高直链淀粉玉米的发展前景

Development Prospect of High Amylose Corn
白色污染给人类生存环境带来难以估计的损失,这已引起全社会甚至全人类对环境保护的高度重视。面临日益干涸的石油资源,符合潮流的生物降解材料作为高科技环保产品正成为一个研发热门。降解塑料要进入市场必须到达以下要求:
White pollution has brought incalculable losses to human living environment, which has attracted great attention of the whole society and even the whole mankind to environmental protection. Facing the increasingly drying up of petroleum resources, biodegradable materials in line with the trend as high-tech environmental protection products are becoming a research and development hotspot. To enter the market, degradable plastics must meet the following requirements:
① 实用性,具有与同类一般塑料近似的应用功能;
(1) practicability, with similar application function to general plastics of the same kind;
② 降解性,在完结使用功能后能在自然环境中较快地降解,成为易被环境消纳的碎片,终究回归自然;
(2) Degradability, which can be degraded quickly in the natural environment after the use of the function, becomes debris easily absorbed by the environment, and eventually returns to nature;
③ 安全性,降解进程中和降解后的残留物对自然环境无害或无潜在损害;
(3) Safety, no harm or potential damage to the natural environment from the degradation process and residues after degradation;
④ 经济性,价格与同类一般塑料挨近或持平。
(4) Economy, price is close to or equal to that of similar plastics.
但是生物降解塑料的价格过高,降解塑料比同类现行塑料产品的价格高50%以上,其间能彻底降解的高出4倍~8倍,成为其推广应用的比较大障碍。为了下降成本,确保产品的降解功能,淀粉可生物降解塑料成为全国都在重视的热门产品。
But the price of biodegradable plastics is too high. The price of biodegradable plastics is more than 50% higher than that of the current plastics products of the same kind. During this period, the price of biodegradable plastics is 4 to 8 times higher than that of the current plastics products, which becomes the biggest obstacle to its popularization and application. In order to reduce the cost and ensure the degradation function of the products, starch biodegradable plastics have become a popular product in China.
淀粉是现在使用比较广泛的一类可彻底生物降解的多糖类天然高分子,具有质料来历广泛、价格低廉和易生物降解等长处,在生物降解材料范畴占有重要的地位。
Starch is one of the most widely used natural polysaccharides which can be completely biodegraded. It has many advantages, such as wide material history, low price and easy biodegradability. It occupies an important position in the field of biodegradable materials.
国内外发布的各种商标淀粉塑料的力学功能一般可以与同类应用的传统塑料相比,但其使用功能往往不尽善尽美,其首要缺陷之一是含淀粉的降解塑料耐水性都不好,湿强度差,一遇水其力学功能则严峻下降,而耐水性恰恰是传统塑料在使用进程中的长处。
The mechanical functions of various trademark starch plastics published at home and abroad can generally be compared with the traditional plastics used in the same kind of applications, but their use functions are often not perfect. One of the main defects of starch-containing degradable plastics is that their water resistance is not good, their wet strength is poor, and their mechanical functions are severely reduced in case of hydration. Water resistance is just the strength of traditional plastics in the use process.
高直链淀粉相对于一般淀粉有较好的抗水性、耐剪切性和成膜性,因此在塑料工业中的发展潜力巨大。
High amylose starch has better water resistance, shear resistance and film forming properties than common starch, so it has great potential in the development of plastic industry.
