可降解塑料袋實現(xiàn)的特點

來源:http://ssxx10.com/ 日期:2023-02-22

通過微生物來降解

Degraded by microorganisms
這種塑料袋是用一種可以被微生物分解的物質(zhì)做成的。例如用玉米淀粉做成的塑料袋,在細菌、真菌等微生物的作用下進行,能夠?qū)崿F(xiàn)塑料袋的分解功能,而且本身使用的原材料也來源于大自然,不會對環(huán)境造成污染。
This plastic bag is made of a material that can be decomposed by microorganisms. For example, plastic bags made of corn starch can be decomposed under the action of bacteria, fungi and other microorganisms, and the raw materials used are also from nature, which will not pollute the environment.
通過光學反應來降解
Degradation by optical reaction
這種塑料袋是通過在塑料中添加一些可以吸收紫外線光的物質(zhì),在自然界光照的條件下,不斷地碎片化、風化,然后降解成很小的分子,從而實現(xiàn)降解功能。這種類型的塑料袋降解有一定局限性,如果被埋在土里,接觸不到陽光就不能被降解。
This kind of plastic bag is used to realize the degradation function by adding some substances that can absorb ultraviolet light into the plastic, and constantly fragmenting and weathering under the conditions of natural light, and then degrading into very small molecules. This type of plastic bag degradation has certain limitations. If it is buried in the soil, it cannot be degraded without exposure to sunlight.

通過生物和光學反應共同作用來降解
Degradation through the joint action of biological and optical reactions
這種塑料袋在光學反應和生物降解的機理共同作用下,能夠適應不同的環(huán)境,從而大大增加塑料袋降解的進程。這種產(chǎn)品的制備難度較大,成本也比較高,目前還沒有大批量的上市。
This kind of plastic bag can adapt to different environments under the joint action of optical reaction and biodegradation mechanism, thus greatly increasing the process of plastic bag degradation. The preparation of this product is difficult and the cost is relatively high. At present, it has not been launched in large quantities.

總之,隨著科技的發(fā)展,相信未來會有更多采用材料產(chǎn)品的出現(xiàn)?,F(xiàn)在不光是塑料袋已經(jīng)用可降解材料來制作,還有一些購物袋、手提袋、包裝袋等都開始用材料制作。人們在享受便利的同時,也避免了使用后的塑料袋變成白色污染,給地球環(huán)境帶來沉重負擔。企業(yè)和個人都要響應號召,使用塑料袋產(chǎn)品,保護環(huán)境,給子孫后代留下一片綠水青山。
In short, with the development of science and technology, we believe that there will be more products using environmentally friendly materials in the future. Now not only plastic bags have been made of environmentally friendly biodegradable materials, but also some shopping bags, handbags, packaging bags, etc. have begun to be made of environmentally friendly materials. While people enjoy convenience, they also avoid the white pollution of plastic bags after use, which brings a heavy burden to the earth's environment. Enterprises and individuals should respond to the call of the state to use environmentally friendly plastic bags to protect the environment and leave a green landscape for future generations.
