一次性玉米淀粉餐具生產中需要解決的問題
一次性玉米淀粉餐具是以淀粉等無機大分子天然物質和一些無機鹽為原料添加的新型樹脂,具有紫外線活化產生的自由基氧化和生物降解作用(即霉菌的微生物分解)。
Disposable corn starch tableware is a new type of resin added with starch and other inorganic macromolecular natural substances and some inorganic salts as raw materials, which has the free radical oxidation and biodegradation caused by UV activation (namely the microbial decomposition of mold).
可生物降解共聚物的共混作為當前高科技領域研究的主要方向,已成為研究的熱點。技術領域競爭的是增加盡可能多的降解物質。保持塑料原有的物理力學性能和合理的。
Blending of biodegradable copolymers, as the main research direction in the high-tech field, has become a research hotspot. The focus of competition in the field of technology is to increase as many degradation substances as possible. Keep the original physical and mechanical properties and reasonable price of plastics.
降解共聚物在一次性玉米淀粉餐具中,在任何小的部分,其較好的空間結構,如在降解物質被降解時,整個物質被分解成單個破碎的幾何形狀,而這些幾何形狀的分子量大大降低,容易被大自然消耗。在實際操作過程中,解決:
Degradation copolymers in disposable corn starch tableware, in any small part, its better spatial structure, for example, when degradation materials are degraded, the whole material is decomposed into a single broken geometry, and the molecular weight of these geometry is greatly reduced, which is easy to be consumed by nature. In the actual operation process, the key solution is:
一個是降解材料和整個材料之間的力。因為在化學變化中它不是共價鍵力或離子鍵力,而且牛頓的萬有引力遠遠不能滿足產品強度的要求。因此,在微觀空間中使其盡可能成為分子間的問題就解決了。這是難降解共聚物形成的個難點。
One is the force between the degradation material and the whole material. Because it is not covalent bond force or ionic bond force in chemical change, and Newton's gravity is far from meeting the requirements of product strength. Therefore, the problem of making it as intermolecular as possible in the micro space is solved. This is the first difficulty in the formation of the refractory copolymers.
二是解決降解材料與整體材料的不相容問題。以淀粉和PE為例。前者為強極性分子,后者為非極性分子。兩者并不兼容。解決方法是在兩者之間加入交聯(lián)劑、偶聯(lián)劑、表面活性劑等物質,這是制備可降解共聚物的兩個難點。
The other is to solve the problem of incompatibility between the degradation material and the whole material. Take starch and PE for example. The former is strongly polar and the latter is nonpolar. The two are not compatible. The solution is to add cross-linking agent, coupling agent, surfactant and other substances between them, which are two difficulties in the preparation of degradable copolymers.
