一次性玉米淀粉餐具这种生物可降解餐具是以玉米、薯类、农作物秸秆等可再生资源为原料发酵生产出来,并进一步纯化聚合制备成的高纯度聚乳酸作为原料生产。下面我们就来简单讲一讲相关内容。
Disposable corn starch tableware this biodegradable tableware is produced by fermenting corn, potato, crop straw and other renewable resources, and further purifying and polymerizing the high-purity polylactic acid as raw material. Now let's talk about the related content briefly.
聚乳酸是可完全生物降解的生物基新材料代表,是目前性价比较高的生物可降解环保高分子材料,与传统的石油基材料相比,每吨聚乳酸可减排约3吨二氧化碳。这是因为聚乳酸具有良好的生物可降解性,经微生物完全降解然后生成二氧化碳和水。相比于普通塑料采用焚烧处理,造成大量温室气体排入空气中,聚乳酸从原材料到聚合物生产过程的碳排放是通用塑料聚乙烯的1/3左右。
Polylactic acid (PLA) is a representative of fully biodegradable new bio based materials. It is a biodegradable environmental friendly polymer material with high cost performance. Compared with traditional petroleum based materials, each ton of PLA can reduce about 3 tons of carbon dioxide. This is because polylactic acid has good biodegradability. It is completely degraded by microorganisms and then generates carbon dioxide and water. Compared with ordinary plastics, which are incinerated, a large number of greenhouse gases are discharged into the air. The carbon emission of polylactic acid from raw materials to polymer production is about 1/3 of that of general plastic polyethylene.
一次性玉米淀粉餐具
一次性玉米淀粉餐具在使用和生物降解过程中不产生有毒有害物质,具有一定耐菌性、阻燃性和抗紫外线性,可谓健康环保又。相比常见的可降解塑料,该餐具具有较好的热稳定性、力学性能,制成塑料袋更加耐用;又有优良的生物降解性,在堆肥条件下能够完全降解为水和二氧化碳,可有效减少白色污染。
Disposable corn starch tableware does not produce toxic and harmful substances in the process of use and biodegradation. It has certain bacteria resistance, flame retardancy and UV resistance. It is healthy, environmental friendly and safe. Compared with common degradable plastics, the tableware has better thermal stability and mechanical properties, and the plastic bag is more durable; It has excellent biodegradability and can be completely degraded into water and carbon dioxide under composting conditions, which can effectively reduce white pollution.
Advantages of disposable corn starch tableware:
无公害:由于它是玉米淀粉和其他环保材料精制而成,不含对人体有害的物质,可放心长期使用。
Pollution free: as it is refined from corn starch and other environmental protection materials, it does not contain substances harmful to human body, so it can be safely used for a long time.
零污染:产品埋入泥土中,在适宜的温度下,90天后可降解形成二氧化碳和水,对土壤和空气不造成污染。
Zero pollution: when the product is buried in the soil, it can degrade to form carbon dioxide and water after 90 days at a suitable temperature, without causing pollution to the soil and air.
省资源:玉米淀粉是可再生资源,取之不尽,用之不竭,而纸质餐具和塑料餐具需大量的木材和石油化工产品。以玉米淀粉为原料可节省大量的石油和森林资源。
Provincial resources: corn starch is a renewable resource, which is inexhaustible. Paper tableware and plastic tableware need a lot of wood and petrochemical products. Using corn starch as raw material can save a lot of oil and forest resources.
高品质:产品密织性好,耐水、耐油、防渗透,同时具有良好的耐高温和耐低温性,适合冰箱冷冻、冷藏、保鲜食品,微波炉加热等。
High quality: the product has good compactness, water resistance, oil resistance, anti permeability, and good high and low temperature resistance. It is suitable for freezing, cold storage, fresh-keeping food in refrigerator, microwave heating, etc.
此外普通塑料的处理方法依然是焚烧火化,造成大量温室气体排入空气中,而可降解玉米淀粉餐具则是掩埋在土壤里降解,产生的二氧化碳直接进入土壤有机质或被植物吸收,不会排入空气中,不会造成温室效应。
In addition, the treatment method of ordinary plastics is still incineration and cremation, resulting in a large number of greenhouse gases discharged into the air, while degradable corn starch tableware is buried in the soil for degradation, and the generated carbon dioxide directly enters the soil organic matter or is absorbed by plants, which will not be discharged into the air and will not cause the greenhouse effect.
