可降解顆粒是製作的環保降解塑料的原料
可降解顆粒是製作的環保降解塑料的原料,它主要是利用植物秸杆等製成的對人體和環境友好的物品,不同於三大合成的塑料,廢棄後,在生物環境的作用下,可以自行分解,無論對人還是環境都無害,屬於綠色包裝可降解塑料袋是“能降解、易降解”的一種一次性購物袋。
Degradable particles are the raw materials of environmentally-friendly degradable plastics, which are mainly made of plant straw and other materials that are friendly to human body and environment. They are different from the three synthetic plastics. After being discarded, they can decompose themselves under the action of the biological environment, and are harmless to both people and the environment. They belong to green packaging. Degradable plastic bags are disposable shopping bags that are "degradable and easy to degrade".
可降解塑料通過優化選擇生產原料和製作工藝,在數天或幾個月的日曬雨淋及微生物的共同作用下,能逐步分解成碎片,終全部降解。可降解塑料的原材料主要有:聚乳酸、聚羥基脂肪酸酯、二氧化碳共聚物、澱粉、改性澱粉或其它纖維素、光敏劑、生物降解劑等。
By optimizing the selection of production materials and production process, degradable plastics can be gradually decomposed into fragments and finally completely degraded under the joint action of several days or months of sunshine, rain and microorganisms. The raw materials of degradable plastics mainly include polylactic acid, polyhydroxy fatty acid ester, carbon dioxide copolymer, starch, modified starch or other cellulose, photosensitizer, biodegradable agent, etc.
目前,可降解塑料的原材料主要有:
At present, the main raw materials of degradable plastics are:
聚乳酸(PLA),它是由植物糖分提取的丙交酯單體聚合而成,在工業堆肥下可完全降解為水和二氧化碳。
Polylactic acid (PLA), which is polymerized from lactide monomer extracted from plant sugar, can be completely degraded into water and carbon dioxide under industrial composting.
聚羥基脂肪酸酯(PHA),聚羥基脂肪酸酯(PHA)是由微生物通過各種碳源發酵而合成的不同結構的脂肪族共聚聚酯,不僅能夠用於包裝材料、農膜等,還能廣泛的應用於藥品、化妝品、動物飼料等領域。
Polyhydroxy fatty acid ester (PHA) and polyhydroxy fatty acid ester (PHA) are aliphatic copolyesters with different structures synthesized by microorganisms through fermentation of various carbon sources. They can be used not only in packaging materials, agricultural films, but also in medicine, cosmetics, animal feed and other fields.


二氧化碳共聚物(PPC),外觀與聚乙烯塑料相似,彈性良好,在土壤中可在短時間內完全降解,並直接被植物吸收利用。
Carbon dioxide copolymer (PPC), similar in appearance to polyethylene plastic, has good elasticity, can be completely degraded in soil in a short time, and can be directly absorbed by plants.
其他添加劑,在塑料包裝製品的生產過程中加入一定量的添加劑(如澱粉、改性澱粉或其它纖維素、光敏劑、生物降解劑等),使塑料的穩定性下降,較容易在自然環境中降解。
Other additives: add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradable agent, etc.) in the production process of plastic packaging products to reduce the stability of plastics and make them easier to degrade in the natural environment.
