聚乳酸(可降解塑料)则是另一种应用广泛的可生物降解聚合物树脂,和PBAT具有完全相反的力学性能,因此,利用共混法将两者制成共混物是性能互补的有效手段,且所得共混材料和制品具有完全的可生物降解性。
Polylactic acid (degradable plastic) is another widely used biodegradable polymer resin, which has completely opposite mechanical properties to PBAT. Therefore, blending the two into a blend by blending method is an effective means to complement each other, and the resulting blend materials and products have complete biodegradability.
聚乳酸(可降解塑料PLA)是一种新型的可降解塑料,由可再生植物资源(如玉米)衍生的淀粉制成。将淀粉原料糖化得到葡萄糖,然后将葡萄糖和一定的发酵生产高纯度的乳酸,再通过化学合成的方法合成一定分子量的聚乳酸。它具有良好的生物降解性,使用后可被自然界的微生物完全降解,终生成二氧化碳和水,不污染环境,非常有利于环境保护,是公认的环保材料。
Polylactic acid (PLA) is a new type of degradable plastic, which is made of starch derived from renewable plant resources (such as corn). Glucose is obtained by saccharifying starch raw materials, and then glucose and a certain amount of fermentation are used to produce high-purity lactic acid, and then polylactic acid with a certain molecular weight is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by natural microorganisms, and finally generate carbon dioxide and water. It does not pollute the environment. It is very conducive to environmental protection. It is recognized as an environmental protection material.
普通塑料的处理方法仍然是焚烧和火化,造成大量温室气体排放到空气中,而聚乳酸塑料则埋在土壤中降解,产生的二氧化碳直接进入土壤有机质或被植物吸收,不会排放到空气中,不会造成温室效应。
The treatment method of ordinary plastics is still incineration and cremation, resulting in a large number of greenhouse gases discharged into the air, while polylactic acid plastics are 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 temperature chamber effect.
可降解颗粒
良好的机械和物理性能。聚乳酸适用于吹塑、热塑性塑料等各种加工方法。从工业到民用,可用于加工各种塑料制品、包装食品、快餐饭盒、无纺布、工业和民用织物。然后加工成农用面料、保健面料、抹布、卫生用品、户外防紫外线面料、帐篷面料、地垫等,市场前景十分广阔。
Good mechanical and physical properties. Polylactic acid is suitable for blow molding, thermoplastic and other processing methods. From industry to civil use, it can be used to process all kinds of plastic products, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics. Then it is processed into agricultural fabrics, health fabrics, rags, sanitary products, outdoor anti ultraviolet fabrics, tent fabrics, floor mats, etc. the market prospect is very broad.
良好的相容性和降解性。聚乳酸在医学上的应用也很广泛,例如可用于生产一次性输液工具、可拆卸手术缝合线,低分子量聚乳酸用作的缓释包装剂。
Good compatibility and degradability. Polylactic acid is also widely used in medicine. For example, it can be used to produce disposable infusion tools, detachable surgical sutures, and low molecular weight polylactic acid can be used as sustained-release packaging agent.
虽然可降解颗粒的塑料目前在塑料总规模中的占比还微乎其微,但是产业也已经发展了多年,其中哪些品种受市场重视实际已经有了,不过我们还是希望深入分析其中的原因,以便对未来展望。PLA与其他可降解塑料相比,在一些方面并没有优势,但是硬度和透明性上PLA却具有的性能。
Although the proportion of degradable granular plastics in the total scale of plastics is still very small, the industry has also developed for many years, and which varieties have been paid attention to by the market. However, we still hope to deeply analyze the reasons in order to look forward to the future. Compared with other degradable plastics, PLA has no advantages in some aspects, but it has better properties in hardness and transparency.
