什么是玉米淀粉材料?

What is corn starch material?
玉米淀粉塑料(主要用于塑料餐具、可降解一次性餐具等),是生物降解塑料聚乳酸(PLA)的一种,聚乳酸是以乳酸为主要原料聚合得到的聚合物,主要以玉米、木薯等为原料。是《关于公布聚己二酰丁二胺等107种可用于食品包装材料的树脂名单的公告》(卫生部2011年第23号)中的第53种物质。
Corn starch plastic (mainly used for plastic tableware, degradable disposable tableware, etc.) is a kind of biodegradable plastic polylactic acid (PLA). PLA is a polymer polymerized with lactic acid as the main raw material, mainly corn, cassava, etc. It is the 53rd substance in the announcement on publishing the list of 107 resins that can be used as food packaging materials, such as polyhexamethylene butylamine (No. 23, 2011, Ministry of Health).
聚乳酸的生产过程无污染,而且产品可以生物降解,实现在自然界中的循环,因此是理想的绿色高分子材料。
The production process of polylactic acid is pollution-free, and the product can be biodegradable, realizing the circulation in nature, so it is an ideal green polymer material.
聚乳酸(PLA)的优势:
Advantages of polylactic acid (PLA):
1、聚乳酸(PLA)是一种新型的生物降解材料,使用可再生的植物资源(如玉米)所提出的淀粉原料制成。淀粉原料经由糖化得到葡萄糖,再由葡萄糖及一定的菌种发酵制成高纯度的乳酸,再通过化学合成方法合成一定分子量的聚乳酸。其具有良好的生物可降解性,使用后能被自然界中微生物完全降解,生成二氧化碳和水,不污染环境,这对保护环境非常有利,是公认的
1. Polylactic acid (PLA) is a new type of biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Glucose is obtained from starch raw materials through saccharification, and then high-purity lactic acid is produced by fermentation of glucose and certain bacteria, and then polylactic acid with certain molecular weight is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature to generate carbon dioxide and water. It does not pollute the environment, which is very beneficial to environmental protection and is recognized
环境友好材料,真正做到“源于自然,归于自然”!
Environmentally friendly materials, truly "from nature, attributed to nature"!
2、聚乳酸适用于吸塑、注塑等各种加工方法,加工方便,应用十分广泛。可用于加工从工业到民用的各种食品容器、包装食品、快餐饭盒、无纺布、工业及民用布。进而加工成农用织物、保健织物、抹布、卫生用品、室外防紫外线织物、帐篷布、地垫面等等,市场前景十分看好。可见其机械性能及物理性能良好。
2. Polylactic acid is suitable for various processing methods such as blistering and injection molding, which is convenient for processing and widely used. It can be used to process all kinds of food containers, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics from industry to civil use. Then it is processed into agricultural fabrics, health care fabrics, rags, sanitary products, outdoor anti UV fabrics, tent fabrics, floor mats, etc., and the market prospect is very promising. It can be seen that its mechanical and physical properties are good.
3、相容性与可降解性良好。聚乳酸在医药领域应用也非常广泛,如可生产一次性输液用具、免拆型手术缝合线等,低分子聚乳酸作药物缓释包装剂等。
3. Good compatibility and degradability. Polylactic acid is also widely used in the pharmaceutical field, such as the production of disposable infusion equipment, detachable surgical suture, and low molecular polylactic acid as a drug slow-release packaging agent.
4、当焚化聚乳酸(PLA)时,其燃烧热值与焚化纸类相同,是焚化传统塑料(如聚乙烯)的一半,而且焚化聚乳酸绝对不会释放出氮化物、硫化物等有毒气体。人体也含有以单体形态存在的乳酸,这就表示了这种分解性产品具有的安全性
4. When polylactic acid (PLA) is incinerated, its combustion calorific value is the same as that of incinerated paper, which is half that of incinerated traditional plastics (such as polyethylene), and the incinerated PLA will never release toxic gases such as nitrides and sulfides. The human body also contains lactic acid in monomer form, which indicates the safety of this decomposition product
