制得高稳定性的聚合物材料,而各国的科学家也正利用聚合物的老化降解行为竞相开发环境降解塑料。
The aging of polymer degradable plastics is directly related to the stability of polymer. The aging and degradation of polymers shorten the service life of plastics. Therefore, since the advent of plastics, scientists have been committed to the research of anti-aging, i.e. stabilization, of such materials to prepare high stability polymer materials. Meanwhile, scientists from various countries are also competing to develop environmentally degradable plastics by using the aging degradation behavior of polymers.
可降解塑料的主要应用领域有:农用地膜、各类塑料包装袋、垃圾袋、商场购物袋以及一次性餐饮具等。
The main application fields of degradable plastics are: agricultural plastic film, various plastic packaging bags, garbage bags, shopping bags in shopping malls and disposable catering equipment.
可降解塑料原理:环境降解塑料的降解过程主要涉及生物降解,光降解和化学降解,这三种主要降解过程相互间具有增效、协同和连贯作用。例如,光降解与氧化物降解常同时进行并互相促进;生物降解更易发生在光降解过程之后。
Principle of Degradable Plastics: the degradation process of environmental degradable plastics mainly involves biodegradation, photodegradation and chemical degradation. These three main degradation processes have synergistic, synergistic and coherent effects. For example, photodegradation and oxide degradation often occur simultaneously and promote each other; Biodegradation is more likely to occur after the photodegradation process.
可降解塑料的优点分析:
Advantages of Degradable Plastics:
实用性:具有与同类普通塑料相当或相近的应用性能和卫生性能。
Practicability: it has the same or similar application performance and hygiene performance as the same kind of ordinary plastics.
降解性:在完成使用功能后,能在自然环境条件下较快降解,成为易被环境利用的碎片或碎末,回归自然。
Degradability: after the use function is completed, it can be rapidly degraded under natural environmental conditions, and become fragments or debris that can be easily used by the environment and return to nature.
安全性:降解过程中产生和降解后残留的物质对环境无害或无潜在危害。
Safety: the substances produced in the process of degradation and residual after degradation are harmless or have no potential harm to the environment.
经济性:价格与同类普通塑料持平或略高。
Economy: the price is equal to or slightly higher than that of similar ordinary plastics.
